Energy-Efficient Home Builder in Oklahoma City

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 Efficiency Really Means in Oklahoma

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

Many builders describe homes as energy efficient because they include upgraded appliances, low-E windows, LED lighting, or higher-efficiency HVAC equipment. Those components matter, but individual upgrades alone do not make a home truly energy efficient.

True energy efficiency requires a whole-home approach, where the structure and mechanical systems are designed to work together. In Oklahoma, where homes face extreme heat, humidity, wind, temperature swings, and expansive soils, that means paying particular attention to how the home controls air, heat, and moisture.

A genuinely energy-efficient home starts with:

  • A tight, continuous building envelope
  • Proper air sealing and moisture management
  • Insulation installed for performance and continuity
  • Properly sized and balanced HVAC systems
  • Sealed ductwork and controlled ventilation
  • Independent third-party testing and verification

Without those fundamentals, high-efficiency equipment can end up compensating for deficiencies elsewhere in the home. A house can have efficient appliances and HVAC equipment and still experience drafts, uneven temperatures, excessive energy use, or comfort problems if the envelope and mechanical systems do not perform together.

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.

We build the structure first. The equipment supports it.

Quick tip for comparing builders: Ask whether the home receives blower-door and duct-leakage testing and whether its performance is independently documented through a HERS® rating and ENERGY STAR® certification.

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 energy consumption and utility costs.
  • 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.

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: Independent Proof of Home Performance

Every Two Structures home is independently tested and HERS® rated. Our homes typically achieve HERS scores in the 40–47 range, providing measurable, third-party verification of energy performance—not just a builder’s claim.

The Home Energy Rating System (HERS) evaluates the energy performance of a home. The lower the HERS score, the more energy efficient the home is relative to the HERS reference home.

A HERS rating considers multiple aspects of home performance, including:

  • Air leakage and the performance of the building envelope
  • Insulation levels and installation
  • Duct leakage
  • Heating and cooling equipment
  • Windows and doors
  • Water-heating systems
  • Overall projected energy use

Achieving a HERS score in the 40s without relying on onsite renewable energy requires the home’s envelope, insulation, HVAC, ductwork, windows, air sealing, and ventilation to work together as a system.

For Two Structures Homes, the goal is not simply to chase the lowest possible number. It is to build a home that delivers measurable energy efficiency, comfort, durability, and long-term value for the homeowner.

Typical Two Structures Homes HERS Score: 40–47

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 risk of comfort and moisture-related problems
  • 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?

An energy-efficient home can benefit any homeowner, but high-performance construction is especially valuable for buyers who plan to stay in their home long term and care about comfort, predictable operating costs, durability, and verified performance.

It can be particularly valuable for:

  • Long-term homeowners who want lower operating costs and durable construction
  • Families who value consistent comfort with fewer drafts, hot spots, and cold spots
  • Homeowners concerned about rising energy costs who want to reduce unnecessary energy use
  • Buyers focused on indoor air quality who value controlled ventilation and better management of outside air
  • Work-from-home households that spend more hours each day heating, cooling, and occupying their home
  • Buyers who want measurable performance rather than relying solely on a builder's claims

Why Two Structures Homes Builds This Way

At Two Structures Homes, we believe energy efficiency should be measured, not assumed.

That means thinking about home performance from the beginning—not adding a few energy-efficient products at the end and calling the house efficient. The foundation, framing, insulation, air sealing, HVAC, ductwork, windows, ventilation, and water-management systems all need to work together.

Just as importantly, we don't ask homeowners to simply take our word for it. Our homes are independently tested and their performance is documented through nationally recognized programs and standards.

Every Two Structures home includes:

  • ENERGY STAR® certification
  • An independent HERS® rating
  • Blower-door and duct-leakage testing
  • Third-party inspections and verification
  • Participation in Oklahoma utility energy-efficiency programs
  • Construction practices designed for Oklahoma's climate

For us, building an energy-efficient home isn't about adding an upgrade package. It's part of how we build the home from the beginning.

Frequently Asked Questions

Do Energy-Efficient Homes Cost More to Build?

Often, yes. High-performance construction can require better materials, tighter construction tolerances, more attention to air sealing and insulation, properly designed mechanical systems, and third-party testing.

The important comparison is not simply the initial construction cost, but the long-term cost of ownership, including energy use, comfort, durability, and maintenance.

What Is a Good HERS Score for a New Home?

The HERS® Index uses a reference home based on the 2006 International Energy Conservation Code as its benchmark, with a score of 100 representing the HERS Reference Home. A score of 0 represents a net-zero-energy home. The lower the score, the greater the modeled energy efficiency relative to that reference home.

Two Structures Homes typically achieves HERS scores between 40–47, providing independently verified performance substantially better than the HERS Reference Home.

Are Energy-Efficient Homes More Comfortable?

Typically, yes. A well-designed building envelope, proper insulation and air sealing, correctly sized HVAC equipment, sealed ductwork, and balanced airflow can help reduce drafts, hot and cold spots, and unwanted temperature swings.

For homeowners, that means energy efficiency isn't just something measured on a report—it can also be something they experience in the comfort of the home.

What’s the Difference Between Energy Star® and HERS?

ENERGY STAR® certification verifies that a home meets specific energy-efficiency requirements established by the U.S. Environmental Protection Agency and has completed required inspections and testing.

A HERS® rating provides a numerical score representing the home's modeled energy performance compared with the HERS Reference Home.

Together, they provide two different forms of third-party verification: certification to an established standard and a measurable energy-performance rating.
