Abstract
This article aims to exhibit the potential of natural ventilation (nat-vent) as a passive cooling method within the low-income tenement units in tropical climatic regions using Mumbai as a case example. Furthermore, it also highlights the significance of interior design and optimized location of ‘active zone’ in delivering improved experiential nat-vent levels. A mixed-mode approach involving iterated design scenario generation based on housing survey, computational fluid dynamics (CFD) simulations for natural and mechanical ventilation modes (air-conditioning and ceiling fan) along with energy consumption modelling was implemented here to investigate the cooling energy-reducing potential of the nat-vent efficient indoor design. Results indicate that the selected interior design ‘scenario 1’ was capable of annual saving 364.43 kWh of cooling energy with a cost reduction of INR 2575.86. This study by formulating a method to assess the environmental-economic impact of nat-vent efficient interior design would aid the building engineers in paving a way towards the formation of sustainable design guidelines.
