VENTILATION OVERVIEW: EXHAUST, SUPPLY, AND BALANCED

A tight enclosure that minimizes moisture and air leakage lays the groundwork for a good ventilation system also provides better energy performance for your home creating a healthy, durable, energy-conscious space. However, a tighter envelope also means that providing fresh air exchange becomes even more important. Codes and standards, building materials, climate zone, aesthetics, and occupant behavior all place demands on ventilation. Competing with these demands are your goals of achieving indoor air quality, energy performance, and durability. Learn More

Mechanical ventilation draws out pollutants and draws in make-up air in a controlled manner. Controlled ventilation strategies divide into 3 main categories: Exhaust, Balanced and Supply.

Exhaust ventilation removes pollutants at the source. Read More
Exhaust-only ventilation works by forcing air out of the home to depressurize the interior and gain make-up air through passive vents. Because this ventilation system only actively exhausts air, it is not recommended in hot or humid climates. Since any make-up air is gained passively, that air may be very humid, contain pollutants, or be too cold, leading to energy penalties for the home.
Balanced ventilation both exhausts polluted indoor air and draws in fresh, outdoor air in a balanced, controlled ratio. Read More
Balanced ventilation is appropriate for all climate zones. By coupling a balanced approach with an energy recovery or heat recovery ventilator (ERV or HRV), incoming air can be conditioned and dehumidified, saving on heating and cooling expenses for the home.
Supply ventilation dilutes pollutants by using ventilation to pressurize a home. Read More
Actively bringing fresh outdoor air inside while pushing stale inside air out. Supply systems offer better control over pollutants in incoming air, as they only obtain outdoor air through specified vents. With supply ventilation, spot ventilation bath fans are still needed to exhaust bad air, moisture and odors.

Mechanical ventilation can take the benefits of a healthy home one step further by providing a controlled source of treated fresh air that balances indoor air quality with energy savings.
