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.
