ABSTRACT

The global climate changehas hada direct effect on the climaticweather patterns. Increased urbanisation and encroachment in green belts haveled to a rise in urban heat island effect, reduced urban air quality, limitation to storm water management and improved water run-off quality;at the same time contributing significantly for the degradation of biodiversity.The top covering of a building i.e.roofs which is directly exposed to solar radiation has been identified as the capable component that could contribute in providing substantial amount of energy savings and environmental benefit. This research focuses on comparison between electrical energy consumed to achieve stipulated indoor air temperatures and reduce the overall cooling load demands of a building by adopting alternative thermal insulation methods for roofs, rather than having a standard conventional flat roof.
