The insulating paint with nanoparticles as a high-performance solution for the thermal and energy efficiency of buildings in hot areas

Abstract

The optimization of energy consumption has emerged as a prominent topic, drawing continuous attention from researchers across various disciplines, including the field of construction. In today's climatic and economic conditions, designers face a significant challenge in providing thermal comfort to building users through passive solutions, while simultaneously reducing energy usage and mitigating environmental impacts. The building facade, acting as a heat exchange surface between the interior environment and external climate, relies on several factors to perform efficiently. This research aims to investigate the thermal and energy performance of building facades in hot regions, specifically focusing on the application of insulating paint embedded with reflective nanoparticles. The study adopts an experimental approach, utilizing test cells to measure surface and ambient temperatures through thermal cameras, infrared thermometers, and thermo-hygrometers. Additionally, a numerical study employing the dynamic thermal simulation software "TRNSYS 17" complements the research, enabling an assessment of how facade surface properties influence the thermal behavior and energy efficiency of buildings throughout the year. The findings of the study reveal a positive impact of facade surface properties on the building's thermal performance and energy efficiency. The implementation of insulating paint with reflective nanoparticles emerges as a durable and effective solution, ensuring user well-being in hot regions while simultaneously reducing energy consumption for heating and air conditioning, and preserving the natural environment.
