A Comparative study of the thermal performance of mud and brick houses in Bangladesh

Abstract

Different building materials respond differently to climatic conditions due to their inherent properties. The thermal properties of building components such as walls, ceiling and floors together determine the energy consumption patterns and comfort conditions in an enclosed space. The aim of this study is to compare the thermal performance of naturally ventilated mud house and brick house, typical in the villages of Bangladesh. The objective is to search for affordable and energy-efficient construction techniques suitable for rural settlements. This is pursued by analyzing mean radiant temperature, Inter-zonal heat gain and comfort level within buildings constructed from traditional and modern materials. The study focus on single storied houses with pitched roof made of CI Sheet and wall materials are traditional mud walls and brick wall with plastered surface. The thermal behavior and comfort, the patterns of energy use of mud wall and brick wall are analyzed, compared and discussed. How a building envelope reacts to outdoor conditions through graphic illustration has been demonstrated and ways in which the research can be extended by the simulations using software has been showed. This research will contribute to the promotion of passive and low energy architecture towards a sustainable future.
