Energy Consumption In The Industry Construction Essay

Energy Consumption In The Industry Construction Essay This part of the report, is addressing to the energy use in construction and the actions that government and construction industry done so far in order to reduce carbon emissions and achieve sustainability. The major energy used in construction is by the machineries and also on the transportation of the materials to the site. Transportation accounts for 40% of all energy use in construction. The major energy consumers on site are construction equipment plants such as backhoe loaders; dampers; hydraulic excavators; cranes; etc. All the terms and conditions in the government and construction industry have to stop support and sponsoring the atomic and fossil energy. Is time for everyone to look straight to the renewable energy and sources? Large amount of money are being spent per annum in order for a certain household to be working normally. Innovated energy schemes must be solely persisted on comprehensive national and global calculations. Those calculations results prove that the atomic and fossil sources of energy are inconsiderable more expensive than those based on alternative Energy sources are. Those added expenses of energy use developed an overwhelming social and environment chaotic debt for the new generations. Renewable energy/fuel options can be introduced and replace the atomic and fossil energy/fuel. Meanwhile they produce the energy that buildings need to either be constructed or work, are more convenient ways and also more friendly to the environment. Construction plays a major part of the energy consumed in UK, accounts for approximately 50%. In the past the main energy consumption was used for heating, but now due to the climate distortions the demands for increasing energy also for cooling. These resulted to an extensive big cost, especially in the UK. The UK Government consequently has striving targets to reduce the amount of CO2 emissions. This will unavoidably oblige further tightening of building codes beyond the changes in 2006 and 2007 respectively to Part L of the Building Regulations for England and Wales, and Section 6 of the Building Standards (Scotland) (1). Most of the actions have been concentrated on the emissions associated to energy use in buildings. Moreover the arising issues of the embedded energy in materials, and the energy used in the transportations of the materials linked with construction has a big influence. The construction and transportation of building materials uses huge amounts of oil, gas, coal a nd electricity. The creation of this embedded energy has its own environmental issues such as arising of the emissions of CO2 and water and air pollutions. During the various phases of construction, energy consumes. From the material extraction to construction and therefore to the transportation and from site construction to demolition. During the transportation of materials to site and waste from site energy will also be used. The methods that involve energy use have been calculated and are as follows (2): -the material extraction, and therefore their fabrication -the transportation of the materials -transportation of the recycled materials -the construction and demolition procedures on the site -the transportation of the wastes -the transportation of the construction and demolitions wastes The amount of CO2 emissions that construction can influence is significant, accounting for almost 47% of total CO2 emissions of the UK. Due to that fact, UK government set target and adopted the strategy to transform the UK into a low-carbon nation by taking into account any possible alterations in energy consumption and possible contribution of alternative sources. Numerous actions have been undertaken in order reducing the co2 emissions due construction. Those actions involved the alteration of the code for building regulations zero carbon houses by maximising the use of energy efficiency and renewable energy sources from 2016 and onwards. In June 2008, UK government published Strategy for sustainable construction, 2008, which incorporate the targets 15% reduction in carbon emissions from construction processes and associated transport compared to 2008 levels (3), 25% of products used in construction projects to be from schemes recognised for responsible sourcing (3) and all construction projects in excess of  £1 million to have biodiversity surveys carried out and necessary actions instigated (3) (4). We are going to mainly focus on the 15% reduction in carbon emissions from construction processes and associated transport compared to 2008 levels (3). (2) The biggest sources of carbon emissions according to the 2008 baseline assessment have been identified. This Action Plan concentrates on the following points: †¢ On site construction (plant and equipment) †¢ Corporate offices †¢ Transport (delivery of materials to the site and removal of waste from the site) †¢ Business travel The Figure 1 below, reviews and sums up the recommended actions that can be done to proceed towards accomplishing the construction carbon reduction target of 15%. We are only concentrated to five actions that cover the two bullet points above (On site construction (plant and equipment) and Transport (delivery of materials to the site and removal of waste from the site), only as they are the most important in the action plan, and will be therefore discuss in detail below the Figure 1 (2). Energy efficient site accommodation (2) Often