Simulation analysis of lightweight buildings Integrated with PCM in exterior building walls in hot climatic conditions

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.
