Meet 2021 Washington Energy Code Requirements with Broan
Broan Heat / Energy Recovery Ventilators (HRVs / ERVs) represent the most efficient way to ventilate and prevent energy loss when compared to other solutions.
Broan’s line of HRVs and ERVs:
- Meet ASHRAE 62.2 - 2010 Required Continuous Ventilation Rate (CFM).
-
Provide continuous, balanced ventilation that will result in earning higher energy credits.
-
Are simple to install with:
- Automatic balancing and easy-to-set airflow speeds.
- Flexible mounting configurations.
- Compatibility with various types of exterior wall terminations.

*At the discretion of the local code official, the HRV / ERV Adjusted Sensible Recovery Efficiency (ASRE) rating can be deemed an alternative method to the SRE rating.
What Washington code changes mean for builders
Whether single or multi-family, energy credits are based on the efficiency of the Heat / Energy Recovery product and the air leakage of the dwelling. All Group R-2 dwellings require the HRV / ERV to have 60% minimum SRE (effective March 15, 2024).
Bottom line: Balanced ventilation with Broan HRVs and ERVs can result in significant earnings of energy credit points.
