近几年,随着“以人为本”设计理念的提出,人们对住宅的舒适性要求越来越高,建筑能耗也随之增高。据统计,目前我国建筑能耗约占国民经济总能耗的25%左右,且呈上升趋势。另一方面,随着建筑能耗的增加和大量空调设备的安装,“城市热岛效应”日益严重,使环境日益恶化。我国建筑节能的重点应为:建筑本体的节能、采暖系统节能、提高照明和其他电器的效率、大型公共建筑节能。
In recent years, with the “people-oriented” design concept put forward, people are increasingly demanding residential comfort, building energy consumption will also increase. According to statistics, at present, China’s building energy consumption accounts for about 25% of the total energy consumption of the national economy, and is on the rise. On the other hand, with the increase of building energy consumption and the installation of a large number of air-conditioning equipment, the “urban heat island effect” is becoming increasingly serious, deteriorating the environment. China’s building energy efficiency should focus on: building energy-efficient, energy-saving heating systems, improve the efficiency of lighting and other electrical appliances, large public buildings, energy-saving.
