随着我国国民经济的快速发展,人民的生活水平和居住条件不断改善,住房消费者对住宅的观念、环境、功能、档次等多方面都提出了更高的要求。建筑节能是指在保证居室热舒适环境条件下,通过技术进步、合理利用、科学管理和经济结构合理化等途径,把建筑在长期使用中的采暖能耗降下来。建筑节能不仅可以节约能源,获得明显的经济效益,而且可以提高室内热环境质量,减少环境污染,具有明显的社会和环境效益。建筑节能一方面是指建筑本身的节能,另一方面与城市的综合环境、气候条件、总体布局,建筑物的朝向,外围护结构保温、隔热的性能,门窗质量等综合因素有关。
With the rapid development of the national economy in our country, people’s living standards and living conditions have been continuously improved. The housing consumers have put forward higher requirements on residential concepts, environment, functions and grades. Building energy conservation refers to lowering the heating energy consumption of buildings during long-term use through technologies such as technological progress, rational utilization, scientific management and rationalization of economic structure under the conditions of ensuring thermal comfort of the living room. Building energy efficiency can not only save energy, access to significant economic benefits, but also improve indoor thermal environmental quality, reduce environmental pollution, with obvious social and environmental benefits. On the one hand, building energy conservation refers to the energy saving of the building itself, on the other hand, it is related to the comprehensive factors such as the city’s comprehensive environment, climate conditions, overall layout, the orientation of the building, the insulation of the external envelope, the performance of thermal insulation and the quality of the windows and doors.
