The India Energy Security Scenario 2047 (IESS, 2047) suggests that residential air conditioners will increase from 21.8 million in 2017—about 8% of the Indian households—to approximately 68.9 and 154.4 million in 2027 and 2037, respectively. Also, the related energy consumption is likely to increase by a factor of four in the next two decades, according to the Indian cooling action plan. Therefore, the study of occupant cooling behaviour is essential to reduce and manage this significant electricity demand, helping to formulate and implement climate-specific cooling policies at the state level, and to adopt new low energy and low-cost cooling technologies at mass-market scale. The study aims to examine residential electricity consumption to investigate occupant behaviour by analysing the use of space cooling and mechanical ventilation technologies. Among the five climate zones in India, this study focuses on the occupant cooling behaviour in a warmhumid climate—using the village of Auroville as a case study—where summer and wintertime temperature can be 25-35 C and 20-30 C, respectively, with relative humidity 70-90%. For the analysis, electricity consumption data from 18 households (flats) are monitored for seven months (November 2018-June 2019). The results demonstrate the characteristics and complexities in occupant behaviour and insight on the operation schedule for different space cooling technologies in residential buildings.
