Energy efficient windows: A how-to and buyer's guide

When shopping for new or replacement windows and doors, energy efficiency plays a crucial role. Various energy-efficient aspects and advantages come into play, such as cost, energy savings, enhanced comfort, and a positive impact on environmental sustainability. These are key factors to consider during your research

Why energy efficient windows?

Upgrading or replacing your windows can bring numerous advantages, especially when it comes to enhancing the energy efficiency of your home.

Save money.

ENERGY STAR® certified energy-efficient windows offer a practical way to lower monthly energy expenses and enhance your home’s comfort throughout the year. Poorly insulated or drafty windows can cause your home to consume more energy annually, resulting in higher energy bills and putting extra strain on your HVAC systems.

Increase comfort.

Energy-efficient windows, equipped with the right glass options, can help maintain a comfortable home environment throughout the year by reflecting heat during summer and retaining warmth in the winter.

Environmentally responsible.

Energy-efficient windows contribute to a more sustainable environment by lowering your home’s carbon footprint and extending the longevity of its energy systems. Andersen provides products crafted from its proprietary Fibrex® composite, which contains 40% reclaimed wood fiber by weight. Additionally, Fibrex material offers double the strength of vinyl.

What are energy-efficient windows?

Frame Materials
The choice of frame material is crucial for enhancing energy efficiency. Common materials include wood, vinyl, composite (such as Fibrex® material), and fiberglass. The potential savings and costs can differ significantly depending on the material used and its manufacturing process.

Glass
Opting for double-pane (or dual-pane) glass is more effective for energy efficiency compared to single-pane glass. The airspace between the panes provides an extra layer of insulation against temperature changes. Additionally, Low-E glass is particularly beneficial for energy conservation, as it minimizes the penetration of ultraviolet (UV) and infrared light, thereby reducing heat transfer.

How do I know if a window is energy efficient?

Look for Certification Labels:
- Check for the ENERGY STAR® logo or National Fenestration Rating Council (NFRC) logo on windows or doors.
- Most window installers and companies promote NFRC-labeled and ENERGY STAR-certified products, indicating energy efficiency.
How to Read the Label:
- Ensure the window or patio door has an NFRC label.
- This label allows for measuring and comparing energy performance among similar products.
- If a product lacks this label, it means the NFRC has not verified its claims.

How do energy efficient windows work?

To obtain ENERGY STAR certification on a window or door, a manufacturer must pass an independent performance test created by the non-profit National Fenestration Rating Council (NFRC). The test measures and rates a window’s energy efficiency based on five factors:

Do energy-efficient windows increase home values?

Yes! In addition to helping save on your energy bills, replacing and upgrading windows can have a direct impact on the value of your home. Window replacement may not be the most noticeable home improvement project, but its impact on your home’s equity is certain.

According to 2018 data from Remodeling Magazine, the national return-on-investment (ROI) average for wood window replacement is 69.5%, higher on average than popular midrange projects such as a major kitchen remodel (59%), bathroom addition (59.9%) or a backyard patio (47.6%).

How much money do energy efficient windows save?

According to energystar.gov, ENERGY STAR certified windows can save an average of 12% on energy bills each year1. If windows are single-pane, an estimated savings for ENERGY STAR certified windows is between $101-583 per year. If windows are double-pane, savings estimates range between $27–$197 per year2.

Actual savings will vary based on local climate conditions, window type (single-/double-pane, frame material), utility rates and individual home characteristics.
