Fresh Air Systems
Healthy Ventilation with Energy Recovery
System Overview
Fresh Air Systems, also known as Energy Recovery Ventilators (ERV) or Heat Recovery Ventilators (HRV), provide controlled ventilation while maintaining indoor comfort. These systems continuously exhaust stale indoor air and bring in fresh outdoor air, recovering up to 85% of the energy from the exhaust air to precondition the incoming fresh air. This significantly reduces the energy penalty associated with ventilation. Fresh air systems are essential for modern energy-efficient buildings that are tightly sealed, preventing issues like sick building syndrome, condensation, and indoor air pollution.
