Energy-Efficient, Energy Star® Certified Homes in Oklahoma City

Energy-Efficient Homes in Oklahoma: Built for Performance, Not Just Code

Engineered for Comfort. Built for Durability. Verified for Performance.

Oklahoma’s climate is hard on homes. Extreme heat, humidity swings, wind, and expansive clay soil demand more than minimum standards. At Two Structures Homes, energy efficiency is engineered into the structure, the systems, and the details—then verified by independent testing.

This is not a checklist. It is a performance strategy.

Every home we build is independently tested and certified through OG&E’s Positive Energy Program and verified using national performance standards, including the Home Energy Rating System (HERS) and Energy Star® Certification. This ensures our energy-efficiency claims are measured, documented, and proven—not just marketed.

What Energy Efficient Really Means (And What It Doesn’t)

“Energy-efficient” is one of the most commonly used—and misunderstood—terms in homebuilding.

Many builders advertise homes as “energy-efficient” because they include upgraded appliances, LED lighting, or higher-efficiency HVAC equipment. While these components can reduce energy use, individual upgrades alone do not make a home truly energy efficient.

True energy efficiency requires a whole-home approach, where all systems are designed to work together. This includes the building envelope, air sealing, insulation, duct design, ventilation, equipment sizing, and third-party performance verification.

Without this integrated approach, high-efficiency equipment is often compensating for construction deficiencies. A home may include energy-efficient appliances and lighting yet still experience uneven temperatures, higher utility bills, or comfort issues if air leakage, insulation continuity, or system balance are not properly addressed.

At Two Structures Homes, energy efficiency is not defined by a checklist of upgrades. It is achieved through intentional design, coordinated construction, and verified performance, ensuring that each component contributes meaningfully to how the home actually operates.

A genuinely energy-efficient home is designed around:

  • A tight and well-sealed building envelope
  • Properly sized and balanced HVAC systems
  • Controlled airflow and ventilation
  • Verified performance through third-party testing

Quick tip for comparing builders: Ask whether the home is tested (blower door + duct testing) and whether results are documented (HERS + Energy Star).

What "Energy Efficient" Actually Means in Oklahoma

When most builders talk about energy efficiency, they point to appliances, windows, or HVAC equipment. Those components matter—but they do not determine how a home performs over time.

In Oklahoma, true energy efficiency starts with:

  • A tight, continuous building envelope
  • Proper moisture and air control
  • Insulation installed for performance, not speed
  • Mechanical systems designed for the house—not the other way around
  • Independent third-party verification

Without those fundamentals, high-efficiency equipment is simply compensating for a poorly performing structure.

We build the structure first. The equipment supports it.

Designed for Oklahoma’s Climate and Soil—Not Generic Specs

Oklahoma is not an easy place to build high-performance homes. Our climate combines:

  • Extreme summer heat
  • High humidity
  • Rapid seasonal temperature swings
  • Heavy rainfall events
  • Expansive clay soils that move with moisture

Homes that perform well here are not accidental. They are intentionally designed and built for these conditions. That intent shows up in the details most buyers never see.

That is why our construction approach focuses on:

  • Advanced framing and air-sealing strategies
  • Proper vapor management
  • Post-tension foundations to control movement
  • Ventilation strategies that actually work in humid climates
  • Assemblies designed to manage heat, moisture, and pressure long-term

Energy efficiency in Oklahoma is about control, not just insulation.

Why Choose an Energy-Efficient Home?

Energy efficiency is not just about saving money. It is about how the home lives.

Key advantages include:

  • Lower utility bills—often up to 20% annually
  • More consistent indoor temperatures year-round
  • Improved indoor air quality and comfort
  • Reduced strain on HVAC systems and longer equipment life
  • Less moisture intrusion and fewer maintenance issues
  • Increased resale appeal and long-term value

An energy-efficient home is quieter, more comfortable, and better suited for Oklahoma’s wide temperature swings and humidity levels.

Advanced Water Management

Thoughtful exterior water management, flashing details, and drainage strategies protect the home’s structure and indoor environment.

Energy Star®, HERS Scores, and Third-Party Verification Explained

What Is Energy Star® Certification?

Energy Star® certification verifies that a home meets strict performance standards set by the U.S. Environmental Protection Agency. Certification requires verified construction practices, proper system design, and independent inspections.

HERS Scores: What They Measure and Why They Matter

Every Two Structures home is independently tested and HERS rated. This is third-party verification—not marketing language.

A lower HERS score indicates lower energy use compared to a standard code home. More importantly, it confirms:

  • Proper air sealing
  • Correct insulation installation
  • Duct performance
  • Overall system efficiency

Why HERS Scores in the 30s Are Rare Without Solar

In most cases, HERS scores below 40 require renewable energy systems, such as solar, or very specialized construction strategies.

Our typical HERS range of 40–50 reflects a balance between measurable energy savings, construction practicality, long-term reliability, and cost effectiveness for homeowners.

Why Energy-Efficient Homes Can Cost More Upfront

Building a high-performance home often requires a greater upfront investment due to better assemblies, tighter construction tolerances, and third-party testing.

In return, homeowners typically gain:

  • Lower operating costs
  • Fewer comfort and moisture issues
  • Reduced warranty and maintenance concerns
  • Greater long-term value and durability

Energy efficiency should be evaluated as a cost-of-ownership decision, not just a line-item upgrade.

Who Benefits Most From an Energy-Efficient Home?

  • Families with allergies or respiratory sensitivities
  • Work-from-home households
  • Long-term homeowners
  • Buyers focused on comfort and predictability
  • Homeowners concerned about rising energy costs
