Abstract
This study aimed to obtain fundamental data for quantifying the effects of wall greening panels in improving the thermal environment. First, moisture transmission parameters were calculated from evapotranspiration measurements of wall greening panels, which were measured using the weight method, and evaporation pressure deficit values, estimated from meteorological data. A simple equation was derived for estimating the evapotranspiration from the panels, and the heat balance on green panels was analyzed. As a result, the evapotranspiration values estimated using the simple equation agreed closely with the actual measurements and also with the latent heat-flux values calculated from sensible heat-flux and SAT measurements. Thus, the effects of evapotranspiration on wall greening panels in improving the thermal environment could be estimated quantitatively, using the equation and calculating latent heat-flux from heat balance.
