近年来,随着建筑事业的发展,长沙地区的现代民用建筑日益增多,旧有建筑加装采暖空调迅速增加,人们对居住建筑的舒适性能提出了越来越高的要求。现代建筑的特点之一就是室内环境的人工气候化,即冬季进行采暖、夏季进行空调,显然,这将要消耗大量电能及热能。在实际设计工作中、节能却往往为建筑师所忽视。例如片面追求外型美观而采用大面积玻璃作为外围护结构,从而大大增加采暖空调能耗的实例并不少见。此外,由于安装制作不当,门窗密封性能低下,增大漏风热损失的现象亦很严重。
In recent years, with the development of construction projects, the number of modern civil buildings in the Changsha area has increased. The installation of heating and air-conditioning in old buildings has rapidly increased, and people have placed higher and higher demands on the comfort performance of residential buildings. One of the characteristics of modern architecture is the artificial climate of the indoor environment, that is, heating in winter and air conditioning in summer. Obviously, this will consume a lot of electric energy and heat energy. In the actual design work, energy conservation is often ignored by architects. For example, it is not uncommon for one-sided pursuit of good looks and the use of large-area glass as the external protective structure, thus greatly increasing the energy consumption of heating and air conditioning. In addition, due to improper installation and installation, the sealing performance of doors and windows is low, and the increase of leakage heat loss is also very serious.
