Build it Tight ... Ventilate Right!


Fresh Air Ventilation Calculations

We use a formula to find out how many cubic feet per minute (cfm) needs to be installed in your home on an hourly basis. The United States Environmental Protection Agency (EPA) states, "Ideally, new homes will be built to minimize leakage to control energy loss, improve comfort, and minimize the transport of moisture and pollutants through the building shell. These homes should then also have mechanical ventilation to remove pollutants generated in the home and provide outdoor air in a controlled manner. Whether a mechanical ventilation system makes sense in your existing home depends on the house, your existing heating, ventilation, and air-conditioning (HVAC) system, and the changes you have planned.".
