Free Wind
Passive cooling for all
Free Wind is a passive cooling device designed to improve thermal comfort in slums and urban public spaces without relying on electricity. Inspired by ancient wind catchers and modern eco-coolers, the system channels and compresses natural airflow into indoor spaces, reducing interior temperatures in a sustainable, affordable way.
In 2015, 2000 lives were claimed in India, 1000 in Pakistan and many more across the world. Heatwaves are projected to occur at higher frequency, longer durations and are expected to be more intense in the future. Populations that perish in highest numbers were the very poor and elderly with lack of access to relief. Our project aims to provide relief at the lowest cost possible to reduce future heatwave related deaths.
Free Wind utilises the compression of air to produce air of a lower temperature, channeling it through the house in a constant cycle. It was inspired by the wind catchers in Iran as well as the Eco Cooler from Bangladesh. It functions as a cooling system utilising passive cooling methods while conserving the environment.
Free Wind employs modularity in design allowing it to be expandable and placed in many different environments from a small window, a large wall and even a tall chimney. To ensure it’s sustainability and responsibility to the environment, it uses Origo, a cornstarch based bioplastic, eco-friendly and 100% biodegradable. When the material wears out over time, Free Wind can be recycled.
