My Feelings on English language :: essays research papers

My feelings about the English language, including both grammar and literature, have changed several times throughout my life. These changes took place as I was influenced by my family and by the different teachers that I have had throughout my academic career. As a young boy, I knew very little about the English language, but the instruction which I have received throughout my academic career has worked to shape my feelings about the English language. My parents began reading to me when I was very young. When I was only six months old, my parents bought me a number of plastic books. Using simple picture books, my parents taught me to recognize pictures of objects and how to associate those objects with their specific names. I learned how to talk when I was only a year old, and my parents continued to read to me in order to help me build up my vocabulary. I specifically remember my mother reading Sesame Street books to me. When she read to me, she used a different voice for each of the characters. I heard the same stories read to me so many times that I began to memorize them. I was able to recite my favorite stories before I could read them for myself. While I was unable to read, my skills with the English language were developing as I learned and used the words that I heard my parents read to me. My parents, my first teachers, made learning the English language an enjoyable experience for me at a young age.  Ã‚  Ã‚  Ã‚  Ã‚   I began attending preschool at the age of three, and I have a number of memories from that period in my life. My preschool teachers made learning about the English language fun. They ingrained in me the letters of the English alphabet using a number of techniques. I remember gluing uncooked macaroni noodles onto construction paper in order to form different letters of the alphabet. The letters or words that we learned were usually associated with a fun story or with a specific color. The teachers also read a great deal to me and my fellow classmates. Story-time became something that I looked forward to. Because my preschool teachers made learning fun, I looked forward to learning more about the English language at a very young age. My parents further reinforced what I learned in preschool by continuing to read to me at home.

Location: Rome, Italy :: essays papers

Location: Rome, Italy Architect: Giacomo Barozzi da Vignola; born 1507, died 1573. His career illustrates the rigidity of Mannerist art in the later half of 16th century. His design of Il Gesu meant that Jesuit missionaries carried copies of his design all over the world. His first major work was the villa (Rome) built for Pope Julius III, but Il Gesu was the most influential, although considered architecturally less adventurous. Vignola published his own treatise, Regola delli Clinque Ordini d'Architettura in 1562. It became the standard textbook for architectural students, mainly in France, for about three centuries and nearly two hundred editions of it are known. Towards the end of his life, he built a gateway for the Farnese Gardens in Rome. The gateway was demolished in 1880, but stones were preserved and it has been rebuilt. Builder: Giovanni Tristano Construction Date: began 1958 (factual). Resource type: Church Style/Culture: Italian Renaissance Description and Features: Il Gesu displays a tunnel-vaulted nave (about 60 feet wide) and has four chapels on each side. The end walls are aligned with the outer walls of the chapels. The tunnel vault rises above the cornice that runs from the faà §ade to the piers of the crossing. Due to the faà §ade windows and the lunettes of the tunnel-vault, the nave is brightly lit, but in contrast, the chapels are dim. The diameter of the dome is equal to the width of the nave. Vignola accomplished this by having the chapels in the form of a continuous row into the piers of the crossing. The dome seemed to rest on surrounding walls, not on the three dimensional piers. The small chapels formed a passage in-between the nave and the transept. Original Use: Il Gesu is the Roman mother-church of the Jesuit Order Construction History: On June 26, 1568 the foundation stone was laid out, although it took years to finally decide on its situation, shape and size. Nanni di Baccio Bigi had submitted a design for the church in 1550, and Michealangelo was called in to design it in 1554, but Vignola's designs were approved. The construction finally started when Cardinal Alessandro Farnese made a large financial contribution in 1586. Giovanni Tristano, a Jesuit father, and an architectural expert, who worked on other Jesuit churches prior to Il Gesu, directed the building. It is assumed that by 1571, Vignola's plans did not satisfy Tristano, because Giacomo della Porta was called to design the faà §ade.

Effects of Anthrax essays

Effects of Anthrax essays It seems like now a day there is tragedies, attacks, and new diseases that spring up constantly. Most recently, the American nation is plagued by a deadly epidemic Anthrax. Anthrax is a topic that is all over the newspapers, magazines, and television, but common people know very little of Anthraxs causes and effects. There are many myths and stories that are spread through rumors and false information. All people and especially those near at risk areas must be informed about the truth of Anthrax. Anthrax is a disease that is formed from a deadly bacterium that originates most commonly in dead animals, but unfortunately it can also be developed and produced in highly sophisticated labotories and scientific environments of that nature. Anthrax is being widely distributed in the United States of America through postal offices and governmental work areas. Not only do all people need to know about cures and vaccinations of this disease, but also background information and knowledge of this deadly disease must be widely distributed to give all people an understanding and precaution of this lethal and easily infected illness. The lethal bacterium, Bacillus anthracis, which causes the disease Anthrax, was not discovered until 1959. Anthrax can appear in humans and animals alike. It was first discovered in mysterious dead animals. At first, scientists believed that this bacterium, Bacillus anthracis, blocked the capillaries, which furthermore resulted in death. Through many experiments and observations, scientists discovered that blocked capillaries did not cause death, but the deadly and dangerous exotoxin released by Anthrax. This toxin is extremely deadly and lethal. The cause of death from this Anthrax toxin is due to lack of oxygen, respiratory shock and failure, secondary shock, cardiac arrest, and an increase of vascular permeability. Anthrax can be contracted in three different ways. First and most dea...

Self Perspective Essay Example

Self Perspective Essay Example Self Perspective Paper Self Perspective Paper The Positives and Negatives Is self- Identity created over time, or are we born with It? Self identity, also known as self concept, self perspective or self construction refers to how a person university of Texas In Austin, Texas. In their article Self Verification 360 degrees: Illuminating the Light and Dark Sides they explain the self verification theory. North and Swan explain, Self verification theory asserts that people are motivated to seek confirmation of their negative as well as positive self-views (n. Page). They also note, Because self views serve these vitally important functions, people become invested in maintaining them (n. Page. ). George Orwell is an English journalist and novelist. His book, Down and out in Paris and London, Documents the life of the lower class people in Paris and London in the 1 us. Of these people, Boris creates his self-identity through being overly optimistic, Bozo creates his self-identity through being an artist, Payday creates his-self Identity through his self-pity and Charlie is through his lies. Boris, Bozo, Payday and Charlie all do not match up with Swan and Norths self- reification theory. Then enters Boris, Boris was a Russian waiter. He is by nature overly optimistic and creates his self-identity though it. Boris explains, l have always said it, there is nothing easier to get than money (Orwell 44). ). If money was so easy to get then he wouldnt be in the situation that he is in. Most times he says things that are obviously untrue such as, Boris states, Oh we shall find something. I have got a few cards up my sleeve. There are people who owe me money, for instance-Paris is full of them (Orwell 29). If there were really people all over Paris that owed him money then e would be collecting the money. Boris also states, What things a man can do with brains! Brains will make money out of anything (Orwell 31). There he goes again with being overly optimistic he has a brain but has gone days without eating before. When Orwell first meets up with Boris one of the first few words out of his mouth was starving to death is this goes on much longer (Orwell 28). Swan and Norths self verification theory, assumes that people work to preserve their negative as well as positive self views by seeking confirmation for these self One time in particular Orwell goes into description about Boris regimen to get ready. Orwell says, He shaved without soap and with a razor- blade two months old, tied his tie so that the holes did not show, and carefully stuffed the soles of his shoes with newspaper (30). Orwell also notes, Finally when he was dressed, he produced an ink bottle and Inked the skin on his ankles where It showed through his socks (30). The fact that Boris goes to such extreme lengths to make himself look presentable says a lot about how he wants people to perceive him. He wants his self Image on the outside to look as good as possible when fledgling a Job. Other than the times he gets dressed up to look for his past mistresses and tells them about his misfortune. Orwell says, Sometimes in hopeful moments Boris spent fifty centimes on a stamp and wrote to one of his ex mistresses, asking for money'(34). Boris doesnt fit Swan and Norths theory because he doesnt try to get confirmation from people he Just does as he wants. Hes not ashamed of being poor. Bozos self-identity is created through having no self pity. He has a mangled leg and earns a little bit by drawing chalk paintings on sidewalks. He struggles inside the roll of desperate poverty so he can have some sense of dignity. He wore the usual beggars clothes but wore a collar and tie and was proud to wear it. Orwell writes, The collar a year or more old, was constantly going around the neck, and Bozo used to patch it with bits cut from the tail of his shirt so that the shirt had scarcely any tail left. (166). Orwell notes, His damaged leg kept getting worse and was going to have to be amputated one day (166). Orwell also says, With all this, he had neither fear, nor regret, nor shame, nor self pity. Orwell 166) Bozo explains, Being a beggar, he said, was not his fault (Orwell (166). Bozo cared about what others thought of him as he was constantly fixing his collar. He was also always reminding Orwell that he wasnt just someone who begged for money (167). Orwell states that, He considered himself in a class above the ordinary run of beggars, who he said, were an abject lot, without even the decency to be ungrateful (16 7). Even though Bozo was a beggar, in a way he felt he was better than all the other beggars. He had no self pity on himself. He provided a service than rather than Just a jugular beggar. The people didnt pay him to go away he got paid for his services. Bozo doesnt match up with Swan and Norths theory, Self verification theory asserts that people are motivated to seek confirmation of their negative as well as positive self-views (n. Page. ). Bozo wants people to look at the positives about him. He doesnt want people to seek confirmation on the negative views about himself. Then enters Payday, he creates his self-identity through his self pity. He was dressed better than most tramps he wore a tweed shooting Jacket and a pair of old evening trousers with the braid still on them (Orwell 149). The braid that was still on his pants in his mind was a lingering scrap of respectability he made sure when it was loose to sew it back on (Orwell 149). He tried to keep up his appearance as much as possible he carried a razor and a boot brush that he would not sell (Orwell 150). He had sold some of his other belongings such as his pocket knife and his papers but wouldnt sell his boot brush or razor. Even though Orwell says Payday was horribly ashamed being a tramp he still ad picked up all the little tricks that all tramps did (150). When they walked by a vending machine he would pull the lever to make sure that no loose change came out and he never missed a cigarette end on the ground. Even though he was horrible ashamed of being a tramp, in public he still did all these little things that tramps did. Payday doesnt fit the theory of the Texas University Professors Swan and North, Self verification assumes that people work to preserve their negative as well as positive seeking confirmation for these self views. As Orwell writes about Payday he says, The thought of his bad luck never seemed to leave him for an instant (152). Payday is always is so negative that he doesnt fit Swan and Norths theory. Payday never gives anyone anything positive to seek confirmation of; he is always talking about all the negatives in his life. Charlie is a young man who seeks his self identity through being the center of attention. Orwell explains, He was a youth of family and education who had run away from home and lived on occasional remittances (10). Charlie would bang on the zinc bar and yell for silence (96). The stories Charlie told were not always to be awaken seriously. Charlie wanted to be liked but by the public as he always wanted to be the center of attention but his stories werent any nature to be liked. Charlie says At twenty -two I am utterly worn out and finished (Orwell 10). He tries to make him sound older and worldly than he actually is. Charlie goes into his story of him drugging his brother and robbing him of all his money (Orwell 11). Then with the money he got a guide and wanted to go to the borders (Orwell 12). He basically goes on to say he paid money and got to do whatever he wanted with a girl. Which is he ultimately raped her. (Orwell 13). Charlies story was disgusting. He wanted to be the center of attention and always be telling stories. Even though everyone knew they were most likely not true. Charlie does not go with Swan and Norths self verification theory of people are motivated to seek confirmation of their negative as well as positive self- views (n. Page. ). Charlie doesnt really care what people think he Just wants to tell his stories and wants people to listen to him. In conclusion, the book Down and Out in Paris and London by George Orwell, ho is an English Journal and Novelist had a few interesting characters. Self-identity is created over time as we are not born with it. Boris creates his self identity through being optimistic and tries to get self verification through talking about positive things about himself as well as the negative things about himself. Bozo is a street artist also known as a Screener; he creates his self-identity by having no self pity even though his life is never going to get any better. Bozo is always looks on the bright side of everything. Payday creates his self identity though having self pity. Payday is a man who is quite ashamed of being a tramp. But he still has picked up all of the tramps little tricks throughout his time and doesnt try to hide them.. At last there is Charlie he is a young man from money and education. Charlie created his self identity through being a liar. He is also quite a story teller. Ultimately Charlie, Bozo, Payday and Boris do not match up with Swan and Norths Self Verification theory of, people are motivated to seek confirmation of their negative as well as positive self- views (n. Page). Can one change their self identity multiple times throughout their life?

