The Pitch:
Poor ventilation is a major consumer of energy and a significant contributor to carbon emissions. In fact, poor ventilation wastes more energy than aviation uses. Aviation uses 3% of world energy. Household ventilation consumes over 5% and commercial ventilation consumes a further 5%.
The ReGen Ventilator is a wind powered ventilation system that extracts heat from stale air to heat fresh air entering a building. Unlike traditional heat exchange systems, it uses no electricity and is designed to retrofit easily to existing housing stock.
