Performance of Insulated Roofs with Elevated Outdoor ConditionsDue to Global Warming

Global warming is a serious condition when it comes to analyzing how to achieve thermal comfort by natural means. Withthe predicted rise of temperature from 2-4 0C, the probability of people turning to alternative thermal comfort options such as airconditioning would increase creating energy crises. Therefore, it is necessary to investigate building construction methods thatincrease thermal comfort. This study was aimed at evaluating the effect of expected global warming on thermal comfort relatedexpectations of people and to develop strategies that can assist to minimize the energy needed for thermal comfort especially intropical climates. The results suggest that construction of multi-storey houses with small foot print and insulated concrete slab asroof has the possibility of creating desirable micro–climates. The concrete slab roof provides the possibility of creating roof topvegetation which can significantly reduce the indoor temperature.
