Energy Performance Score

For just three letters, EPS^TM says a lot about a home. This energy performance scoring tool highlights the benefits of energy-efficient newly built homes and also stands as a symbol of superior quality. EPS rated homes are built well above code, and each is thoroughly tested so you can be confident in how they’ll perform.

What’s in a Score?
With EPS, you’re able to compare how similar-sized homes use energy, review the features that make energy-efficient homes stand out, and even see your estimated utility costs before you buy. To determine the score, a third-party verifier analyzes the home’s features and construction techniques and tests performance factors such as air leakage and duct tightness. Scores range from zero to 200, with zero being the most efficient.

Built Better
Not just any home earns a score. EPS rated homes are built with energy-saving features such as advanced framing, duct sealing, high-performance windows and insulation, energy-efficient appliances, heating and cooling equipment and more. It all adds up to top-quality homes that give you:

• Comfort in every room
• Consistent temperatures
• Fewer drafts and air leaks
• Long-standing durability
• Low energy costs
• Healthy indoor air quality

Want to Take Home Efficiency Even Further? Live Net Zero
There are energy-efficient homes, and then there are Live Net Zero homes. These are homes with the potential to produce as much energy as they use over the course of the year, making your energy consumption essentially zero. To qualify as Live Net Zero, a home must be built to perform at least 35 percent better than code—in some cases even higher depending on the location—and meet all requirements to earn a superior EPS. Email us for more information on Live Net Zero homes, and to find qualified builders in your area

EPS works with Accessory Dwelling Units
Interest in accessory dwelling units, ADUs, is rising fast as more and more homeowners see the value of having an extra living or rental space on their property. Because of their small size, ADUs can be built to use very little energy if you plan ahead. Talk to your builder about including energy-efficient features and getting an EPS for your detached ADU. You can also call 1.877.283.0698 or email us for more information.
