Abstract
As urban areas and the number of people living in urban areas grow, it is important to assess different mechanisms for mitigating the resulting urban heat island . Two hardware scale models (16 ft2 footprint), identical except for their roofing material, were constructed and monitored to assess the impact of green roofs on urban temperature and humidity . During the daytime, indoor and outdoor temperatures of the green roof model were 4 .2°C and 0 .3°C cooler respectively than the black roof model . The green roof indoor temperature was 0 .7°C warmer during the nighttime . Humidity differences between the models were minimal likely because of the relatively small size of the models and the interaction with the ambient atmosphere . Differences between the models were most pronounced under calm, clear, warm, and dry atmospheric conditions . While further study is necessary, the results suggest that widespread implementation of green roofs could reduce the urban heat island effect
