Abstract: This paper demonstrates the possibility of converting a public building from inefficient energy consumer into a net-zero energy building (NZEB). This task is achieved through cost effective energy efficient measures (EEMs) and integration of solar energy systems. Three scenarios that utilize the same roof area are proposed to convert the building into NZEB. The first two scenarios use only PV system with the second scenario that incorporates replacing current chillers with more efficient chillers while the third scenario combines both PV and solar cooling systems. The first scenario attains NZEB on annual basis only whereas the other scenarios achieve NZEB on both annual and monthly basis. The second scenario has distinct advantages over other scenarios with respect to energy saving, interaction with energy grids and economic consideration.
