Phase change materials (PCMs) can be used for thermal energy storage and temperature regulation during phase change, and have broad application prospects in energy-efficient use and energy saving. The compatibility between traditional phase change materials and building materials is too bad to combine in building energy conservation. Therefore, the new phase change materials have become a research focus in the field of phase change energy storage in buildings. In the paper, the research progress of phase change materials in recent years and the optimization and application of passive building energy-saving are reviewed.

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.

Phase change method is one of the efficient approach in resolving energy problem for solar energy storage. However, phase change materials seriously affect the heat storage system with low heat releasing and absorbing rate for poor thermal conductivity performance, which result in an inefficient thermal energy storage technology and uncertain economic perspective. In this paper, we prepared dual-functional phase change nanocapsules based on n-octadecane core and polypyrrole shell. Polypyrrole was employed to enhance the electric conductivity and thermal conductivity. The nanocapsules was characterized using Fourier transformed infrared spectrophotometer (FTIR), field emission scanning electron microscope (FESEM), differential scanning calorimeter (DSC), thermal gravimetric analyzer (TGA) and infrared thermal imaging. The results shows a good thermal behavior and high latent heat of 81.99J/g. The dual-fuctional phase change nanocapsules can be expected with a prospect of future profits in energy storage technology.
