STUDY ON LOCAL MICROCLIMATE OF OUTDOOR DOMESTIC SPACES AFTER APPLYING FLOOR AREA RATIO AND MAXIMUM GROUND COVERAGE IN DHAKA CITY

Iftekhar Rahman, Abhijit Mazumdar

Abstract


Introduction: Urbanization in Bangladesh is a growing phenomenon. Dhaka is the capital of Bangladesh and has become known as one of the world’s megacities. This urban fabric influences the local microclimate of the respective areas. In 2023, the revised building construction rules with Floor Area Ratio and Maximum Ground Coverage introduced outdoor open spaces at ground level within the plots. Thus, various changes in the microclimate are expected, but very little research can be found on these issues. Aim: The purpose of this study was to analyze different configurations of outdoor domestic spaces at ground level with a view to the microclimate situation in the context of a planned residential area in Dhaka City. Furthermore, it compares the microclimate of the space configurations. Finally, it is expected to act as a guideline to help the architects and planners. Method: Microclimate-based computer simulation and statistical analysis were performed using ENVI-met, SPSS software. Varieties of building blocks (L, N, T, O, H, I, and U) were taken into consideration to see the impact. Result: Various building configurations were found to influence the local microclimate. Thus, at the end of this study, potential building configurations essential for a comfortable microclimate were suggested.
