Lawn covered earth surface has passive cooling effects and mitigates the hot environment in summer with its evapotranspiration mechanism. Soil covered roofs might decrease the cooling-load of buildings. Quantitative investigation of hygrothermal characteristics of lawn and soil surfaces is indispensable for the utilization of these effects. Eight test pieces, therefore, of lawn and bare soil surfaces have been observed to identify their hygrothermal characteristics since August of 1995 on the roof of a four-story building. Equivalent thermal resistance of lawn, volumetric soil water content and convective heat transfer coefficient of lawn and soil surface were obtained from the measured data in a long term experiments. Significant results predicting evaporation rate from the lawn surface with covered soil were shown in certain accuracy.