Queen Victorias Golden Jubilee Celebrations

Queen Victorias Golden Jubilee Celebrations Queen Victoria reigned for 63 years and was honored by two great public commemorations of her longevity as ruler of the British Empire. Her Golden Jubilee, to mark the 50th anniversary of her reign, was observed in June 1887. European heads of state, as well as delegations of officials from throughout the empire, attended lavish events in Britain. The Golden Jubilee festivities were widely seen not only as a celebration of Queen Victoria but as an affirmation of Britains place as a global power. Soldiers from throughout the British Empire marched in processions in London. And in the distant outposts of the empire celebrations were also held. Not everyone was inclined to celebrate the longevity of Queen Victoria or the supremacy of Britain. In Ireland, there were public expressions of protest against British rule. And Irish Americans held their own public gatherings to denounce British oppression in their homeland. Ten years later, Victorias Diamond Jubilee celebrations were held to mark Victorias 60th anniversary on the throne. The 1897 events were distinctive as they seemed to mark the end of an era, as they were the last great assemblage of European royalty. Preparations for Queen Victorias Golden Jubilee As the 50th anniversary of Queen Victorias reign approached, the British government felt that a monumental celebration was in order. She had become queen in 1837, at the age of 18, when the monarchy itself had seemed to be coming to an end. She had successfully restored the monarchy to where it occupied a preeminent place in British society. And by any accounting, her reign had been successful. Britain, by the 1880s, stood astride much of the world. And despite small-scale conflicts in Afghanistan and Africa, Britain had essentially been at peace since the Crimean War three decades earlier. There was also a feeling that Victoria deserved a great celebration as she had never celebrated her 25th anniversary on the throne. Her husband, Prince Albert, had died young, in December 1861. And the celebrations which likely would have occurred in 1862, which would have been her Silver Jubilee, were simply out of the question. Indeed, Victoria became fairly reclusive after Alberts death, and when she did appear in public, she would be dressed in widows black. In early 1887 the British government began making preparations for the Golden Jubilee. Many Events Preceded Jubilee Day in 1887 The date of large public events was to be June 21, 1887, which would be the first day of the 51st year of her reign. But a number of associated events began in early May. Delegates from British colonies, including Canada and Australia, gathered and met with Queen Victoria on May 5, 1887, at Windsor Castle. For the next six weeks, the queen participated in a number of public events, including helping to lay the cornerstone for a new hospital. At one point in early May, she expressed curiosity about an American show then touring England, Buffalo Bills Wild West Show. She attended a performance, enjoyed it, and later met cast members. The queen traveled to one of her favorite residences, Balmoral Castle in Scotland, to celebrate her birthday on May 24, but planned to return for London for the major events which would take place close to the anniversary of her accession, June 20. The Golden Jubilee Celebrations The actual anniversary of Victorias accession to the throne, June 20, 1887, began with a private commemoration. Queen Victoria, with her family, had breakfast at Frogmore, near the mausoleum of Prince Albert. She returned to Buckingham Palace, where an enormous banquet was held. Members of various European royal families attended, as did diplomatic representatives. The following day, June 21, 1887, was marked with lavish public spectacle. The queen traveled by a procession through the streets of London to Westminster Abbey. According to a book published the following year, the queens carriage was accompanied by a bodyguard of seventeen princes in military uniform, superbly mounted and wearing their jewels and orders. The princes were from Russia, Britain, Prussia, and other European nations. The role of India in the British Empire was emphasized by having a troop of Indian cavalry in the procession close to the queens carriage. Ancient Westminster Abbey had been prepared, as galleries of seats had been built to accommodate 10,000 invited guests. The service of thanksgiving was marked by prayers and music performed by the abbeys choir. That night, illuminations lit the skies of England. According to one account, On rugged cliffs and beacon hills, on mountain peaks and lofty heaths and commons, great bonfires blazed. The next day a celebration for 27,000 children was held in Londons Hyde Park. Queen Victoria paid a visit to the Childrens Jubilee. All the children attending were given a Jubilee Mug designed by the Doulton company. Some Protested the Celebrations of Queen Victorias Reign Not everyone was favorably impressed by the lavish celebrations honoring Queen Victoria. The New York Times reported that a large gathering of Irish men and women in Boston had protested the plan to hold a celebration of Queen Victorias Golden Jubilee at Faneuil Hall. The celebration at Faneuil Hall in Boston was held on June 21, 1887, despite pleas to the city government to block it. And celebrations were also held in New York City and other American cities and towns. In New York, the Irish community held its own large meeting at Cooper Institute on June 21, 1887. A detailed account in the New York Times was headlined: Irelands Sad Jubilee: Celebrating in Mourning and Bitter Memories. The New York Times story described how the capacity crowd of 2,500, in a hall decorated with black crepe, listened attentively to speeches denouncing British rule in Ireland and the actions of the British government during the Great Famine of the 1840s. Queen Victoria was criticized by one speaker as Irelands tyrant.

