Abstract
Temperature and heat fluxes were measured through a year at the greening and non-greening rooftop surfaces and verandahs (8 and 4th floors) of the building, of whichlight and thin sublayer were buried bamboo charcoal. There was a little daily change intemperature through a year on greening rooftop due to cut down the most heat flux. The temperature on the greening verandah was lower by 8 oC in daytime of mid-summer and higher by 3-4 oC at night of winter than on non-greening one, which controlled room temperature to be moderate at both seasons. Annual electric power consumption of greening floor was estimated to economize by about 15% , comparing with that of non-greening floor.
