Finally, the boy was capable of completely control his anger and temper. He informed his father concerning the new situation of experiencing no anger. The father ten directed the boy to remove the each nail, for the days he was incapable of managing his anger. The weeks passed, and finally the boy informed his father that all the nails have been removed from the wooden fence. The father led his son by hand and led him to the wooden fence. He instructed his son to observe the holes left in the fence. The holes distorted the surface of the fence. In a similar situation, anger distorts and leaves a noticeable scar. The father informed the son that if he strikes somebody with a knife and immediately removes it; the wound will forever be there, despite numerous apologies to the victim.

Comics are considered as a Low culture and comics and graphic novel are similar to each other but graphic novel are not considered to be Low culture. High culture text is written to encourage complex reflection and thought. High culture are usually full of literary features while low culture has low literary features. Text with high culture also called privileged text and text with low culture is called marginalized . 2- Everyone has his own way of thinking, if three people read a book they will think differently and will have different opinions about it that’s why we respond to the text is shaped by our ideology because everyone understand it from a different perspective. The same thing happens when different people read a graphic novel , they all have different opinions and ideas and they discuss it some people may change their opinions after they heard someone’s else opinion ,that’s how it changes our beliefs, attitudes and values toward literature 3- Symbols in a Graphic novel are easy to understand cause most of the are colours , body language , objects and clothing etc.. .In Persepolis Satrapi has made it different than any other graphic novels , she made no colours only black and white and this is a symbol of something that happened in the past . 4- Satrapi choose to write Persepolis in form of a graphic novel to tell her story ,because she want us to understand what she understands .She is writing her story so she wants us to feel how it feels to grow up during a revolution and a war , and how it feels to move from your country to a different one having a new life she wants us to feel what she felt and she actually succeeded at it Style and Literary Traditions: Persepolis is more bildungsroman than a memoir, because Satrapi didn’t only want to tell the story of her childhood but she wanted to show the way she lived in Iran at the time of the Islamic revolution, also she wanted to show how she grew morally, socially and spiritually making herself an example of how a young girls grew up at this time and bildungsroman is when protagonist must progress from childhood to adulthood, leave home to undergo a journey, and develop a more mature understanding of his or her self. Satrapi also shows how is feels for a young girl to grow up during a Revolution and live in Iran while it was at war with Iraq, those young girls saw communists getting shot and killed by the shah army and hearing stories about political prisoners being tortured during the revolution and saw planes blowing up buildings and other events too. Although it was horrible but Satrapi use a satirical tone sometimes when talking to the revolution guardians Literary Features: Satrapi has been able to manipulate the literary features well though it is a graphic novel which sometimes authors find it hard to use the literary features. Satrapi has used alot of symbols and one of the most important symbol was â€Å" the veil â€Å" which shows the rebellious side of Satrapi and that she was against wearing it but the Islamic government said it is obligatory for women and girls to wear veil. She has also been hyperbole about it Satrapi has used many allusions; most of them are people some are rebellious figures like : Che Guevara, Fidel Castro , they symbolize how a young generation is forced to become revolutionary even though they know little about the turmoil they fight , most of the allusion are about being rebellion and the war. Unlike other writers, Marjane Satrapi has it a little easier because she is able to literally show us what she wants us to see , and the Major thing about persepolis is that it has no colours it’s all black and white to give the story a more ancient feel, she wants us to see that all of this has already occurred. Moreover, the simplicity of her images allows her to demonstrate that this time in her life was not a great one, and that most of it is blurry. Perhaps the lack of color also signifies how somber that time was. Furthermore, she usually draws herself in the background, this shows how inferior she unworthy of being at the same level of men. As she gets older in the novel, she starts to show herself more, it is almost as if she is starting to believe that she is finally getting to the level of men. She begins to talk more to people, and not only speaks her thoughts to herself. Themes: Any young woman growing up is going to face struggles especially during her adolescence. However, to grow up in the midst of the Iranian revolution is undoubtedly a life changing experience. In a society where one certain religion is forced upon you, and where you go, what you wear, who you see, and all that you do is restricted, it is clearly difficult to accept. Especially to a determined and independent young lady such as Marjane Satrapi. In Persepolis one of the most important themes of the novel is government and society and its role in determining the sequence of events that Satrapis life takes on such as in the first chapter veils are forced on the women of Iran. In Persepolis Satrapi has used many themes and as mentioned one of the most important themes is government and society. The Iranian society after the revolution was forced to do what their government tells them like wearing the veil and this is also connected to the theocracy and dictatorship theme that the Islamic government turned into a dictatorship , dictatorship was not only with the government but also in Satrapi’s house she calls her mother a â€Å" the dictator guardian of the revolution of the house The government played a big role in 1980’s Iran by implementing new laws and restricting old freedoms, whoever does obey is either sent to jail and tortured or being executed and a lot of people where being executed for doing things forbidden by Islam ,the government used Islam as a cover to do whatever they want without people questioning them. Even though the Islamic government prevented partying and drinking, people went to illegal parties and drank wine this is considered as an act of rebellion which is also a theme. Rebellion is also a major theme in Persepolis, rebellion is not only against a government it can also be rebellion to what people say. Satrapi uses cigarettes as a symbol of rebellion, she want to show that she can do whatever men can do because at this time in Iran there were feminism. Moreover , Satrapi uses more rebellion figures to support her rebellion theme like Che Guevara, Fidel Castro and Trotsky they are a symbol for freedom Iran was in an outer war with Iraq and internal war against Iranians. Those are the best words that could describe what is happening inside Iran in that time, the army was fight the Iraq’s and was also killing communists and people that have a secular thoughts. Although, the kids of the lower class are sent to war to fight for their country, but before they are sent, they are given this golden key which sybolizes the riches and wealth they will have if they go into war for their country. Not having much, these kids end up joining the army being promised these dreams that never happen. While on the other hand the higher classes are partying and enjoying themselves, not doing anything to protect their country, but only themselves. Isnt that sad. Also in the case of Marjane her maid doesnt sit with her and her parents had a cadillac showing that they were wealthy, but Marjane didn like the idea of that. If you are a powerful person that has a lot of money, or if you were a king, you were part of the high class people. If you are poor or a peasant, you are considered to be in the lower class. What also exists is a middle class who refers to those who can make enough money to dress properly and own certain things that peasants can’t. Being a part of the middle class doesn’t make you a high class person because you don’t have power and don’t have a fortune, but it’s enough for good living Martyrdom was also a major theme in Persepolis since the war started and Satrapi describes it â€Å"To die a martyr is to inject blood into the veins of society.† Marjane reflects that the regime depends on the war to retain its political control of the country. A million people lose their lives in the war. The regime becomes more repressive and seeks to stop â€Å"the enemy within† by arresting and executing those that defy its rule. Heroism is also a theme which is connected to Persepolis where Satrapi symbolizes the political prisoners that were tortured and executed as heroes and when she found out that her uncle Anoosh was tortured too ,she thought of him as a hero At this time in Iran the social classes was also a major theme in the novel mostly all social classes were unequal and this wasnt fair to Marjane at some points. She comes to learn that if you are not in the same social class as someone else, you are not able to marry them. Also, higher social classes were treated better and were paid more attention to, other than the lower class people. There was a specific part of the book where some kids asked Marjane if she had any star wars toys, and she didnt. All little Marjane had were some boring books to offer them. Persepolis is very powerful and informative. It showed the history of Iran’s civil war and revolution and the fall of the Shah. When someone would say the word Iran people would think of oil, criminals, and communist. they never knew that they would be able to relate Iran to family, love, peace, hope, Michael Jackson. It has definitely given a new meaning behind the word Iran. It has also given a new outlook of the people of Iran.

David Hicks Speech :: essays research papers

  Ã‚  Ã‚  Ã‚  Ã‚  David Hicks was a 34 year old black male. He was on death row in Texas from December of 1987 to April of 1988, sentenced to die by lethal injection for rape and murder, on April 25th 1988, of his 87-year-old grandmother, Ms. Ocolor Heggar. David was only a suspect because he was near her house at the time of the crime. There was no indication that he had been inside ¡Xexcept, for DNA evidence. The DNA test determined that similarities between sections of DNA removed from David ¡Ã‚ ¦s blood and DNA recovered from semen in Ms. Heggar ¡Ã‚ ¦s house would occur only one time in a total of 96 million people.   Ã‚  Ã‚  Ã‚  Ã‚  On the evening of Ms. Heggar ¡Ã‚ ¦s death she was alone in her house. Eddie Ray Branch, her grandson, testified that he visited his grandmother on the day that she was killed. He was there till at least 6:30 p.m. Lester Busby, her grandnephew, and David Hicks arrived while her grandson was still there and they saw him leave. They then went in to visit with Ms. Heggar. While they were there, Lester repaid Ms. Heggar 80 dollars, which he owed her. They left around 7:15 p.m. and went next door to a neighboring friend ¡Ã‚ ¦s house. David Hick ¡Ã‚ ¦s went home alone from there to get something but returned within ten minutes of leaving. Because he was only gone for 5-10 minutes, prosecution theorized TWO attacks on Ms. Heggar because he could not have killed his grandmother during this 5-10 minute period alone. At 7:30 p.m., 15 minutes after the two had left, an insurance salesman called to see Ms. Heggar. He knocked for about 2 or 3 minutes and got no reply. Her door was open but the screen door was closed. Her TV was on. He claimed to have left after about 5 minutes and then he returned the next morning. The circumstances were exactly the same. With concern, he went to the neighbor ¡Ã‚ ¦s house and called the police. His reasoning for being there was because the grandmother ¡Ã‚ ¦s family had taken out burial insurance three days before she had died. David had strong ties and a compact relationship with his immediate family. During the course of the trial, the evidence was presented which seems to clear him: „h Several hairs were recovered from the victim; tests revealed that they were not from David Hicks. One was found to be consistent with Asian hair, another consistent with Lester Busby, the grandnephew.

