Review of the Thermal Comfort and Energy Conservation Performance of Phase Change Materials (PCMs) In the Building Envelope

Throughout entire world, the electricity used to create energy demand and boost thermal comfort has risen significantly; policymakers and stakeholders are reinforcing policies to reduce building energy usage. The energy consumption is usually decreases by means of the Phase Change Material (PCM) inside the construction. It is very much important that PCM be used like Thermal Energy Storage (TES) because its increase in power density and low level temperature transition range. Various PCM materials, their temperature phase shift and PCM incorporation methods within residential buildings envelope will be elaborated in this paper. This PCM integrated gypsum board is highly acceptable in construction industry for the future due to its availability and high demand. Finally, all researchers agree that PCMs are a promising material in the construction industry for energy conservation and thermal fluctuation control, but there is a gap in the cost viability assessment and dependence on weather conditions of the area, which can further be studied in near future.
