How Heim Builds Energy-Efficient Homes That Last for Generations

As fall settles across Oklahoma and cooler air begins to creep in, homeowners start thinking about warmth, comfort, and inevitably energy bills. At Heim Custom Homes, this is the season when we’re reminded why we build the way we do. Every stud, seal, and system is part of a bigger story: one about building energy-efficient homes that perform beautifully all year long and stand strong for generations.

Our approach to sustainable home construction isn’t a trend. It’s a tradition rooted in care, craftsmanship, and forward thinking.

Built for Oklahoma’s Changing Climate

Oklahoma weather can be unpredictable, with tornadoes, sweltering summers, icy winters, and everything in between. To keep your home comfortable in every season, we start with the essentials: airtight construction, high-performance insulation, and thoughtful design.

Smart Insulation from the Ground Up

Insulation isn’t just about warmth; it’s about efficiency and longevity. We use the most optimal methods for this to create a consistent thermal barrier that minimizes air leaks. This means your home stays cooler in July and warmer in January without overworking your HVAC system.

Our approach aligns with the U.S. Department of Energy’s Energy Saver Guidelines for Efficient Home Design, emphasizing the proper sealing of gaps and insulation in attics, walls, and crawl spaces to achieve maximum energy savings.

High-Performance Windows and Doors

Windows and doors are among the critical areas where homes can lose energy. That’s why at Heim Custom Homes, we incorporate Low-E windows. This UV-protective glass is designed to reduce energy costs as part of our standard offerings. 

Why Low-E & High-Performance Glass Matter

We partner with trusted suppliers to offer high-performance window models that help reduce solar heat gain in summer and retain warmth in winter. These windows complement the other energy-saving systems in your home, insulation, HVAC, and air sealing, to enhance overall performance.

Rather than making absolute claims about efficiency percentages, we lean on real-world standards and trusted practices. Efficient window upgrades, properly sealed and installed, consistently play a major role in lowering energy use.

Smarter Systems, Healthier Homes

An energy-efficient home is more than just a sealed envelope. It’s an ecosystem, one where HVAC, appliances, and controls work together so comfort, air quality, and efficiency stay in balance.

HVAC & Indoor Air Quality

We specify high-efficiency HVAC systems from trusted partners like Lennox, sized and tuned for your home. Lennox makes people feel comfortable in their homes. They make the air cooler, warmer, drier, cleaner, and better with innovative systems that are exceptionally quiet and energy efficient. All brought to you by dealers with the expertise and resources to serve you in the best possible way.

Ventilation strategies are tailored to the home and code requirements, and we combine tight construction with deliberate fresh-air planning to keep indoor air healthy.

Energy-Smart Appliances

We help you choose premium appliances that complement your home’s design and fit your family’s lifestyle by working with trusted partners like Electrolux and Ferguson. Many of our homeowners appreciate high-performance options that balance convenience, quality, and design. Electrolux offers thoughtfully crafted, luxury appliances developed through extensive consumer research to deliver performance that exceeds expectations, while Ferguson specializes in bringing kitchens and bathrooms to life with stylish, durable fixtures that elevate everyday living.

The goal is straightforward: to achieve substantial and reliable performance with lower long-term operating costs.

Design That Works With Nature

At Heim Custom Homes, energy efficiency begins long before construction starts. Every home is designed with intention—planned to make the most of your land, natural light, and surroundings. Before we pour a foundation, our team carefully studies your property’s layout, sun exposure, and prevailing conditions. This helps us design a home that works in harmony with Oklahoma’s climate, reducing energy demands while maximizing comfort and livability.

Thoughtful Design for Lasting Efficiency

• Natural Light & Orientation: Our homes are designed to bring in light where it’s needed most. Strategic window placement and room orientation help manage indoor temperatures and reduce the need for artificial lighting throughout the day.
• Shade & Protection: Features such as porches, covered patios, and roof overhangs are more than beautiful architectural details—they also help shield the home from direct sun, keeping interiors cooler and more comfortable year-round.
• Comfortable Living, Naturally: Smart floor plans and airflow-conscious layouts help maintain comfort across the seasons. We pair these design strategies with high-quality construction materials and insulation to ensure each home performs efficiently for generations.

At Heim Custom Homes, energy efficiency isn’t an add-on—it’s built into the way we design and construct every home. It’s how we create timeless spaces that are as comfortable and efficient as they are beautiful.

Quality Materials for Generations

Sustainability means more than energy savings; it means longevity. A truly energy-efficient home is one that doesn’t need to be replaced or repaired prematurely.

We source durable, low-maintenance materials—from siding and roofing to flooring and cabinetry—that stand up to time, weather, and daily family life. Every finish, fastener, and fixture is chosen with care, ensuring that your home performs as beautifully in 30 years as it does the day you move in.

Our craftsmanship reflects the values that define our work: honesty, quality, and care. When you walk into a Heim home, you can feel it.

Preparing for Winter: Why Fall is the Perfect Time

Fall is more than a season; it’s an opportunity. Whether you’re planning to build your dream home or exploring upgrades for your current one, this is the ideal time to focus on energy efficiency before heating costs rise.

Building a custom home this season means we can integrate the latest in insulation, window technology, and smart systems. So by next winter, your new home will be ready to keep you cozy without compromise.

If you’re already a homeowner, we recommend checking your insulation levels, sealing air leaks, and considering energy-efficient upgrades. Small steps today can lead to major savings tomorrow.

Our Promise: Efficiency Without Sacrifice

Every Heim home is a reflection of the people who live in it, unique, resilient, and built to last. We don’t take shortcuts because we know your home isn’t just a structure. It’s where memories are made, families grow, and legacies begin.

We build homes that feel good to live in and good to live with. That’s the Heim difference.
