With a increasing application of phase change energy storage technology in the fields of building energy conservation, refrigeration, and air conditioning, the shortcomings of traditional phase change materials (PCMs) have become important, which seriously restricts the development of phase change cold storage technology. Therefore, the new phase change materials have become a research focus in the field of phase change energy storage. The classification and characteristics of phase change materials are briefly described in the paper. In addition, the active building energy-saving are reviewed.

The building energy conservation has an important role in the energy field. Lightweight materials have been extensively used. By compositing the capric acid (CA) and lauric acid (LA) eutectic and using the expanded perlite (EP) as the matrix, a phase change material (PCM) was prepared and studied in laboratory. The mass fraction of this PCM reached at 60% through direct immersion for 24 hours. Differential scanning calorimeter (DSC) testing results indicated that the melting temperature of the PCM is 18.0°C, and the latent heat is 73.77J/g. From 1000 times cycling and heat-release characteristic test, this PCM was found to be stable well. After 2(wt)% graphite added in, solidification time of the PCM decreased by some 30%, the thermal conductivity improved. Application showed that the PCM has a positive effect on improving indoor environmental temperature.

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.
