Application Considerations for
Changeover-Bypass-VAV
A building with varying loads due to occupancy, time-of-day, or other
special needs is a likely candidate for a changeover-bypass VAV system.
Also, any structure required to meet the higher ventilation requirements
associated with ASHRAE Standard 62 is a prime target. These
applications include:
• Offices and small manufacturing buildings – Varying occupancy
places varying demands on the HVAC system.
• Schools – Heightened concerns about indoor air quality (IAQ) affect
both new and existing applications.
• Strip malls, movie theaters, health clubs – Variable vacancy and
special needs for conditioned air apply in these buildings.
• Clinics, nursing homes, small hospitals – These buildings can be
multi-purpose and almost always have special requirements for
conditioned air.
