Thermal imaging survey of wooden buildings: Evaluation of two structural and technological solutions

The article highlights the possibilities of using the infrared thermography method to assess the energy efficiency of low-rise wooden buildings. The aim of the work is to study the influence of climatic conditions, as well as technological and design solutions on heat loss through wooden building enclosing structure and substantiate recommendations for improving the energy efficiency of such facilities. Experimental model facilities built in the cities of Murmansk and Petrozavodsk in 2020 are considered as the object of research. The objects were built using various structural and technological solutions of wooden house construction and using various thermal insulation materials. The results of external and internal surfaces examination of buildings enclosing structures using thermal imaging equipment are presented. The results of thermal imaging survey of experimental buildings were evaluated. Constructive solutions have been identified that insufficiently discolor the continuity of the thermal insulation circuit in enclosing structures. It is noted that the zones of heterogeneity of the thermal field for different structural and technological solutions of enclosing structures manifest themselves in different ways, which requires further consideration and research.
