Using Mist to Cool Down Urban Heat Island

Osaka City Waterworks Bureau is conducting on-site experimentation in Midousuji, the city’s main street, to lower a temperature of urban heat island.

Nozzles installed on top of buildings alongside of Midousuji street shoots out cool mists into the air. Using mist as a cooling method is highly effective in small areas. You may have seen it above lines at theme park on a hot summer day. About 2.4 tons of water will be consumed per hour to create a curtain of mist and it is expected to lower surrounding temperature by 2 degrees Celsius.

This experimentation will continue until mid-September to measure effectiveness of the cooling method.
