This system uses a porous thermal wheel attached to the bottom of a wind tower. Thermal energy in the internal exhaust air is recovered to the incoming air. This system raises the incoming air temperature. By raising the temperature of the incoming air from the wind tower, adequate year round ventilation is maintained providing free heat.

Currently under final development, available in both retrofit to existing passive ventilation towers or as a low cost flat pack new system.
