If you’ve been shopping for new windows lately, chances are you’ve come across the ‘ENERGY STAR®’ label. While it’s reassuring to see that blue and white sticker, many homeowners in Edmonton still find themselves wondering ‘what does it actually mean?’ And more importantly, how does it impact your energy bills, comfort and long term investment in your home?
At Knight Doors & Windows, we believe in making the technical stuff simple. So let’s break it down. Here’s everything you need to know about ENERGY STAR window ratings and how they help you choose the right windows for your Edmonton home.
What Is the ENERGY STAR® Label?
ENERGY STAR is a government approved program that certifies products, like windows and doors, that meet specific energy efficiency criteria. When you see this label, it means the product has been tested and meets and/or exceeds Canada’s energy performance standards.
For window and door installation in Edmonton, where winters can be long and intense, ENERGY STAR rated products can make a noticeable difference in reducing heat loss, improving comfort and cutting down utility costs.
Key Terms You’ll See on ENERGY STAR Labels
Here are some of the technical ratings in everyday terms:
U-Factor (or U-Value)
This means that the U-Factor measures how well a window prevents heat from escaping. It’s important to look for lower numbers. In Edmonton’s chilly climate, aim for windows with a U-Factor of 1.22 W/m²·K or lower.
Solar Heat Gain Coefficient (SHGC)
This measures how much solar heat a window lets into your home. For example, lower SHGC = less heat gain in summer. But in colder climates like Edmonton, a moderate SHGC can help with passive heating during sunny winter days.
Energy Rating (ER)
This is a Canadian rating system that combines U-Factor, SHGC and air leakage into one number. The higher the ER number, the better the window performs overall. For Edmonton, ENERGY STAR windows typically have an ER of 34 or higher.
Why ENERGY STAR Windows Matter in Edmonton
Choosing high efficiency windows isn’t just about meeting codes, it’s also about long term comfort and savings. With Edmonton’s extreme seasonal shifts, poorly rated windows can cause drafts, condensation and higher heating costs.
ENERGY STAR windows help by:
- Keeping warm air in during the winter
- Reducing summer heat gain
- Lowering energy bills
- Increasing your home’s resale value
When installed professionally by trusted experts (like us!), you’ll also enjoy better sealing, insulation and performance year round.
