Analysis of Nano Silica Aerogel Based Glazing Effect on the Solar Heat Gain and Cooling Load in a School under Different Climatic Conditions

Demand for energy-efficient school buildings, which form a major part of public is growing in Iran. Window insulation required to reduce the amount energy wasted through openings. This study investigates effect double-glazing with aerogel compared 3 mm glazing pane and window terms solar gain cooling load. The case studies are primary schools Yazd (hot-dry climate), Bushehr (hot-humid Zanjan (cold climate). Numerical simulations two-story performed calculate use system resulted reduction 73% about 33% loads simple window; if standard window, reductions 56% 16%, respectively gains consumptions. Also, allows 64% 27% when glazing. By using decreased by 62% 22% single layer
