New position document outlines practical cooling strategies for homes, workplaces and cities to reduce heat-related risks and improve thermal comfort.
As prolonged and more intense heatwaves increasingly affect communities across India, the Indian Society of Heating, Refrigerating and Air Conditioning Engineers (ISHRAE) has released a new position document aimed at helping individuals, institutions and policymakers manage rising heat stress and improve thermal comfort.
The document, titled “Managing Heat Stress & Enhancing Thermal Comfort,” presents a science-based framework to reduce health risks associated with extreme heat while promoting sustainable and energy-conscious cooling practices.
Developed by ISHRAE’s technical groups specialising in healthcare, thermal comfort, passive cooling, evaporative cooling and safety, the report offers practical recommendations that can be adopted across homes, offices, public spaces and urban environments.
The guidance comes at a time when heatwaves are emerging as one of India’s most persistent climate risks, increasing pressure on public health systems, energy demand and urban infrastructure.
According to the recommendations, individuals are encouraged to limit exposure to direct sunlight during peak afternoon hours, maintain hydration and wear loose, light-coloured clothing. The document also recommends operating air conditioners at 25°C or higher in combination with ceiling fans to improve comfort while reducing electricity consumption.
For institutions, residential communities and building managers, ISHRAE highlights several passive and nature-based cooling interventions including cool roofs, improved ventilation, reflective building surfaces, shaded outdoor areas and tree plantation initiatives. The report also recommends establishing dedicated cooling rooms to support vulnerable populations during periods of extreme heat.
Speaking on the release, K. Raghavan, Society Chair of the ISHRAE Technical Committee, said heatwaves are increasingly becoming a recurring challenge for India’s cities and buildings, requiring practical adaptation measures that improve comfort while enhancing energy efficiency.
Beyond the technical recommendations, ISHRAE also announced continued industry engagement through initiatives focused on expanding participation in the built environment sector and supporting future innovation platforms for cooling and climate-responsive infrastructure.
With a network of more than 25,000 professionals and students across India, ISHRAE said the position document is intended to support long-term climate resilience planning across cities, businesses and communities.
The release signals a growing shift in India’s climate adaptation conversation—from emergency response toward long-term thermal resilience. While heat action plans have expanded in several states, integrating passive cooling, building design improvements and behavioural changes may become increasingly important as extreme heat events intensify.
The document also reinforces the role of cooling strategies that balance public health protection with energy efficiency and lower emissions.
