About ENERGY STAR®
ENERGY STAR® is a voluntary program created by the EPA that helps businesses and individuals reduce energy consumption to save money and protect the environment.
Why choose ENERGY STAR® qualified windows and doors from D-Wing Construction?
Replacing old windows with ENERGY STAR® qualified windows can lower household energy bills by 7 to 15 percent,
according to the U.S. Environmental Protection Agency (EPA).
Lower energy consumption also reduces greenhouse gas emissions from power plants and shrinks a house's carbon footprint.
With thousands of ENERGY STAR® qualified windows and doors, D-Wing Construction can help improve the comfort and energy
efficiency of your home while also providing style and long-lasting durability. Simply tell your D-Wing Construction
in-home sales consultant that you want ENERGY STAR qualified windows and doors.
How do D-Wing Construction windows and doors earn the ENERGY STAR® label?
To earn the ENERGY STAR® label, windows and doors must meet rigorous energy performance levels.
Qualified products must also have third-party certification based on testing in recognized laboratories.
ENERGY STAR® divides the U.S. into four climate zones, each with its own unique set of energy performance
requirements (shown above). Energy efficiency for windows and doors is compared by using two important measurements:
U-Factor and Solar Heat Gain Coefficient (SHGC).
In the northern zones, U-Factor and SHGC requirements focus on helping reduce the need for heating.
In the southern zones, requirements generally aim to reduce the need for air conditioning.
Special glass coatings help control how much of the sun's heat enters and how much of the controlled air temperature inside escapes.
Because D-Wing Construction offers a variety of glazing packages, including several high performance glass options,
a professional D-Wing Construction in-home sales consultant can configure windows best suited for our climate zone.
