A new type of PCM layer integrated into an exterior building wall is to reduce the amplitude of the indoor temperature and maintaining the better thermal comfort for human beings. A numerical simulation has been carried out with and without integration of PCM in building walls. In this paper, the effect of different configuration of external building walls were studied and analyzed by the integration of PCM building walls. Using finite difference method, one dimensional transient heat transfer model was developed and solved. The indoor temperature was also analyzed for the summer and winter climatic conditions of Chennai city, India (13.1 Latitude and 79.9 Longitude) in the PCM and Non-PCM buildings. The building wall consists of clay brick with filled with PCM. The numerical simulation result shows that, PCM filled with clay brick wall improves the thermal inertia significantly. Location of PCM layer in the building wall is one of the important factors to reduce the heat gain in the building wall before it enters the room.
Nowadays the energy usage in the building sectors in the construction industry has been increased for increasing the cooling and heating loads of buildings. The renewable energy generation and incorporation of PCMs in building sectors attains around the world for energy savings. A passive cooling method with PCM integration in the building system is to decrease the energy demand of buildings. This process involves storing cool and heat energy and discharging it as needed. In this work, the ENERGYPLUS simulation has been carried for the PCMs incorporated in the constructed building wall in hot climatic weather conditions in India for considering the passive cooling method. It reduce the daily indoor temperature variation in PCM building throughout the year through absorption of cool energy in PCM during early morning hours without using mechanical energy devices.
