Essay On Energy Efficiency Of Building

728 Words3 Pages

Energy efficiency of building Among the biggest consumer of energy in countries with a high degree of urbanization and high standard of living are building. Building energy consumption mostly are from thermal and lighting loads especially office and hotel type building. Thermal and lighting load can be minimizing from architectural design and building dynamic behavior. Energy is mostly use for the cooling of building because of hot and humid tropical climate in Malaysia. A statistic show a building consume about 250kW/m2/year of energy of which about 64% is for air-conditioning, 24% for generate equipment and 12% for lighting. Due to the shortage of natural resources, energy costs are rising. Other than environmental impact, higher energy costs …show more content…

Daylighting optimize natural sunlight entry into a building to minimize the use of artificial lighting. Artificial lighting is produce by electricity. Energy efficient lighting is use of artificial light to receive the optimal level of light for the lowest energy investment. Glass dome UTHM mosque will be designed with a glass dome to maximize the penetration of daylight. In order to control the amount of light entering the prayer hall, and ensure optimum lighting level without glare, the dome will be equipped with automated blinds. It has about six different configurations that change depend on the position of the sun at particular time. It contributes to energy saving because it prevents heat from entering the prayer hall, at the same time it will save on electricity for lighting. Low e-glazing glass wall Low-emissivity glazing glass or low-e glazing glass is a type of energy- efficient glass. Low-e glazing glass is chosen because of its characteristic that will minimize the heat which is can absorb heat from the outside of the mosque. Indirectly, by using the glass wall, it will minimize the usage of electricity for lighting at daytime. Low e-glazing glass wall will reduce the amount of energy lost through the glass.

    Imagine a world where we have used up all of our nonrenewable resources and no longer have gas to power our cars, no coal to make energy, and no natural gas to power you household items. Well it might not be too hard to imagine, because it is predicted that in less than 75 years we will use up all of our natural gas, oil, and coal deposits. This is just one of many reasons that the government needs to put more funding into green energy. They not only need funding to find new sources of renewable energy but they also need to invest more in products that produce clean energy like solar panels, windmills, and turbines in dams. Climate change has been a center of attention for many years now, however it seems that very few changes have been made to slow or stop it.

    They are two crucial aspects to the topic of energy, but are not included by the UN. A determinant reason that millions of people across the globe have to resort to biomass to cook is that the cost associated with modern energy makes it less accessible (Birol, p.1). This unfortunate situation is due to many reasons. A key reason is that many of the resources required to install energy plants are disproportionally controlled by a few geopolitical actors. This causes large fluctuations on the commodity prices all over the globe, making not only modern energy, but also other basic human development targets, such as shelters and transportations less attainable (Regnier, p.2).

It is very important as it helps to discover and ascertain new ways of conserving energy and ensuring energy efficiency of building components. Building developers, construction engineers are increasingly interested in creating more energy efficient reason, and for this purpose whole building energy simulation programs are being used to determine strategies that save energy and are cost effective. The most common way available to perform this building energy analysis is to implement building information modelling(BIM).
