Homebuilder KB Home achieved several sustainability goals, including the construction of its 200,000th ENERGY STAR® certified home.

The company announced its achievement of an average Home Energy Rating System® (HERS) Index score of 45, among the lowest in the industry, a year ahead of the goal it set in 2020. This means that a 2024 KB home is 55% more energy efficient than a typical home built as recently as 2006.

KB Home also helped its customers save an estimated $1.3 billion on their utility bills since 2000. A KB home built in 2024 can deliver to its homeowners an estimated average of $1,800 annually in utility savings compared to a typical resale home.

Details were published in its 2024 Sustainability Report.

“KB Home was founded with the goal of making first-time homeownership more affordable through innovative thinking. For the last 18 years, one of the primary ways we have done that is through our expanding dedication to sustainability as a means to build a better home that can be more affordable,” said CEO Jeffrey Mezger in a statement. “We are proud to lead the industry in building high-performance homes that help to lower the total cost of homeownership and sustain the American dream.”

In 1976, KB Home introduced its first energy-efficient homes, setting the stage for future sustainability initiatives. Its first ENERGY STAR certified home was built in 2000, and in 2008, the company made a broad commitment to design all its homes to be ENERGY STAR certified. 

In 2022, KB Home became the first national builder to adopt the U.S. Environmental Protection Agency’s (EPA) highest water efficiency standards in drought-prone regions and pioneered two all-electric, solar- and battery-powered microgrid communities. 

KB Home is the only national builder to have earned awards under every EPA homebuilder program, including ENERGY STAR, WaterSense and Indoor airPLUS.
