Course Overview

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.
