Energy, Thermal, and Economic Benefits of Aerogel Glazing Systems for Educational Buildings in Hot Arid Climates

The high cost of air conditioning during the summer makes it crucial to develop strategies reduce energy use in buildings, especially hot arid climates. Nanomaterial-based external window insulation is considered an effective method for achieving this goal. This research examines effectiveness using aerogel-based glazing systems combined with passive design techniques improve efficiency buildings regions. study presents various scenarios, including building orientation and aspect ratio, utilizing field measurements simulations aerogel-filled windows. two-phased. first phase compares two rooms aerogel conventional Aswan. new system made room 0.3–1.9 °C cooler. second simulated Egyptian Japanese School Aswan assess effects altering enclosed semi-open courtyard’s ratio. Results show that ratio can significantly consumption indoor thermal comfort. results reveal Scenario 1, which represents northern façade, could average temperature between 0.30 1.49 below base case (BC). 3, used on southern facade, reduced annual by 26.3% compared BC. Meanwhile, 5, a courtyard 2.40, save 25.7% more than 1. economic viability scenarios was also analyzed simple payback period analysis, 3 having second-shortest 4.13 years. By insulating exterior panes windows, proposes adopting make windows cost-effective ecologically sustainable.
