Collecting rainwater from rooftops and using it to spray buildings during hot weather could help cities cut air conditioning use, lower urban temperatures and lessen the impact of heatwaves, according to new research from The University of Manchester.

Cities around the world are facing rising temperatures, putting pressure on public health, infrastructure and energy systems. As people rely more on air conditioning to stay cool, energy demand increases and waste heat released from buildings can make urban areas even hotter.
Urban watering technologies are becoming important ways for reducing extreme heat in cities, but their use is often limited by the availability of water.