History - Waiting for Macedonia Essay Example | Topics and Well Written Essays - 1500 words

History - Waiting for Macedonia - Essay Example Macedonian men and women don’t necessarily feel a kinship tie to their land, unlike Bosnians. Changes experienced by the young female engineers in Skopje include the fact that they feel more liberated to do as they please, and less inhibited. Young modern socialist women in Macedonia are classified on the upper level of the social strata in comparison to Albanian women of the village, who are sometimes pillaged by war, adversity, and infirmity. Unlike women in the European Union, those from Macedonia and Albania are generally regarded as lower-class – but that might be because the countries that they are from in Southeastern Europe are less highly-regarded due to their lower socioeconomic status. Another personal identity that is portrayed in the book is religion. Religion is more relegated to a status that is separated from the state in Macedonia, and people learn to get along with each other even though they are from different religious backgrounds. Religion, in the m ovie, is portrayed as a necessary part of life. In Bosnia, everyone is split up into factions. It might have had a lot to do with the fact that in the early ‘90s everyone in the region had to at least hear about, if not deal with, the Bosnian War. The Bosnian War divided people into three distinct groups: the Bosnian Muslims; the Orthodox Christian Serbians (also known as Serbs); and the Catholic Croatians (also known as Croats). The Croatians were pitted against the Bosnians by the Serbs. But basically, the Serbians were persecuting the Bosnians based on the fact that they were Muslims. President Bill Clinton finally decided to intervene in the Bosnian conflict in order to prevent an even larger genocide from taking place. To be Muslim in Bosnia meant to be the oppressed. To be a Croatian Catholic meant to be caught in the middle between a centuries-old fight between the Orthodox Christian Serbs and the Bosnian Muslims. National Identities Both the book and the film analyze d ifferent elements of national identity as well. Classifications of national identity in Yugoslavia during the existence of the country were never completely solidified because everyone came from different ethnic backgrounds. This only made allegiance to a nationality more difficult to believe in. The uncertainties of life after Yugoslavia, however, were somehow easier to deal with than the fact that much national pride was never lost on many Yugoslavians who were able to assimilate by ethnic groups. Religion can sometimes pose as nationality in the sense that, if someone is a Muslim, they might automatically assume that they are Bosnian. Thus, in a sense, in that region of the world one’s religious identity gets fused with a nationality even though that may not reflect the reality of an individual. In a similar manner – to put it in another way – many people also assume that someone whose religion is Judaism is necessarily an Israeli, but that’s not absol utely true. Nor is it true that someone who is an Israeli is necessarily Jewish –actually, it is the converse. Nothing can be assumed or presumed. While someone may be ethnically Jewish, they may not be a Jewish national (from Israel), and nothing guarantees that someone’s religion is Judaism unless proven otherwise. Therefore, nationality, ethnicity, race, and religion, for some Jewish people, are all one and the same. But certain people do differentiate between

Music - Essay Example Rock sales were relatively much higher than those of jazz. The fusion was a combination of funk, rhythm, blues that allowed the formation of a new category of music with an impact on both genres. Born at the time of the hippie movement in the late 60’s to early 70’s it expressed dissatisfaction with current (Allen, 2014). Issues such as the Vietnam War and the civil rights movement and had a wide reach. It was revolutionary and harnessed rock’s electric guitars and drum’s with Miles Davis trumpet. This was the first time jazz musicians used electric music. The impact on both genres of music was huge. Fusion combined the work of jazz greats like Miles and rock greats like The Rolling Stones. In 1968 Miles released jazz fusion first album to criticism from some of his fans. Among the reasons for criticism was that it was not a true form of jazz, it adulterated pure jazz and that money was the motivation. Older jazz generation was against it and music critic Stanley Crouch felt that it threatened jazz. Crouch says that Miles sold out for money to maintain his expensive lifestyle including drug addiction (Davis, 2014). Being a pioneer jazz had a big name in jazz music and all expectations were that he would remain true to jazz as an African-American. Critics saw this as an attempt by Miles to look for popularity at the cost of maintaining a crucial part of the African-American history. Miles had to have an extremely strong will to pursue jazz fusion as the combination of predominantly black jazz and white rock faced heavy criticism. Moreover having been a pioneer black jazz musician his reputation would be soiled as sell out for white money and bigger audiences (Goldsher, 2013). Jazz fusion has all the features of jazz including extreme improvisation and soloists with distinctive voices. Many jazz fusion musicians like Miles Davis had played the traditional jazz before venturing into the electric form. The fusion gave listeners freedom of choice and was

Freehold estates are a type of real property that an individual has the right of ownership for an indefinite period while in the case of non-freehold estates; the owner has the right of ownership for a limited period of time (Rogers 2012). Concurrent estate is property that is owned by two or more persons. Real property is immovable. Personal property is any type of property that does not fall under real property. Personal property includes any right that an individual has over movable things. Personal property can be categorized into corporeal and incorporeal forms of personal property. Personal property can be moved from one place to another. The law treats each type of property differently and so should the society. This is mainly due to the fact that the different properties have different characteristics. Businesses protect their logos through intellectual property, businesses, land and buildings are protected using the real property law and the goods that they offer to their consumers are protected by personal law. I couldn’t agree with you less. Your explanations are straight to the point and I think that giving suitable examples makes your work a masterpiece. However, I wish you would have elaborated more on how the society should treat the different types of properties. I totally agree with you when it comes to real property characteristics. However, when it comes to intellectual property I think that it is not personally owned as you have stated. That said, I think your examples on the same are correct (copyrights and patents).

Marketing in Travel and tourism - Essay Example Economic challenges also hot the company given the rate of inflation as realized in the different countries, there are also social factors that relating to population and distribution of age that also determines success of the business. In the contemporary society, technology is a very important tool in business, the company is bound to automate most of their operations to reduce overhead cost of the company incurs. There are also legal challenges that face the company since the company in other countries faces discriminative laws that give preference to the local companies. There are also environmental challenges that the company faces particularly the fact they operates airline, this includes weather and climate. Travel and Tourism Motivation Various studies have dealt with tourist motivations and market segmentation showing that the factors that motivate tourists for leisure travel and tourism can be classified into two types that is the â€Å"push† and â€Å"pull† f actors (Mehmet 2011, p.153). ... Having a good analysis of the tourist motivation extends the theoretical and empirical evidence that shows that there is a casual relationship in the push and pull factors that motivate travel and tourism, the satisfaction, and destination loyalty (Yoon and Uysal 2005, pp.45-56). Motivation refers to the psychological, biological, social needs and wants including the internal or external forces that dictate how individuals are pushed by motivation variables to make decisions to travel and how they are pulled by the attributes of a particular destination. The â€Å"push† factors refer to the intangible, intrinsic desires of an individual traveller or the tourist, for example the desire to go for an adventure, rest or relaxation while the â€Å"pull† factors define the attractiveness of a particular destination and the tangible characteristics of the place, such as accommodation and recreational facilities it offers, cultural or historical attractions. Travel and tourism motivation involves many dimensions as tourists often have more than a single motive for choosing a particular destination, which may be dynamic or flexible in nature. Understanding the factors that motivate tourists to visit a particular destination and how it differs from others who choose a different destination is important as it may help those who plan and market tourism and travel products to set the relevant marketing strategies. It is also vital as it helps destinations to build strategies for marketing and differentiating its products and services from those that are in competition with it. In analysing the factors for motivation for tourism and travel, it is important that demographical

An Inspector Calls by J.B Priestley Essay Example | Topics and Well Written Essays - 500 words

An Inspector Calls by J.B Priestley - Essay Example It also mentioned the woman who urged Eva to go to the Palace bar who was an agent of Brumley's prostitutes. More to that are the people mentioned in her lodgings. The play portrayed so many concerns that relates to how a person should act in the society that he or she lives in. One of the highlights of the play is the death of Eva which led to the most important argument in the play which is responsibility. At the beginning of the play, Mr. Birling gave his restricted view of responsibility in a extensive dialogue. Moreover, Mr. Birling's definition of responsibility was followed by the appearance of the Inspector. Then the inspector gave his concept of responsibility as well before he left. Second is the lowers costs and higher prices. It manifested the playwright's view on of Mr. Birling's enthusiasm for joining the two affluent families of Croft and Birling and his hopes that they can still work for lower costs and higher prices. As a businessman, lower costs are mostly realized by paying the workers lower wages. Third, the play opened the window about divulging the identity of the Croft and the Birling families- their likeness and their differences. It also showed how the two families present themselves in gatherings. Lastly, this play depicted a common scenario in the early 20th century.

Election 1912 Essay Example for Free

Election 1912 Essay In the election of 1912, candidates Woodrow Wilson, Theodore Roosevelt, William Taft and Eugene Debs competed for the spot as President of the United States. Wilson represented the Democratic Party, Roosevelt, the Progressive, Taft, the Republican and Debs, the Socialist. Although there were four candidates in the running, most would agree that the real competition was between Wilson and Roosevelt. A few of the many issues during the time of this election concerned trusts, women’s suffrage and tariffs. Wilson thought that trusts, or big monopolistic businesses, should be eliminated all together, while Roosevelt wanted to place limits on them. Roosevelt openly supported women’s suffrage and Wilson wanted individual states to decide voting rights for women. Wilson wanted to get rid of tariffs along with trusts, but Roosevelt wanted to keep them in order to protect wages. There was still an indecisiveness between state power and national power as we have seen in nearly every era preceding. Can’t Bring A Bull Moose Down In the first ad, the audience we were trying to address was the everyday, common men. We felt that people could relate to facing hard times and adversities and overcoming them. As common people ourselves we found these acts admirable and felt that the common man of 1912 would have viewed them the same way. This ad is supposed to show viewers about how persistence is an important quality in a president and how Roosevelt clearly showed that quality when he kept speaking for 90 minutes after being shot in the chest. This way, viewers will know that Roosevelt will be persistent in his original and elected beliefs when making decisions for their country. What Women Want The audience we were trying to address in the second ad were women. Although women did not have voting rights, they still had a fair amount of political pull. The issue of voting rights would have been a very important one to women everywhere at the time and the fact that Wilson did not even acknowledge them was an issue, whereas Roosevelt supported women’s suffrage in his campaign. The message of this ad tried to get voters to retract support for Wilson because he didn’t encourage women’s rights and support Roosevelt because he did.

