Effect of Thermal Properties of Building Glass on Cooling Energy Consumption of Buildings

Taking an office building in Guangzhou, China as example, the building environment simulation software DeST-c is used to study the effect of thermal properties of building glass on the cooling energy consumption. The results show that decreasing the shading coefficient of building glass can significantly reduce the cooling energy consumption. However, the heat transfer coefficient of building glass has little effect on the cooling energy consumption. The mechanism of the reduction of cooling energy consumption caused by the decrease of the shading coefficient is also discussed through hourly analysis on the cooling energy efficient rates all the year round.