Manage Your Cash Flow after You Buy a Website :: Sell Websites Buy Web Sites

Manage Your Cash Flow after You Buy a Website Reprinted with permission of VotanWeb.com There is no magic formula to determine the necessary working capital for a website. Sure, every accounting-textbook provides a definition of working capital, but how does this translate into the virtual world? The bottom line is, working capital is the cash that you need to continue operating your website when your current expenses exceed the cash flowing in from Paypal or the credit card companies. Working capital is critical to the survival of your website. Sadly, for most website entrepreneurs, it tends to take a back burner until it begins to cripple their website. Website owners contact me weekly requesting a simple formula to determine working capital. Unfortunately, working-capital requirements are different for every website. In an attempt to provide some help to website owners, I offer the following observations. Websites with a fast inventory turnover don't have huge working-capital requirements because the cash flows in from Paypal or other sources 24/7. This type of website might require 10% to 15% of its annual sales as working capital, as a rule of thumb. Websites that sell a large variety of items require a larger working-capital cushion. A website that must maintain a large inventory, for instance, incurs high costs upfront for materials, but has to have the means to keep the servers up and running until it receives payment form the customers. It might be reasonable for a website such as this to keep at least 25% of annual sales as working capital, speaking generally. The better a website owner manages working capital, the less he needs to borrow and depend upon lenders. There are many examples of websites that did not manage their working capital. I know of one website that was booming and the owner had money in the bank. But it wasn't enough. The owner had decided to dramatically expand the services he offered through his website. The development of the much larger website was substantial. Meanwhile, there was the weekly payroll to cover, the monthly rent for the servers and other expenses. Moreover, as is typical with any website expansion, it takes some time for customers to learn that you are offering additional services. This means that there is some delay between spending the money for the expansion and receiving the money from the increased sales activities. On theory, the website was doing great.

Alcohol Abuse Among Teenagers Essay

It’s very interesting that I find myself writing about something that not only is commonsense, but what is more, something that every one knows about in general but may not in particular. Alcohol use among teenagers is a serious problem and is responsible for death and injury in automobile accidents, physical and emotional disability, deterioration of academic performances, aggressive behavior that causes a number of other sociological problems in families and among friends. It is also the primary cause of criminal behavior and a leading cause of broken marriages. As we know it’s a broad topic therefore I’ll look at the role that alcohol plays in the society and it’s impact on teenage addiction. MATTER OF CONCERN (Causes and effects) The age when young people are taking their first drink is becoming lower each year. Many studies show that preteens are experimenting with alcohol and many are already heavy drinkers (Cahalan 1997). It may be difficult for parents and teachers to believe that a seventh grade student can have an alcohol problem, but a study of student drinking practices shows that 5% of seventh-grade boys and 4. 4% of seventh-grade girls are seriously abusing alcohol (Royce 1996). That’s why we see the consequences in terms of antisocial behavior, school failure, attention deficit, learning disabilities and road accidents among the teenagers. THE MAIN CAUSE ?.. MEDIA. Despite the problems caused to young and old by alcohol, society sends mixed signals to its youth. Media presents alcohol drinking with peers as not only acceptable but also to insure friendship and as a romantic beverage. Movies present a realistic picture of alcohol abuse. A report by â€Å"scientific analysis corporation† examined drinking practices on television and found that out of 225 programs 701 alcoholic drinking acts were recorded which were against the voluntary code (Jean Lennane,1995) of the liquor industry. The code states that: a) Any actor shown drinking must be over the age sixty. a) Any drinking shown should be natural, sensible and responsible. a) Ads should not suggest that drinking alcohol contributes toward social, sexual or supporting success or as being a pre-requisite of relaxation. a) Ads should not challenge or dare people to consume alcohol. We can see the ads any night and judge rather how many don’t breach the voluntary code. AVAIBILITY AND ACCEPTABILITY A leading cause is that alcoholic drinks can be easily obtained and these are socially more acceptable than other drugs. Parents, teenagers and educators often fail to realize the potential for problems that alcohol presents to the immature psyche and body(Kay Healey, 1997). At the time when body and emotions are maturing, frequent or excessive use of alcohol can cause irrapareable damage. MISCONCEPTION: Drinking alcohol is only viewed as an adult behavior in the society. Alcoholic beverages are advertised and marketed as being associated with sexuality and romance, but, infact alcohol is a depressant which decreases overall sexual performance and dulls pleasurable feelings. (Kay Healey,1997) FAMILY FACTORS: Parental attitude and behavior regarding alcohol use play important role in how their children view it’s use. Evidence exists that a family history of antisocial and poor parenting increases the risk of having children who use alcohol and other drugs. The home is the primary source of alcohol for the young adolescent. ADOLESCENT DEVELOPMENT: Teenagers report that they drink for enjoyment, to forget problems or to reduce stress and anxiety in their lives. Teenagers, however are at increased risk of becoming intoxicated while drinking less than adults because of their limited experience with alcohol and smaller body size. Depressed or those teenagers who have been physically or sexually abused may use alcohol in an attempt to cope with their psychological distress DRUNK DRIVING Inexperienced driving combined with inexperienced drinking is a deadly combination . A report from â€Å"National Centre For Health Statistics† shows that motor vehicle accidents are the leading cause of death among persons Between 15-23 years of age. Although they may reserve the right to drive, but, of course no right to put the others in danger while accidents. OTHER EFFECTS: Underage drinking has countless effects and therefore, it’s impossible to take all of them into account. Research shows that of those who began drinking at the age of 18,66% subsequently are classified with alcohol dependence and 7. 8% with alcohol abuse. If a person waits until the age of 21 before taking their first drink, these risks decreases by 60%. (Grant 103) Alcohol use can affect teenagers health, family relationships and can also place other members of the society in danger. It has a tendency to lower the productivity and the quality of work being done and can cause problems in both one’s school and career. Economic costs are also an issue when it comes to underage drinking. IDENTIFYING THE PROBLEM: Identifying the teenager alcohol abuser is difficult but not impossible. Specific behavior and characteristics to watch for to determine if alcohol abuse is occurring include the following; a) frequent absenteeism. b) decline in academic performance. c) lack of interest in extracurricular activities d) problems with peers e) self destructive behavior f) lack of energy g) lack of concern about personal wellbeing. h) obvious signs of intoxication CONCLUSION: Alcohol abuse among teenagers and even younger children is a rapidly growing social problem. Alcohol is glamorized in movies and television. Beer commercials using sports figures try to convince teenagers. As a society we send mixed signals to our youth about alcohol use, on the one hand we talk about it, joke about it, and treat it as not only acceptable but also desirable. On the other hand we recognize the problems caused by alcohol abuse. Death and injuries in traffic accidents, loss of productivity, child abuse, broken homes and other serious societal problems linked to alcohol. REMEDY: In my suggestion, an intensive education program supported by the community with qualified persons and also supported by the government in terms of financial support can positively change the attitudes and cause significant change in knowledge about alcohol. Schools can play an important role to initiate education and preventive efforts because they reach more students than any other place. It also involves complete commitment with extensive planning.

Social and Ethical Dimensions of Information and communication Research Paper

Social and Ethical Dimensions of Information and communication Technology - Research Paper Example This in turn has lead to job displacements in huge numbers. The use of information communication technology requires less deployment of man power which in turn has forced some companies to reduce their workforce, while others giving their employees more roles than required with fewer benefits which lead to increased work pressure. In a business environment, security is a serious issue of consideration as a result of increased cases of theft and related vices. In effort to curbing the challenge of insecurity, surveillance cameras developed with proper databases are installed to monitor and survey the environment and activities through this technology. In many nations, Closed Camera Televisions are commonly used in crimes department to deal with crime cases. Besides having high security benefits, introduction of CCTV has nevertheless resulted to infringement of privacy and freedoms of various individuals within the area under surveillance. This is because privacy is an important aspect and a fundamental human right. The dilemma in this case here is that, the introduction of Closed Circuit Television (CCTV) has enhanced security and the expense of individuals’ freedom and privacy. Consequently, the installation of CCTV in public places has deteriorated human privacy and freedom. Reviewing J.S. Mill’s perspective of utilitarianism, the importance of the introduction and use of CCTV is judged by its effects2. The numerous positive consequences that have come along with the introduction of CCTV in the society, it is well seen that CCTV has highly assisted in curbing crimes hence many private companies view the use of CCTV surveillance as a good idea judged by the fact of its practical benefits. As a result, it is arguable that CCTV is helping should remain in place for its benefits. Secondly, comparing the issue of high security to deteriorated privacy, CCTV’s advantages outweigh the disadvantages. The challenge is whether CCTV should remain in position

