CoolAnt Beehive – Passive cooling innovation from India

The Delhi-based Ant Studio developed the 'Beehive', a passive, modular façade cooling system that uses terracotta cones and recycled water to reduce indoor temperatures without electricity or harmful gases.

• The Beehive is a modular façade unit that provides air cooling and purification without using electricity or producing gases with high global warming potential. It utilizes a combination of natural ventilation and evaporative cooling, featuring a structure of cylindrical pots and terracotta cones over which recycled water at room temperature flows to cool passing hot air.
• Testing of the Beehive solution at the Deki Electronics factory in India demonstrated a temperature reduction from 42°C to 36°C (a 6°C difference) on a hot day. Additionally, the installation reduced airflow around the site from 10 metres per second to 4 metres per second, improving thermal comfort for workers in an environment where temperatures can exceed 40°C.
