Why It Matters01
Sealed tight, ventilated by design.
Because airtight buildings require controlled ventilation, fresh air is supplied mechanically through an Energy Recovery Ventilator equipped with MERV 13 filtration.
Incoming air is pre-warmed (or pre-cooled) by the outgoing exhaust through a heat-exchanging core — so ventilation doesn’t dump the heating dollar out the wall. During wildfire smoke events, the filter keeps the home livable.
