In this study, the viability of passive cooling in residential spaces within the temperate climate of Kutch is examined using standardized adaptive comfort criteria. Ventilation-based free-cooling is identified as an energy-efficient cooling method. To maintain comfortable room temperatures and reduce energy consumption for mechanical ventilation, variable airflow rates are necessary when using ventilation for cooling. Consequently, free-cooling relies on the availability of cooling potential and appropriate airflow control mechanisms. The research focuses on the effectiveness of night ventilation techniques in the hot-dry climate of Bhuj, Kutch, for residential buildings. The study evaluates the impact of various natural ventilation approaches on the indoor thermal environment of Bhuj homes, using data from a comprehensive field experiment. Thermal performance measurements were taken from a corner terrace house in Bhuj to determine the efficiency of free cooling ventilation as a passive cooling strategy. The experiment compared four configurations: no ventilation, full ventilation, daytime ventilation, and night-time ventilation. The findings indicate that night ventilation offers improved thermal comfort for residents in Bhuj, Kutch, and has a significant impact on the results.
