Quantifying the Reduction in Cooling Energy due to Passive Cooling Techniques for Indian Cities

Arjun Desai, Prasad Vaidya | 2018


Past studies have quantified the potential of various passive design strategies to achieve thermal autonomy. Bhadra, Vaidya, & Sarraf (2017) have shown that for 60 cities in India, minimum thermal autonomy calculated by using the thermostat set point as the benchmark, is at 12% for night cooling, 75% for evaporative cooling, 28% for ground cooling and 32% for radiant cooling. This paper takes that approach further and quantifies the reduction in cooling energy due to three passive strategies, using the CIBSE method with Cooling Degree Days (CDD) for 60 Indian cities.
