Optimisation of passive design implementations at an urban scale in an Am climate zone

Nicholas Swedberg

Abstract: This paper utilised Chattogram, Bangladesh, as a case study city in an Am climate zone, a typology found throughout the Global South, in order to test the ability of passive design measures to mitigate the formation of the urban heat island and the resultant impact on the urban inhabitants of Chattogram. Cities in hot-humid climates represent an understudied urban typology, and given the rapid population growth of Chattogram, careful consideration needs to be given to urban development in the city. This study utilised open-source tools and data to create a workflow for testing these passive measures. The study found that, while effective in reducing dry bulb temperatures in the case study city, the impacts of high humidity meant that some health and well-being risks were not neutralised to as great an extent.