Homeland security - Assignment Example It is also true that second responder in an emergency situation, provide support roles to the first responder, who are usually the; fire response team, police among others. Their duties basically involve preparation, organization as well as offering returning services. However, it is imperative to note that the emergency second responders do not have to necessarily work behind the scenes as indicated in this post. They can also work on site in undertaking duties such as cleaning and return services (Jackson & Faith, 2012). This post indicates that significant training efforts and investment have been made in preparation and training of emergency response teams since the 2001 terrorist attack. This statement is somehow invalid; this is because, significant investment and training have been made in emergency response teams even before September 11, 2001. It could have been made better by indicating the significant improvement in relation to training and investment in emergency response teams have been made since September 2001. In relation to improving the capacities of the second responders towards provision of emergency rescue services, the statement does not indicate the fact that provision a comprehensive training for second responders could be improve their performance especially when there is a shortage of the first responders. That is, second responders should also be subjected to training involving learning the duties of first responders as well as the duties of the second responders could improve their capacity of performance when providing emergency services. It is not wise to assert that the services offered by second responders could be improved by introducing responder three; this actions would simply involve investment if huge amounts of financial resources. Instead, stakeholders can focus on research with an intention of determining more effective ways of improving the performance of the second

This enables bridging the gap between incomes and spending organized locally (Wildasin, 123). When budgets are supposed to be balanced, various constraints might result in subnational spending. According to Wildasin (125), the first constraint is the capacity of income rising of these subnational governments becomes limited. The second limitation is the occurrence of horizontal and vertical income sharing. Tax effectiveness grounds determine the optimal size of these subnational governments. The conformations of subnational incomes play a vital role in determining autonomy level over the expenditure management that the subnational governments enjoy. For example, mobilization of the local revenue is enhanced when essential tax bases are controlled by the subnational governments. This enables these governments to take legitimacy over using these resources and managing them to their needs and preferences (Wildasin, 126). Subnational governments are expected to reduce their spending management autonomy when there is reliance on revenue sharing, used in financing subnational spending that can be vertical or horizontal. In addition, fiscal decentralization may be more than delegation (Wildasin, 128). Additionally, subnational governments turn out to be spending agents of higher government levels that have inadequate decision making autonomy over the ways public funds are used up. The advantage of distribution in expenditure management is increased accountability and transparency in service delivery. This is by bringing the spending done by the public sector nearer the taxpayers. Wildasin (130) states that policy making autonomy over shared incomes enables

READING REFLECTION - DESIRING GOD by John Piper - TURABIAN FORMAT Essay

READING REFLECTION - DESIRING GOD by John Piper - TURABIAN FORMAT - Essay Example He supports his arguments by citing Judas Iscariot’s betrayal of Jesus Christ, which was a sin to fulfill God’s plan and will. Piper states that God’s pursuit of pleasure from us and our pursuit of pleasure from him are the same things.2 The main purpose of conversion is to select the few that will enter the Kingdom of heaven. Not all people who talk of God will enter the Kingdom, but only those who turn away from sin, repent and trust in God. From his book, Piper likens worship to a feast of Christian hedonism. He states that from biblical interpretations, worship includes outward acts including praying, preaching, cleansing, reciting, ordaining, lifting hands, bowing, and performing rites of eating.3 In addition, true worship must include inward feelings and thoughts that reflect on God’s worth and glory. Piper continues by stating that love is the overflow of joy in God. Love is reflected from outward acts and activities performed by people. God is love, and He loves a cheerful giver. Piper continues to state that what a person feels about money can either destroy or build one. What one does with his money forms a foundation that can build his happiness or ruin him forever. In marriage, husbands are told to love their wives because their wife’s body is theirs. They are required to do so just like Jesus died for the church. Christians are expected to continue with Paul’s missions of preaching the gospel. They are supposed to preach it in new regions and territories and to people who have not yet received it. In going out to missions, Christians are supposed to expect suffering, but put it in their hearts and minds that all their suffering is for Christ and with Christ. As such, they are not supposed to despair, but put in more efforts until they achieve their goals. The primary thesis of the book, which is Christian hedonism, relates to both private and public worship in many ways. This is mainly

Similarities and differences between monopolies and oligopolies Essay Example for Free

Similarities and differences between monopolies and oligopolies Essay According to Mankiw, N. G. (2004) monopolies and oligopolies can be defined as: Monopolies are based on a market where there are several buyers but only one seller of a product or service whereby the seller sets the price for products and services provided. Oligopolies are based on a market where there a few companies own or control the production of a product or service whereby the few companies control the market of products and services provided. Differences: Monopolies have only one seller. Oligopolies have at least two or more sellers. Monopolies offer only one product or service. Oligopolies offer more than one good or service. In monopolies the seller can set the price without competition. In oligopolies the sellers set prices based on competitor prices. Monopolies usually exceed marginal profits. Oligopolies usually meet marginal profits. Monopolies are unable to achieve any level of profit they want due to high prices that reduce consumer purchases. Oligopolies have a better chance of achieving the level of profit desired because prices are lowered to raise consumer purchases. Monopolies usually have no close substitute for products or services offered. Oligopolies usually have a small number of close substitutes for products or services offered. Similarities: Both monopolies and oligopolies consist of large organizations Both monopolies and oligopolies hold considerable market control over specific products and services. Both monopolies and oligopolies hold specific copyrights for products and services provided. Both monopolies and oligopolies are affected by increased production in the fact that higher production reduces the price of products and services. Both monopolies and oligopolies are able to achieve a monopoly on production id specific products or services under copyright. Both monopolies and oligopolies impact the production and sale of products and services. HOW WOULD YOU CLASSIFY MICROSOFTÂ ©? I would consider Microsoft to be an oligopoly company because there are several other companies that offer similar products. However, given that Microsoft holds copyrights to specific software such as Microsoft word, Microsoft Visio, and so forth O do believe that they are moving closet to becoming a monopoly company. HOW WOULD YOU CLASSIFY THE POWER INDUSTRY IN YOUR AREA? EXPLAIN YOUR REASONING. My first thought was that the power company in my area (Hampton, Virginia) would be a monopoly. However, after some research I believe that the power industry in Hampton, Virginia would be considered an oligopoly because there are several different companies offering the same services. According to Google (n. d. ) some examples of local companies offering similar services include but are not limited to: Dominion Virginia Power www. dom. com Jacqui Electric Company www. jacquie. com. au Bay Electric Co.

