How ENERGY STAR Certified Windows Boost Your Home's Value
Tired of high energy bills and a home that's too hot or too cold? The solution might be simpler than you think. Since 1992, ENERGY STAR has been quietly transforming homes, starting with energy-efficient computers and expanding to revolutionize the entire residential sector. Whether building or upgrading your home, this guide reveals how ENERGY STAR certified windows in OKC, empowers you to create a more comfortable, efficient, and sustainable space.
The Evolution And Impact Of ENERGY STAR
1992: Humble Beginnings: The Environmental Protection Agency (EPA) launched ENERGY STAR to combat greenhouse gas emissions, initially focusing on energy-efficient computers and monitors.
Expansion Beyond Electronics: The program rapidly expanded to include a wide range of products, including ENERGY STAR certified windows, appliances, lighting, and heating/cooling systems, totaling 70,000 products across various categories by 2019.
"Most Efficient" Designation: Only a select few products, roughly 4%, achieved the prestigious "Most Efficient" label, signifying exceptional energy performance.
Empowering Homeowners and Builders: ENERGY STAR extended its reach to the residential sector, providing resources and programs for new constructions and existing homes.
New Construction Excellence: ENERGY STAR-certified new homes, whether single-family, multi-family, or manufactured, consistently surpassed building code energy efficiency standards by an average of 20%.
A Holistic Approach to Efficiency: Beyond individual products like ENERGY STAR certified windows, ENERGY STAR fostered a comprehensive approach to energy efficiency, addressing various aspects of residential and commercial buildings.
Continued Innovation: ENERGY STAR continues to evolve, driving innovation in energy-efficient technologies and setting higher standards for a sustainable future.

Key Qualifications Of ENERGY STAR Certified Windows And Doors
To earn the prestigious ENERGY STAR label, windows and doors must meet the following criteria:
Certified Manufacturer: Produced by an ENERGY STAR partner, ProVia, ensuring commitment to energy-efficient manufacturing practices.
Rigorous Testing: Undergo and pass comprehensive testing, certification, and verification by the National Fenestration Rating Council (NFRC) for accurate performance data.
EPA Compliance: Achieve NFRC ratings that meet or exceed the strict energy efficiency guidelines set by the Environmental Protection Agency (EPA), guaranteeing energy savings for consumers.
Deciphering NFRC Ratings For Energy-Efficient Windows And Doors:
Understanding The Metrics
U-Factor: This measures a window or door's insulation effectiveness. Lower U-factors signify superior insulation, minimizing heat transfer and maintaining consistent indoor temperatures regardless of outdoor conditions.
Solar Heat Gain Coefficient: SHGC quantifies the amount of solar heat that passes through the glazing. In warmer climates, lower SHGC values are preferred to reduce heat gain. Colder climates might benefit from slightly higher SHGC to harness passive solar heating.
Visible Transmittance: VT indicates the percentage of visible light transmitted through the window or door. Higher VT values allow for more natural light, potentially decreasing reliance on artificial lighting.
Air Leakage: This measures the rate of air infiltration around the window or door. Lower AL values indicate a tighter seal, preventing drafts and energy loss.
Optimal Ratings For The North-Central Climate Zone
U-Factor ≤ 0.30: To ensure adequate insulation during both hot summers and cold winters.
SHGC ≤ 0.40: To balance solar heat gain for year-round comfort.
Door Ratings Based On Glazing Level
Opaque Doors: U-factor ≤ 0.17 (no glass)
Less Than 50% Glass: U-factor ≤ 0.25 and SHGC ≤ 0.25
More Than 50% Glass: Follow the same U-factor and SHGC guidelines as windows for the specific climate zone.
