Based on state-of-the-art technology solutions developed by Free Running Buildings for markets in the Far East, FREECOOL+ will be adapted to provide a lower-cost, efficient, zero-energy alternative to mechanically ventilated air conditioning systems.

FREECOOL+ is an innovative, passive air-cooling system housed within a roof-mounted wind tower. It uses heat pipes and a cold sink to continually cool incoming air to provide fresh air supply and cool environments by up to 15 degrees Celsius.

The resulting impact entails far-reaching social, economic, health and environmental benefits. In the short term this will include delivering heightened thermal comfort and optimum air quality in schools, healthcare facilities and office complexes in Kenya’s refugee camps. In the medium term, it is expected that uptake of the commercialised product will extend to Kenya’s dominantly rural population and enter the hospitality and tourism industry. Longer term, the uptake of passive technology and development of this market in Sub-Saharan Africa, will reduce CO2 emissions and align with Kenya’s commitment to cut greenhouse gas emissions by 30% by 2030.