Development of Sustainable LED Lighting for Offices

Development of Sustainable LED Lighting for Offices CHAPTER 1 INTRODUCTION 1.1: Study Background Climate change is rapidly increasing in our environment due to an increase in gases such as carbon dioxide and methane produced by humans and animals in the Earths atmosphere. As humans we have a moral responsibility to control and save the environment. The built environment is one of the major impacts towards greenhouse gas emissions. Designers are now pressured to design sustainable buildings that have less impact on emissions that damage the environment. The term sustainability means to save natural resources for future generations. Many buildings indirectly use resources such as fossil fuels which are converted into energy. Lighting systems in buildings consume some of this energy. Lighting accounts for around 15% of the energy bill in most homes, and around 25% in commercial buildings. It is supplied by electrical power plants using fossil fuels, and is responsible for a significant percentage of carbon dioxide emissions (Marshall 2009) To help combat how we as consumers use electric lighting an alternative can be achieved via sustainable lighting. Sustainable lighting can be defined as, Lighting that meets the qualitative needs of the visual environment with the least impact on the physical environment. (Service Lamp Corp. 2001) Light is an electromagnetic radiation, which means it is partially electric, magnetic and radiates.   Light starts off from atoms (electrons that orbit the nucleus). When energy is absorbed by an atom the electrons shift up to a bigger orbit. When the atom loses the energy the electrons shift back down to the original orbit, while the electrons shift back down they emit light in the form of electromagnetic radiation. (Sarlina 2009) This document will review material on lighting systems in the office environment. The document will start with a brief history of the light bulb and then go on to how humans interpret light. The document will discuss how LED technology would be utilised more in offices and discuss the importance of migrating to LED lighting systems in offices for a more sustainable environment. The thesis will include three known case studies on LED lighting installed in offices to gather and compare data in order to evaluate how LED lighting would suffice in real life environments. 1.2: Brief History The history of modern lighting starts off with the invention of the arc light in 1810 by Humphrey Davy. This worked by connecting a battery to a strip of charcoal using two wires. The strip of charcoal was charge with electricity and glowed. (Jacks 2003) In 1820 Warren De La Rue used a piece of platinum placed inside a tube.   A current was passed through the tube and the platinum lit well but the bulb did not go into production because platinum was very expensive. (Jacks 2003) A chemist and physicist Joseph Wilson Swan produced a workable electric light in 1860 which he patented as an incandescent light bulb with a filament made from carbonised paper within a partial vacuum. J. W. Swan improved on the invention in 1875 he changed the filament to a compressed and carbonised fibrous cotton thread filament. (Jacks 2003) An inventor called Thomas Alva Edison bought Josephs Swans patent from a company who owned the patent.   Thomas Edison worked on the light bulb to increase the life span. In 1880 Thomas Edison invented his Bamboo fibre filament lamp which lasted for 1200-1500 hours. (Jacks 2003) In 1903 Willis Whitnew invented the tungsten filament lamp (commonly used today). The tungsten lamp had a carbon filament with a metal-coating. This stopped the problem with the bulb turning dark as Thomas Edisons bulb did. (Jacks 2003) Technology today has advanced to new methods of lighting. Light emitting diode (LED) technology is now at the centre point of attention as LED lighting has many advantages with being very energy efficient, long lasting and produces less heat compared to standard incandescent or halogen bulbs. 1.3: Dissertation Structure The dissertation is divided into a sequel of five chapters. The first chapter focuses on climate change and the need to for a more sustainable built environment, a brief history into the light bulb, aims and objectives of this dissertation and the logic behind the dissertation. Chapter two is a detailed literature review which focuses on the effects of lighting on building occupants followed by government legislation, then comparing different types of lighting and leading onto research on LED technology. The information gathered is sourced from websites, government documents, books and scientific journals. Chapter three follows on from the literature review. This chapter focuses on the structure for the dissertation; firstly explaining the reason for using a literature review and then drawing on three major case studies have been chosen and all cases deal with LED lighting systems within office spaces. From the case studies the author has analysed and interpreted information.   The primary data gathered will be in the form of a qualitative questionnaire sent to lighting experts (via email) who have been involved with the case studies. The Answers have been analysed and compared to get a wide knowledge from accredited professional opinions. The fourth chapter researches into the three chosen case studies, all case studies are analysed and compared to give an overview of how effective having an LED lighting system is in an office environment. The fifth chapter discusses the results gathered from the findings. This would give an overview to the dissertation and show the key findings into answering the key questions. The final chapter will draw up conclusions as to the impact of LED lighting in office environments. The chapter addresses the original research question in the context of the findings and provides final conclusions on LED lighting and making use appropriate references where necessary. 1.4: Aim and Objectives The author has chosen sustainable LED lighting as the subject area in this dissertation. The question the author would like to propose will be: Why arent there enough office buildings using LED lighting systems? Also what effects do LED lighting have on users working in an office environment; would LEDs be beneficial for health and comfort on a psychological basis? To address the question the author will explore this main aim: The aim of this study is to research into the sustainability of LED lighting systems and how lighting can affect building users within an office environment. The author will aim analyse case studies on LED lighting systems in offices. What are the advantages and disadvantages? How would an LED lighting system be best suited for the office environment in terms of efficiency, comfort, reliability and short long term costs? The author will interview people from case studies drawn to gather primary qualitative information to reach a final conclusion. The actions the author will take to help answer the research question are listed below: Literature review, take into account of the building regulations, effects of artificial lighting on building occupants, types of artificial lighting and researching into books, case studies, reports, journals and websites related to LED lighting and other sustainable lighting systems. Research case studies on LED lighting systems that have been installed in offices. This would give the author an insight on how LED lighting systems have been successful in a real life environment. Interview researchers from case studies. Ask questions about how LEDs are designed to fit in a working office environment. Any issues that have occurred within the buildings. 1.5: Hypothesis In the United Kingdom there are very few offices if any that use an LED lighting systems to light up an office space. This could be due to lack of awareness, economic climate, social environment and lack of technology available to solve prob lematic conditions. 1.6: Key questions 1. How does light effect building users in terms of health? 2. How would LED lighting benefit offices and the environment? 3. Why isnt there many offices using LED lighting systems? 4. What is the current market like for LED lighting? Would there be a future for more LED lighting in offices? CHAPTER 2 LITERATURE REVIEW 2.1: Introduction This chapter researches into the effects of lighting on buildings occupants, legislation, different types of lighting and LED technology in detail. The aim for this literature review is to obtain information on how light is transcribed in the circadian system and the effects of light on human health. Legislation is a key issue for lighting. it regulate on the amount of light required for the appropriate tasks usually attained in different buildings, by learning legislation it would give the author an understanding into what requirements an office would need for good lighting. All information collated are from secondary and tertiary sources; for this literature review the information is found in books, journals, web pages, and government documents. 2.2: Effects of lighting on building occupants Lighting affects all building occupants on the way they perform tasks. There are different levels of lighting in different environment; the colour of light used in offices would tend to have a blue-white colour to promote concentration and light used in public areas would be a warmer yellow colour so building occupants would feel more relaxed in this type of environment. Too much light can cause health problems such as increased stress levels, headaches and higher blood pressure to the building occupant. (H.E.S.E, 2009) (Boyce, 2003 pp. 160) stated that Most apparently visual tasks have three components; visual, cognitive, and motor. Every task is unique in its balance between these components and hence in the effect lighting conditions have on task performance. (Boyce, 2003 pp. 160) also stated that Lighting conditions can affect task performance throught three systems, the visual system, the circadian system, and the perceptual system. the impact   of lighting conditions on the visual system and hence on visual performance is determined by the size, luminance contrast, and colour difference of the task and the amount, spectrum, distrbution of the lighting. The point that   (Boyce, 2003) makes is that light sent to the visual system affects the performance of the information relayed in the brain.   (Cuttle, 2008 pp. 5-6) stated The optical system of the human eye focuses an inverted image onto the retina, shown in Figure 1. This image is constantly changing with movements of the head and the scanning movements of the eyes. It is often said that the eye is like a camera, but the only similarity is that it forms a focused image in which, for every pixel, there is a corresponding element in the luminous environment. The distribution of luminance and colour that comprises the retinal image is modified by light losses that occur in the optical media of the eye, and these losses are not constant as they increase significantly with age. (Cuttle, 2008) Both books express points about how light is interpreted in the human brain differently but they both correlate how light can affect a building occupant. They both state how light is interpreted in the visual system. A research journal on Light Much More Than Vision written by Mark. S. Rea (Ph.D.) Discuses how lighting can affect the circadian system in building occupants. The journal questions if offices, school and homes are providing good lighting practises. The journal begins with an abstract on the impact of light on the circadian system The amount of light, its spectral composition, spatial distribution, timing and duration needed for vision is so different from that needed for circadian functioning, that generalizations about good lighting will have to be assessed by two very different sets of criteria in the future. (Mark. S. Rea, 2007) The journal continues on how light is interpreted in the human circadian system Light is presently and formally defined as optical radiation entering the eye that provides visual sensation. An international system of photometry has been developed and institutionalized to quantify, measure and communicate the properties of light as it affects the human vision. (Mark. S. Rea, 2007) This statement explains how light is communicated in human vision.   Practical sources of light allow humans to read material, move around spaces, drive cars, create social interaction between other users and allow user to do other activities. Under spatial distribution the journal states Through optical refraction by the cornea and lens in the eye and by neural-optical enhancements by in the retina, the spatial distribution of objects and textures in the environment can be processed by the visual system. Arguably accurate rendering of the spatial distribution of light in our environment by our retina is essential to our survival because   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   patterns of light and dark provide information needed by the visual system (Mark. S. Rea, 2007) The journal concludes with So, Are we providing healthy light in our offices, schools and homes? Probably the answer is No, we are not. Certainly we are not providing or specifiying the ideal lighting technologies and applications for the circadian regluation (Mark. S. Rea, 2007). This would bring on the question as to wether LED lighting would provide the answer to good lighting. LED has been evolving for years, they have been specifically modified to provide comfortable lighting levels for which a user could carry out certain visual functions. 2.3: Legislation The Kyoto agreement is a protocol made by the United Nations Framework Convention on Climate change. This main aim of the protocol is to stabilise greenhouse gas emissions. There are four greenhouse gases that the protocol focuses on (carbon dioxide, nitrous oxide, methane, sulphur hexafluoride). The United Kingdom Government is legally tied to the Kyoto agreement and has set out targets to meet emission rates. A document on The Kyoto Protocol by British-Energy states The UKs commitment under the protocol is for a reduction in greenhouse gas emissions of 12.5% from 1990 levels by 2008-2012. This implies an 8% reduction in CO2 emissions over this time period. The UK government also has an aspirational target for itself of a 20% reduction of CO2 emissions by 2010, demonstrating the importance of this issue for the current government.