This session explores three practical approaches–-good, better, and best—for meeting balanced ventilation requirements without relying on a central HVAC system as required in the recently adopted 2026 ORSC. Presenters compare (1) a cost-effective inline supply fan paired with a dedicated exhaust fan, (2) spot ERVs serving key living areas, and (3) a ducted HRV/ERV with minimal ductwork. Attendees will learn when each option makes sense, how to size and commission them, and the trade-offs related to cost, complexity, performance, and code compliance. Real-world examples highlight systems that pass inspection and perform reliably in the field.
