No, there aren’t ACs in IIT Hyderabad. Instead, there is a Radiant Cooling system that is equally good. In this cooling system, the walls and ceiling of the hostels have hidden pipes that have cold water running through them. The temperature of the water is controlled depending on the season and outside temperature. This system keeps the hostel rooms warm in winter and cool in summer.
To ensure judicious usage of water, recycled water from the rest of the campus is used in the radiant cooling systems. IIT Hyderabad takes water conversation very seriously and implements steps for the same.
