Performance of coupled novel triple glass unit and pcm wall

A PCM wall includes phase change material (PCM) as a heat storage medium. In the current project, the south façade of a test room was constructed using PCM walls that were made of (from inside to outside) insulation, brick, plaster (including PCMs), an air gap and a novel triple glazing unit (TGU). Although the annual behaviour of the PCM walls were investigated in the project, the current paper covers an evaluation of the performance of PCM walls in the summer only. The solar transmittance of the TGU decreased approximately 100% during summer compared to winter. There were no overheating problems observed for the PCM wall during the summer.
