我国每年新增25亿平方米建筑,但大部分房地产开发商忽视门窗质量,使得门窗成为能源浪费的大漏斗。调查显示,在我国的三大主能耗中,建筑能耗占到总能耗的40%以上,而建筑通过门窗流失的能耗占到了一半。专家认为,我国应尽快制定节能门窗的标准,扶持企业加大科研力度,以降低建筑在使用过程当中的能耗。重“价”轻“质”门窗成建筑节能的“黑洞”门窗能耗在社会总能耗中的比重有多大?答案是惊人的,有调查显示,在我国,每年通过门窗流失的能量,占到建筑耗能的51%以上,占到了社会总能耗的20%。中国节能协会副理事长姚兵表示,建筑能耗、工业能耗和交通能耗是社会三大主能耗。建筑能耗占全社会总能耗的45%,通过门
China’s annual new 2.5 billion square meters of buildings, but most real estate developers ignore the quality of doors and windows, making windows and doors into energy funnel big funnel. Survey shows that in our three main energy consumption, building energy consumption accounted for more than 40% of total energy consumption, and building energy loss through the windows and doors accounted for half. Experts believe that China should formulate energy-saving windows and doors as soon as possible to support enterprises to increase research efforts to reduce energy consumption in the course of construction. What is the proportion of the energy consumption of windows and doors in the total energy consumption in society? The answer is striking. Some surveys show that in our country, the annual energy consumption The energy lost in windows and doors accounted for more than 51% of the building’s energy consumption, accounting for 20% of the total social energy consumption. Yao Bing, vice president of China Energy Conservation Association, said that building energy consumption, industrial energy consumption and transportation energy consumption are the three major energy users. Building energy consumption accounts for 45% of the total energy consumption of the whole society, through the door
