[Abstract] This study aimed to quantitatively assess the effects of wall greening，which is attracting attention as a countermeasure against the heat island phenomenon in cities，in mitigating the thermal environment by measuring the surface temperature and MRT of panels covered with vegetation and concrete walls (painted white). As a result, the surface temperature of panels was lower about 2～4°C without peak time, and MRT was also about 11°C lower at peak time. And then, by measuring the evapotranspiration from wall panels, and calculating the latent heat flux from the measurement data. The analysis showed that the evapotranspiration from the vegetation on the panels was about 4.1kg/m2 (4.1mm), and the latent heat flux from the panels was about 60% of the net heat emission. The study suggests that the effect of wall greening in decreasing sensible heat flux could bEquantitatively assessed.
