Ventilation is an important part of making a building safe and comfortable, but it can require a significant amount of energy to properly condition that air. In this webinar, we will discuss dynamic ventilation control strategies to vary the amount of outdoor air brought into the building as operating conditions change.

Watch the webinar on-demand:



Learning objectives:

  • Define the requirements and 2013 revisions of ASHRAE Standards 62.1 and 90.1 as they relate to dynamic ventilation reset control strategies.
  • Apply various demand controlled ventilation strategies to single-zone systems, dedicated outdoor-air systems, and multiple-zone VAV systems.
  • Identify applications for various technologies used for demand-controlled ventilation.
  • Describe the requirements for implementing dynamic ventilation reset control strategies into existing systems.

WHO SHOULD WATCH? Architects, building owners, engineers, contractors, HVAC system designers, energy efficiency specialists, facility managers, control system technicians, HVAC equipment manufacturer's representatives, facility engineers and anyone interested in learning more about ventilation strategies.
