As part of the April 2016 addenda release, USGBC introduced two LEED Interpretations that allow projects to leverage their DOE Zero Energy Ready Home and EPA Indoor airPLUS labels to earn points toward LEED v4 certification under LEED v4 BD+C: Homes.

  • Interpretation 10431 lists the LEED v4 credits and prerequisites a project earns when they receive the DOE Zero Energy Ready Homes (ZERH) label.
  • Interpretation 10436 lists the LEED v4 credits and prerequisites a project earns when they receive the EPA Indoor airPLUS (IAP) label. (A requirement of the DOE ZERH program is to earn the IAP label.)

By earning these labels, projects can be awarded a minimum of 26.5 points in LEED v4 BD+C: Homes, as well as most prerequisites in the Energy and Atmosphere and Indoor Environmental Quality credit categories. Additional points can be earned by having a HERS Index of 56 or better. Projects must earn at least 40 points to meet the LEED certification at the Certified level.

According to the U.S. Department of Energy, “A DOE Zero Energy Ready Home is a high-performance home which is so energy-efficient that a renewable energy system can offset all or most of its annual energy consumption.”

Credit-specific details

Projects that earn DOE ZERH meet the following LEED v4 Homes credits and prerequisites:

Projects also meet the requirements of all credits and prerequisites deemed equivalent to the EPA Indoor airPLUS program, which include:
