Improving Roof Surface Temperature Control Using Heat-Reflective Inorganic Composition for Paint and Coating Application

Abstract

Abstract The increasing global temperatures and thermal islands have made cooling living spaces a pressing issue. Climate change and global energy use cause thermal islands. Greenhouse gas emissions and increasingly expensive and scarce energy supplies are causing disruptive global climate change. The use of energy, heat production, and greenhouse gas emissions caused by building air-conditioning increase the demand for cooling in developed environments. The dearth of sufficient electrical infrastructure for cooling buildings has increased summertime fatalities, including in places such as South Asia and Sub-Saharan Africa. Energy efficiency mitigates the rising cost of energy by reducing those emissions. The rise in surface temperature due to sunlight absorption needs to be reradiated to the sky, or it will conduct through roof spaces toward the ceiling and radiate downwards through insulation batts. Passive cooling technologies, which are environmentally friendly substitutes for extensions of aggressive cooling techniques can solve these problems. In this instance, we focus on the passive daytime radiative cooling of building envelopes and suggest that inorganic composition-based paints are well-suited for use in buildings worldwide. Selective absorption or scattering of light alters the appearance of the coating through inorganic composition. The present investigation focuses on incorporating various inorganic compositions into paint and reducing surface temperature after applying it to walls.
