The credit requirements state: Achieve a HERS index rating at or below the HERS index target (or USGBC-approved equivalent for projects outside the U.S.) or meet the requirements of the ENERGY STAR for Homes version 3 Prescriptive Pathway, which includes meeting or exceeding all components of the ENERGY STAR Reference Design.

International projects have a better chance with the prescriptive pathway of the Energy Star program. However, in v2008 there is a restriction for projects with only heating or only cooling, which must to follow the performance pathway. It makes me wonder if there is any restriction in v4 for the following cases:

  1. Projects with only heating
  2. Projects with only cooling
  3. Projects with both heating or cooling
  4. Projects with pools, spas, heated driveways, and heated garages
