METHOD OF IN-SITU MEASUREMENT OF THERMAL INSULATION PERFORMANCE OF BUILDING ELEMENTS USING INFRARED CAMERA

Specific and effective measures for international issues, such as prevention of global warming, energysaving, reduction of environmental loads, are urgently required.The improvement of the insulation efficiency of the house and the building is demanded as the part.For that purpose, it is also necessary to determine whether installed insulating materials have beeninstalled properly, and whether they can actually demonstrate the expected performance.On the basis of the results of various surveys, the infrared method was proposed as nondestructivein-site measuring method enabling simple measurements on site.Laboratory experiments and a verification experiment using an actual building at the site wereperformed for a method of measuring the thermal insulation performance of building elements in actuallarge structures by the infrared method (Hagihara et al. 2006 and 2007, Nakamura et al. 2006). Theresults confirmed that measurement accuracy can be sufficiently guaranteed.
