How to Certify a Home

Complete inspection checklists

The Version 2.5 Program Requirements for Guam, Hawaii, & Puerto Rico require the completion of four inspection checklists:

  • HVAC System Quality Installation Contractor Checklist
  • Water Management System Builder Checklist

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 2.5 must complete.

While the inspection checklists must be completed under Version 2.5, certain allowances are made that will help partners successfully transition to Version 3 Program Requirements. To see these allowances, read the ENERGY STAR Version 2.5 Program Requirements for Guam, Hawaii & Puerto Rico PDF (216KB).

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.
