Wall insulation measures for residential building in Morocco: A case study in energy efficiency

Abstract

This work investigates the impact of insulation measures on buildings energy consumption using infrared thermography as a fast and non-destructive tool to evaluate their thermal performance in situ. In this context, we have used this tool to assess this technique effectiveness in evaluating the insulation application on a residential building located in the city of Tangier in Northern Morocco. An experimental protocol was carried out in order to diagnose the studied building before and after the insulation application. Firstly, the different external surface temperatures of this building are used to estimate the in-situ heat transmission coefficient (U). The obtained U-values were then used in the Thermo-aeraulic modelling of the studied building under different interior and exterior climate conditions using the TRNSYS18-CONTAM environment.
