Abstract—In built environment, there is renewed interest towards the local building material, which is cost-effective, environmental-friendly, and best suited to the local climate. In this framework, the study will be emphasized the impact of local roofing materials on indoor thermal comfort of Bamboo house in a warm and humid region of Myanmar. In practice, Bamboo houses with different roofing materials were monitored with seven sensor points at outdoor and indoor to observe its thermal performance. By regarding microclimate conditions, the performance of different roofing materials on the indoor environment will be analyzed by statistical analysis based on the thermal comfort index. The result shows indigenous roofing material has less thermal conductivity impact on indoor thermal comfort than the other roofing materials. Moreover, the double roof, which is made of a combined layer of Dani and GI sheet, keeps the room with moderate thermal comfort for almost the whole day. The result of this study will propose suitable roofing material of Bamboo House and the required period to operate an air-conditioner with an extensive explanation to lead the reduction of Energy Consumption in further.
Index Terms—Bamboo vernacular house, indoor thermal comfort, local roofing material, tropical region.
