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). ​
                 - CFM = ((.01 x sq. ft.)) + (7.5 x (number of bedrooms + 1)) 
 
  • 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 

washington2.pngWhether 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.
