ENERGY STAR NextGen: 5 Requirements for Climate-Friendly Homes

Building on the 25-year foundation of the ENERGY STAR Residential New Construction program, the EPA is gearing up to launch a new certification program for efficient single-family and multifamily homes: ENERGY STAR NextGen™ Certified Homes and Apartments. Based on initial energy and emissions modeling, ENERGY STAR NextGen certified homes will achieve an average of 47% greater carbon savings than homes built according to 2021 residential energy code.

In this episode, Robb chats with two members of EPA’s ENERGY STAR Residential Branch, Asa Foss and Elliot Seibert, about what home builders, raters, and buyers can expect from ENERGY STAR NextGen and its electric-forward—not all-electric—focus. They discuss each of the program’s requirements and the rationale and goals behind them.

Asa Foss joined EPA’s ENERGY STAR Residential Branch in 2020, where he’s managing ENERGY STAR NextGen, an operational decarbonization-focused new construction specification. He’s been in the residential efficiency industry since the early 2000s, including a decade at the U.S. Green Building Council where he was responsible for the development of the LEED for Homes rating systems. He renovated and lives in a designated-historic ENERGY STAR and LEED Platinum certified rowhouse in Washington, DC.
