Commercial buildings have high energy intensity,and analyzing their influencing factors is an important foundation for promoting energy efficiency in commercial buildings.This study investigates the design parameters of typical commercial buildings in Shanghai,including floor areas,number of floors,body type coefficient and window-to-wall ratio,etc.,with the consideration on the form of cooling and heating sources as well as lighting power density.Sensitivity analyses using energy simulation software and orthogonal experimental method show that the following design parameters have significant impacts on annual energy consumption:lighting power density>comprehensive shading coefficient of external windows>building orientation>energy efficiency of air-conditioning system.The results of the study have important reference significance for the energy-efficiency design of commercial buildings in Shanghai.