(British Energy, 2009) Offices contribute towards the CO2 emissions given off around the planet. A lot of the energy used in offices is mainly caused by office lighting. The new advancements in LED lighting could reduce the amount of energy used because LED lighting is the most sustainable type of artificial lighting. This could help aid the efforts of the Kyoto Protocol and help meets emission targets. Approved Documents Part L of the building regulations is split up into four documents. Part L1A and L1B focuses on conservation of fuel and power in domestic buildings, part L2A and L2B focuses on conservation of fuel and power in non domestic buildings. As of 6th April 2006 the revised Building Regulations Part L Conservation of Fuel and Power came into effect. The updated regulations would improve energy standards by 40 percent from that of the 2002 Building Regulations (ODPM, 2006). There are four approved documents published by the Office of the Deputy Prime Minister (ODPM, 2006): Approved Document L1A: Conservation of fuel and power (New dwellings) (2006 edition) Approved Document L1B: Conservation of fuel and power (Existing dwellings) (2006 edition) Approved Document L2A: Conservation of fuel and power (New buildings other than dwellings) (2006 edition) Approved Document L2B: Conservation of fuel and power (Existing buildings other than dwellings) (2006 edition) L1 Domestic buildings Conservation of fuel and power in dwellings. Limiting heat loss through fabric of dwelling from hot water pipes used for space heating. Limiting heat loss through hot water vessels and service pipes. Use control systems on space heating and hot water systems so that energy can be used efficiently. Use control systems on lighting systems so that energy can be used efficiently. L2 Buildings other than dwellings Conservation of fuel and power in non domestic buildings. Limiting heat loss through fabric of dwelling from hot water pipes used for space heating. Limiting heat loss through hot water vessels and service pipes. Use control systems on space heating and hot water systems so that energy can be used efficiently. Providing lighting systems with sufficient controls so that energy can be used efficiently. Limiting exposure to solar heat gains. Use control systems on air conditioning and mechanical ventilation systems so that energy can be used efficiently. Commissioning the building engineering services so that they make efficient use of energy and recording their performance. Approved Document L2A: Conservation of fuel and power highlights what is required for lighting efficiency in offices, industrial and storage areas in all building types. The document states For the purposes of this Approved Document, office areas include those spaces that involve predominantly desk-based tasks, including classrooms, seminar rooms and conference rooms, including those in schools. Reasonable provision would be to provide lighting with an average initial efficiency of not less than 45 luminaire-lumens/circuit-Watt as averaged over the whole area of these types of space in the building. (ODPM, 2006 pp. 19) LED lighting has the potential to excel past the average guide for initial efficiency of 45 lumens per watt. A breakthrough from the lighting company CREE states LED efficacy test results that set a new benchmark for the LED industry. Cree reported results of 131 lumens per watt white LED efficacy, confirmed by the National Institute of Standards and Technology in Gaithersburg, Maryland. Tests were performed using prototype white LEDs with Cree EZBrightâ„ ¢ LED chips. (CREE Inc, 2009) The CIBSE Lighting Guide 7: Office Lighting gives a guidance of how to layout lighting systems within an office to give the maximum efficiency of lighting and how much light is required for different types of office spaces. The guide states There are many ways to light an office space: with direct light down from above, from indirect light bounced from the ceiling, or from a combination of both. Many factors will dictate or influence the choice of which technique to use.   (Ruffles, 2005 pp. 7) There are many different building types and each office would need a lighting system that is individually specified. There are different types of lighting systems that give off different light intensities. The lighting guide states that a typical office space would need 500 lux (illuminance) for building users to take on paper-based or mixed tasks comfortably and 300 lux for any screen-based work. (Ruffles, 2005) Figure 2 shows the required amounts of light need for building user to work within different types of offices spaces, taken from the office lighting guide. The figures suggest that each typical office space would need 300 lux for screen based tasks, normal meetings and reception administrative tasks and 500 lux for more intense tasks such as paper-based, reading documents and writing. In a more deep-plan area the office space is required to have 500-750 lux throughout to perform multiple tasks comfortably. This is due to the fact that deep-plan areas are more towards the middle of office spaces or more than six meters away from windows; they would require a more constant flow of artificial light. This is where LED lighting may be at best because of the amount of electricity LED lighting systems take are very minimal and could deliver the required amount of light depending and the type of fixture. In normal deep-plan areas artificial lighting systems are on for longer periods because natural lighting coming in from windows would not penetrate throughout the office spaces. The corporation Philips suggests that a higher powered LED light would deliver up to 220 lumens. This type of LED would typically consume four watts. A typical deep-plan office space would require three high powered LED lights to deliver a comfortable amount of light for a user to perform various tasks, which would still consume less electricity compared to other office lighting systems. 2.4: Types of lighting There are many types of lamps that are currently used in different environments. These lamps include the incandescent lamp, compact fluorescent lamp, fluorescent lamp, halogen lamp, metal halide lamp and light emitting diodes. Incandescent lamps An incandescent lamp is a glass (See figure 3) bulb containing a thin filament. A current is passed through the filament, which heats up the filament until light is produced. (Philips, 2000 pp.49-50) stated The earliest filament lamps as developed by Swan in the United Kingdom and Edison in the United States had a short life of only 150 hours and a low efficiency of 2.5 lumens per watt, but they were thought of as a magic light source to replace gaslight. Filament lamps were clean, had greater flexibility, better colour and, with the development of available sources of power, better long-term economics. Now, a century later, the light bulb is still the preferred lamp for domestic use due to its cheap cost. Phillips (2000) continues to state that The life of a filament lamp depends upon its light output, with a greater output giving a shorter life. A life of 1000 hours with a light output of 12/14 lumens per watt was established as being a reasonable compromise and one which has stood the test of time. (Bean, 2007 pp. 139) explains that a compact fluorescent lamp is the introduction of smaller diameter tubes using high efficiency triphosphors bought with it the posibility of folding the tubes to produce compact single ended lamps. A 12W compact fluorescent lamp gives the same output as a 60W tungsten GLS lamp. Fluorescent Lamps (Fielder, 2005 pp. 28) states that Fluorescent lamps are built using a tubular glass envelope coated on the inside with a mix of phosphors. Inert Gas and a small amount of mercury is introduced into the tube to provide the atoms for photoluminescence. the tube is slightly pressurized, and the ends of the tube are capped with electrodes, which contain a cathode to generate and arc. Fluorescent lamps are 8 times more efficient than incandescent lamps and have a long life span, but fluorescent lamps contain mercury shown in figure 5. Mercury in lamps is harmful for the environment if not disposed of appropriately. Halogen Lamps The Interior Lighting for Designers book articulates that The tungsten-halogen   (or halogen)   lamp is an incandescent lamp with a selected gas of the halogen family sealed into it. As the lamp burns, the halogen gas combines with tungsten molecules that sputter off the filament and deposits the tungsten back on the filament   (Gordon, 2003 pp. 73). Figure 6 below shows an example of what a typical halogen lamp looks like. Metal Halide Lamps Metal halide lamps produce white light of a good colour quality and are available in many sizes, from compact lamps that can be used in track lighting and table lamps to huge lamps for lighting stadiums. Standard metal halide lamps tend to have a colour temperature of 3700 to 4100K and appear cool and slightly greenish. Their CRI is 65 to 70. Standard metal halide lamps typically are used where colour is not critical, such as sports arenas, parking lots, landscape lighting, and building floodlighting. (Benya, 2004 pp. 9-10) Light Emitting Diodes (LEDs) An LED is a semiconductor device that emits light when a voltage is surged through the semiconductor.   LED solid-state lighting is becoming more in use because of the energy saving benefits and long term costs. The main types of light bulbs used in offices are fluorescent lamps, incandescent tungsten filament (halogen lamps) and metal halide lamps. Fluorescent lamps are the main types of light sources used in offing lighting; the table states that the fluorescent tubes has a lamp efficiency of 32-86 Lm/W (Lumens per watt) this has a higher efficiency compared to incandescent tungsten filament lamp which have an efficiency of 7-14 Lm/W. Also fluorescent lamps can last more than ten times longer than incandescent tungsten filament lamps, but the tungsten filament lamps has a colour rendering index of 99 which means that the light intensity is much higher and would provide light that is closer to natural daylight compared to fluorescent lamps. Tungsten lamps are mainly used for executive offices to give an office a more professional looking environment. Metal halide lamps are used for desk lamp for more detailed important task where more light may be required for analytical reading and writing /complex drawing tasks. 2.5: LED technology LED technology is a fast growing lamp replacement solution in the lighting industry. LEDs contain semiconductors which are atoms of arsenic, phosphorus, germanium or other elements found in the periodic table. When electricity passes through the semiconductor visible light is emitted. Placing a number of LEDS side by side increases the increases the strength of the brightness. LED lights are also dimmable so the user could control the light intensity in a given area. The advantages of using LEDS are that they have a 50,000 to 100,000 hour life span, they consume very little electricity, they instantly light up, LED lights do not emit UV rays, they are durable to   vibrations they do not contain any mercury and LED emits light from any part of the light spectrum. The disadvantages of using LED lighting are that light is distributed directly instead of evenly compared to incandescent and fluorescent bulbs; it is very expensive to buy LED lights, they could cause light pollution in an environment because LEDs produce a lot of white light and LEDs are sensitive to heat. LED lighting is still currently being researched today to find out better methods to utilise the light from LEDs. An article from The Independent newspaper states The Indian government hopes to remedy this situation, which affects 112,000 rural villages across the country, over the next decade. The solution is a combination of light-emitting diodes (LEDs) and solar power. The former are more efficient than light bulbs the power required to light one conventional 100W bulb can now light an entire village and the latter allows electricity to be stored in batteries and provides lighting where there is no grid supply. Both LEDs and solar panels can also take the rough and tumble of village life: having few moving parts, they are very durable. (Independent, 2006) It is evident to see from this statement that the progress of utilising light from LEDs is positive; however this is not something that can be generalised to a greater population at this current time due to economics. A journal published from the Philips Research Centre shows an experiment on LED light sources and modelling for practical control systems for LEDs. (Subramanian Muthu, 2002) states The recent improvements in high-power light emitting diodes (LED) technology with 100+ lumens per LED chip and efficacy exceeding that of incandescent lamps brings the solid-state lighting close to a reality. An LED light source made of Red, Green and Blue (RGB) LEDs can provide a compact light source with unique features such as instant colour variability. In this paper, we highlight the issues that introduce the variability in the colour point and present feedback control schemes to overcome these problems. (Subramanian Muthu, 2002) The journal concluded with: RGB-LEDs have enormous potential in lighting applications. The major issue to be resolved is control and maintenance of the white point. This issue arises from the variation in LED wavelength and lumen output with temperature, drive current and time. Further complications arise due to the wide spread in the performance parameters of nominally identical LEDs. In this paper we have presented solutions to these issues using electronic feedback control of the light output of the LEDs. (Subramanian Muthu, 2002) A journal on Fundamental Analysis for Visible-Light Communication System Using LED Lights states LED is more advantageous than the existing incandescent in terms of life expectancy, high tolerance to humidity, low power consumption, and minimal heat generation lighting Our group has proposed and optical wireless communication system that employs white LEDs for indoors wireless networks (8)-(11). (Nakagawa, 2004) The journal concludes In visible-light communication system, the LED lights are distributed within a room and the irradiance of light is wide for function of lighting equipment. Therefore, the intersymbol interference depended on the data rate and the FOW of receiver.   (Nakagawa, 2004) A technical report on Energy Savings Estimates of Light Emitting Diodes in Niche Lighting Applications from the U.S. Department of energy focuses on the energy performance of LED lighting systems within different sectors such as, residential lighting, traffic lighting, retail lighting and office under shelf lighting. the document states that A type of task lighting, LED office undershelf lighting systems have been introduced on the market as replacements for T12 and T8 fluorescent products used in the commercial offices. LED office undershelf lights have the potential to save 1.37 TWh/yr if the entire market shifted to 2007 LED technology, equal to 14.8 TBtu/yr of primary energy consumption. This amounts to about 20% of the annual consumption of one large (1000 MW) electric power plant or the annual electricity consumption of one hundred thousand U.S. households.(U.S. Department of Energy, 2008 pp. 50) The report also states that fluorescent lamps, T8s, and T12s are the types of lamps that are commonly used in an office environment. These fluorescent lighting systems have a fixture efficiency of less than 40%.   This follows on to the average number of hours artificial lights operate for. Office undershelf lighting systems operate for an average of 2000 hours per year, amounting to about 5.5 hours per day or 8 hours per work day. (U.S. Department of Energy, 2008 pp. 51) This would bring on maintenance costs for the building owner due to bulb replacements. The life span of LED lighting systems is far greater than fluorescent lamps, which in turn would reduce regular maintenance. The annual energy comsuption for 53 million office undershelf lighting systems consume 3.43 TWh/yr of electricity in the U.S. At the moment LED lighting systems are still new to the market and have not penetrated the market enough to calculate the actual energy savings; however LED lighting systems have the potential to save 1.37 TWh/yr of electricity if LED lights completely replaced fluorescent lighting systems. (U.S. Department of Energy, 2008 pp. 52) (DiLouie, 2006) Points that LEDs are solid state devices that produce light by passing a current through semiconductor chips which are housed in a reflector, which is Development of Sustainable LED Lighting for Offices Development of Sustainable LED Lighting for Offices CHAPTER 1 INTRODUCTION 1.1: Study Background Climate change is rapidly increasing in our environment due to an increase in gases such as carbon dioxide and methane produced by humans and animals in the Earths atmosphere. As humans we have a moral responsibility to control and save the environment. The built environment is one of the major impacts towards greenhouse gas emissions. Designers are now pressured to design sustainable buildings that have less impact on emissions that damage the environment. The term sustainability means to save natural resources for future generations. Many buildings indirectly use resources such as fossil fuels which are converted into energy. Lighting systems in buildings consume some of this energy. Lighting accounts for around 15% of the energy bill in most homes, and around 25% in commercial buildings. It is supplied by electrical power plants using fossil fuels, and is responsible for a significant percentage of carbon dioxide emissions (Marshall 2009) To help combat how we as consumers use electric lighting an alternative can be achieved via sustainable lighting. Sustainable lighting can be defined as, Lighting that meets the qualitative needs of the visual environment with the least impact on the physical environment. (Service Lamp Corp. 2001) Light is an electromagnetic radiation, which means it is partially electric, magnetic and radiates.   Light starts off from atoms (electrons that orbit the nucleus). When energy is absorbed by an atom the electrons shift up to a bigger orbit. When the atom loses the energy the electrons shift back down to the original orbit, while the electrons shift back down they emit light in the form of electromagnetic radiation. (Sarlina 2009) This document will review material on lighting systems in the office environment. The document will start with a brief history of the light bulb and then go on to how humans interpret light. The document will discuss how LED technology would be utilised more in offices and discuss the importance of migrating to LED lighting systems in offices for a more sustainable environment. The thesis will include three known case studies on LED lighting installed in offices to gather and compare data in order to evaluate how LED lighting would suffice in real life environments. 1.2: Brief History The history of modern lighting starts off with the invention of the arc light in 1810 by Humphrey Davy. This worked by connecting a battery to a strip of charcoal using two wires. The strip of charcoal was charge with electricity and glowed. (Jacks 2003) In 1820 Warren De La Rue used a piece of platinum placed inside a tube.   A current was passed through the tube and the platinum lit well but the bulb did not go into production because platinum was very expensive. (Jacks 2003) A chemist and physicist Joseph Wilson Swan produced a workable electric light in 1860 which he patented as an incandescent light bulb with a filament made from carbonised paper within a partial vacuum. J. W. Swan improved on the invention in 1875 he changed the filament to a compressed and carbonised fibrous cotton thread filament. (Jacks 2003) An inventor called Thomas Alva Edison bought Josephs Swans patent from a company who owned the patent.   Thomas Edison worked on the light bulb to increase the life span. In 1880 Thomas Edison invented his Bamboo fibre filament lamp which lasted for 1200-1500 hours. (Jacks 2003) In 1903 Willis Whitnew invented the tungsten filament lamp (commonly used today). The tungsten lamp had a carbon filament with a metal-coating. This stopped the problem with the bulb turning dark as Thomas Edisons bulb did. (Jacks 2003) Technology today has advanced to new methods of lighting. Light emitting diode (LED) technology is now at the centre point of attention as LED lighting has many advantages with being very energy efficient, long lasting and produces less heat compared to standard incandescent or halogen bulbs. 1.3: Dissertation Structure The dissertation is divided into a sequel of five chapters. The first chapter focuses on climate change and the need to for a more sustainable built environment, a brief history into the light bulb, aims and objectives of this dissertation and the logic behind the dissertation. Chapter two is a detailed literature review which focuses on the effects of lighting on building occupants followed by government legislation, then comparing different types of lighting and leading onto research on LED technology. The information gathered is sourced from websites, government documents, books and scientific journals. Chapter three follows on from the literature review. This chapter focuses on the structure for the dissertation; firstly explaining the reason for using a literature review and then drawing on three major case studies have been chosen and all cases deal with LED lighting systems within office spaces. From the case studies the author has analysed and interpreted information.   The primary data gathered will be in the form of a qualitative questionnaire sent to lighting experts (via email) who have been involved with the case studies. The Answers have been analysed and compared to get a wide knowledge from accredited professional opinions. The fourth chapter researches into the three chosen case studies, all case studies are analysed and compared to give an overview of how effective having an LED lighting system is in an office environment. The fifth chapter discusses the results gathered from the findings. This would give an overview to the dissertation and show the key findings into answering the key questions. The final chapter will draw up conclusions as to the impact of LED lighting in office environments. The chapter addresses the original research question in the context of the findings and provides final conclusions on LED lighting and making use appropriate references where necessary. 1.4: Aim and Objectives The author has chosen sustainable LED lighting as the subject area in this dissertation. The question the author would like to propose will be: Why arent there enough office buildings using LED lighting systems? Also what effects do LED lighting have on users working in an office environment; would LEDs be beneficial for health and comfort on a psychological basis? To address the question the author will explore this main aim: The aim of this study is to research into the sustainability of LED lighting systems and how lighting can affect building users within an office environment. The author will aim analyse case studies on LED lighting systems in offices. What are the advantages and disadvantages? How would an LED lighting system be best suited for the office environment in terms of efficiency, comfort, reliability and short long term costs? The author will interview people from case studies drawn to gather primary qualitative information to reach a final conclusion. The actions the author will take to help answer the research question are listed below: Literature review, take into account of the building regulations, effects of artificial lighting on building occupants, types of artificial lighting and researching into books, case studies, reports, journals and websites related to LED lighting and other sustainable lighting systems. Research case studies on LED lighting systems that have been installed in offices. This would give the author an insight on how LED lighting systems have been successful in a real life environment. Interview researchers from case studies. Ask questions about how LEDs are designed to fit in a working office environment. Any issues that have occurred within the buildings. 1.5: Hypothesis In the United Kingdom there are very few offices if any that use an LED lighting systems to light up an office space. This could be due to lack of awareness, economic climate, social environment and lack of technology available to solve prob lematic conditions. 1.6: Key questions 1. How does light effect building users in terms of health? 2. How would LED lighting benefit offices and the environment? 3. Why isnt there many offices using LED lighting systems? 4. What is the current market like for LED lighting? Would there be a future for more LED lighting in offices? CHAPTER 2 LITERATURE REVIEW 2.1: Introduction This chapter researches into the effects of lighting on buildings occupants, legislation, different types of lighting and LED technology in detail. The aim for this literature review is to obtain information on how light is transcribed in the circadian system and the effects of light on human health. Legislation is a key issue for lighting. it regulate on the amount of light required for the appropriate tasks usually attained in different buildings, by learning legislation it would give the author an understanding into what requirements an office would need for good lighting. All information collated are from secondary and tertiary sources; for this literature review the information is found in books, journals, web pages, and government documents. 2.2: Effects of lighting on building occupants Lighting affects all building occupants on the way they perform tasks. There are different levels of lighting in different environment; the colour of light used in offices would tend to have a blue-white colour to promote concentration and light used in public areas would be a warmer yellow colour so building occupants would feel more relaxed in this type of environment. Too much light can cause health problems such as increased stress levels, headaches and higher blood pressure to the building occupant. (H.E.S.E, 2009) (Boyce, 2003 pp. 160) stated that Most apparently visual tasks have three components; visual, cognitive, and motor. Every task is unique in its balance between these components and hence in the effect lighting conditions have on task performance. (Boyce, 2003 pp. 160) also stated that Lighting conditions can affect task performance throught three systems, the visual system, the circadian system, and the perceptual system. the impact   of lighting conditions on the visual system and hence on visual performance is determined by the size, luminance contrast, and colour difference of the task and the amount, spectrum, distrbution of the lighting. The point that   (Boyce, 2003) makes is that light sent to the visual system affects the performance of the information relayed in the brain.   (Cuttle, 2008 pp. 5-6) stated The optical system of the human eye focuses an inverted image onto the retina, shown in Figure 1. This image is constantly changing with movements of the head and the scanning movements of the eyes. It is often said that the eye is like a camera, but the only similarity is that it forms a focused image in which, for every pixel, there is a corresponding element in the luminous environment. The distribution of luminance and colour that comprises the retinal image is modified by light losses that occur in the optical media of the eye, and these losses are not constant as they increase significantly with age. (Cuttle, 2008) Both books express points about how light is interpreted in the human brain differently but they both correlate how light can affect a building occupant. They both state how light is interpreted in the visual system. A research journal on Light Much More Than Vision written by Mark. S. Rea (Ph.D.) Discuses how lighting can affect the circadian system in building occupants. The journal questions if offices, school and homes are providing good lighting practises. The journal begins with an abstract on the impact of light on the circadian system The amount of light, its spectral composition, spatial distribution, timing and duration needed for vision is so different from that needed for circadian functioning, that generalizations about good lighting will have to be assessed by two very different sets of criteria in the future. (Mark. S. Rea, 2007) The journal continues on how light is interpreted in the human circadian system Light is presently and formally defined as optical radiation entering the eye that provides visual sensation. An international system of photometry has been developed and institutionalized to quantify, measure and communicate the properties of light as it affects the human vision. (Mark. S. Rea, 2007) This statement explains how light is communicated in human vision.   