About this event

Do you know how to get the largest energy savings in your commercial buildings? HVAC as a single system is 45-70% of a building’s energy use—making it the biggest energy user and a major retrofit target. Even though this percentage depends on climate, building type, and building usage, HVAC still has one of the largest impacts on energy use. Ryan Hoger discusses a variety of energy-saving HVAC technologies and optimization considerations.


  1. Explain the mechanics and benefits of using energy recovery ventilation (ERV).
  2. Describe how economizers work and how they help satisfy ventilation code requirements.
  3. Identify the types of spaces in which CO2-based demand controlled ventilation (DCV) is most appropriate.
  4. Discuss the advantages of using variable air volume (VAV) systems.

In order to receive credit for viewing this webinar, you'll need to pass a short quiz. A link to the quiz will be provided in your registration confirmation email. Separate registration is required for each individual requiring continuing education credit.

All credits have different expiration dates, so it is to your advantage to take the quiz as soon as possible.

AFE This program supports a topic within the body of knowledge outlined by the Association for Facilities Engineering CPE/CPMM/CPS Certification Programs, and should count as 0.2 CEUs (2.0 hours) toward re-certification.

BOC This course offers up to 2 points for BOC certified operators.

BOMI This webinar is approved for 2 continuing professional development points toward renewal of the professional designations offered by BOMI International.

WI-DSPS Wisconsin Department of Safety and Professional Services has approved this course for 2 CEUs for the following credentials: Commercial Building Inspector Certification, UDC-HVAC Inspector Certification. Note that you may not retake the same course for credit more than once during the 1-, 2- or 4-year term of your specific credential.

WI-PE This course is geared towards professional engineers in the State of Wisconsin and offers up to 2 professional development hours (PDHs). The course participant must decide if this is a qualifying course as defined in the relevant Wisconsin Administrative Code https://docs.legis.wisconsin.gov/code/admin_code/a_e/13.pdf

This course will not be pre-approved for GBCI credits; however, if you believe the content is applicable to your credential, you can self-report credits.
