当今世界面临的重大的问题是资源短缺,能源匮乏,所以相继提出可持续发展和技能减排的计划。近年来,我国每年所新建的约20亿m2建筑85%以上为高能耗建筑,现有的441亿m2存量建筑95%以上为高能耗建筑,并且单位建筑面积能耗是发达国家的2～3倍,建筑节能已经是迫在眉睫的头等大事。相对于现有普通建筑而言,节能型建筑科技含量更高,更好地利用了自然可再生能源,降低资源、能源的消耗或提高能源、资源的使用效率。我国目前已经将能源节约以及环境保护这两个问题考虑纳入到可持续发展的基本内容之一。
The major problems facing the world today are the scarcity of resources and the lack of energy so plans for sustainable development and skills reduction have been put forward one after another. In recent years, more than 85% of the newly built 2 billion m2 of buildings in our country each year are high-energy-consuming buildings. Over 95% of the existing 44.1 billion m2 of existing buildings are high-energy-consumption buildings, and the energy consumption per unit of gross floor area is 2-3 in developed countries Times, building energy efficiency is already a top priority. Relative to the existing ordinary buildings, energy-efficient buildings have a higher technological content and make better use of natural renewable energy sources, reducing the consumption of resources and energy or improving the efficiency of energy and resource use. At present, China has taken energy conservation and environmental protection into consideration as one of the basic elements of sustainable development.
