Adaptability Analysis of Passive Building Energy Efficiency Technology in Hot Summer and Cold Winter Region

With the development of social economy, building energy consumption takes great proportion in whole society energy consumption. Building energy efficiency technologies especially passive building energy efficiency technologies should be used imminently. This paper researched on the adaptability of passive building energy efficiency technologies in hot summer and cold winter region with Ecotect software. Taking Chongqing, Wuhan, Changsha, Shanghai as the representative areas, this paper analyzed the adaptability of passive energy efficiency technologies which include passive solar heating, thermal storage wall, induced and night ventilation, natural ventilation, direct evaporative cooling,indirect evaporative cooling. Then, some passive building energy efficiency technologies are summarized that suit for the four representative cities through the year.
