the effect of pcms in the building shell on energy consumption storage

The performance of the building shell has a significant effect on the cooling and heating load of thebuilding. one of the things that have a significant effect on storage and improving thermal comfortconditions are pcms because they can store thermal energy in both tangible and latent thermal energyin materials. the thermal performance of the building shell can be improved by using pcms. thepurpose of the present study was to examine the effect of using four types of pcms with different meltingtemperatures and specific latent heat in the external and internal walls of the building on reducing theenergy consumption of the studied building in tehran climate using building information modeling andenergy plus software. the simulation results show a significant reduction in heat transfer using pcmsin the building shell and a reduction in annual energy consumption of up to 3.97%.
