Examination of comfort by the thermal environment measurement and the subjective experiment on 3 different parts of a green roof

Abstract

The thermal environment measurement and the subjective experiment were made at 3 places (on the lawn, on the asphalt-paved path, under the wisteria pergola) on a green roof to clarify the physical and psychological quantity of the roof. Consequently, it was shown that the form of greening effect physical and psychology quantity except for winter. In summer, temperature and glove temperature under the pergola were lower than those on other two places and the test subjects also declared that it was cooler under the pergola than on others. Comfort zone was simulated as an area within crossed points made by a second regression line and the neutral axis of air temperature or globe temperature respectively. The zone by the pergola was wider than by the lawn and the asphalt.
