A study on zoning regulations' impact on ventilation rate in non-conditioned apartment buildings in Dhaka city Conference Paper uri icon

abstract

  • Adequate ventilation rates are crucial to flush-out unwanted heat in non-conditioned apartment buildings in Dhaka city. The objective of this study was to identify an appropriate zoning regulation scheme for Dhaka's overcrowded residential area, which would provide better ventilation in apartment buildings without compromising the existing density. Four zoning regulation schemes (existing as well as hypothetical) were studied in terms of their impact on indoor ventilation. These schemes vary in terms of 'maximum buildable area' (80%, 70%, 60%, and 50%) and 'maximum building height' (6, 7, 9, and 11 stories) but the schemes are same in terms of density (90 DU/Acre). Ventilation potential in four different clusters of apartment buildings (modeled based on the four schemes) was examined using FLUENT and EnergyPlus. The study found that one of the hypothetical zoning regulation scheme (maximum buildable area = 70%; maximum building height = 7-story) provides better ventilation than the others.
