The use of infrared thermography and thermo-aeraulic simulation to approach the real performance of existing buildings

Abstract

The objective of this study is to develop a relatively simple accurate method to represent the current energy state of an existing building to ensure its optimal rehabilitation. Firstly, infrared thermography was used to estimate the envelope thermal transmission coefficient (U). Secondly, the dynamic building simulations were realized through TRNSYS 17 to determine the studied building's energy performances. Each element of the envelope receives a measured U to represent the as is building condition. Finally, in this study, we have coupled CONTAM software with TRNSYS to evaluate the thermo-aeraulic behaviour of an existing building located in the north of Morocco.
