A Comparison Study on Energy Consumption of Urban Residential Buildings in Different Climatic Zones

Abstract:

Built environment is determined by outside climate condition. There are a lot of important factors that influence building energy consumption such as building shape coefficient, insulation work of building envelope, covered area, and the area ratio of window to wall. In order to determine how building energy efficiency works in different climate zones, the variation rule of some aggregative indicators and building energy efficiency rates were analyzed by dynamic simulation. The results show that energy conservation potential which is brought by the decrease of builidng shape coefficient is the largest in hot summer and cold winter zone such as Shanghai, and the effect is mainly brought by insulation measures added to exterior walls.
