Proper ventilation is essential to a healthy indoor living environment. Stale indoor air should be removed from the home and fresh outdoor air brought in. Many homes have natural ventilation called air leakage. Unfortunately this is inefficient and can led to attic condensation and ice dams. The stronger the wind blows the more ventilation you get. A high Performance home has a tight building shell and mechanical ventilation that is easily controlled by the occupant. How well is your home ventilated?
