Hawaii ENERGY STAR Version 2.5 Guidelines

Should I use the Version 2.5 guidelines?

• Homes permitted between April 1, 2012 and July 1, 2012 must be certified under the Version 2.5 Program Requirements for Hawaii.

For more information about the transition from the BOP to Version 3, including the transitional Version 2.5 guidelines, see the Transition Timeline for Hawaii.

How to Qualify a Home

Select the core energy efficiency measures

There are two paths to qualify 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 that is equivalent in performance to the ENERGY STAR Reference Design home.

• ENERGY STAR Version 2.5 Program Requirements for Guam, Hawaii & Puerto Rico (216KB) — This document defines the core energy efficiency specifications for both the Prescriptive and Performance Paths under Version 2.5 of the program.

Complete inspection checklists

The Version 2.5 Program Requirements for Hawaii require the completion and enforcement of four inspection checklists:

• Thermal Comfort System Rater Checklist
• HVAC System Quality Installation Rater Checklist
• 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. See the ENERGY STAR Inspection Checklists for Guam, Hawaii & Puerto Rico (773KB).

While the inspection checklists must be completed under Version 2.5, certain allowances are made that will help partners successfully transition from the Version 2 to 3 guidelines. To see these allowances, read the ENERGY STAR Version 2.5 Program Requirements for Guam, Hawaii & Puerto Rico (216KB).

EPA has developed guidebooks on the HVAC System and Water Management System checklists to explain the rationale behind each item.

Sampling Protocol

'Sampling' allows builders who have demonstrated an ability to consistently meet the ENERGY STAR guidelines to minimize production interruptions and verification costs. For more information, see Chapter 6 of the Mortgage Industry National Home Energy Rating Standards .

Policy Changes and Clarifications

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.

Training Requirements and Resources

Version 3 includes new and more rigorous requirements for builders, raters, and HVAC contractors. EPA requires that they each complete training on Version 3 to promote successful adoption and has created a number of resources to assist them in understanding the guidelines. Learn More.
