About this Event

Comparison of HRV, ERV and Smart Ventilation Systems - What's the best? - Free CEU Webinar

The course will provide a description of residential HRV (Heat Recovery Ventilator), ERV (Energy or Enthalpy Recovery Ventilator) and Smart DCV (Demand Control Ventilation) systems. Energy and humidity impact on a residence in different climatic regions and varying occupancy will be presented. The importance and value of active monitoring and control of indoor air quality will be discussed.

Lessons Learned

  1. Differentiate the characteristics of HRVs, ERV, and Smart Ventilation systems and how they help with LEED BD + C Homes V4 Smart Local Exhaust

  2. Understand the difference between "ventilation standards" (ASHRAE 62.2), Passive House requirements, LEED BD + C Homes V4 enhanced whole house ventilation credits and indoor air quality

  3. Articulate the systems that maintain healthy indoor air conditions in different climatic regions with variations in occupancy and how to ensure LEED BD + C Homes V4 pre-occupancy flush is completed. 

  4. Gain an understanding of the value of human productivity relative to the energy cost of ventilation system operation