the insulation at temporary offices at construction sites are poor and unlike permanent buildings do not have the equivalent building management controls. Cabins that have been properly designed and managed have demonstrated to achieve the equivalent energy efficiency standards as permanent buildings. Carbon dioxide emissions can be reduced by 50% or more using these green cabins compared to traditional temporary accommodation.7 Energy efficient site accommodation implements both the use of new energy efficiency and the redevelopment of8 existing cabin supply before the cabins are sent off again on a project site. To begin with the industry would come to an agreement on specifications on the new redeveloped cabins. These Specifications would deal with the insulation including extra padding, the glazing of windows, heating which is more economical, lighting systems with built in motion sensors, a meter that reads the electricity, a thermostat, master switch for all appliances. The key issues for this action is there isnt an approved specification for energy efficient site accommodation and moreover the cost issues that arising by installing the greener cabins. Also the redeveloping of the existing cabins is complex task and has therefore more expenses. Big challenge that remains is to achieve this goal before 2012 and is really hard to see any results as would take time to redevelop all the existing stock. (2) Efficient use of construction plant (2) There are numerous policies for the efficient use of construction equipment plant such as: -Avoid massive machines that cause inefficiency and select the appropriate machine for the construction undertaking and Make a selection of the appropriate plant that is uses considerably smaller amount of fuel (2) Address to more sustainable fuels that are more energy efficient (2) Use the plant properly (2) Servicing plant economically and not wastefully by reducing the idling time (2) Operating plant efficiently (e.g. minimizing idling and make use of a suitable power) (2) All of the above action concentrates on encouraging the operators of the plant to run any construction equipment plant more efficiently. Additionally to permit contractors and clients to be supportive of fuel-efficient plants, the plant suppliers must improve and advertise constant fuel consumption targets. The issues with this are that the execution of this proposal would be hard for people to agree to as the cost of adopting the fuel-efficient plants would be set by the supplier and also the staff have to be trained and this wasting the time of the development to be constructed. (2) Earlier connection to the grid (2) On large construction sites power generators use large amounts of fuel so to minimise the amount of fuels used by the generators it would be more feasible to have the site connected to the national grid as early on in the construction as possible. This in turn would reduce CO2 emissions by a large amount. It requires though a series of steps to accomplished that. The issues with this are that having the site connected would take time as energy suppliers must go through checks, coordinate themselves with other groups they may be in conjunction with and then at a date that they are available will you be connected. Delays in large construction works will be very expensive. (2) Fuel-efficient freight driving and renewable transport fuels (2) The Strategies considered for lowering the carbon emissions on the transportation of materials to site and waste from it are as follows: Use of vehicles that are more fuel efficient (2) Decreasing the quantities of materials transported (2) Use vehicles that consume low quantities of carbon fuels (hybrid vehicles) (2) Suitable loading of vehicles to increase the operation speeds and efficiency of vehicles. (2) By obtaining construction materials from suppliers in the local area you can make a reduction in the distance travelled. (2) By more efficient driving. Changing gears at the correct revolution and keeping a reasonable constant speed. (2) The issues with this are the execution and certification of staff training; also it will be expensive to train a large number of staff and drivers and that will also cost further delays. (2) Sharing knowledge about alternative sustainable fuels (2) In the UK and Europe diesel fuel is mostly used for generators and equipment on site but there is an interest in using an alternative sustainable fuel. Generators that are fuelled by bio diesel or gas powered are less carbon concentrated and would cut carbon emissions by 25%. These generators powered by diesel fuel have been tested on construction projects in the USA and in Europe and have been successful. The issues with this are supply, biodiesel is not a fuel that is regularly used and there are few people who produce it. With the use of sustainable fuels there might be issues that will arise with health and safety, the impacts, reliability, and performance. As the cost of buying biodiesel will be cheaper the cost of hiring a generator that has been modified to use biodiesel will be more as there are few. All those actions have been taken and will continue running in the construction section until 2012. Many problems arising from the other side, like financial and many delays to accomplish those actions. We might not successfully resolve and achieve all the actions according to the policies but at least we can see some progress of the construction industry part involving the environmental aspects.

