In the current global context of a climate and resource crisis, the research aims to look at the possibility of retrofitting these large-scale structures using passive stack ventilation strategies. These strategies aim to create thermally comfortable environments through natural ventilation and reduce active cooling load consumption and reliance on air conditioning. It is an investigation into the possibilities of retrofitting such poorly designed structures with cost-effective and straightforward stack ventilation strategies that require minimal intervention and can be carried out in already inhabited buildings. With a large percentage of homes in Hyderabad being mid-rise apartments, the study explicitly takes one such apartment currently under construction in the locality of Kismatpur, Hyderabad, to evaluate the performances of various stack ventilation strategies through CFD simulations and literature review. These studies are further optimized using formula-based calculators and comparative analysis of material and formal properties.
