Abstract: In Mumbai, India, around 42% of total population lives in slums and these houses lack adequate daylighting and air ventilation levels indoors. For this study, a slum house was selected from the dense urban fabric of Mumbai. The daylighting and CFD simulations were conducted to understand the feasibility of integrating a low cost chimney that would improve the indoor ventilation rates and illuminance levels. Various cases were considered to optimise the chimney location and height. The simulation results indicate that the 0.8 m high chimney in the centre of the house can increase the Air Change Rate (ACH) by 2 to 5 times and reduce the air temperature by 2°C to 4°C as compared to the existing case the addition of chimney also increased the room average illuminance levels from 75 lux in existing case to 300 lux.
