Green architectural technology has been focused since heat island phenomena became crucial. Urban Development Co. developed the thin roofing unit of which basis was 15 cm thick soil layer covered with lawn or orchid because the units were expected to have enough adiabatic capacity. We have tested the units for one and half years by measuring temperatures of soil layer, surface temperature of greens, water content of soil and evaporation rates from the units. In addition, climatic factors have been monitored simultaneously. As a result, the conductive heat transfer coefficients of the soil layer and greens were estimated to be 0.09-0.18 and 0.02-0.09W/m・℃, respectively and the evaporation rate was higher in summer and lower in winter. Therefore, the maximal adiabatic capacity of the units tested can be expected in summer due to increased insensible heat loss.
