Apa de ploaie pentru răcorirea orașelor vara? Ideea cercetătorilor din Manchester

Researchers tested a rainwater collection system in Tokyo that automatically sprays buildings during extreme heat. The timing of spraying is more crucial than the amount of water used. This method could effectively reduce urban temperatures and energy demand, especially as climate change intensifies heat waves. The study indicates that cooler rooftops transfer less heat indoors, decreasing air conditioning needs. The findings suggest that strategic use of rainwater could mitigate the frequency and intensity of heat events in cities worldwide.
