ENERGY STAR Changes and Clarifications

Version 2.5 and 3

After extensive consideration, EPA is adjusting the overall implementation timeline of the ENERGY STAR for Homes program requirements and two specific items related to HVAC design. EPA believes that these changes will position the program for greater success in the long-term and better achieve its market transformation goals. Specific changes include the following:

 

  1. While all homes permitted on or after January 1, 2012 must still be built to the Version 3 requirements, EPA is allowing homes permitted in 2011 to continue to be qualified under the transitional Version 2.5 guidelines through June 30, 2012. Previously, homes permitted in 2011, but completed on or after January 1, 2012 would have also been required to be labeled using the Version 3 guidelines. 
  2. On the HVAC System Quality Installation Contractor Checklist, for homes with final inspection dates through 12/31/2012, loads and room-level design airflows shall be permitted to be calculated for the configuration that will result in the largest load when a house plan is built with multiple configurations (e.g., orientations, elevations, options). 
  3. On the HVAC System Quality Installation Rater Checklist, for homes with a final inspection date through 12/31/2012, Item 1.2.1 is permitted to be within +/- 5 degrees of the 1% and 99% ACCA Manual J design temperatures for the contractor-designated design location.  In addition, for each house plan with multiple configurations (e.g., orientations, elevations, options), the Rater shall confirm that the parameters listed in Items 1.2.2 - 1.2.6 are aligned with either: the rated home, or with the plans for the configuration used to calculate the loads, as provided by the contractor. 
  4. On the HVAC System Quality Installation Rater Checklist, homes with a final inspection date through 12/31/2012 are permitted to be qualified without enforcement of the pressure-balancing requirement in Item 2.8.
