Choosing the right Heat Recovery Ventilator (HRV) or Energy Recovery Ventilator (ERV) for your home is easier now that the Home Ventilating Institute (HVI) has developed and published new performance ratings.
To assess product efficiency, the Adjusted Sensible Recovery Efficiency (ASRE) and the Adjusted Total Recovery Efficiency (ATRE) metrics were developed by HVI in cooperation with independent testing laboratories. Products are evaluated for airflow performance, as well as for effectiveness of transferring heat or energy. The higher the ASRE rating, the more efficient the product.
HVI-Certified product performance ratings for HRVs and ERVs are available online at www.hvicertified.org. Be sure to compare ratings as part of your decision-making process when selecting an HRV or ERV for your home.
