Working on a school that will be completed by June 1, moving furnishings in July 1, and people in August. We have the month of June for flush out, hypothetically. We want to chase this credit, but the engineers say the VRF system won't push the volume of air through the system fast enough. First, we don't need to use any special filters for this, right? So it's not a matter of flushing with special filtering, correct? We aren't using Merv13 filtering in this project, we just want to flush out the off-gassing pollutants from finished construciton. Second, if the mech system can't push enough volume through, is there a low cost alternative that still accomplishes the intent of this credit.
