Residential
Replacing your home's windows is one of the biggest single line items in any renovation budget — and one of the few that genuinely pays you back. In Alberta, a properly chosen Energy Star window can qualify for provincial and federal rebates, cut your heating bill by up to 20%, and add measurable resale value to the home.
Here's what you need to know in 2026 to make sure you don't leave rebate money on the table.
What "Energy Star certified" actually means
Energy Star Canada certifies windows based on three metrics: U-factor (heat retention), SHGC (solar heat gain), and ER (overall energy rating). Alberta falls under Energy Star's Zone 2 (Edmonton, Calgary) or Zone 3 (further north).
The programs available in 2026
- Federal: Canada Greener Homes — grants for window upgrades meeting Energy Star thresholds, requires pre/post EnerGuide evaluations.
- Provincial: Alberta energy efficiency programs — utility-funded and municipal rebates, particularly through EPCOR partnerships.
- Utility / municipal top-ups — first-come-first-served stacking rebates.
Which upgrades qualify
For most Alberta homes, the sweet spot for ROI is a double-pane Low-E argon-filled window. Triple pane gives better performance but the marginal saving doesn't always pay back the price difference unless you're in a very cold or noisy area.
How to claim
- Get an EnerGuide pre-evaluation before installation.
- Keep every invoice and Energy Star NRCan sticker.
- Use a certified installer (Progress Glass installers are licensed Alberta journeymen).
- Get the post-retrofit evaluation within the program deadline.
- Submit your rebate application — processing typically takes 6–12 weeks.
