Why we’re the #1 energy-efficient national homebuilder.*
When you’re buying a new home, there are probably lots of items on your checklist. A floor plan with enough bedrooms, generous storage space and maybe a yard for the kids to play. But sometimes it’s the things that you don’t see that can make the biggest difference — and that’s where energy efficiency matters.
Building more efficient homes doesn’t happen overnight — it takes time and dedication. And we’re proud to share that our enduring commitment to deliver communities that focus on sustainability has made us the #1 energy-efficient national homebuilder.*
How did we achieve this status? It’s all about the Home Energy Rating System (HERS®) Index scores. Let’s take a closer look.
Understanding Home Energy Rating System (HERS) Index scores.
**A scoring system established by RESNET in which a home built to the specifications of the HERS Reference Home (based on the 2006 International Energy Conservation Code) scores a HERS Index of 100, while a net zero energy home scores a HERS Index of 0.
The Home Energy Rating System (HERS) is the homebuilding industry’s benchmark to measure and calculate a home’s overall energy efficiency. And it’s all about the numbers — the lower, the better. KB Home’s average HERS Index score is 50, and when you realize that a home built to the specifications of the HERS Reference Home gets a HERS Index score of 100, and the average HERS score for used homes is 130, that’s pretty fantastic.
Your new KB home is TWICE as energy efficient as a HERS Reference Home and 61% more than a used home, numbers that can potentially add up to big savings. Because you’ll spend less on utility bills, you can use the money you save toward something you really want. Plus, a home with lower scores and higher energy performance is better for your well-being as well as the environment — and that’s good for everyone.
The KB Home Energy Savings Comparison™
The proof is in the numbers, and we make it easy to see the difference. For instance, when you’re viewing floor plans on our website, each one features an Energy Savings Comparison (ESC) so you can see upfront how much you could save with our energy-efficient homes. Simply put, the ESC offers a handy estimate of monthly energy costs, as well as estimated monthly savings when compared to a typical used home.
Additionally, there’s a slider that calculates your estimated savings over a period of time in your new KB home — one month, one year, 10 years and 30 years. When you review the numbers spanning the short and long-term, the results can be quite significant.
Low HERS Index scores and ENERGY STAR® certified homes.
Achieving a certain HERS Index score is also a requirement to deliver an ENERGY STAR® certified home, which is specifically built with materials and construction techniques that lower the cost of ownership. ENERGY STAR certified homes are also designed to be healthier, more comfortable and better for the environment than new homes without certification.
We’re also happy to share that we were the first builder to make every home we build ENERGY STAR certified, a standard of energy performance achieved by fewer than 10% of new homes in America — KB has also built more ENERGY STAR certified homes than any other builder.
We’re here to help.
We know you probably have lots of questions when it comes to finding a home that’s just right for you — from construction materials to floor plans. And we’re here to help, so you better understand just what to expect and enjoy when you build a new home with us.
*Based on an internal compilation of the nationwide average of publicly reported HERS Scores from 06/21 through 09/21 among large production homebuilders. These are the top 20 U.S. homebuilders ranked by number of closings on the most recent annual Builder Magazine Builder 100 list that Builder Magazine identifies as operating in at least two regions (excluding any company primarily operating a single-family rental, build-on-your-lot or a manufactured home business, or operating as a nonprofit organization).
