Study on Determination Methods of Thermal Parameters of Glass Curtain Wall under Certain Energy Consumption Goals

根据太阳光不同光谱对于采暖空调负荷和建筑采光的影响,建立了不同光谱特性下全年采暖空调照明能耗计算模型。利用该模型可以计算玻璃幕墙建筑能耗以及确定不同目标能耗的玻璃幕墙的热工参数,分析不同的玻璃幕墙的性能参数。模型更全面、准确地反映了玻璃幕墙热工性能参数对于建筑总能耗的影响,使玻璃幕墙的热工性能参数的选择更具有针对性和科学性。

According to the impart of different solar spectrum on the heating load of air-conditioning and building daylighting, calculative model of all-year energy consumption in different spectrum was set up. The use of the calculative model can calculate the building energy consumption of glass curtain wall, and analyze the thermal parameters of the glass walls with energy consumption of different targets. The model accurately reflects the impart of the glass curtain wall thermal performance parameters on the total energy consumption of the building, and makes the selection of thermal parameters of the glass walls more scientifie.
