High performance homes require high performance ventilation
The building science approach to green home certifications such as Passive House require full-time mechanical ventilation to ensure the home has fresh air flow.
Typically an Energy Recovery Ventilator or Heat Recovery Ventilator are the best options, depending on the climate zone.
At the 2015 AHR Expo, Doug Steege, vice president of RenewAire, reviews the importance of an ERV and how it operates.
The ERV is the right choice for warmer climates where it’s necessary to remove humidity from the incoming fresh air. The ERV transfers moisture from the incoming humid air to the stale air being vented outside. ERVs are typically ducted as well, and sized based on the square footage of the home.
For colder climates, the HRV keeps the home supplied with a steady flow of fresh outdoor air. As stale, warm air is expelled, the heat recovery core warms the incoming fresh, colder air before it is distributed throughout the home. This function provides a constant supply of fresh air and helps control humidity.
Basically, HRVs exchange only heat between the airstreams, while ERVs exchange both heat and moisture.