Practical sources of light allow humans to read material, move around spaces, drive cars, create social interaction between other users and allow user to do other activities. Under spatial distribution the journal states Through optical refraction by the cornea and lens in the eye and by neural-optical enhancements by in the retina, the spatial distribution of objects and textures in the environment can be processed by the visual system. Arguably accurate rendering of the spatial distribution of light in our environment by our retina is essential to our survival because   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   patterns of light and dark provide information needed by the visual system (Mark. S. Rea, 2007) The journal concludes with So, Are we providing healthy light in our offices, schools and homes? Probably the answer is No, we are not. Certainly we are not providing or specifiying the ideal lighting technologies and applications for the circadian regluation (Mark. S. Rea, 2007). This would bring on the question as to wether LED lighting would provide the answer to good lighting. LED has been evolving for years, they have been specifically modified to provide comfortable lighting levels for which a user could carry out certain visual functions. 2.3: Legislation The Kyoto agreement is a protocol made by the United Nations Framework Convention on Climate change. This main aim of the protocol is to stabilise greenhouse gas emissions. There are four greenhouse gases that the protocol focuses on (carbon dioxide, nitrous oxide, methane, sulphur hexafluoride). The United Kingdom Government is legally tied to the Kyoto agreement and has set out targets to meet emission rates. A document on The Kyoto Protocol by British-Energy states The UKs commitment under the protocol is for a reduction in greenhouse gas emissions of 12.5% from 1990 levels by 2008-2012. This implies an 8% reduction in CO2 emissions over this time period. The UK government also has an aspirational target for itself of a 20% reduction of CO2 emissions by 2010, demonstrating the importance of this issue for the current government.(British Energy, 2009) Offices contribute towards the CO2 emissions given off around the planet. A lot of the energy used in offices is mainly caused by office lighting. The new advancements in LED lighting could reduce the amount of energy used because LED lighting is the most sustainable type of artificial lighting. This could help aid the efforts of the Kyoto Protocol and help meets emission targets. Approved Documents Part L of the building regulations is split up into four documents. Part L1A and L1B focuses on conservation of fuel and power in domestic buildings, part L2A and L2B focuses on conservation of fuel and power in non domestic buildings. As of 6th April 2006 the revised Building Regulations Part L Conservation of Fuel and Power came into effect. The updated regulations would improve energy standards by 40 percent from that of the 2002 Building Regulations (ODPM, 2006). There are four approved documents published by the Office of the Deputy Prime Minister (ODPM, 2006): Approved Document L1A: Conservation of fuel and power (New dwellings) (2006 edition) Approved Document L1B: Conservation of fuel and power (Existing dwellings) (2006 edition) Approved Document L2A: Conservation of fuel and power (New buildings other than dwellings) (2006 edition) Approved Document L2B: Conservation of fuel and power (Existing buildings other than dwellings) (2006 edition) L1 Domestic buildings Conservation of fuel and power in dwellings. Limiting heat loss through fabric of dwelling from hot water pipes used for space heating. Limiting heat loss through hot water vessels and service pipes. Use control systems on space heating and hot water systems so that energy can be used efficiently. Use control systems on lighting systems so that energy can be used efficiently. L2 Buildings other than dwellings Conservation of fuel and power in non domestic buildings. Limiting heat loss through fabric of dwelling from hot water pipes used for space heating. Limiting heat loss through hot water vessels and service pipes. Use control systems on space heating and hot water systems so that energy can be used efficiently. Providing lighting systems with sufficient controls so that energy can be used efficiently. Limiting exposure to solar heat gains. Use control systems on air conditioning and mechanical ventilation systems so that energy can be used efficiently. Commissioning the building engineering services so that they make efficient use of energy and recording their performance. Approved Document L2A: Conservation of fuel and power highlights what is required for lighting efficiency in offices, industrial and storage areas in all building types. The document states For the purposes of this Approved Document, office areas include those spaces that involve predominantly desk-based tasks, including classrooms, seminar rooms and conference rooms, including those in schools. Reasonable provision would be to provide lighting with an average initial efficiency of not less than 45 luminaire-lumens/circuit-Watt as averaged over the whole area of these types of space in the building. (ODPM, 2006 pp. 19) LED lighting has the potential to excel past the average guide for initial efficiency of 45 lumens per watt. A breakthrough from the lighting company CREE states LED efficacy test results that set a new benchmark for the LED industry. Cree reported results of 131 lumens per watt white LED efficacy, confirmed by the National Institute of Standards and Technology in Gaithersburg, Maryland. Tests were performed using prototype white LEDs with Cree EZBrightâ„ ¢ LED chips. (CREE Inc, 2009) The CIBSE Lighting Guide 7: Office Lighting gives a guidance of how to layout lighting systems within an office to give the maximum efficiency of lighting and how much light is required for different types of office spaces. The guide states There are many ways to light an office space: with direct light down from above, from indirect light bounced from the ceiling, or from a combination of both. Many factors will dictate or influence the choice of which technique to use.   (Ruffles, 2005 pp. 7) There are many different building types and each office would need a lighting system that is individually specified. There are different types of lighting systems that give off different light intensities. The lighting guide states that a typical office space would need 500 lux (illuminance) for building users to take on paper-based or mixed tasks comfortably and 300 lux for any screen-based work. (Ruffles, 2005) Figure 2 shows the required amounts of light need for building user to work within different types of offices spaces, taken from the office lighting guide. The figures suggest that each typical office space would need 300 lux for screen based tasks, normal meetings and reception administrative tasks and 500 lux for more intense tasks such as paper-based, reading documents and writing. In a more deep-plan area the office space is required to have 500-750 lux throughout to perform multiple tasks comfortably. This is due to the fact that deep-plan areas are more towards the middle of office spaces or more than six meters away from windows; they would require a more constant flow of artificial light. This is where LED lighting may be at best because of the amount of electricity LED lighting systems take are very minimal and could deliver the required amount of light depending and the type of fixture. In normal deep-plan areas artificial lighting systems are on for longer periods because natural lighting coming in from windows would not penetrate throughout the office spaces. The corporation Philips suggests that a higher powered LED light would deliver up to 220 lumens. This type of LED would typically consume four watts. A typical deep-plan office space would require three high powered LED lights to deliver a comfortable amount of light for a user to perform various tasks, which would still consume less electricity compared to other office lighting systems. 2.4: Types of lighting There are many types of lamps that are currently used in different environments. These lamps include the incandescent lamp, compact fluorescent lamp, fluorescent lamp, halogen lamp, metal halide lamp and light emitting diodes. Incandescent lamps An incandescent lamp is a glass (See figure 3) bulb containing a thin filament. A current is passed through the filament, which heats up the filament until light is produced. (Philips, 2000 pp.49-50) stated The earliest filament lamps as developed by Swan in the United Kingdom and Edison in the United States had a short life of only 150 hours and a low efficiency of 2.5 lumens per watt, but they were thought of as a magic light source to replace gaslight. Filament lamps were clean, had greater flexibility, better colour and, with the development of available sources of power, better long-term economics. Now, a century later, the light bulb is still the preferred lamp for domestic use due to its cheap cost. Phillips (2000) continues to state that The life of a filament lamp depends upon its light output, with a greater output giving a shorter life. A life of 1000 hours with a light output of 12/14 lumens per watt was established as being a reasonable compromise and one which has stood the test of time. (Bean, 2007 pp. 139) explains that a compact fluorescent lamp is the introduction of smaller diameter tubes using high efficiency triphosphors bought with it the posibility of folding the tubes to produce compact single ended lamps. A 12W compact fluorescent lamp gives the same output as a 60W tungsten GLS lamp. Fluorescent Lamps (Fielder, 2005 pp. 28) states that Fluorescent lamps are built using a tubular glass envelope coated on the inside with a mix of phosphors. Inert Gas and a small amount of mercury is introduced into the tube to provide the atoms for photoluminescence. the tube is slightly pressurized, and the ends of the tube are capped with electrodes, which contain a cathode to generate and arc. Fluorescent lamps are 8 times more efficient than incandescent lamps and have a long life span, but fluorescent lamps contain mercury shown in figure 5. Mercury in lamps is harmful for the environment if not disposed of appropriately. Halogen Lamps The Interior Lighting for Designers book articulates that The tungsten-halogen   (or halogen)   lamp is an incandescent lamp with a selected gas of the halogen family sealed into it. As the lamp burns, the halogen gas combines with tungsten molecules that sputter off the filament and deposits the tungsten back on the filament   (Gordon, 2003 pp. 73). Figure 6 below shows an example of what a typical halogen lamp looks like. Metal Halide Lamps Metal halide lamps produce white light of a good colour quality and are available in many sizes, from compact lamps that can be used in track lighting and table lamps to huge lamps for lighting stadiums. Standard metal halide lamps tend to have a colour temperature of 3700 to 4100K and appear cool and slightly greenish. Their CRI is 65 to 70. Standard metal halide lamps typically are used where colour is not critical, such as sports arenas, parking lots, landscape lighting, and building floodlighting. (Benya, 2004 pp. 9-10) Light Emitting Diodes (LEDs) An LED is a semiconductor device that emits light when a voltage is surged through the semiconductor.   LED solid-state lighting is becoming more in use because of the energy saving benefits and long term costs. The main types of light bulbs used in offices are fluorescent lamps, incandescent tungsten filament (halogen lamps) and metal halide lamps. Fluorescent lamps are the main types of light sources used in offing lighting; the table states that the fluorescent tubes has a lamp efficiency of 32-86 Lm/W (Lumens per watt) this has a higher efficiency compared to incandescent tungsten filament lamp which have an efficiency of 7-14 Lm/W. Also fluorescent lamps can last more than ten times longer than incandescent tungsten filament lamps, but the tungsten filament lamps has a colour rendering index of 99 which means that the light intensity is much higher and would provide light that is closer to natural daylight compared to fluorescent lamps. Tungsten lamps are mainly used for executive offices to give an office a more professional looking environment. Metal halide lamps are used for desk lamp for more detailed important task where more light may be required for analytical reading and writing /complex drawing tasks. 2.5: LED technology LED technology is a fast growing lamp replacement solution in the lighting industry. LEDs contain semiconductors which are atoms of arsenic, phosphorus, germanium or other elements found in the periodic table. When electricity passes through the semiconductor visible light is emitted. Placing a number of LEDS side by side increases the increases the strength of the brightness. LED lights are also dimmable so the user could control the light intensity in a given area. The advantages of using LEDS are that they have a 50,000 to 100,000 hour life span, they consume very little electricity, they instantly light up, LED lights do not emit UV rays, they are durable to   vibrations they do not contain any mercury and LED emits light from any part of the light spectrum. The disadvantages of using LED lighting are that light is distributed directly instead of evenly compared to incandescent and fluorescent bulbs; it is very expensive to buy LED lights, they could cause light pollution in an environment because LEDs produce a lot of white light and LEDs are sensitive to heat. LED lighting is still currently being researched today to find out better methods to utilise the light from LEDs. An article from The Independent newspaper states The Indian government hopes to remedy this situation, which affects 112,000 rural villages across the country, over the next decade. The solution is a combination of light-emitting diodes (LEDs) and solar power.

