The increased energy usage in buildings and infrastructure indicates that alternate means must be adopted to improve efficiency, conserve energy, and to operate the buildings with sustainable means. The energy demands must be reduced to develop energy efficient buildings for the future, without compromising the thermal and visual comfort level and performance of the building. For the buildings, energy efficiency can be achieved by using appliances of less wattage, improved architectural technique, and modified construction methodology. The energy analyzing software eQuest was used to simulate the building to meet the occupants’ thermal comfort and lighting software DialuxEvo was used to simulate the interior of rooms for achieving the visual comfort in the building. The exact architectural design, orientation, and required weather files were used to introduce energy efficient and sustainable design in the building. An attempt to increase the energy efficiency of one of the academic buildings of our college considering daylight, thermal comfort, and visual comforts as the main factors was done. A design for installation of solar PV array on the roof of the building is also suggested to cut down the energy consumptions and cost savings.
