Abstract
In order to evaluate the mitigating effects of urban heat island by wall greening, an experiment to characterize the evaporation effect of a greening system and to quantify its heat balance was carried out. At heat balance analysis, sensible heat flux is calculated using heat transfer coefficient estimated by measurements with SAT (Sol-air Temperature) meter. As a result, it is confirmed that wall greening has the mitigating effects of heat island due to the sensible heat reduction by consuming the latent heat by evapotranspiration. And it is able to evaluate the effects of wall greening system using evaporation efficiency as an index of evapotranspiration ability.
