This four-hour live, interactive webinar will review a wide range of ventilation topics including system design, specification and installation for high-performance, small- to medium commercial buildings. Attendees will learn about advances in dedicated outside air systems (DOAS) and the pairing of HRVs/ERVs. Participants will also learn about very high efficiency heating and cooling systems and optimized system design. This HVAC design approach has yielded significant energy and cost savings in buildings across the Northwest while providing better indoor air quality and improved occupant comfort.
