2023 ENERGY STAR® Partner of the Year Winner


The U.S. Environmental Protection Agency has awarded Delta Breez with the 2023 ENERGY STAR® Partner of the Year - Sustained Excellence award!

It is our honor to be an ENERGY STAR Partner of the Year for the eight year in a row, and to receive further recognition with the Sustained Excellence designation. Delta is a leading provider of DC brushless fans – a key technology for improving the efficiency of a wide range of solutions – such as our Delta Breez ventilation fans. Delta Breez prides ourselves on delivering ENERGY STAR-qualified products, some of which exceed the ENERGY STAR efficiency requirement by over over 315%.

The ENERGY STAR Partner of the Year for Sustained Excellence not only values Delta’s leadership in energy efficiency over the years, but also its excellent commitment to training employees and educating customers on the benefits of the ENERGY STAR program and the certification of over 90 percent of our Delta Breez fans.


ENERGY STAR, a joint program of the U.S. Department of Energy and the U.S. Environmental Protection Agency, identifies products in over 60 categories which meet rigorous energy efficiency standards. Established in 1992, ENERGY STAR is an internationally recognized label for U.S.-originating products that reduce greenhouse gas emissions without sacrificing performance or quality. ENERGY STAR-qualified products protect the environment by reducing energy consumption, which also reduces greenhouse gas emissions and saves consumers money on utility bills.

As an ENERGY STAR partner, Delta strives to engineer solutions that meet and surpass current standards in energy efficiency. Delta Breez prides ourselves on delivering ENERGY STAR-qualified products, some of which exceed the ENERGY STAR efficiency requirement by over over 315%. With 106 ventilation fan models evaluated in 2023, 97 (92%) models have been recognized as ENERGY STAR-qualified.

ENERGY STAR Most Efficient

ENERGY STAR Most Efficient is a designation that recognizes the top products for the ENERGY STAR label. ENERGY STAR Most Efficient products reduce greenhouse gas emissions by meeting the most stringent energy efficiency performance levels set by the U.S. Environmental Protection Agency.

Delta Breez currently has 97 ENERGY STAR®-qualified bathroom fans, with some models even exceeding the criteria by 315 percent. In fact, the Delta fans from the BreezCeilingFan, BreezSignature, and BreezElite lines meet the toughest efficiency criteria set by the EPA – ENERGY STAR® Most Efficient 2024.


ASHRAE 62.2 publishes a national standard that applies to single-family homes and multi-family dwellings to ensure proper ventilation and acceptable indoor air quality. The standard is referenced in building codes and widely accepted by architects, engineers and mechanical contractors. ASHRAE 62.2 addresses minimum ventilation effectiveness and noise level performance of continuous and intermittent mechanical exhaust systems.

The following table summarizes the ventilation air requirements in CFM for various floor areas:

Ventilation Air Requirement, CFM

Floor Area Bedrooms
(ft2) 0-1 2-3 4-5 6-7 > 7
< 1500 30 45 60 75 90
1501-3000 45 60 75 90 105
3001-4500 60 75 90 105 120
4501-6000 75 90 105 120 135
5001-7500 90 105 120 135 150
> 7500 105 120 135 150 165

Most Delta Breez fan models are ASHRAE 62.2 compliant for both intermittent and continuous run applications. This means Delta Breez fans are operable according to 62.2 guidelines for airflow and meet the minimum noise level requirements.

HVI logo

HVI, the Home Ventilating Institute, is an organization that runs a standardized testing and certification program for a range of home ventilating products. Products are tested to qualify for various performance parameters and undergo random verification. All tests are conducted in third-party facilities that are independent of any manufacturer, while testing procedures are designed by HVI members according to internationally recognized guidelines. All Delta Breez ventilation fans are HVI lab tested and certified.
