science ☀️ Rainwater roofs could fight extreme heat waves
New research from The University of Manchester modeled a system that sprays harvested rainwater onto buildings during hot weather. This study used Tokyo as a case study and found that cooler roofs transfer less heat into structures. These effects could help reduce urban temperatures, cutting the number of heatwave days overall. Researchers suggest this provides a practical way to lower energy demand and urban heat. This approach also helps reduce extreme urban runoff. 💧
