Healthy New Construction Homes: 7 Features to Look For
Buying a newly constructed home in Oklahoma City? A beautiful kitchen and a great floor plan are important, but some of the most valuable features are the ones you cannot see after drywall goes up. Insulation, air sealing, ventilation, HVAC design, and moisture control all affect how a home feels and performs.
At Two Structures Homes, we encourage buyers to ask about those systems before choosing a builder. Use this seven-point checklist to compare new homes in Oklahoma City, Edmond, Deer Creek, Yukon, Mustang, and surrounding communities.
Healthy Home vs. Standard New Construction: What Should You Compare?
Building code establishes important minimum requirements. Some builders go further with higher-performance specifications and independent testing. Instead of assuming every new home is built the same way, ask for the details in writing.
| Feature to compare | What to ask a builder | Two Structures Homes approach |
|---|---|---|
| Insulation and air sealing | What R-values and leakage testing are included? | 2×6 exterior walls, enhanced insulation and air sealing |
| Ventilation | How does outdoor air enter and how is stale air exhausted? | Dedicated outdoor-air intake and specified exhaust systems |
| HVAC | Is equipment sized for this house? | Attention to equipment sizing, airflow, and sealed ducts |
| Moisture control | How are windows, walls, and drainage detailed? | Weather-resistive barriers, flashing, and moisture-management details |
| Verification | Are performance claims independently tested? | ENERGY STAR program participation and third-party HERS evaluation |
1. Insulation and Air Sealing That Work Together
Insulation slows heat flow; air sealing reduces uncontrolled air movement through gaps and penetrations. Both matter for comfort and energy use. Poor detailing can also contribute to condensation risks in certain assemblies.
Two Structures Homes commonly uses 2×6 exterior walls, R-23 wall insulation, R-38 attic insulation, and an enhanced air-sealing approach. Ask any builder not only what R-values are listed, but also how installation quality and air leakage are checked.

2. Intentional Fresh-Air Ventilation
As new homes become tighter, controlled ventilation becomes increasingly important. Cooking, showering, cleaning products, furnishings, and normal daily activities can introduce moisture and pollutants indoors.
Ask how outdoor air is supplied, how kitchen and bathroom exhaust is handled, and whether the systems are designed to work together. A fresh-air intake is not automatically the same as a balanced ventilation system.
Two Structures Homes includes a dedicated outdoor-air intake associated with the HVAC system and specified exhaust ventilation components. Buyers with particular air-quality concerns should discuss filtration and ventilation options during design.
3. Properly Sized HVAC and Effective Filtration
A bigger air conditioner is not necessarily better. Oversized equipment may run in short cycles and, in some conditions, remove less moisture than a properly sized system. In Oklahoma, cooling performance and humidity management deserve special attention.
Ask whether the HVAC contractor performs a room-by-room load calculation, how airflow is designed, what filter rating the system can accommodate, and how often filters should be replaced. A high-rated filter is useful only if the system can handle its airflow resistance and the filter is installed and maintained correctly.

4. Moisture Management from Roof to Foundation
Water is one of a home's most persistent long-term threats. Rain intrusion, plumbing leaks, condensation, and poor site drainage can damage materials and create conditions in which mold may grow.
Ask about window and door flashing, house wrap, roof and wall penetrations, grading, and exhaust fans in moisture-producing rooms. Proper installation and maintenance matter as much as product selection.
Two Structures Homes uses weather-resistive barrier and flashing details as part of its building-envelope approach. Read more about building for Oklahoma's climate.
5. Thoughtful Paint, Flooring, and Material Choices
Some paints, adhesives, flooring systems, cabinets, and manufactured wood products emit volatile organic compounds (VOCs). Emissions vary by product, and a low-VOC label does not mean that a material is free of all emissions.
Ask for specific paint and flooring product information and whether low-emitting options or third-party emissions certifications are available. Consider how the home will be ventilated during finishing and after move-in.
Two Structures Homes uses water-based interior paint and can discuss material selections with buyers who have particular preferences. For a deeper explanation and a real custom-home customer story, read Just Because It's New Doesn't Mean It's Healthy.
6. Windows and Advanced Framing Details
Window performance influences drafts, solar heat gain, comfort near glass, and the amount of work the HVAC system must do. Framing details affect how much space is available for insulation and how effectively the wall assembly performs.
Ask about low-E glass, window performance ratings, flashing, insulated headers, and thermal bridging. Two homes can look similar from the street while performing very differently behind the walls.

7. Independent Testing and Verifiable Performance
Marketing terms such as energy efficient and high performance are more useful when supported by measurable results. Ask whether the home receives a blower-door test, duct-leakage testing, insulation inspection, or third-party energy evaluation.
Two Structures Homes participates in ENERGY STAR residential new construction and the OG&E Positive Energy Program, with homes typically receiving independently verified HERS scores in the 40s. A lower HERS score generally indicates better modeled energy performance relative to the index reference home.
Important distinction: ENERGY STAR and HERS address energy performance and related construction practices; a HERS score is not a direct indoor-air-quality test or a guarantee of a healthy home. Learn about ENERGY STAR certified homes.
Questions to Ask Before Buying a New Construction Home
- What are the standard wall and attic insulation levels?
- Is the home tested for air leakage and duct leakage?
- How is outdoor air introduced and how are kitchens and bathrooms exhausted?
- How is the HVAC equipment sized for this particular floor plan?
- What filtration options are compatible with the HVAC system?
- How are windows, flashing, grading, and moisture control handled?
- Which paints, adhesives, cabinets, and flooring products are standard?
- Will I receive independent ENERGY STAR or HERS documentation?
A builder should be able to explain what is standard, what is optional, and what has actually been tested. Ask for written specifications rather than relying on broad promises.
Frequently Asked Questions About Healthy New Homes
Is every new construction home a healthy home?
No. New construction alone does not establish indoor air quality. Ventilation, pollutant sources, moisture management, filtration, material choices, and ongoing maintenance all matter.
Does an ENERGY STAR home have better indoor air quality?
ENERGY STAR includes building-performance requirements relevant to comfort and ventilation, but it is not a comprehensive indoor-air-quality certification. Ask which ventilation and material specifications apply to the particular home.
What is the most important healthy-home feature in Oklahoma?
There is no single feature. A coordinated approach to insulation, air sealing, ventilation, HVAC sizing, and moisture management is more valuable than relying on one product or upgrade.
How can I compare two builders?
Request written standard specifications and ask for test results where available. Compare the complete building envelope and mechanical systems, not only finishes and square footage.
