Sensitivity of energy performance to the selection of PCM melting temperature for the building located in Cfb climate zone

In the present study, optimization of PCM layer thickness and melting temperature to increase energy-saving potential office building located in eight cities Cfb climate zone was conducted using Fanger model. The sensitivity energy savings selection quantitatively analyzed a novel indicator average drop. Additionally, investigation effect real PCMs on performance as well economic environmental analyses were accomplished. results showed that with 2 cm reached highest values per unit thickness. revealed 22–25 optimum for whole resulted consumption reduction up 37.6%. analysis steadiness outdoor conditions affects temperature. 25-r demonstrated more efficient all cities. Overall, it concluded integration can be considered an economically environmentally feasible solution.
