摘　　要：减小建筑玻璃对红外的透射率是减小玻璃遮阳系数从而降低空调能耗的有效途径。以广州地区一个简化的办公建筑模型为例,分别取玻璃对可见光透射率为0.5、0.6、0.7,利用DeST-c模拟计算了减小玻璃红外透射率对玻璃遮阳系数和空调能耗的影响。研究结果表明减小红外透射率可以在保证室内自然采光的同时显著降低建筑的空调能耗,节能潜力很大。Reducing the inferred transmittance is an efficient way to reduce the shading coefficient of the building glass and energy consumption of the air-conditioning system.Based on a simplified office building model in Guangzhou,the DeST-c code was used to study the effect of the inferred transmittance on the shading coefficient of the building glass and the energy consumption of the air-conditioning system for different visible transmittances（viz.,0.5、0.6、0.7）.The results show that the energy consumption of air-conditioning system could be significantly decreased while the indoor natural lighting could not be degraded by reducing the inferred transmittance of the building glass.
