Résumé

India’s building energy consumption is increasing astronomically. The subcontinent does not have custom-made thermal comfort standards. Indian building environments are designed in accordance with the ASHRAE Std-55, which is not validated in India or on Indian subjects who are quite in contrast culturally with their western counterparts. There is little work done in this field in the last 26 years, leaving much to be done. The National Building Code of India (NBC) specifies two narrow ranges of indoor comfort temperature (21-23-26°C) irrespective of the building type or location. We are therefore conducting a thermal comfort field study in twenty office buildings in Chennai and Hyderabad for 13 months during 2012- 2013. Observing standard protocols, we collected 3045 sets of data involving 1942 subjects so far. On analyzing the first ten months of data, we obtained a comfort temperature of 27.1°C for Chennai and 26.0°C for Hyderabad in AC mode. It also returned a comfort band of 20.1–34.4°C for Chennai, while Hyderabad’s is 21.8-31.4°C in AC mode. This is much wider than that of the NBC, necessitating its revision. All the buildings surveyed except one were forced to run in naturally ventilated (NV) mode for two hours daily due to power blackouts. Thermal adaptation in NV mode was seriously hindered by several design deficiencies, mostly limiting the adaptive operation of windows. This resulted in lower thermal satisfaction in NV mode.
