For PCM applications in buildings, in order to cover a wide range of temper- atures for thermal comfort, using multiple PCMs is better than a single PCM. It can deliver that all PCM-based configurations had a lower DF in contrast to concrete and cement block samples, as shown in Figures 14 and 15, respectively.
