In this paper, a supermarket model located in Kathmandu is established by simulation software EnergyPlus. As one possible approach to improving the energy performance of the commercial building, this study develops an whole building energy simulation model to investigate the influence of two types of alternative walls – a insulated wall, a brick wall with 50 mm air gap and 4 inch additional brick wall on the energy performance of Bhatbhateni department store building at Krishna Galli, Lalitpur, Nepal. Single and double glazed glasses with varies thermal properties has been analyzed. This study finds that the 1 inch insulated external walls significantly improve the performance compared to the non-insulated wall. It is also found that the double glazed glass window models Envision and Reflectasol reduces the largest amount of energy. The results of this study can be used as basis data for estimating the potential energy saving with the replacement of alternative envelope (wall and window) under similar climate and orientation of the buildings.