LED office undershelf lights have the potential to save 1.37 TWh/yr if the entire market shifted to 2007 LED technology, equal to 14.8 TBtu/yr of primary energy consumption. This amounts to about 20% of the annual consumption of one large (1000 MW) electric power plant or the annual electricity consumption of one hundred thousand U.S. households.(U.S. Department of Energy, 2008 pp. 50) The report also states that fluorescent lamps, T8s, and T12s are the types of lamps that are commonly used in an office environment. These fluorescent lighting systems have a fixture efficiency of less than 40%.   This follows on to the average number of hours artificial lights operate for. Office undershelf lighting systems operate for an average of 2000 hours per year, amounting to about 5.5 hours per day or 8 hours per work day. (U.S. Department of Energy, 2008 pp. 51) This would bring on maintenance costs for the building owner due to bulb replacements. The life span of LED lighting systems is far greater than fluorescent lamps, which in turn would reduce regular maintenance. The annual energy comsuption for 53 million office undershelf lighting systems consume 3.43 TWh/yr of electricity in the U.S. At the moment LED lighting systems are still new to the market and have not penetrated the market enough to calculate the actual energy savings; however LED lighting systems have the potential to save 1.37 TWh/yr of electricity if LED lights completely replaced fluorescent lighting systems. (U.S. Department of Energy, 2008 pp. 52) (DiLouie, 2006) Points that LEDs are solid state devices that produce light by passing a current through semiconductor chips which are housed in a reflector, which is
