The performance of the building shell has a significant effect on the cooling and heating load of the
building. One of the things that have a significant effect on storage and improving thermal comfort
conditions are PCMs because they can store thermal energy in both tangible and latent thermal energy
in materials. The thermal performance of the building shell can be improved by using PCMs. The
purpose of the present study was to examine the effect of using four types of PCMs with different melting
temperatures and specific latent heat in the external and internal walls of the building on reducing the
energy consumption of the studied building in Tehran climate using building information modeling and
Energy Plus software. The simulation results show a significant reduction in heat transfer using PCMs
in the building shell and a reduction in annual energy consumption of up to 3.97%.
