There are two paths to certify a home to earn the ENERGY STAR. The Prescriptive Path is based on a predefined package of improvements, while the Performance Path is based on a customized package of upgrades.
The Version 3 Program Requirements for Guam, Hawaii, & Puerto Rico require the completion and enforcement of four inspection checklists:
These checklists include building science practices that promote improved comfort, indoor air quality, and durability in certified homes. The Inspection Checklists document contains the four checklists that every home certified under Version 3 must complete. See the ENERGY STAR Inspection Checklists for Guam, Hawaii & Puerto Rico (777KB).
Technical guides for the ENERGY STAR Inspection Checklists are available at the Building America Solutions Center, created by the U.S. Department of Energy. These free guides replace EPA's Inspection Checklist Field Guidebooks and provide a wealth of building science and energy-efficiency information. They are intended to be aligned with, and used as a supplemental resource to, the Version 3 Program Requirements but do not represent the official policy of the ENERGY STAR Certified Homes Program.

EPA periodically makes policy changes and clarifications, typically in response to a unique situation within a particular climate zone, and shares frequently–asked questions. See Recent Policy Changes and Clarifications.
