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.
