摘　　要：Rapid urbanization pressure and poverty have created a push for affordable housing within the global south.The design of affordable housing can have consequences on the thermal(dis)comfort and behaviour of the occupants,hence requiring an occupant-centric approach to ensure sustainability.This paper investigates occupant behaviour within the urban poor households of Mumbai,India and its impact on their thermal comfort and energy use.This study is a first-of-its-kind attempt to explore the socio-demographic characteristics and energy-related behaviour of low-income occupants within Indian context.Three occupant archetypes,Indifferent Consumers;Considerate Savers;and Conscious Conventionals,were identified from the behavioural and psychographic characteristics gathered through a transverse field survey.A two-step clustering approach was adopted for occupant segmentation that highlighted considerable diversity in occupants’adaptation measures,energy knowledge,energy habits,and their pro-environmental behaviour within similar socio-economic group.Building energy simulation of the representative archetype behaviour estimated up to 37%variations for air-conditioned and up to 8%variation for fan-assisted naturally ventilated housing units during peak summer months.The results from this study establish the significance of occupant factors in shaping energy demand and thermal comfort within low-income housing and pave way for developing occupant-centric building design strategies to serve this marginalized population.The developed low-income occupant archetypes would be useful for architects and energy modelers to generate realistic energy use profiles and improve building performance simulation results.
