Experimental assessment of a phase change material in walls for heating and cooling applications

Abstract: The performance of a bio-based phase change material (PCM) was experimentally investigated in two identical full scale test huts exposed to the exterior environment. A layer of PCM enclosed in protective lightweight plywood sheets were added on the inside of 50 % of the walls (excluding floor and ceiling) in one of the test huts. Five months of data were recorded in 2013, from the end of February to the end of July. Several scenarios were tested for heating and cooling applications and clear differences were observed between both huts. The results show that adding PCM to building walls mitigates temperature variations and produces a time shift of wall temperature extremes. Data was also used to benchmark an EnergyPlus simulation model of the test huts.
