Energy Performance Data

ENERGY STAR

®

– United States

ENERGY STAR is a government-

regulated program that was created by

the Environmental Protection Agency

(EPA), and the U.S. Department of Energy

(DOE), to help consumers quickly and

easily identify energy saving products.

The ENERGY STAR program uses energy

values obtained by window and door manufacturers through

the National Fenestration Rating Council (NFRC) program.

NFRC ratings are based on the energy performance of the

total window or door – both glass and frame.

The ENERGY STAR program for the United States divides

the nation into four separate climate zones – Northern,

North-Central, South-Central, and Southern.

The performance criteria that needs to be met in order to

be ENERGY STAR

compliant in a specific climate zone

(effective January 1, 2015) is shown in the charts provided.

Kolbe demonstrates a commitment to providing accurate energy data by having products independently simulated, tested, inspected and listed in the NFRC certification

program, and making that data available on our website and window labels.

NOTE: Energy performance data and air, water, structural data is updated on a continuous basis. For the most current information, visit
