Rooftop rainwater harvesting : Tokyo's rooftops could offer a new way to deal with extreme heat: collecting rainwater and using it to sprinkle roofs when temperatures rise.
A new study, "Optimizing the rainwater harvesting and roof sprinkling system to adapt to urban extreme heat," examined how rainwater harvesting and roof sprinkling could be optimized with machine learning to cool buildings, reduce air-conditioning energy use and address extreme heat.