Globalization & Planet Essay

In our world today, firm evidences are very much needed to support claims and produce a sturdy foundation of concepts that were recently discovered by few a portion of the population. In connection to this, the role that scientists play in the discovery and confirmation of certain events is very crucial especially in terms of environmental issues because they are deemed to be the people who are knowledgeable of the technicalities and dimensions of the natural phenomena (Gott et al. , 2009). In dealing with these types of issues, it is believed that the knowledge and expertise of the scientists, researchers, and other experts must be put into consideration prior to the development of environmental policies (Gott et al. , 2009). This is based on the idea that the availability of concrete scientific evidence will enhance the integrity of the policy that is to be formed and will also save the stakeholders from investing time and monetary provisions to policies and actions that are not hinged on well-researched and scientifically backed up data (Gott et al. , 2009). Consequently, the importance of a having scientific evidence prior to the formation of environmental actions is essential in ensuring that all the possible pitfalls and counteractions for the study are provided. B. Is it better to prepare for the consequences of global warming rather than try to prevent it? As seen from the slide presentations of chapter 9, it is clearly depicted from this reference material that it is more important to prevent the occurrence of global warming rather than trying to rely on the idea that preparation for the consequences of this natural phenomenon is a better option (It is one planet, n. d). Although it is true that the occurrence of global warming is a natural phenomenon that will proceed on its own conditions, man should still do his or her best to accomplish ways that can lessen the speed of the reactions and minimize the possible amount of the detrimental effects on our mother Earth. At present, actions made by national leaders like Al Gore and government leaders of other developed countries will tell us that addressing the roots of the problem on global warming is still a better option than just sitting down and waiting for the effects to come and hoping that the pre-formed actions will suffice the need to prevent subsequent damages (It is one planet, n. d). People all over the world can lessen the utilization of carbon-based products, reduce the usage of technologies that emit substantial amount of pollution to our surroundings, and exhibit a global effort to lessen the consumption of materials that tend to damage the quality of the natural resources that are made available to us by nature in order to prevent the worsening conditions of global warming (It is one planet, n. d). C. Can you imagine a world without oil? Does it matter? In 1950s, a geologist named Marion King Hubbert predicted the bell-shaped trend on the production and consumption of oil products in the United States of America and by comparing his predictions to the present conditions, it will appear that he is right (Goodstein, 2004). According to Hubbert, oil production or oil supply in the USA will start to reduce by 1970 (Goodstein, 2004). Here also said that the worldwide supply of oil will also start to reduce by the year 2000 (Goodstein, 2004). In accordance to this, present data show that humans are using oil products at rate of about 25 billion barrels per year and by merging this data to the predictions of Hubbert and other experts, it can be said that we have about 40 more years to enjoy the benefits of oil (Goodstein, 2004). Based from these facts, it can be said that a world without oil is not far from reality and is actually about to happen in the near future (Goodstein, 2004). Hence, people should act now on the development of alternative energy sources in order to avoid pandemonium that is caused by the lack of material that will power our modern equipments (Goodstein, 2004). D. Are environmental issues an opportunity or a constraint for corporations? Corporations can look at environmental issues both as constraints and as opportunities depending on the way by which they handle the situation (Shah, 2002). In a report published in 2002 by the United Nations Environment Program, they said that there is an increasing disparity between efforts to save the planet and business projects (Shah, 2002). One specific example on the manner by which corporations utilized environmental issues as an opportunity is seen on the exploitation and harassment of the Nigerian people in order to push through with the oil extraction process in the said country (Shah, 2002). This event clearly shows the abusive power that can be manipulated by large corporations (Shah, 2002). In contrary to this, however, are the efforts made by the GE Company to develop green business, a venture that has enabled them to produce eco-friendly