西安市既有建筑节能改造技术与效果评价

总结了西安市既有建筑现状,结合具体工程,通过理论计算和检测,对既有建筑节能改造案例进行了研究分析,发现：西安市冬季采暖是决定能耗量的主要因素,节能的关键是围护结构的保温性能,对建筑的不同部位应分别采用相应的节能改造措施。

Existing buildings energy-saving renovation technology and effect assessment in Xi'an

The current situation of existing buildings was summed up.Research and analyses the case of existing building energy-saving renovation through theoretical calculation and testing with specific project.We found out that, the main factor of determine the energy consumption is winter heating in Xi'an,the key of energy saving is the insulation performance of the building envelope.Different position of building should introduce different energy saving renovation measure.
