PCM Integrated hollow brick composite as building envelope material for efficient thermal management in buildings

Abstract

Energy is a very important prime mover for human activities in newlineday-to-day life and the conservation of energy through efficient usage is one newlineof the crucial factors for any nation s economic growth. In India, economic newlinegrowth, energy consumption, and increasing population rate are having strong newlinecorrelation with one another. The dependence on imported fossil fuels is newlineincreasing continuously in the recent years in India. Further, environmental newlinepollution due to the overindulgent consumption of fossil fuel is the main newlineconcern for all the countries in the world. The building sector plays a major newlinerole in energy consumption. It consumes almost 30% of the overall energy newlineproduction. In developed nations, this percentage has increased already to newlineabout 40%. The development and integration of energy-efficient technologies newlineand materials in the building sector are the ways to conserve energy in the newlinebuildings. The building envelope comprising of wall materials and glazing newlineconsumes more energy which can be modified by tailoring the construction newlinematerial with heat storage materials which reduces the solar heat gains into newlineroom and controls the indoor room temperature and helps in attaining the newlineenergy efficiency. Sensible and latent heat storage materials with high heat newlinecapacity are used to reduce the heat entry into the building. newlineThe Phase Change Materials (PCMs) based latent heat thermal newlineenergy storage system is one of the effective technologies available, which newlinecan be used to reduce the cooling energy demand. This is possible as the newlinemelting and solidification takes place by absorbing and releasing the latent newlineheat during phase transformation process in isothermal conditions. This newlinePCM-based passive cooling system provides renewable energy and has newlineminimum emission in the building sectors. newline
