Energy recovery ventilation systems provide controlled ventilation while minimizing energy loss. They reduce the costs of heating ventilated air in the winter by transferring heat from the warm inside air being exhausted to the fresh (cold) supply air. In the summer, the inside air cools the warmer supply air to reduce ventilation cooling costs.
Ventilation is not an effective cooling strategy in hot, humid climates where temperature swings between day and night are small. In these climates, however, natural ventilation of your building (often required by building codes) will help to reduce your use of air conditioning, and attic fans may also help keep cooling costs down.
