摘要
公共建筑与居住建筑是建筑整体构成的主要部分。建筑物的节能,以外围护结构节能为主;外围护结构节能由屋面、外墙、外窗节能构成。由于现代建筑设计中,外窗占外墙的比例越来越大,导致通过窗户造成的能源损耗约占整体建筑的1/3~1/2。因此,窗户的节能性十分重要。窗户由窗框、玻璃组成,玻璃约占整体窗户的80%~90%,窗玻璃的隔热性能至关重要。阐述了太阳光辐射热能的性质及各种玻璃的节能性,着重介绍了镀膜玻璃及相关节能效果,对建筑节能设计有一定的参考价值。
Public buildings and residential buildings are two crucial parts of all buildings. The building envelope is important to the en- ersy efficiency of a building, which composed of the roof, exterior walls and windows. The proportion of window in the wall is increasing for modern design demands, so the energy loss through the windows accounts for 1/3-1/2 of the energy consumption in the entire building. Ener- gy-saving windows are especially important. Usually, except the window flame, the glass is about 80%-90% of the whole window. The glass insulation is crucial. The solar radiation heat and energy efficiency of various glasses are explained, highlighting coated glass.
