Abstract:
Buildings account for about 40% of the global energy consumption and contribute over 30% of carbon emission, globally. A large proportion of this energy is used to achieve a thermal comfort within the building. To overcome this problem, green building elements in the construction reduce excessive energy consumption of the building. This paper reviews the effect of thermal comfort to electrical energy consumption through wall and roof material selection of each four mock-up green building in UniKL Green Building test-site. All the data are collected and descriptive analysis has been done to investigate the potential of green building as a method to reduce electrical energy consumption. Test results have been obtained and analysis has been performed to identify the characteristics of the four different materials of the wall (building envelope). The result from this study showed that mock-up green building that is built from green material could provide a better thermal environment than mock-up green building that is built from non-green material. The result also showed the amount of energy consumption could be reduced as less active cooling than the mock-up green building that is built from non-green material.
