Indoor Thermal Comfort Condition Analyzing In Naturally Ventilated Rural Houses of Dhaka Region, Bangladesh

Abstract

Thermal comfort has become one of the most pressing problems for people all around the world as global warming worsens. Bangladesh is an economically prosperous country with a large rural population living in substandard housing. Because these dwellings are in a tropical climate, they are frequently built from locally accessible materials such as mud, wood, bamboo, straw, jute stalk, grass, and so on. These materials are being replaced by brick, corrugated galvanized iron sheets, cement, concrete, and other materials as a result of increasing industrialization, technical improvement, and the improving economic status of rural people. The purpose of this article is to show the current thermal state of three types of naturally ventilated rural dwellings made of two different materials in the Dhaka region. As part of the study approach, a field investigation and a questionnaire survey were carried out. For the comparative examination of three types of dwellings, the existing values of the thermal comfort variables (temperature, humidity, and air velocity) were used. The analysis demonstrates that the double-heightened mud home is more pleasant in terms of thermal comfort factors and psychological reactions of the residents than the single-heightened mud house and C. I sheet constructed houses in a specific climatic location. This study intends to indicate that thermal comfort varies with different building materials and construction techniques in the same climatic situation, and so further research and material-based studies should be conducted to ensure the thermal comfort of rural residents.
