ENERGY STAR Homes National Program Requirements, Version 3 (Rev. 08)
To earn the ENERGY STAR, a home must be certified under Version 3 of the program requirements, unless it is located within a U.S. state or territory utilizing a regional specification. Working with a Home Energy Rater, builders configure the preferred set of energy measures for their home and verify that the resulting Energy Rating Index meets or exceeds the ENERGY STAR Energy Rating Index Target. The National Program Requirements contain more information about how the target is defined and the typical measures used to meet this target.
