Analysis of the Effects of Climatic Factors on the Residential Buildings of Dhaka

Abstract

A large proportion of energy in built environment is used to ensure the comfort of the residents. And this comfort condition largely depends on the climatic factors such as, air temperature, humidity, wind flow, precipitation etc. When there is a situation of discomfort due to the climatic factors, it has a direct impact on the energy consumption rate of the residents especially on electricity consumption. Buildings account for about 40% of the global energy consumption and contribute over 30% of the CO₂ emissions. When designing buildings it is important to consider thermal comfort; designs should provide good thermal conditions based on energy-efficient technologies. In this research, a relationship between electricity consumption and climatic factors will be established to know if the climate factors have any effect on the increasing electricity bill in Dhaka city. Mainly climate data of one year will be collected at first and then to know the electricity bill in the same time period, a questionnaire survey will be conducted in major eight residential areas of Dhaka. The findings of this research will further help the architects to develop and implement the possible solution to decrease electricity consumption and increase comfort through architectural design in residential buildings.
