The heat wave in 2018 caused more than twice as many deaths in Germany as traffic accidents. “Nevo” is an infrastructure interface that provides water so that people can be supplied with drinking water and refresh themselves during heat waves. Nevo is connected to the local water supply via fire hydrants, where it can supply refreshment opportunities at 150 metre intervals. The energy supply functions autonomously thanks to a solar foil. Evaporative cooling occurs as soon as the fine water mist hits the heated skin. This ensures that the cooling effect on the skin lasts and that people can cool down during unacceptable temperatures. As soon as temperatures reach 30 degrees Celsius, Nevo lowers the ambient temperature with automatic sprays of water every three minutes. The residual water is collected and discharged to irrigate the surrounding urban greenery. Thanks to spray showers, we can continue to live carefree in overheated cities.
