【 摘 要 】

The Indian Green Building Council (IGBC) claims that India has the second largest registered green building footprint in the world. However, there is no evidence-based approach to ascertain the actual energy performance and occupant satisfaction vis-a-vis the building design and indoor environment. This paper seeks to apply a customised post-occupancy building performance evaluation approach for Indian green buildings (I-BPE), to evaluate the actual performance of a certified green housing development in the warm humid climate of India, from both technical and occupants' perspectives. Electricity consumption, environmental data, and occupant opinion of 29 flats are gathered and assessed over a period of one month in the monsoon season of 2018. Results show that flats with air-conditioning (AC) units tend to have slightly higher electricity use than those without; however, mean temperature and relative humidity measurements tend to be about the same and the level of perceived comfort is no different across the two groups. Building and occupant surveys revealed that storage facilities were insufficient, resulting in corridor space becoming a dumping ground, making it unsightly and unhygienic. The methodological approach developed in the study can be used for gathering empirical data on the actual energy and environmental performance of housing in India.
