建筑节能是我国近年来大力提倡的项目,早在20世纪70年代,建筑节能概念就被正式提出。建筑节能的核心是减少建筑耗能,提高建筑中的能源利用效率。同时,建筑节能需以不影响人们感觉舒适度为前提,即室温冬季不低于18摄氏度,夏季不高于26摄氏度。 Building energy saving is a project vigorously advocated by our country in recent years. As early as the 1970s, the concept of building energy saving was formally put forward. The core of building energy efficiency is to reduce building energy consumption and improve energy efficiency in buildings. At the same time, building energy conservation needs to be based on the premise of not affecting people’s feeling of comfort, that is, not less than 18 degrees Celsius in winter and not more than 26 degrees Celsius in summer.
