Thermal behaviour of concrete and corrugated zinc green roofs on low-rise housing in the humid tropics
This study focused on two types of roof spaces: concrete and corrugated zinc. Both green roofs were covered with short-lived productive vegetables throughout dry and rainy seasons, monitored by an infrared thermometer and a wet-bulb-globe thermometer. The results show that the green roofs in the humid tropics had significant thermal insulation capabilities, with a decline in thermal conductivity, of up to 57.1% from 1.99 to 0.85 W/(m K) in the concrete roofs, and 90% from 5.87 to 0.59 W(m K) in the corrugated zinc roofs. As opposed to non-green roofs, green roofs could reduce heat flow by up to 56% from 19.3 to 8.5 W/m2 in concrete and could reach 50.8% from 39.6 to 19.5 W/m2 in corrugated zinc. Green roofs over humid tropical dwellings are therefore useful for improving environmental microclimates, particularly in dense urban contexts.
