The result shows that the shading coefficient of glass has more influence on air conditioning load and annual energy consumption than the heat transfer coefficient in Shenzhen. As a result, the air conditioning load can be 20% lower when the 3 mm ordinary clear glass is replaced by Low-e glass, and the building energ... 【基金】 建设部科技攻关项目(编号:032119)
