Phase change materials (PCMs) have shown their big potential in many thermal applications with a tendency for further expansion. One of the application areas for which PCMs provided significant thermal performance improvements is the building sector which is considered a major consumer of energy and responsible for a good share of emissions. In this work, it is intended to review numerical modeling, experimental studies, prototype and full-scale testing, new applications, and other related developments of PCM-based products for the building sector. The review handles the basic elements where PCM is utilized or investigated for possible use such as mortars and bricks, concrete and brick walls, wallboards, roofs, floors, Trombe walls, and windows and facades. Newcontributions and applications are highlighted and relevant research and developmentsare analyzed and commented individually to ensure better understanding of the conceptsand the corresponding outcomes. At the end of each section the authors'personal opinionsare presented including comments on possible opportunities for further research. The con-clusion section provides the most important contributions and developments. It indicatesfuture research and development areas to improve energy performance, decrease energydemands, and increase the useful lifetime of the PCM products. The review shows the wide penetration of PCM in the building sector supported by intense research and development activities. As a result many certified PCM-based products are available in the market. It is hoped that this review can be of help to researchers, developing engineers, and architects working in the area.