Application of Thermal Insulation

Application of Thermal Insulation 1.2 Problem Statement Energy saving in buildings has become a question of crucial importance in many countries. At the same time, the requirements for satisfactory indoor climate with low electricity consumption have increased which prompt the supply and demand for energy efficient homes. The battle against global warming shall start from home insulation to reduce green house gas emission. In developed countries, government has even allowed tax credit to house owners for costs incurred in carrying out home insulation works which meets the urgent need in the fight against global warming. In Malaysia, the common answer from the public in general to make a house or office cool is probably by switching on the air conditioning. The roof of most houses is constructed using timber roof trusses and concrete roof tiles in Malaysia. The heat gained through the roof which convents through the ceiling has increased the indoor heat to a level that most house owners will not feel comfortable without the use of air cond itioners. The impact that roofs have on energy is often overlooked, the impact of which can be significant. In homes, air conditioners make up 23% of energy consumption. Alternatively we can achieve the dream cool and comfort living or working environment despite in a very hot sunny day with the help of install the thermal insulation then will reduce the dependence on air conditioners to cool the home or office. This means insulating a home could potentially save thousands of ringgit in electricity bills. Install the thermal insulation in the wall or roof will increasing the cost of the building but the price tag on insulation is considered small when compared with the benefits including monthly savings in electricity bills throughout the lifespan of the house, reduced greenhouse gas emissions, improved comfort and living standards and a huge contribution to the local economic growth, as the insulation material is manufactured locally. 1.3 Aim The researchers aim for conducting this research is to review the uses and identify the importance of thermal insulation. Besides that, to find out whether application of thermal insulation to the buildings is suitable to be adopted into construction industry in Malaysia. 1.4 Objectives To review the concepts and uses of thermal insulation. To assess the importance or advantages of thermal insulation in Malaysia. To investigate the applicability of thermal insulation amongst the buildings in Malaysia. 1.5 Hypothesis Application of thermal insulation into the buildings would increase the energy saving in buildings and decrease in emission to environmental. 1.6 Background Governments all over the world are beginning to realize the importance of reducing dependence on energy imports as fuel reserves becomes scarcer and supplies are concentrated on a few politically unstable countries. The building sector is probably the most effective and easiest way to start reducing energy consumption. Reduction in energy demand can be most effective due to applying thermal insulation to the buildings. Thermal insulation is the method of preventing heat from escaping a container or from entering the container. In other words, thermal insulation can keep an enclosed area such as a building warm, or it can keep the inside of a container cold. Depending on the climate, we spend more or less energy on heating or cooling, but we will spend more energy on cooling the room by switch on the air conditioning in Malaysia. There have a main reason for using thermal insulation for reduction of heat coming in, without too much loss of light due to the hot climate in Malaysia. So, the demand of energy can be significantly reduced by install a thermal insulation into the wall or roof of those buildings. Thermal insulation has been introduced to reduce the demand of energy result in electric consumption costs up to 40% and the countrys energy resources. This allows savings on the cost of the air-conditioning, because a smaller unit is needed, and on the running cost of the air conditioning. It also indeed creates a more comfortable living and working atmosphere. Besides that, most of the people will switch on the air conditioning to keep the comfort in the room or working place in Malaysia. But, the air conditioners will release a haloalkanes which are a group of chemical compounds, consisting of chlorine, fluorine and carbon, called Chlorofluorocarbons (CFC). The CFC will among the greenhouse gases in the atmosphere that contribute to future global warming. So, apply thermal insulation to the buildings will reduce using the air conditioning naturally will reduce the emission to the environmental also. 1.7 Scope of Study The research project has provided the idea and functions of thermal insulation to the buildings make a preliminary of understanding to it. Besides that, the advantages or importances that apply the thermal insulation to the buildings in Malaysia also fall within the scopes of this research project. In this study, I have studied into few buildings in Malaysia which have installed the thermal insulation such as Pusat Tenaga Malaysia Zero Energy Office (ZEO) building at Bandar Baru Bangi and Low Energy Office (LEO) Ministry of Energy, Water and Communications Malaysia at Putrajaya. Based on these buildings, I will study the benefits that obtain from the buildings which have applied thermal insulation to the wall and roof in this research project. In addition, I will inquire into the applicability of thermal insulation in the buildings in Malaysia. 1.8 Research Methodology For the primary source, questionnaires were prepared as a ground for the main survey which relates to the reason of construction firms attempt to apply thermal insulation to the buildings in Malaysia. The questionnaires were then distributed to the construction firms which are be responsible for ‘Pusat Tenaga Malaysia Zero Energy Office (ZEO) building project and ‘Low Energy Office (LEO) Ministry of Energy, Water and Communications Malaysia through e-mail. For this purpose of survey, mailing list was obtained for website which has listing the name, address and the title of principal officer for each firm listed. That company was chosen and sent a set of questionnaire while those company which have not related into the projects will be randomly chosen for obtain the opinion on the applicability of apply thermal insulation in the buildings in Malaysia. For secondary sources, a comprehensive review of the relevant literature including a computer assisted search, textbook, journals, articles and so on, will be taken to develop an understanding of concept and uses of thermal insulation. Besides that, the importance or advantages of thermal insulation in Malaysia also will be assessed by computer assisted search. 1.9 Proposed structure of the dissertation Chapter 1: Introduction. Chapter 2: Literature Review 2.1 Review concept and uses of thermal insulation. 2.2 Review importance to apply thermal insulation into a building. 2.3 Investigation of applicability of thermal insulation into the buildings in Malaysia.

