摘要：

This paper discusses the cooling potential of three types of green roofs, insulated, uninsulated, radiant-evaporative, evaluated with test cells. Different rules and schedules were tested for irrigation, water movement through the radiant pipes, plenum fan operation, and cooling with outside air. Results indicate that on warm days with maximum outdoor temperatures below 32 degrees C the uninsulated green roof will perform better and on drier days up to 44 degrees C and a Wet Bulb Temperature below 24 degrees C, the green roof with a radiant system and evaporative cooling performs better. On very warm days with high maximum temperatures above 33 degrees C the insulated green roof and the insulated roof (non-green) perform better. Optimum zones for the green roofs are plotted on the Building Bioclimatic Chart.
