PCMs in building structure

Abstract

To reduce interior air temperature variance, the thermal mass of the building plays an important role. Conventional construction materials have limited heat storage capacity. Enhancing the thermal mass of building with PCMs improves the thermal inertia of the building and reduces interior temperature variance. Therefore, PCMs have significant potential in reducing interior temperature variance by applying them in building structure and components. In order to figure out whether a PCM will make a positive impact on building energy demand reduction, it has to be chosen carefully considering climate, lifespan, and type of material. Published research reveals that PCMs are fairly new to the market and the building construction practices, and if integrated within building structure and components have the potential to reduce interior temperature variance.
