To earn the ENERGY STAR under the ENERGY STAR for Homes Version 2 Guidelines, homes must be one of the following:
- Single–family homes; OR
- Units in multi–family buildings with 3 stories or less; OR
- Units in four– or five–story multi–family buildings where: 1) The structure is permitted as residential by the local building department; and 2) each residential unit has its own heating, cooling, and hot water systems, separate from other units. The phrase, "permitted as residential structures," is intended to represent units that either fall within the scope of the residential building energy code or are permitted as having a residential use–group, even under conditions where the commercial building energy code applies; OR
- Units in multi–family buildings that are located on top of commercial spaces (e.g., retail, restaurant, etc.), even if the structure is permitted as commercial, as long as: 1) the entire structure is five stories or less; and 2) each residential unit has its own heating, cooling, and hot water systems, separate from other units.
Select the core energy efficiency measures
There are two paths to qualify a home to earn the ENERGY STAR. Both paths require verification:
Complete the Thermal Bypass Inspection Checklist
Both the Performance and Prescriptive Paths require the Thermal Bypass Checklist. The Thermal Bypass Checklist is a comprehensive visual inspection of building details where thermal bypass, or the movement of heat around or through insulation, frequently occurs due to missing air barriers or gaps between the air barriers and the insulation.
�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.