products (GE Company, 2010). Therefore, it lies in the hands of the owners of these big corporations on whether they will use their power to benefit or to harm the Mother Nature. E. Should the decisions at global conferences be made enforceable? By whom? Ultimate enforcement of decisions made on global conferences can only be done if majority of the participating nations have agreed on the idea that was raised and when a global pressing issue is the concern of the conference (UN, 2009). Consequently, it is the United Nations which is allowed to execute enforcement of these types of decisions and this is because of the fact that this organization is joined by majority of the nations in the world and is also authorized to carry out stipulations and solutions to issues on health, environment, and social concerns (UN, 2009). F. How does bring about a change in life styles in order to live sustainability? In order to switch to a sustainable way of living, a series of simple to complex efforts can be done by a person and these efforts are characterized by the alteration of the way by which one deals with his or her environment, changing the daily activities and avoiding bad habits, and overall promotion of responsibility to the things that are executed by the person (Ways of Wisdom, 2002). Specific steps that can be done in order to have a sustainable lifestyle include the promotion of resourcefulness, healthy physical work, and self reliance; not focusing on the short-term effects of monetary rewards but on the long-term plans, tapping natural resources in a positive way like backyard gardening and tree planting, stewardship for the environment, and valuing the importance of time and resources in order to avoid waste of time and efforts on non-important things (Ways of Wisdom, 2002).

The Most Controversial Plays of the 20th Century

The theater is a perfect venue for social commentary and many playwrights have used their position to share their beliefs on various issues affecting their time. Quite often, they push the boundaries of what the public deems acceptable and a play can quickly become very controversial. The years of the 20th century were filled with social, political, and economic controversy and a number of plays written during the 1900s addressed these issues. How Controversy Takes Shape On the Stage An older generations controversy is the next generations banal standard. The fires of controversy often fade as time goes by. For example, when we look at Ibsens A Dolls House we can see why it was so provocative during the late 1800s. Yet, if we were to set A Dolls House in modern day America, not too many people would be shocked by the plays conclusion. We might yawn as Nora decides to leave her husband and family. We might nod to ourselves thinking, Yep, theres another divorce, another broken family. Big deal. Because theater pushes the boundaries, it often evokes heated conversations, even public outrage. Sometimes the impact of the literary work generates societal change. With that in mind, lets take a brief look at the most controversial plays of the 20th century. Springs Awakening This caustic critique by Frank Wedekind is one  of hypocrisy and societys flawed sense of morality stands up for the rights of adolescents. Written in Germany in the late 1800s, it was not actually performed until 1906. Springs Awakening is subtitled  A Childrens Tragedy. In recent years Wedekinds play (which has been banned and censored many times during its history) has been adapted into a critically acclaimed musical, and with good reason. The storyline is saturated with dark, brooding satire, teen angst, blossoming sexuality, and tales of innocence lost.The main characters are youthful, likable, and naive. The adult characters, in contrast, are stubborn, ignorant, and almost inhuman in their callousness.When the so-called moral adults rule by shame instead of compassion and openness, the adolescent characters pay a heavy toll. For decades, many theaters and critics considered Springs Awakening perverse and unsuitable for audiences, showing just how accurately Wedekind critiqued turn-of-the-century values. The Emperor Jones Although it is generally not considered the best play by Eugene ONeill, The Emperor Jones is perhaps his most controversial and cutting-edge. Why? In part, because of its visceral and violent nature. In part, because of its post-colonialist criticism. But mainly because it did not marginalize African and African-American culture in a time when openly racist minstrel shows were still considered acceptable entertainment. Originally performed in the early 1920s, the play details the rise and fall of Brutus Jones, an African-American railway worker who becomes a thief, a killer, an escaped convict, and after journeying to the West Indies, the self-proclaimed ruler of an island. Although Jones character is villainous and desperate, his corrupt value system has been derived by observing upper-class white