“…Among these, the use of phase change materials (PCM) in building envelopes for regulating indoor temperature has received considerable attention, due to their superior energy storage density and constant phase change temperature [3,4]. Previous studies [5][6][7] have demonstrated that incorporating PCM into building envelopes can significantly reduce the peak indoor air temperature by up to 14.51%, with a time delay of 71 minutes. These findings clearly demonstrates that PCM-enhanced envelopes have a positive impact on building energy management.…”
