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

Main Influence

For well application in north of China, the optimal properties of phase change materials was screened out by comparing with the same adsorbing material – perlite in Lab conditions. Three main influence factors including adsorption time, experiment temperature and particles of expanded perlite were investigated for all sample of phase change materials. The results showed that capric acid is the optimal one of all samples due to its suitable transformation temperature at 30.1 oC and relative high adsorption proportion of 140% on the vacuum condition at 60 oC in 45 min. All experiments could provide useful data for the building energy saving of Tangshan district.