Available on: www.mimg.org.my/images/pdf/MIMG_Why_Insulate.pdf 2.0 Literature Review 2.1 Review the concepts and uses of thermal insulation 2.1.1 – Concept of thermal insulation Thermal insulation has been defined as a material or combination of materials which slow down the flow of heat, reduce some sound transmission or slow down the spread of fire when buildings are in fire.(Anish, 2003) The thermal insulation materials can be suited to any size, shape or surface and the variety of finishes to be used in order to protect the thermal insulation from mechanical and environmental damage as well as to enhance appearance of buildings.(Anish, 2003) Thermal insulation can be mentioned either to materials used to lower the rate of heat transfer, or the means and processes used to lower heat transfer. Thermal insulation will transfer heat energy and the hHYPERLINK http://en.wikipedia.org/wiki/Heateat energy would be transferred by three methods, which are convection, conduction and radiation. 2.1.1.1 Convection When the heat is flow whether by forced or natural, within a fluid and the fluid is a substance that may be either a gas or a liquid, this process is called convection.(Zhang, et al. 2005) Convection will then gravitationally-induced heat transport, driven by the expansion of a fluid on heating then hot expanded fluid has lower density, so will rise to the top of colder, and therefore denser, fluid.(Fowler, 2008) For example, when air to be heated, then it will expands and rise. However, if the air movement is established mechanically by a floor register, fan, or wind, then it will be called as a forced convection. 2.1.1.2 Conduction Conduction is direct heat flow or conducted from a material especially a solid.(Zhang, et al. 2005) When different parts of an isolated solid are at different temperatures, the heat will flow from the hot places to the cold places until eventually all is at the same temperature.(Fowler, 2008) Conduction and convection have same uses which are functions of the roughness of surfaces, air movement and the temperature difference between the air and surface. The increasing of heat energy can flow through materials and from one material to another.(Kurtus, 2006) 2.1.1.3 Radiation Radiation is the transmission of energy through space by means of electromagnetic waves.(Zhang, et al. 2005) This is clearly in the way the sun warms the surface of the earth, which involves the heat transfer through electromagnetic waves and absorption of the heat energy by a surface. Heat from the sun is reaches human skin as radiation, much of it can clearly be seen or evident light, the rest similar electromagnetic waves but at wavelengths human eyes are not sensitive to it. All bodies not at sheer zero temperature radiate, at room temperature the radiation is in the infrared, wavelengths longer than those of the visible spectrum. (Fowler, 2008) Source: isover Then, the types of thermal insulation are indicates the composition and internal structure of a building and the types of thermal insulation are normally been subdivided into three groups, which are fibrous insulation, cellular insulation and granular insulation.(Muhammad Anis-ur-Rehman, et al. 1999) 2.1.1.4 Fibrous Insulation Fibrous insulation is composing of air finely divided into interstices by small diameter fibers. The fibers may be parallel or perpendicular to the surface being insulated and they may separate or bonded together. That is usually chemically or mechanically bonded and formed into boards, blanket or hollow cylinders. (Muhammad Anis-ur-Rehman, et al. 1999) 2.1.1.5 Cellular Insulation Cellular insulation is composed of air or some other gas contained within foam of stable small bubbles and formed into boards, blankets, or hollow cylinders. The cellular material may be glass or foamed plastic such as polystyrene, polyurethane and elastomeric. (Muhammad Anis-ur-Rehman, et al. 1999) 2.1.1.6 Granular Insulation Granular insulation is composed of air or some other gas in the interstices between small granules and formed into blocks, boards, or hollow cylinders. This type may be produce as loose pourable material or combined with a binder and fibers to make a rigid insulation. (Muhammad Anis-ur-Rehman, et al. 1999) Furthermore, thermal insulation is available in a variety of forms and it is usually rated in terms of thermal resistance which is R-value, which indicates the resistance of material to heat flow. The higher its resistance is, the greater the insulating effectiveness is. Of course, the thermal insulation property depends on the type of material, its thickness, and its density. The combined form and type of insulation will determine the proper method of insulation. There are many forms of thermal insulation are designed to deliver a sustained level of thermal resistance, such as Traditional Batt Insulation or Alternatives, Blown-In Cellulose Insulation, Rigid Board Insulation, Spray Foam Insulation and SIPs/ICFs. 2.1.1.7 Traditional Batt Insulation or Alternatives Batt or Blanket Insulation is the most common and least effective insulation used in the states nowadays. It has an approximate rating of R-3 per inch. Technically the R rating is even lower because typical batts are so loose that they allow air to penetrate them and cool them down. It is possible to use batts effectively in energy efficient buildings but the installation is labor intensive. One slightly greener alternative to batts would be to use batts or rolls made of natural fibers such as Bonded Logics insulation made from recycled denim jeans.[8] These types of insulation typically have a slightly higher R rating and do not harm the indoor air quality since they are made of natural materials. The trade off is that they are pricey and still do not effectively seal air gaps without extra labor and supervision. (Ludeman, 2008) 2.1.1.8 Blown-In Cellulose Insulation Loose-Fill Insulation is an option that can be economic friendly because the Cellulose is a type of blown-in or loose-fill insulation that is made from recycled newspapers. There pros and cons but the bottom line is that it will not provide much better R- value than batt insulation and typically it will cost more to have installed. The best applications seem to be for attics that are not well insulated because cellulose can be quickly and efficiently blow over an attic floor to dramatically and safely increase the insulation between the home and the hot attic space. (Ludeman, 2008) 2.1.1.9 Rigid Board Insulation Rigid Board Insulation can contain some of the highest R-values with some Polyurethane sheets reaching R-8 per inch. Since the insulation comes in the form of rigid boards it is popular as roof and wall coverings attached to the exterior of the framing of a new building. Attaching to the exterior of the framing will improve the strength of the structure while also creating an insulated break or thermal barrier between the wood studs and the exterior sheathing or siding. This can greatly reduce the heat loss transferred from the inside of the building though the wood studs and to the exterior. There are also green versions of rigid board that are normally classified as polystyrene rigid insulation. This type may contain some recycled materials and will not off-gas like some of the other sheet products might. Besides that, rigid board insulation is also can find boards that are laminated or strengthened to act as both the buildings sheathing and insulation. Since sheathing of some type is necessary, this does not eliminate a step but can greatly improve the building envelope without additional labor. (Ludeman, 2008) 2.1.1.10 Spray Foam Insulation Spray-Foam Insulation is probably the most effective type of insulation for traditional, stick-framed buildings available nowadays. The product is in the form of a liquid that is sprayed on and quickly expands to 100 times its size. It can achieve R-values of R-9 per inch but most importantly, it automatically creates an almost perfect air seal upon expanding. While the product is costly, it is effective and reduces a lot of manual caulking and sealing that would be necessary with other types of insulations. The most popular forms are petroleum based but there are also green options such as BioBased Insulation that is composed of 96% bio-content (soy-beans). (Ludeman, 2008) 2.1.1.11 Structurally Insulated Panels (SIPs) / ICFs Structurally Insulated Panels are arguably the best way to achieve a tightly sealed and well insulated building. They are basically two sheets of OSB with spray foam insulation sandwiched between them. They are both structural as well as insulating so they eliminate the need for traditional framing and can streamline the construction of a building is assembled properly. All seams are sealed and there is no thermal bridge from studs. The only downfall is many contractors are unfamiliar with them and they can be quite pricey. Many of the green builders are using Structurally Insulated Panels because there are vehemently opposed to stick building as they view it an obsolete building practice. (Ludeman, 2008) Therefore, apply the thermal insulation for buildings will prevents or reduces heat from escaping a building or from entering a building. Thermal insulation can keep an enclosed area such as a building or a room warm for the cold climate countries like United Kingdom, Poland, New Zealand and so on; or it can keep the inside of a building or a room cold for the tropical climate countries such as Malaysia, Indonesia, Thailand, and so on. So, the thermal insulators are applied and functions to minimize that heat energy transfer from the buildings. In thermal insulation, the R-value is an indication of how well for a material insulates for the buildings. 2.1.1.12 R-value The R-value is the total thermal resistance (RT) for any building elements, including the surface thermal resistances of the air on either side of the building elements. The conductivity of bulk insulation materials will change with the temperature of the material. (Williamson, 2007) It is significant to realize that the boundary conditions and other factors used in the calculation of the R-values, which will cause the R-value different. The total thermal resistance of a flat for building element consisting of layers perpendicular to the heat flow is calculated using the expression: RT = Rsi + R1 + R2 + . . . . . + Rn + Rse Rsi is the internal surface resistance; R1, R2, .Rn are the thermal resistances of each layer, including bridged layers; Rse is the external surface resistance [Source: Dr Terry Williamson (2007)] An air space for the thermal resistance within a building element is depends on the valid emissivity of the space as well as the mean temperature and the difference in temperatures either side of the space.(Williamson, 2007) It follows therefore that the calculation of the R-value of a building element containing air spaces depends on the conditions assumed externally and internally.(Williamson, 2007) Thus, the flow of heat can be reduced by applying thermal insulation materials to the buildings and The rate of heat transfer is dependent on the physical properties of the material employed to do this. Insulation for the home has R-values usually in the range of R-10 up to R-30. The following is a listing of different materials with the English measurement of R-value: Material R-value Hardwood siding (1 in. thick) 0.91 Wood shingles (lapped) 0.87 Brick (4 in. thick) 4.00 Concrete block (filled cores) 1.93 Fiberglass batting (3.5 in. thick) 10.90 Fiberglass batting (6 in. thick) 18.80 Fiberglass board (1 in. thick) 4.35 Cellulose fiber (1 in. thick) 3.70 Flat glass (0.125 in thick) 0.89 Insulating glass (0.25 in space) 1.54 Air space (3.5 in. thick) 1.01 Free stagnant air layer 0.17 Drywall (0.5 in. thick) 0.45 Sheathing (0.5 in. thick) 1.32 [Source:  Hyperphysics Georgia State University] Another mathematical expression used in thermal quantification, and the most common reference used by the insulation industry, is U-value, or flow rate of heat through a building elements. 2.1.1.13 U-value U-value is to be used for describe the amount of heat loss or also called as thermal transmittance, that occurs through an element of construction such as a wall or window. (Raynham, 1975) If an element of construction has a lower the U-value the less energy is lost and the better is its insulating characteristics.(Zimmermann Bertschinger, 2001) It has the same unit as thermal conductivity, except that since a U-value refers to a given construction, the thickness of which is taken into account, it has the unit W m-2 K-1. U-value is computed according to the formula: U=(Ri s+ Re s,+Rc a v+k1-l+k2-1+†¦)-l Ri s and, Re s are the thermal resistances of internal and external surfaces respectively; Rc a v is the sum of thermal resistances of any cavities; k1-l+k2-1+†¦ are the thermal resistances of each material used. [Source: Mark Zimmerman Hans Bertschinger (2001)] Since the U-value is a measurement of heat flow, the lower the U-value, the more slowly does the material transfer heat in and out of the home. The U-value typically is used in expressing overall thermal conductance, since it is a measurement of the rate of heat flow through the complete heat barrier, from room air to outside air.(Anderson, 2006) The lower the U-value, the better is the insulating value. The U-value of a constructional element of buildings would decreases rapidly as the first few centimeters of thermal insulation are added.(Rouni, 2005) An even more increase in thermal insulation thickness does not always lead to an equally fast decrease in the U-value. The thicker the thermal insulation layer already is, the less the decrease in the U-value is by more adding thermal insulation.(Rouni, 2005) The following diagram shows the decrease in the U-value as the thickness of the insulation layer increases. [Source: GK Rouni (2005)] Temperature and temperature variations govern much of our daily lives, the environmental factors such as temperature, radiation, air motion, and humidity, as well as on personal factors such as activity levels, clothing selection and expectation, all of those factors are contribute to the state of thermal comfort.(Bynum, 2000) Thermal comfort is a term given the varying nature of the human condition, has been described as a feeling of well-being, an absence of discomfort, or a state of mind that is satisfied with the thermal environment. (McDowall, 2007) 2.1.2 – Uses of thermal insulation The human beings have demonstrated that we are need for the protection from the elements of construction and although many of these factors are continuously in flux, but the proper use of thermal insulation, placement of vapor barriers, and understanding of heat transfer will contribute to providing an environment conducive to thermal comfort within the buildings to the human.