Americans. As the island people rebel against Jones, he becomes a hunted man -- and undergoes a primal transformation. Drama critic Ruby Cohn writes: The Emperor Jones ​is at once a gripping drama about an oppressed American black, a modern tragedy about a hero with a flaw, an expressionist quest play probing to the racial roots of the protagonist; above all, it is more highly theatrical than its European analogues, gradually quickening the tom-tom from normal pulse-rhythm, stripping away colorful costume to the naked man beneath, subordinating dialogue to innovative lighting in order to illuminate an individual and his racial heritage. As much as he was a playwright, ONeill was a social critic who abhorred ignorance and prejudice. At the same time, while the play demonizes colonialism, the main character exhibits many immoral qualities.   Jones is by no means a role model character. African-American playwrights such as Langston Hughes, and later on Lorraine Hansberry, would create plays that celebrated the courage and compassion of black Americans. This is something not seen in ONeills work, which focuses on the turbulent lives of derelicts, both black and white. Ultimately, the diabolical nature of the protagonist leaves modern audiences wondering whether or not The Emperor Jones did more harm than good. The Childrens Hour Lillian Hellmans 1934 drama about a little girls destructive rumor touches upon what was once an incredibly taboo subject: lesbianism. Because of its subject matter, The Childrens Hour was banned in Chicago, Boston, and even London. The play tells the story of Karen and Martha, two close (and very platonic) friends and colleagues. Together, they have established a successful school for girls. One day, a bratty student claims that she witnessed the two teachers romantically entwined. In a witch-hunt style  frenzy, accusations ensue, more lies are told, parents panic and innocent lives are ruined. The most tragic event occurs during the plays climax. Either in a moment of exhausted confusion or stress-induced enlightenment, Martha confesses her romantic feelings for Karen. Karen tries to explain that Martha is simply tired  and that she needs to rest. Instead, Martha walks into the next room (off-stage) and shoots herself. Ultimately, the shame unleashed by the community became too great, Marthas feelings too difficult to accept, thus ending with a needless suicide. Although perhaps tame by todays standards, Hellmans drama paved the way for a more open discussion about social and sexual mores, ultimately leading to more modern (and equally controversial) plays, such as: Angels in AmericaTorch Song TrilogyBentThe Laramie Project Considering a rash of recent suicides due to rumors, school bullying, and hate crimes against young gays and lesbians, The Childrens Hour has taken on a new-found relevancy.   Mother Courage and Her Children Written by Bertolt Brecht in the late 1930s, Mother Courage is a stylistic yet grimly disturbing depiction of the horrors of war. The title character is a cunning female protagonist who believes that she will be able to profit from war. Instead, as the war rages on for twelve years, she beholds the death of her children, their lives vanquished by the culminating violence. In a particularly grisly scene, Mother Courage watches the body of her recently executed son being tossed into a pit. Yet she does not acknowledge him for fear of being identified as the mother of the enemy. Although the play is set in the 1600s, the anti-war sentiment resonated amongst audience during its debut in 1939 -- and beyond. Over the decades, during such conflicts as the Vietnam War and the wars in Iraq  and Afghanistan, scholars and theater directors have turned to Mother Courage and Her Children, reminding audiences of the horrors of war. Lynn Nottage was so moved by Brechts work she traveled to war-torn Congo in order to write her intense drama, Ruined. Although her characters exhibit much more compassion than Mother Courage, we can see the seeds of Nottages inspiration. Rhinoceros Perhaps the perfect example of the Theater of the Absurd,  Rhinoceros is based upon a deviously strange concept: Humans are turning into rhinos. No, its not a play about the Animorphs and its not a science-fiction fantasy about were-rhinos (although that would be awesome). Instead, Eugene Ionescos play is a warning against conformity. Many view the transformation from human to rhino as a symbol of conformism. The play is often seen as a warning against the rise of deadly political forces such as Stalinism and fascism. Many believe that dictators such as Stalin and Hitler must have brainwashed the  citizens  as if the population was somehow fooled into accepting an immoral regime. However, in contrast to popular belief, Ionesco demonstrates how some people, drawn toward the bandwagon of conformity, make a conscious choice to abandon their individuality, even their  humanity  and succumb the forces  of society.
