The frequent operation of air conditioners in both winter and summer in hot summer and cold winter regions has led to a significant increase in building energy consumption.Phase change materials (PCM),as excellent energy storage materials,can absorb and release heat in response to temperature changes.Based on this characteristic,their application in building envelopes can effectively reduce building energy consumption and improve the indoor thermal environment.This paper reviewed the research progress on applying phase change materials to building envelopes,analyzed and discussed the impact of four key parameters of phase change materials on the thermal performance of building envelopes,and finally looked forward to the development trends of applying phase change materials to building envelopes in hot summer and cold winter regions.
