Abstract
AbstractIn the present scenario with the rise in ambient temperature globally due to greenhouse gas emissions, cooling is one of the major concerns in residential and commercial buildings. Passive cooling techniques are one of the innovatory practices and technologies that, through natural means, provide buildings with comfortable environment. An in-house case study is carried out on passive cooling employing cool roof concept of radiative cooling, namely the application of THERMOROOF paint. A maximum drop of 2.2 °C in indoor room temperature was observed which eventually reduce the radiation heat gain by the occupants. Steady-state human thermal comfort is also modeled. The net heart transfer is found to be 53.2% higher in painted room in comparison to unpainted room due to reduction in painted room temperature.KeywordsPassive coolingTHERMOROOF paintThermal comfortHeat transfer analysis
