摘要

The study has been conducted to determine the thermal comfortability preference of different communities residing in naturally ventilated, reinforced concrete roof-structured buildings. The study includes three cities and surrounding areas located at different corners within the hot & humid climatic zone of India. The cities were so selected to include preferences of diverse communities from different races, cultures, food habits, clothing, lifestyle etc. There are also deviations in the pattern of rail falls and the occurrence of flood, geological and geographical conditions among these cities. The study clearly illustrates the differences in the preference for dwelling thermal comfortability among the communities. Simultaneously, globe, indoor and outdoor temperature data was also collected from the meteorological websites for the respective cities to draw the trends and determine the correlation. Linear regression was done to determine the thermal neutrality of people against the observed dwelling temperature to unveil zone-wise people’s preferences in terms of thermal comfortability. L1-norm principal component analysis highlights the patterns in the sensation during the hot and cold range of dwelling temperature for the communities of three cities. The findings reveal distinctive comfort thresholds of diverse communities and adaptive behaviours pertinent to the change in dwelling temperature at different locations within the same climatic zone. The findings will support the design and construction of residential buildings matching the dwelling temperature preference of the communities residing in these zones. The buildings will also reduce energy demand for operation of air conditioners and heaters.
