摘　　要：建筑节能检测是保证节能建筑工程质量和实现节能减排的重要手段,主要包括对建筑用材料技术性能、施工质量及建筑的实际效能进行的检测和使用过程中的监测等。节能技术监测评价中心目前开展了对墙体材料的热工性能、建筑门窗、幕墙三性及传热系数、外围护结构热工缺陷等检测项目。通过分析建筑外围护结构热工缺陷的检测评价方法及现场检测的注意事项,对于新建建筑、既有建筑围护结构的热工缺陷检测工作起到了指导和规范的作用;检测现场采用红外热像仪普测及传热系数检测相结合的检测方式可以准确地反映围护结构缺陷面积、对建筑结构保温性能的影响程度及节能效果。The building energy conservation inspection is an important means to ensure the quality of energy conservation building projects and to achieve energy conservation and emission reduction,mainly including the technical performance of building materials,construction quality and the actual ef-ficiency of the building and the monitoring during use.At present,as to thermal performance of wall materials,building doors and windows,curtain wall and heat transfer coefficient,the thermal defect of peripheral structures and other inspection projects have been carried out by energy conservation tech-nology monitoring and evaluation center.Additionally,the inspection and evaluation methods of thermal defect inspection of peripheral structures in building and the precautions of field inspection are analyzed,which plays a guiding and normative role in the thermal defect inspection of peripheral struc-tures in new buildings and existing buildings.Most importantly,in field inspection,the combination of infrared thermal imaging and heat transfer coefficient inspection can be effectively and accurately re-flect the defect area of peripheral structures,the impact degree of thermal insulation performance on build structure and energy conservation effect.
