Of Birds, Poets, and Architects

A Passivhaus is so well designed that it doesn't need a furnace for heating or an air conditioner for cooling. Because the house is so well sealed, it needs to be ventilated mechanically. That is done through a heat recovery ventilator, a device that pulls up to 80% of the heat from exhaust air and transfers it to the incoming, fresh air.
