N2 - Phase change materials (PCMs) contained in an insulated concrete block are tested in extremely hot weather of UAE to evaluate its cooling performance. An insulated chamber is constructed behind the block containing PCM to mimic a scaled down indoor space. The effect of placement of the PCM layer on heat gain indoors is studied at two locations, i.e., adjacent to the outer as well as the inner concrete layer. Inclusion of PCM reduced heat gain through concrete blocks compared to blocks without PCM yielding a drop in cooling load indoors. The placement of PCM and insulation layers adjacent to indoors exhibited better cooling performance compared to that adjacent to the outdoors. In the best case, a temperature drop of 8.5 % and a time lag of 2.6 h is achieved in peak indoor temperature rendering a reduction of 44 % in the heat gain. The research recommends to select a PCM with melting point higher than average summer night time temperatures placed adjacent to interior construction layers.