(Bynum, 2000) Thermal insulation is the better way to protect anything against the heat because the material use for this is really heat absorbing material. Thermal insulation is to be used to perform many of the functions and the primary purpose of thermal insulation is to reduce heat loss or heat gain through the exterior assemblies of a building in order to achieve energy conservation.(Stettler, 2009) Basically thermal insulations reduce the rate of heat transfer because there are special type of thermal insulation material which converts the heat energy to some other form by conduction, convention and radiation as mentioned as foresaid. [Source: exergia] As the drawing shows that the houses lose heat through walls, windows, doors, floors, roofs and ventilation.  Thermal insulation, quality double-glazed windows and controlled ventilation can reduce the heat losses by as much as 50%, thus reducing the heating costs in the cold climate.(Weber, 2006) However, an energy efficient home featuring thermal insulation, shading, brightly colored external surfaces and controlled ventilation also greatly enhance the thermal comfort by offering protection from the heat and radiation of the sun. (Weber, 2006)  This also helps to drastically reduce the electrical bills that pay to run air conditioners in tropical climate. Besides that, apply thermal insulation for buildings will protect the environment through the reduction of Chlorofluorocarbon (CFC), Carbon Dioxide (CO2), Nitrogen Oxide (NOx) and greenhouse gases. (Stettler, 2009) The greenhouse effect to a great level decides the climate on earth. Growth in emissions of greenhouse gases related with human activities menaces the climate balance. Chlorofluorocarbon (CFC) and Carbon Dioxide (CO2) are the main greenhouse gas which are emitted due to air-conditioners are function to provide cool or hot air and increasing thermal comfort of buildings, there have led to rapid growth in the amount of Chlorofluorocarbon (CFC) and Carbon Dioxide (CO2) in the a atmosphere. Heating, air conditioning and refrigeration are the causes that result in this growth. If no action is taken at all, the EU Member States said that greenhouse gas emissions could be expected to further increase by 17% between 1990 and 2010, while the target set by the Kyoto Protocol for the period is to reduce the emissions by 8%. The reasonable level of expenditure on insulation is directly related to the amount of the heat loss or heat gain, and to the electricity of air-conditioning required to produce an appreciable return in terms of electricity saving. Fortunately, it is possible to reduce energy consumption and the associated Chlorofluorocarbon (CFC) and Carbon Dioxide (CO2) emissions in heating and air conditioning by one third by using more or better insulation for the buildings.(Roberts, et al. 1981) Furthermore, the thermal insulation also can be used in buildings in order to prevent or reduce condensation on surfaces.(Raynham 1973) If wants to prevent condensation on the surface of walls, it is necessary to have adequate ventilation and sufficient insulation and heat input. It is also necessary to consider the question of whether condensation is likely to occur within a structure. Since most structures experience a falling dew point especially where insulating internal linings are provided, as well as temperature gradient from inside to out, it is possible for the temperature on the cold side of the insulation to fall below the dew point, causing interstitial condensation.(Raynham 1973) This can be controlled by providing water vapour barriers on the warm side of the insulation. This may take the form of polythene film or certain types of paint treatment, such as chlorinated rubber on the insulated lining. In some situations such as factory roofs and some timber flat roofs, ventilation is provided above the insulation to remove any water vapour that has penetrated that far.(Raynham 1973) Thermal insulation also can use to prevent or reduce damage to buildings when occur fire in the buildings or near the buildings.(Raynham 1973) When fire breaks out in a compartment the contents of the whole room are heated up, leading to accumulation of flammable gas. Eventually a point is reached when these gases, together with the materials evolving them, suddenly kindle and thus involve the whole room in fire. Tests done many years ago at the Fire Research Station (Raynham 1973) investigated the factors leading to a short, and therefore dangerous, flashover time. Tests involving fires in domestic sized rooms with insulating board and hardboard wall linings showed that flashover occurred at between 8.5 and 12min. Two further tests made with a noncombustible sprayed insulating lining gave flashover times of 8 and 4.5 min, thus suggesting that the thermal insulating characteristics of a lining are probably more significant from a fire development point of view than its combustibility. If this is true to any extent, significantly improved standards of thermal insulation, such as we are about to adopt in this country, are almost certain to accentuate the fire risk, especially in dwellings. The thermal insulation also can be installed in the mechanical system in commercial buildings and industrial processes.(Avtivity, 2008) In buildings such as shopping centers, schools, hospitals, and hotels, mechanical insulations are installed to improve the energy consumption of the cooling and heating systems for buildings, domestic hot and cold water supply, and refrigerated systems including ducts and housings. However, for industrial facilities such as power plants, refineries, and paper mills, mechanical thermal insulations are installed to control heat gain or heat loss on process piping and equipment, steam and condensate distribution systems, boilers, smoke stacks, bag houses and precipitators, and storage tanks.(Avtivity, 2008) Thermal insulation for mechanical system is to dominate the temperatures of the surface for personnel and equipment protection. That is one of the most effective mediums of protecting workers from second and third degree burns resulting from skin contact for more than 5 seconds with surfaces of hot piping and equipment operating at temperatures above 136.4 °F.(Avtivity, 2008) Thermal insulation will function to reduces the surface temperature of piping or equipment into a safer level as required by OSHA, resulting in increased worker safety and the avoidance of worker downtime due to injury.(Avtivity, 2008) Besides, thermal insulation also will control the temperature of commercial and industrial processes when installed in the mechanical system.(Avtivity, 2008) Thermal insulation can help maintain process temperature to a pre-determined value or within a predetermined range by reducing heat loss or gain. The insulation thickness must be sufficient to limit the heat transfer in a dynamic system or limit the temperature change, with time, in a static system.(Avtivity, 2008) The need to provide time for owners to take remedial action in emergency situations in the event of loss of electrical power, or heat sources is a major reason for this action in a static system. At last but not least, installed the thermal insulation in the mechanical system will reduce noise from mechanical systems.(Avtivity, 2008) Insulation materials can be used in the design of an assembly having a high sound attenuation or sound resistance. The sound transmission loss when the thermal insulation to be installed between the source and the surrounding area.(Avtivity, 2008) So, thermal insulation not only can be used for building but also for the mechanical system in commercial buildings and industrial processes in order to achieve different effects. 2.2 – The importance or advantages of thermal insulation in Malaysia 2.2.1 – Advantages of thermal insulation in Malaysia Governments all over the world are beginning to recognize the significance of reducing dependence on energy imports as fuel reserves becomes scarcer and supplies are focused on a few politically unstable countries. In the Malaysian context, the ener Application of Thermal Insulation Application of Thermal Insulation 1.2 Problem Statement Energy saving in buildings has become a question of crucial importance in many countries. At the same time, the requirements for satisfactory indoor climate with low electricity consumption have increased which prompt the supply and demand for energy efficient homes. The battle against global warming shall start from home insulation to reduce green house gas emission. In developed countries, government has even allowed tax credit to house owners for costs incurred in carrying out home insulation works which meets the urgent need in the fight against global warming. In Malaysia, the common answer from the public in general to make a house or office cool is probably by switching on the air conditioning. The roof of most houses is constructed using timber roof trusses and concrete roof tiles in Malaysia. The heat gained through the roof which convents through the ceiling has increased the indoor heat to a level that most house owners will not feel comfortable without the use of air cond itioners. The impact that roofs have on energy is often overlooked, the impact of which can be significant. In homes, air conditioners make up 23% of energy consumption. Alternatively we can achieve the dream cool and comfort living or working environment despite in a very hot sunny day with the help of install the thermal insulation then will reduce the dependence on air conditioners to cool the home or office. This means insulating a home could potentially save thousands of ringgit in electricity bills. Install the thermal insulation in the wall or roof will increasing the cost of the building but the price tag on insulation is considered small when compared with the benefits including monthly savings in electricity bills throughout the lifespan of the house, reduced greenhouse gas emissions, improved comfort and living standards and a huge contribution to the local economic growth, as the insulation material is manufactured locally. 1.3 Aim The researchers aim for conducting this research is to review the uses and identify the importance of thermal insulation. Besides that, to find out whether application of thermal insulation to the buildings is suitable to be adopted into construction industry in Malaysia. 1.4 Objectives To review the concepts and uses of thermal insulation. To assess the importance or advantages of thermal insulation in Malaysia. To investigate the applicability of thermal insulation amongst the buildings in Malaysia. 1.5 Hypothesis Application of thermal insulation into the buildings would increase the energy saving in buildings and decrease in emission to environmental. 1.6 Background Governments all over the world are beginning to realize the importance of reducing dependence on energy imports as fuel reserves becomes scarcer and supplies are concentrated on a few politically unstable countries. The building sector is probably the most effective and easiest way to start reducing energy consumption. Reduction in energy demand can be most effective due to applying thermal insulation to the buildings. Thermal insulation is the method of preventing heat from escaping a container or from entering the container. In other words, thermal insulation can keep an enclosed area such as a building warm, or it can keep the inside of a container cold. Depending on the climate, we spend more or less energy on heating or cooling, but we will spend more energy on cooling the room by switch on the air conditioning in Malaysia. There have a main reason for using thermal insulation for reduction of heat coming in, without too much loss of light due to the hot climate in Malaysia. So, the demand of energy can be significantly reduced by install a thermal insulation into the wall or roof of those buildings. Thermal insulation has been introduced to reduce the demand of energy result in electric consumption costs up to 40% and the countrys energy resources. This allows savings on the cost of the air-conditioning, because a smaller unit is needed, and on the running cost of the air conditioning. It also indeed creates a more comfortable living and working atmosphere. Besides that, most of the people will switch on the air conditioning to keep the comfort in the room or working place in Malaysia. But, the air conditioners will release a haloalkanes which are a group of chemical compounds, consisting of chlorine, fluorine and carbon, called Chlorofluorocarbons (CFC). The CFC will among the greenhouse gases in the atmosphere that contribute to future global warming. So, apply thermal insulation to the buildings will reduce using the air conditioning naturally will reduce the emission to the environmental also. 1.7 Scope of Study The research project has provided the idea and functions of thermal insulation to the buildings make a preliminary of understanding to it. Besides that, the advantages or importances that apply the thermal insulation to the buildings in Malaysia also fall within the scopes of this research project. In this study, I have studied into few buildings in Malaysia which have installed the thermal insulation such as Pusat Tenaga Malaysia Zero Energy Office (ZEO) building at Bandar Baru Bangi and Low Energy Office (LEO) Ministry of Energy, Water and Communications Malaysia at Putrajaya. Based on these buildings, I will study the benefits that obtain from the buildings which have applied thermal insulation to the wall and roof in this research project. In addition, I will inquire into the applicability of thermal insulation in the buildings in Malaysia. 1.8 Research Methodology For the primary source, questionnaires were prepared as a ground for the main survey which relates to the reason of construction firms attempt to apply thermal insulation to the buildings in Malaysia. The questionnaires were then distributed to the construction firms which are be responsible for ‘Pusat Tenaga Malaysia Zero Energy Office (ZEO) building project and ‘Low Energy Office (LEO) Ministry of Energy, Water and Communications Malaysia through e-mail. For this purpose of survey, mailing list was obtained for website which has listing the name, address and the title of principal officer for each firm listed. That company was chosen and sent a set of questionnaire while those company which have not related into the projects will be randomly chosen for obtain the opinion on the applicability of apply thermal insulation in the buildings in Malaysia. For secondary sources, a comprehensive review of the relevant literature including a computer assisted search, textbook, journals, articles and so on, will be taken to develop an understanding of concept and uses of thermal insulation. Besides that, the importance or advantages of thermal insulation in Malaysia also will be assessed by computer assisted search. 1.9 Proposed structure of the dissertation Chapter 1: Introduction.

