Experimental works based on active and passive thermography for measuring the thermal resistance of building walls

Abstract

This study presents the experimental part of RESBATI project. Several measurements based on active thermography were launched on a real Internal Wall Insulation. Three estimation processes proposed by project partners were applied in order to estimate the thermal resistance of this wall and its uncertainty. Moreover, the influence of some parameters (as applied heat power, convective heat transfer coefficient …) on estimation capability were also discussed. Besides, a two-week passive measurement was performed to compare with active method.
