Trane Engineer’s Newsletter Live- Demand Controlled Ventilation (Greensboro)

Demand-controlled ventilation (DCV) is an energy-saving control strategy that reduces the rate at which outdoor air is delivered to a zone during periods of partial occupancy. This ENL will discuss various technologies used to implement DCV, how to apply DCV control strategies to the different types of ventilation systems, and review the related requirements for compliance with ASHRAE Standards 62.1 and 90.1.

Presenters:  Eric Sturm and John Murphy

After attending, you will be able to:

• Recognize applications for which ASHRAE Standard 90.1 and energy codes might require demand-controlled ventilation
• Identify various technologies available for implementing demand-controlled ventilation
• Apply various demand-controlled ventilation strategies to single-zone systems, dedicated outdoor-air systems, and multiple-zone VAV systems
• Understand what ASHRAE Standard 62.1 requires when implementing demand-controlled ventilation
• Identify several challenges of integrating DCV with other control sequences
