Influences of Exterior Windows on Heating and Air-Conditioning System Energy Consumption in Residential Building

Abstract:

The energy consumption of a typical design of a building in Lanzhou was simulated by the software DeST-h to gain the changing regulation of rooms load index with different window-wall ratio, shading coefficient and the heat transfer coefficient. Research shows that the optimal window-wall ratio is 0.5 in the south orientation. In the other orientations, the smaller radio of window-wall could assure less energy consumption.
