Performance Assessment of Phase Change Materials Integrated with Building Envelope for Heating Application in Cold Locations

Phase change materials (PCMs) are increasingly investigated in the last years as successful many thermal energy storage applications. In building sector, PCMs utilised to improve efficiency by reducing cooling/heating loads and promoting renewable sources, such solar energy. This paper shows recent research works on integrating with envelope for heating purposes. The main PCM categories their characteristics presented, focusing types applied methods adopted incorporate elements mentioned, popular passive active incorporation techniques discussed. Lastly, contribution saving is discussed terms of analysed studies indicated that all could cold climates up 44.16% regardless techniques. Several conclusions recommendations derived from believed be a guideline further research.
