Beside this, can ERV be used for makeup air?
You can bring makeup air into a tight house in three ways: through the HVAC system using dampers; through wall- or ceiling-mounted grilles; or through mechanized makeup-air solutions. Some tight homes also can benefit from the use of a heat-recovery ventilator (HRV) or an energy-recovery ventilator (ERV).
