Energy Efficient Nano Concrete Building

Abstract

Research on a wide array of topics is becoming more focused on energy use. Particularly in the built environment, a significant amount of energy is utilized, and as a result, there is a considerable increase in energy reduction. However, the reduction in energy consumption often results in a less comfortable indoor atmosphere for occupants of a building. The ambient temperature could be changed by the incorporation of Phase Change Materials (PCM) into the concrete as well as in building components. PCMs provide an increase in the ability of a wall to absorb heat (which leads to an increase in temperature of wall surface) and thus this latent heat is used to initiate the mechanism of phase transition of PCM . newlineThis research focuses on incorporation of PCMs in wall system as well as in concrete to emphasize the importance of maintaining ambient room temperature of building and thus saving energy consumption . The macro encapsulated PCM as well as micro encapsulated PCM of variable ambient temperature was selected and experimental analysis was carried out. In this analysis, microencapsulated PCM with MWCNT was incorporated in concrete in variable percentage combinations to investigate the impact of MWCNT with PCM on the mechanical properties of concrete and validation was done with respect to conventional concrete, moreover the thermal behavior of concrete was also investigated. Depending upon effectiveness of PCM, microencapsulated PCM (HS36) was incorporated into the exterior walls, due to presence of more surface area. The experimental investigation was carried to study and analyses the thermal behavior of PCM which holds the capabilities of maintaining the ambient temperature of 250 C to 280C of the building. newline