Available on: www.mimg.org.my/images/pdf/MIMG_Why_Insulate.pdf 2.0 Literature Review 2.1 Review the concepts and uses of thermal insulation 2.1.1 – Concept of thermal insulation Thermal insulation has been defined as a material or combination of materials which slow down the flow of heat, reduce some sound transmission or slow down the spread of fire when buildings are in fire.(Anish, 2003) The thermal insulation materials can be suited to any size, shape or surface and the variety of finishes to be used in order to protect the thermal insulation from mechanical and environmental damage as well as to enhance appearance of buildings.(Anish, 2003) Thermal insulation can be mentioned either to materials used to lower the rate of heat transfer, or the means and processes used to lower heat transfer. Thermal insulation will transfer heat energy and the hHYPERLINK http://en.wikipedia.org/wiki/Heateat energy would be transferred by three methods, which are convection, conduction and radiation. 2.1.1.1 Convection When the heat is flow whether by forced or natural, within a fluid and the fluid is a substance that may be either a gas or a liquid, this process is called convection.(Zhang, et al. 2005) Convection will then gravitationally-induced heat transport, driven by the expansion of a fluid on heating then hot expanded fluid has lower density, so will rise to the top of colder, and therefore denser, fluid.(Fowler, 2008) For example, when air to be heated, then it will expands and rise. However, if the air movement is established mechanically by a floor register, fan, or wind, then it will be called as a forced convection. 2.1.1.2 Conduction Conduction is direct heat flow or conducted from a material especially a solid.(Zhang, et al. 2005) When different parts of an isolated solid are at different temperatures, the heat will flow from the hot places to the cold places until eventually all is at the same temperature.(Fowler, 2008) Conduction and convection have same uses which are functions of the roughness of surfaces, air movement and the temperature difference between the air and surface. The increasing of heat energy can flow through materials and from one material to another.(Kurtus, 2006) 2.1.1.3 Radiation Radiation is the transmission of energy through space by means of electromagnetic waves.(Zhang, et al. 2005) This is clearly in the way the sun warms the surface of the earth, which involves the heat transfer through electromagnetic waves and absorption of the heat energy by a surface. Heat from the sun is reaches human skin as radiation, much of it can clearly be seen or evident light, the rest similar electromagnetic waves but at wavelengths human eyes are not sensitive to it. All bodies not at sheer zero temperature radiate, at room temperature the radiation is in the infrared, wavelengths longer than those of the visible spectrum. (Fowler, 2008) Source: isover Then, the types of thermal insulation are indicates the composition and internal structure of a building and the types of thermal insulation are normally been subdivided into three groups, which are fibrous insulation, cellular insulation and granular insulation.(Muhammad Anis-ur-Rehman, et al. 1999) 2.1.1.4 Fibrous Insulation Fibrous insulation is composing of air finely divided into interstices by small diameter fibers. The fibers may be parallel or perpendicular to the surface being insulated and they may separate or bonded together. That is usually chemically or mechanically bonded and formed into boards, blanket or hollow cylinders. (Muhammad Anis-ur-Rehman, et al. 1999) 2.1.1.5 Cellular Insulation Cellular insulation is composed of air or some other gas contained within foam of stable small bubbles and formed into boards, blankets, or hollow cylinders. The cellular material may be glass or foamed plastic such as polystyrene, polyurethane and elastomeric. (Muhammad Anis-ur-Rehman, et al. 1999) 2.1.1.6 Granular Insulation Granular insulation is composed of air or some other gas in the interstices between small granules and formed into blocks, boards, or hollow cylinders. This type may be produce as loose pourable material or combined with a binder and fibers to make a rigid insulation. (Muhammad Anis-ur-Rehman, et al. 1999) Furthermore, thermal insulation is available in a variety of forms and it is usually rated in terms of thermal resistance which is R-value, which indicates the resistance of material to heat flow. The higher its resistance is, the greater the insulating effectiveness is. Of course, the thermal insulation property depends on the type of material, its thickness, and its density. The combined form and type of insulation will determine the proper method of insulation. There are many forms of thermal insulation are designed to deliver a sustained level of thermal resistance, such as Traditional Batt Insulation or Alternatives, Blown-In Cellulose Insulation, Rigid Board Insulation, Spray Foam Insulation and SIPs/ICFs. 2.1.1.7 Traditional Batt Insulation or Alternatives Batt or Blanket Insulation is the most common and least effective insulation used in the states nowadays. It has an approximate rating of R-3 per inch. Technically the R rating is even lower because typical batts are so loose that they allow air to penetrate them and cool them down. It is possible to use batts effectively in energy efficient buildings but the installation is labor intensive. One slightly greener alternative to batts would be to use batts or rolls made of natural fibers such as Bonded Logics insulation made from recycled denim jeans.[8] These types of insulation typically have a slightly higher R rating and do not harm the indoor air quality since they are made of natural materials. The trade off is that they are pricey and still do not effectively seal air gaps without extra labor and supervision. (Ludeman, 2008) 2.1.1.8 Blown-In Cellulose Insulation Loose-Fill Insulation is an option that can be economic friendly because the Cellulose is a type of blown-in or loose-fill insulation that is made from recycled newspapers. There pros and cons but the bottom line is that it will not provide much better R- value than batt insulation and typically it will cost more to have installed. The best applications seem to be for attics that are not well insulated because cellulose can be quickly and efficiently blow over an attic floor to dramatically and safely increase the insulation between the home and the hot attic space. (Ludeman, 2008) 2.1.1.9 Rigid Board Insulation Rigid Board Insulation can contain some of the highest R-values with some Polyurethane sheets reaching R-8 per inch. Since the insulation comes in the form of rigid boards it is popular as roof and wall coverings attached to the exterior of the framing of a new building. Attaching to the exterior of the framing will improve the strength of the structure while also creating an insulated break or thermal barrier between the wood studs and the exterior sheathing or siding. This can greatly reduce the heat loss transferred from the inside of the building though the wood studs and to the exterior. There are also green versions of rigid board that are normally classified as polystyrene rigid insulation. This type may contain some recycled materials and will not off-gas like some of the other sheet products might. Besides that, rigid board insulation is also can find boards that are laminated or strengthened to act as both the buildings sheathing and insulation. Since sheathing of some type is necessary, this does not eliminate a step but can greatly improve the building envelope without additional labor. (Ludeman, 2008) 2.1.1.10 Spray Foam Insulation Spray-Foam Insulation is probably the most effective type of insulation for traditional, stick-framed buildings available nowadays. The product is in the form of a liquid that is sprayed on and quickly expands to 100 times its size. It can achieve R-values of R-9 per inch but most importantly, it automatically creates an almost perfect air seal upon expanding. While the product is costly, it is effective and reduces a lot of manual caulking and sealing that would be necessary with other types of insulations. The most popular forms are petroleum based but there are also green options such as BioBased Insulation that is composed of 96% bio-content (soy-beans). (Ludeman, 2008) 2.1.1.11 Structurally Insulated Panels (SIPs) / ICFs Structurally Insulated Panels are arguably the best way to achieve a tightly sealed and well insulated building. They are basically two sheets of OSB with spray foam insulation sandwiched between them. They are both structural as well as insulating so they eliminate the need for traditional framing and can streamline the construction of a building is assembled properly. All seams are sealed and there is no thermal bridge from studs. The only downfall is many contractors are unfamiliar with them and they can be quite pricey. Many of the green builders are using Structurally Insulated Panels because there are vehemently opposed to stick building as they view it an obsolete building practice. (Ludeman, 2008) Therefore, apply the thermal insulation for buildings will prevents or reduces heat from escaping a building or from entering a building. Thermal insulation can keep an enclosed area such as a building or a room warm for the cold climate countries like United Kingdom, Poland, New Zealand and so on; or it can keep the inside of a building or a room cold for the tropical climate countries such as Malaysia, Indonesia, Thailand, and so on. So, the thermal insulators are applied and functions to minimize that heat energy transfer from the buildings. In thermal insulation, the R-value is an indication of how well for a material insulates for the buildings. 2.1.1.12 R-value The R-value is the total thermal resistance (RT) for any building elements, including the surface thermal resistances of the air on either side of the building elements. The conductivity of bulk insulation materials will change with the temperature of the material. (Williamson, 2007) It is significant to realize that the boundary conditions and other factors used in the calculation of the R-values, which will cause the R-value different. The total thermal resistance of a flat for building element consisting of layers perpendicular to the heat flow is calculated using the expression: RT = Rsi + R1 + R2 + . . . . . + Rn + Rse Rsi is the internal surface resistance; R1, R2, .Rn are the thermal resistances of each layer, including bridged layers; Rse is the external surface resistance [Source: Dr Terry Williamson (2007)] An air space for the thermal resistance within a building element is depends on the valid emissivity of the space as well as the mean temperature and the difference in temperatures either side of the space.(Williamson, 2007) It follows therefore that the calculation of the R-value of a building element containing air spaces depends on the conditions assumed externally and internally.