Abstract:
Central Business District (CBD), located in the centre of a growing metro city, Ahmedabad, in a hot and dry climate, is the case study site. The on-site measurement and simulation method has been adopted to analyze the microclimate condition for current and future development scenarios of 2050 with increased Floor area ratio (FAR) and tree cover. To understand and quantify the heat stress on the human body produced by the surrounding meteorological circumstances, the Universal Thermal Climate Index (UTCI) has been used. The on-site collected data and simulation results provide a basis for studying the physiological and physical attributes related to OTC. The results suggest a significant impact of the sky view factor and the role of mean radiant temperature on OTC in all development scenarios. The shading due to the increased height of building stock imparts a favourable impact on thermal stress in outdoor urban areas.
