Analysis of Thermal Environment Improving Effects of Green Curtain in Summer†

In order to solve the limitations of horizontal thermal environment improvement, this study compared indoor and outdoor a building in summer according presence or absence green curtain, vertical greening method. 2021, air temperature, relative humidity, wind speed, shortwave longwave radiation were measured at central point inside grass field outside determine human sensation index, PET UTCI. As result, curtain showed an average 1.6°C cooler temperature during daytime, but it did not have effect night. For higher humidity indoors by 5.6% 1.0% daytime night, respectively. Wind speed was 1.4-1.8 ms−1 1.4-1.5 outdoors on respectively, showing high value regardless whether installed. The mean radiant reduction 4.7°C UTCI, reduced about 1/3 level, 2.1°C, UTCI 1/6 1.1°C, daytime. However, no effects appeared landscape planning, can effectively modify summer.
