Verification tests and numerical simulations were conducted in order to investigate the effect of misting technologies on reducing urban heat flux and saving energy. An apartment house was used as the test building in an investigation of three types of evaporative cooling techniques:" Rooftop spraying"," Veranda spraying" and" Spraying to the outdoor unit of room air conditioner". We confirmed that misting technologies had the effect of reducing surface temperature, air-conditioning usage time, improving air-conditioning efficiency and reducing the cooling energy consumption through the verification tests. And also, through the numerical simulations, we confirmed that the introduction of misting technologies had the effect of saving energy consumption for cooling by over 80%. As for an urban heat flux, numerical simulations also confirmed the effect of reducing by over 60%.