(Williamson, 2007) Thus, the flow of heat can be reduced by applying thermal insulation materials to the buildings and The rate of heat transfer is dependent on the physical properties of the material employed to do this. Insulation for the home has R-values usually in the range of R-10 up to R-30. The following is a listing of different materials with the English measurement of R-value: Material R-value Hardwood siding (1 in. thick) 0.91 Wood shingles (lapped) 0.87 Brick (4 in. thick) 4.00 Concrete block (filled cores) 1.93 Fiberglass batting (3.5 in. thick) 10.90 Fiberglass batting (6 in. thick) 18.80 Fiberglass board (1 in. thick) 4.35 Cellulose fiber (1 in. thick) 3.70 Flat glass (0.125 in thick) 0.89 Insulating glass (0.25 in space) 1.54 Air space (3.5 in. thick) 1.01 Free stagnant air layer 0.17 Drywall (0.5 in. thick) 0.45 Sheathing (0.5 in. thick) 1.32 [Source:  Hyperphysics Georgia State University] Another mathematical expression used in thermal quantification, and the most common reference used by the insulation industry, is U-value, or flow rate of heat through a building elements. 2.1.1.13 U-value U-value is to be used for describe the amount of heat loss or also called as thermal transmittance, that occurs through an element of construction such as a wall or window. (Raynham, 1975) If an element of construction has a lower the U-value the less energy is lost and the better is its insulating characteristics.(Zimmermann Bertschinger, 2001) It has the same unit as thermal conductivity, except that since a U-value refers to a given construction, the thickness of which is taken into account, it has the unit W m-2 K-1. U-value is computed according to the formula: U=(Ri s+ Re s,+Rc a v+k1-l+k2-1+†¦)-l Ri s and, Re s are the thermal resistances of internal and external surfaces respectively; Rc a v is the sum of thermal resistances of any cavities; k1-l+k2-1+†¦ are the thermal resistances of each material used. [Source: Mark Zimmerman Hans Bertschinger (2001)] Since the U-value is a measurement of heat flow, the lower the U-value, the more slowly does the material transfer heat in and out of the home. The U-value typically is used in expressing overall thermal conductance, since it is a measurement of the rate of heat flow through the complete heat barrier, from room air to outside air.(Anderson, 2006) The lower the U-value, the better is the insulating value. The U-value of a constructional element of buildings would decreases rapidly as the first few centimeters of thermal insulation are added.(Rouni, 2005) An even more increase in thermal insulation thickness does not always lead to an equally fast decrease in the U-value. The thicker the thermal insulation layer already is, the less the decrease in the U-value is by more adding thermal insulation.(Rouni, 2005) The following diagram shows the decrease in the U-value as the thickness of the insulation layer increases. [Source: GK Rouni (2005)] Temperature and temperature variations govern much of our daily lives, the environmental factors such as temperature, radiation, air motion, and humidity, as well as on personal factors such as activity levels, clothing selection and expectation, all of those factors are contribute to the state of thermal comfort.(Bynum, 2000) Thermal comfort is a term given the varying nature of the human condition, has been described as a feeling of well-being, an absence of discomfort, or a state of mind that is satisfied with the thermal environment. (McDowall, 2007) 2.1.2 – Uses of thermal insulation The human beings have demonstrated that we are need for the protection from the elements of construction and although many of these factors are continuously in flux, but the proper use of thermal insulation, placement of vapor barriers, and understanding of heat transfer will contribute to providing an environment conducive to thermal comfort within the buildings to the human.(Bynum, 2000) Thermal insulation is the better way to protect anything against the heat because the material use for this is really heat absorbing material. Thermal insulation is to be used to perform many of the functions and the primary purpose of thermal insulation is to reduce heat loss or heat gain through the exterior assemblies of a building in order to achieve energy conservation.(Stettler, 2009) Basically thermal insulations reduce the rate of heat transfer because there are special type of thermal insulation material which converts the heat energy to some other form by conduction, convention and radiation as mentioned as foresaid. [Source: exergia] As the drawing shows that the houses lose heat through walls, windows, doors, floors, roofs and ventilation.  Thermal insulation, quality double-glazed windows and controlled ventilation can reduce the heat losses by as much as 50%, thus reducing the heating costs in the cold climate.(Weber, 2006) However, an energy efficient home featuring thermal insulation, shading, brightly colored external surfaces and controlled ventilation also greatly enhance the thermal comfort by offering protection from the heat and radiation of the sun. (Weber, 2006)  This also helps to drastically reduce the electrical bills that pay to run air conditioners in tropical climate. Besides that, apply thermal insulation for buildings will protect the environment through the reduction of Chlorofluorocarbon (CFC), Carbon Dioxide (CO2), Nitrogen Oxide (NOx) and greenhouse gases. (Stettler, 2009) The greenhouse effect to a great level decides the climate on earth. Growth in emissions of greenhouse gases related with human activities menaces the climate balance. Chlorofluorocarbon (CFC) and Carbon Dioxide (CO2) are the main greenhouse gas which are emitted due to air-conditioners are function to provide cool or hot air and increasing thermal comfort of buildings, there have led to rapid growth in the amount of Chlorofluorocarbon (CFC) and Carbon Dioxide (CO2) in the a atmosphere. Heating, air conditioning and refrigeration are the causes that result in this growth. If no action is taken at all, the EU Member States said that greenhouse gas emissions could be expected to further increase by 17% between 1990 and 2010, while the target set by the Kyoto Protocol for the period is to reduce the emissions by 8%. The reasonable level of expenditure on insulation is directly related to the amount of the heat loss or heat gain, and to the electricity of air-conditioning required to produce an appreciable return in terms of electricity saving. Fortunately, it is possible to reduce energy consumption and the associated Chlorofluorocarbon (CFC) and Carbon Dioxide (CO2) emissions in heating and air conditioning by one third by using more or better insulation for the buildings.(Roberts, et al. 1981) Furthermore, the thermal insulation also can be used in buildings in order to prevent or reduce condensation on surfaces.(Raynham 1973) If wants to prevent condensation on the surface of walls, it is necessary to have adequate ventilation and sufficient insulation and heat input. It is also necessary to consider the question of whether condensation is likely to occur within a structure. Since most structures experience a falling dew point especially where insulating internal linings are provided, as well as temperature gradient from inside to out, it is possible for the temperature on the cold side of the insulation to fall below the dew point, causing interstitial condensation.(Raynham 1973) This can be controlled by providing water vapour barriers on the warm side of the insulation. This may take the form of polythene film or certain types of paint treatment, such as chlorinated rubber on the insulated lining. In some situations such as factory roofs and some timber flat roofs, ventilation is provided above the insulation to remove any water vapour that has penetrated that far.(Raynham 1973) Thermal insulation also can use to prevent or reduce damage to buildings when occur fire in the buildings or near the buildings.(Raynham 1973) When fire breaks out in a compartment the contents of the whole room are heated up, leading to accumulation of flammable gas. Eventually a point is reached when these gases, together with the materials evolving them, suddenly kindle and thus involve the whole room in fire. Tests done many years ago at the Fire Research Station (Raynham 1973) investigated the factors leading to a short, and therefore dangerous, flashover time. Tests involving fires in domestic sized rooms with insulating board and hardboard wall linings showed that flashover occurred at between 8.5 and 12min. Two further tests made with a noncombustible sprayed insulating lining gave flashover times of 8 and 4.5 min, thus suggesting that the thermal insulating characteristics of a lining are probably more significant from a fire development point of view than its combustibility. If this is true to any extent, significantly improved standards of thermal insulation, such as we are about to adopt in this country, are almost certain to accentuate the fire risk, especially in dwellings. The thermal insulation also can be installed in the mechanical system in commercial buildings and industrial processes.(Avtivity, 2008) In buildings such as shopping centers, schools, hospitals, and hotels, mechanical insulations are installed to improve the energy consumption of the cooling and heating systems for buildings, domestic hot and cold water supply, and refrigerated systems including ducts and housings. However, for industrial facilities such as power plants, refineries, and paper mills, mechanical thermal insulations are installed to control heat gain or heat loss on process piping and equipment, steam and condensate distribution systems, boilers, smoke stacks, bag houses and precipitators, and storage tanks.(Avtivity, 2008) Thermal insulation for mechanical system is to dominate the temperatures of the surface for personnel and equipment protection. That is one of the most effective mediums of protecting workers from second and third degree burns resulting from skin contact for more than 5 seconds with surfaces of hot piping and equipment operating at temperatures above 136.4 °F.(Avtivity, 2008) Thermal insulation will function to reduces the surface temperature of piping or equipment into a safer level as required by OSHA, resulting in increased worker safety and the avoidance of worker downtime due to injury.(Avtivity, 2008) Besides, thermal insulation also will control the temperature of commercial and industrial processes when installed in the mechanical system.(Avtivity, 2008) Thermal insulation can help maintain process temperature to a pre-determined value or within a predetermined range by reducing heat loss or gain. The insulation thickness must be sufficient to limit the heat transfer in a dynamic system or limit the temperature change, with time, in a static system.(Avtivity, 2008) The need to provide time for owners to take remedial action in emergency situations in the event of loss of electrical power, or heat sources is a major reason for this action in a static system. At last but not least, installed the thermal insulation in the mechanical system will reduce noise from mechanical systems.(Avtivity, 2008) Insulation materials can be used in the design of an assembly having a high sound attenuation or sound resistance. The sound transmission loss when the thermal insulation to be installed between the source and the surrounding area.(Avtivity, 2008) So, thermal insulation not only can be used for building but also for the mechanical system in commercial buildings and industrial processes in order to achieve different effects. 2.2 – The importance or advantages of thermal insulation in Malaysia 2.2.1 – Advantages of thermal insulation in Malaysia Governments all over the world are beginning to recognize the significance of reducing dependence on energy imports as fuel reserves becomes scarcer and supplies are focused on a few politically unstable countries. In the Malaysian context, the ener
