What’s the Difference Between ENERGY STAR® and the NFRC?

When shopping for new windows or doors, understanding the difference between ENERGY STAR® and NFRC labels is crucial. Both provide valuable information about the energy efficiency of their products, but they serve slightly different purposes. Renewal by Andersen® of Central Pennsylvania explains more in this article.

Understanding ENERGY STAR Certification

ENERGY STAR is a widely recognized program that labels products that meet strict energy efficiency guidelines set by the U.S. Environmental Protection Agency (EPA). ENERGY STAR-certified windows, doors, and skylights are independently tested and verified to be high-performing and energy-efficient. These products help to lower energy bills by up to 13 percent nationwide, reducing greenhouse gas emissions and promoting environmental sustainability.

For homeowners in Central Pennsylvania, ENERGY STAR-certified products cater to specific climates. The ENERGY STAR label indicates that the product has been certified to perform well in Northern, North-Central, Southern, or South-Central climate zones, which is essential to achieving the energy savings specified.

What You Need to Know About the NFRC Label

The National Fenestration Rating Council (NFRC) is another key player in the window and door industry. Unlike ENERGY STAR, which is primarily an endorsement label, the NFRC provides a comprehensive rating system that quantifies a product’s energy performance. The NFRC label can be found on all ENERGY STAR-certified products and includes detailed information on how a window, door, or skylight performs in terms of:

• U-Factor: The rate of heat loss
• Solar Heat Gain Coefficient (SHGC): How much solar radiation is admitted
• Visible Transmittance: The amount of visible light transmitted
• Air Leakage: The rate at which air passes through joints
• Condensation Resistance: How well the product resists water buildup

The Complementing Roles of ENERGY STAR and NFRC

Homeowners use both ENERGY STAR and NFRC labels together to make informed decisions. While ENERGY STAR signifies overall energy efficiency and climate zone suitability, the NFRC offers detailed metrics for comparing specific performance aspects between different products.

Installing ENERGY STAR-certified windows and doors is more than just about selecting the right product. Proper installation according to manufacturer instructions is critical to ensuring the energy efficiency benefits are fully realized. Trained professionals should evaluate and carry out the installation process to protect the investment and the intended energy savings.

Maximizing Local Benefits

For residents in Central Pennsylvania, prioritizing energy efficiency can lead to noticeable savings not just in energy costs but also in long-term home comfort. Local rebates and federal tax credits may be available as incentives for choosing ENERGY STAR-certified products. As such, be sure to check current local promotions and utility-sponsored rebates when considering an upgrade.
