As Industrialization has gained speed, Energy Consumption and given harm to the Environment has become one of the biggest global problems. Designing buildings and constructing them with conventional methods cause damages to the environment and increase energy consumption. Therefore in order to achieve best results to reduce the impact of buildings over the environment, a case study has been done with the support of informative literature and calculations. This literature has been carried out to show forth the works of various international designers with their observations, the case study has been carried out to compare two styles of buildings: vernacular and modern. The buildings chosen are the College of Engineering (main building) and the administrative building in the campus of Anna University, Chennai. It is found that the orientation of the buildings plays a significant role in the lighting energy of buildings. In general, for office rooms, illuminance provided by artificial lighting is 40% lower than that required. But sufficient lighting is provided by natural lighting with a daylight factor of 9%.
