CoolAnt Beehive – Passive cooling innovation from India

The Beehive is a modular, electricity-free cooling façade developed by Ant Studio in Delhi, India. It utilizes a terracotta beehive structure and recycled water to achieve evaporative cooling and natural ventilation. In a test at the Deki Electronics factory, the system reduced indoor temperatures from 42°C to 36°C and lowered airflow from 10 m/s to 4 m/s, offering a cost-effective and energy-efficient alternative to traditional air conditioning.

• The Beehive is a modular façade unit that provides cooling without electricity or the emission of gases with high global warming potential, utilizing a combination of natural ventilation and evaporative cooling. Its design features cylindrical terracotta pots through which recycled water at room temperature runs to cool passing hot air.
• Testing at the Deki Electronics factory in India demonstrated that the Beehive installation reduced indoor temperatures by 6°C, dropping from 42°C to 36°C on a hot day. Additionally, it reduced airflow around the site from 10 metres per second to 4 metres per second to improve thermal comfort.
