我国建筑外围护结构保温性能很差,门窗气密性不良,造成冬季房屋室温较低,单位建筑面积采暖能耗却达冷天气温相近的发达国家的3倍左右。为减少能源消耗,改善居住热环境,根据建设部的安排,中国建筑一局科研所在中国建筑科学研究院物理所、北京市太阳能研究所和北京市钢窗厂的合作下,研究和采用了24项节能技术,在北京南苑建成了一幢有4个单元、面积为1760m~2的节能试验楼(以下简称节能楼),又在人工气候室和现场进行了多项建筑物理性能测试,并实测了不同单元的供热量,还分别按稳态法和动态法利用电算程
The thermal insulation performance of China’s building external protection structure is poor, and the airtightness of doors and windows is poor, resulting in low room temperature in winter, and heating energy consumption per unit building area is about three times that of developed countries with similar cold temperatures. In order to reduce energy consumption and improve the living environment, according to the arrangements of the Ministry of Construction, the cooperation between the Institute of Physics of the Chinese Academy of Building Research, the Beijing Institute of Solar Energy, and the Beijing Steel Window Factory has been studied and applied by the Research Institute of the China Building 1 Bureau. In the energy-saving technology project, a four-unit, energy-saving test tower with an area of 1,760m2 (hereinafter referred to as the energy-saving building) was built in Nanyuan, Beijing, and a number of building physical performance tests were conducted in the artificial climate room and on site. Measured the heat supply of different units, and also used the electronic calculation method according to the steady state method and the dynamic method respectively.
