Abstract

The article focuses on evaluating the thermal properties of silica aerogel as an insulating material to enhance building energy efficiency in hot, arid climates, specifically Cairo, Egypt. Using numerical simulations via Autodesk Ecotect Analysis, the study investigates the effects of silica aerogel’s thickness, thermal conductivity, density, and specific heat on the energy performance of double-glazed windows. Results indicate that thickness (optimal at 5 mm) and low thermal conductivity (0.014 W/(m·K)) significantly reduce heating demand by 63% and cooling demand by 15%, while density and specific heat have negligible impact. The findings suggest that optimizing these parameters in silica aerogel glazing systems can substantially improve building energy savings in hot, arid environments.
