Urban Heat Island Mitigation via Cool Roofs and Blue–Green Corridors
Faculty of Economics at Sriracha , Sriracha Campus
Details
In response to intensifying heat waves, the project mitigated the campus urban heat island through combined measures: high–albedo cool coatings over 110,000 m² of rooftops, extensive green roofs on key halls, and connected blue–green corridors that channel airflow and cool surfaces. Shade canopies and drought–tolerant species were selected for optimal evapotranspiration, irrigated with reclaimed water.
Researchers deployed 32 microclimate stations logging surface/air temperatures, heat index, and air quality, paired with user heat–perception surveys via a mobile app that recommends cooler, safer walk–bike routes during peak heat. Legacy buildings received insulation and passive ventilation upgrades to curb air–conditioning dependence.
After one year, roof albedo rose from ~0.35 to ~0.65, cutting surface temperatures by 9.4°C and hallway air temperatures by 1.8°C; campus Cooling Degree Days decreased by 12%, cooling electricity fell by 16%, and heat–related incidents during outdoor events declined markedly. The project advances SDG 11 and SDG 13 with co–benefits to SDG 3, and fulfills 2025 indicators 96, 210, and 111.
