节能门窗热工性能对建筑能耗影响的模拟研究

采用WINDOW和THERM软件模拟研究了典型节能门窗玻璃和整窗系统的热工性能，并结合杭州市全年气候条件，采用DeST软件模拟研究了配置不同节能门窗建筑的全年能耗状况.研究结果表明：门窗材料对于门窗热工性能有显著影响，选用低辐射系数的玻璃、热导率较小的木材等型材均可显著降低门窗的传热系数，而增加铝合金型材的厚度则增大了门窗的传热系数.不同材质、不同型号的节能门窗对杭州市建筑夏季制冷能耗和冬季采暖能耗产生不同影响，节能门窗实际选用时需根据当地气候条件具体考虑.

Simulation on Thermal Performance of Energy Saving Windows and Doorsand Its Influence on Building Energy Consumption

Thermal performance of window glass and entire windows and doors system was simulated by WINDOW and THERM software. Combined with the annual climatic data from Hangzhou, annual building energy consumption with different energy saving windows and doors was calculated by DeST software. The results show that materials of windows and doors play a significant role in saving energy.Wooden profiles with low thermal conductivity and Low E glass can significantly reduce the heat transfer coefficient, while thicker aluminum profiles increase heat transfer coefficient. Energy saving windows and doors with different materials and types greatly influence the energy consumption derived from air conditioning in summer and heating in winter in Hangzhou, respectively. Local climatic conditions must be considered in the choice of energy saving windows and doors.
