What Colorado’s 2025 Energy Code Means for Your Windows
Colorado is gearing up for a major shift in how homes are built and upgraded. By 2025, all new construction will need to meet stricter energy-efficiency standards. While that might sound like a headache, especially if you’re thinking about replacing your windows soon, it doesn’t have to be. In fact, if you’re working with Zen Windows Colorado Springs, you’re already ahead of the game.
Here’s what the 2025 energy code changes mean for your windows, why it matters, and how we make sure you’re not caught off guard.
What Is Colorado’s 2025 Energy-Efficiency Code?
In 2022, Colorado passed House Bill 22-1362, a law designed to significantly reduce energy use in buildings. It requires cities and counties across the state to adopt updated energy codes. Specifically, the 2021 or 2024 International Energy Conservation Code (IECC) had to be adopted by July 1, 2025.
These codes don’t just apply to new builds. They also affect home upgrades, including window replacements. For homeowners in Colorado Springs, this means any future window project could be subject to tighter energy standards, depending on how the local jurisdiction implements the code. El Paso County may set its own enforcement date, but most municipalities will follow the state’s timeline.
The focus of the law is simple: better insulation, reduced energy waste, and lower greenhouse gas emissions. For windows, this translates to improved thermal performance, which brings us to a term you’re going to see a lot more of soon: U-factor.
Do You Really Need Triple-Glazed Windows Now?
Here’s where things start to sound technical. The 2025 energy code raises the bar for window performance by setting lower U-factor limits.
What is U-factor, and why does it matter?
Put simply, the U-factor measures how well a window keeps heat from escaping. The lower the number, the better the insulation. For Colorado’s climate zone (Climate Zone 5), the new target under the 2021 IECC is a maximum U-factor of 0.30 for replacement windows.
Does that mean you’re stuck choosing bulky, triple-glazed windows? Not necessarily. Triple-glazed windows can help in extreme climates or passive home builds, but they’re not always required to meet the code. Zen Windows Colorado Springs offers double-glazed options with Low-E coatings and argon gas fills that already meet or exceed the 0.30 threshold. In other words, our standard windows are already compliant, even before the law takes effect.

Insights for Colorado Springs
While this energy code is a statewide initiative, what it looks like in practice can vary by location. In El Paso County, local officials may adopt the changes with a slightly different timeline or interpretation. We’re keeping close tabs on the rollout and will update customers as needed.
That said, Colorado Springs’ high elevation and seasonal extremes make efficient windows especially valuable. Intense sun exposure, dry air, and wide temperature swings mean heat loss (and gain) happens fast.
Windows that perform well year-round aren’t just a code requirement; they’re a smart upgrade.
We also encourage homeowners to check with local utilities or rebate programs. While incentives can change, there have historically been offers from energy providers that help offset the cost of high-performance windows. If anything is currently available, we’ll make sure you know about it.
Ready to Replace? Let’s Keep It Simple.
If you’re thinking about replacing your windows before 2025, or you just want to get ahead of the curve, now’s a great time. Prices aren’t spiking yet, supply is steady, and our process takes all the guesswork out of the equation.
