ERVs solve air tightness challenges in high performance homes

Whole home ventilation isn't restricted to new home construction.

Homes undergoing deep green remodeling can benefit from an energy recovery ventilator or heat recovery ventilator as art of the high performance upgrades.

At the 2016 AHR Expo, Barry Stephens, business development and technology director for Zehnder America, reviewed the need for mechanical ventilation in homes that have tight thermal envelopes.

Letting a home "breathe" isn't the answer any more, because too much energy is lost as well.

Stephens noted that mechanical ventilation can help overcome the shortfalls that occur from natural ventilation. Zehnder HRV or ERV works to exhaust air from moist rooms like bathrooms and kitchens while introducing a balanced amount of fresh air into habitable spaces like bedrooms and living rooms. With these mechanical ventilation systems, home and building owners have greater control of proper building ventilation, regardless of external factors like the weather or the time of year.
