Summary

Recent changing nature of climatic events, especially temperature rise, is making dwelling units of Bangladesh inappropriate, for both current and predicted climate of the future. This paper, based on a recently concluded research, at the Bangladesh University of Engineering and Technology (BUET), aims at presenting the current environmental condition, or combination of thermal comfort variables (temperature, humidity, and air velocity), in rural housing of Bangladesh, where more than 75% of total population lives. Investigation shows that the materials being used in rural housing are changing, with availability, affordability and technology transfer. New materials cause changes in internal conditions within these houses. With the objective of determining the current environmental condition in these houses, a field based investigation was adopted, to collect necessary base data for the research. Focusing on the Dhaka region, the results reveal higher indoor temperature values in the pre-monsoon period of the year, as households increasingly shift towards manufactured materials like corrugated galvanized iron (C.G.I.) sheeting, due to widespread availability, affordability and durability. Thus, in any predictions of future overheating, these rural houses need to be looked at critically, for ensuring indoor thermal comfort for rural occupants.
