This study selected an office building to test the demand of building cooling load in the hot summer and warm winter zone of China. Based on the hourly cooling load simulated by TRNSYS, sensitivity analysis was conducted on the building envelopes, and the exterior wall, shading coefficient and infiltration rate were retrofitted for assessing their thermal responses. Moreover, 26 retrofitting schemes were compared by energy and economic NPV evaluation. The results indicate that the optimal scenario is the scheme of the exterior wall slightly-retrofitted, infiltration rate highly-retrofitted and shading coefficient highly-retrofitted, which owns the maximum profit and an economical payback period.
