大气污染、雾霾天气,人们都认为是工业企业燃煤、汽车尾气排放等占了主要因素,却恰恰忽视了一项最大的污染源——门窗能耗。早在2003年,北京市建委就颁发了门窗的节能标准,北京市当一项硬性指标强行实施。而河北省却没有这样做,建筑门窗仍继续使用普通单玻铝合金窗和假冒伪劣的塑钢门窗来搞房屋建设。 Air pollution and hazy weather are all considered to be the main factors for coal combustion in industrial enterprises and emissions of automobile exhaust gas. However, one of the biggest sources of pollution—window and window energy consumption—has been overlooked. As early as 2003, the Beijing Municipal Construction Commission issued energy-saving standards for doors and windows, and Beijing implemented a hard target. However, Hebei Province did not do so, and building windows and doors still continued to use ordinary single-glazed aluminum windows and fake steel doors and windows for housing construction.
