Experimental Investigation on Aging and Energy Savings Evaluation of High Solar Reflective Index (SRI) Paints: A Case Study on Residential Households in the GCC Region

Energy-efficient retrofitting of building envelopes is necessary to reduce global carbon emissions and reach net-zero goals. Cooling energy demand-dominated countries in the GCC region require simple effective strategies sector loads. One such approach using high solar reflective index (SRI) paints retrofit roofs walls. However, hot desert conditions pose a barrier maintaining consistent radiative properties throughout their life cycle. To this extent, research limited region. The novelty work qualitatively assess aging characteristics SRI or cool estimate savings for application residential buildings. encompasses comprehensive lab, pilot, real-scale experimental studies combined with theoretical modeling dynamic evaluation. Dynamic simulations enabled determine time-dependent effect on performance retrofitted roof wall paints. A case study townhouse UAE showed annual 34% considering roofs, walls, window films. Aging reduction 36% 25%, respectively, walls during first 3 years. corresponding energy-saving reductions ranged from 31 44% white dark colors. Using initial values models overestimates saving by 10% per year. Considering effects, provides insights into paint potential energy, economic savings, CO2 four major cities
