Analysis of the thermal behavior of hollow bricks walls filled with PCM: Effect of PCM location

The drastic heat waves intensified by climate change have urged the cooling demand in the building sector. Therefore, thermal comfort in buildings has become a significant energy consumption issue. The building envelope is the primary separator between the conditioned indoor and the unconditioned ou...
