Your Neighbor's House Is Costing Them More Every Year (Here’s Why Energy-Efficient Homes Matter)

Electricity bills in Oklahoma have quietly become one of the fastest-growing household expenses most families aren't planning for.

According to the Wall Street Journal, U.S. electricity rates have climbed nearly 30% since 2020—outpacing inflation and most other major household costs. Utilities are expected to keep raising rates over the next decade as they upgrade aging infrastructure. That's not a temporary spike. It's a structural shift.

For most homeowners, there's nothing to do about it. Their house was built to minimum standards years ago, and the inefficiency is baked into the walls, the ductwork, the windows. Every degree the thermostat moves costs them more than it should.

And energy isn’t the only long-term cost most homeowners underestimate. Unexpected repairs and system replacements can have an even larger financial impact over time—something we break down in our guide on new vs old home cost of ownership and hidden costs.

But that's only true if you buy or build a home that was designed to the minimum. Not every home is.

What "Code Minimum" Actually Means

Most Oklahoma homebuilders build to the state's energy code—and stop there.

That's not a criticism. It's just the reality of how production building works. Meeting code is the legal requirement. Going beyond it costs more upfront, and most builders pass that decision to buyers by simply not offering it.

Oklahoma's residential energy standards follow the 2015 International Residential Code and the 2009 International Energy Conservation Code for Climate Zone 3A. Under those guidelines, a code-minimum home requires:

R-13 insulation in exterior 2×4 walls
R-30 insulation in attic spaces
Windows with a U-factor of 0.40 and solar heat gain coefficient of 0.30

Those numbers meet inspection requirements. They do not meet Oklahoma's weather.

In a climate with triple-digit summers, sudden winter cold snaps, high humidity, and severe winds, a home built to minimum standards is a home that works harder than it should to keep you comfortable—and sends you the bill every month.

The Difference Between Built to Code and Built to Perform

At Two Structures Homes, we build to Energy Star certification—verified through third-party testing, not just internal claims. Here's what that means in practice.

Walls that actually insulate. We build with 2×6 exterior walls instead of the standard 2×4, which allows for significantly deeper insulation. Every wall system includes Tyvek weather wrap, OSB sheathing, and a drainage plane that manages moisture while tightening the home's air seal. We add a super seal package and drywall gasket system to close the gaps that standard construction leaves behind.

Windows that work with Oklahoma's climate, not against it. Our argon gas-filled, low-emissivity windows carry a U-value of 0.29 and a solar heat gain coefficient of 0.22. The state minimum is 0.40 and 0.30. That difference means measurably less heat entering your home in summer, measurably more warmth retained in winter, and UV filtration that protects your floors and furniture over time.

HVAC systems designed from the start—not just installed. Efficient equipment in a poorly designed duct system is still an inefficient home. We size and balance our mechanical systems properly, run R-8 ductwork that's sealed and kept in conditioned or shaded spaces, and design for even temperatures throughout the home rather than hot and cold spots that force the system to work overtime.

Hot water that doesn't waste energy waiting. Every Two Structures home includes tankless hot water heating, eliminating the standby energy losses of traditional tank systems. You get hot water faster and use less energy producing it.

Ventilation that improves what you breathe. Proper ventilation matters in a well-sealed home. Our systems continuously circulate fresh, filtered air and maintain balanced humidity—without losing conditioned air in the process.

Most of these aren’t things you see during a walkthrough. But they show up every month on your utility bill.

What This Means for Your Monthly Bill

We routinely see homeowners in older homes spending $200 to $300 more per month on utilities than they expected—especially during peak summer and winter months. It's not because they're using more energy. It's because their home requires more energy to stay comfortable.

Efficiency is easy to talk about. Numbers make it real.

If a standard-built home in your neighborhood spends $2,000 a year on energy, a Two Structures home built to Energy Star standards can realistically save 25% or more—roughly $500 annually at current rates. Over ten years, before accounting for continued rate increases, that's $5,000 to $8,000 in avoided costs.

But here's the part worth sitting with: as electricity rates continue to rise, the value of efficiency compounds. Every kilowatt-hour your home doesn't consume saves you more money next year than it did this year. A home built for performance today becomes a more valuable financial asset every time the utility company raises its rates.

Your neighbor in a code-minimum home can't do anything about that. You can—but only if you make the decision before you build.

Built for Oklahoma Specifically

Central Oklahoma doesn't get mild weather. It gets extremes—and those extremes expose every weakness in a home's envelope.

A house that barely meets minimum code in a temperate climate is genuinely stressed by an Oklahoma August or a sudden February ice storm. The HVAC runs longer. The temperature swings inside. The bills spike.

Two Structures homes are built for this climate specifically—from Deer Creek and Edmond to Mustang and surrounding communities. Tighter envelopes, better windows, smarter duct design, and post-tension foundations that handle Oklahoma's soil conditions. Not because it's required, but because it's what actually performs here.

The Real Cost of a Home Is What You Pay Over Time

The check you write at closing isn’t the total cost of homeownership.

The mortgage payment is just one number. The utility bill is another. And unlike your mortgage, your utility bill isn't fixed—it goes up every year, at whatever rate the utility company decides.

The homes that cost less to own aren't always the ones with the lowest purchase price. They're the ones where the systems were designed to perform from day one, so that every rate hike hits a smaller number.

Energy efficiency isn't an upgrade we offer. It's the standard we build to—because we think the total cost of ownership matters as much as the number on the contract.
