Multifamily Audits

 
Where multifamily dwelling units represent more than 20% of a Grantee’s building type, DOE requires approval of the multifamily audit and procedures.  For Grantees that do not have DOE approval for multifamily unit audits, Grantees shall describe in their State Plans the approach that will be taken to ensure that the eligible occupants of multifamily dwellings receive appropriate, cost-effective weatherization services.
 
For energy audit purposes, DOE considers multifamily buildings to be those containing five dwelling units or more. Approved single-family energy audits can be used in buildings with one to four dwelling units. As approved by DOE on a case-by-case basis, certain single-family energy audits may be used in multifamily buildings containing up to 25 individually heated and cooled dwelling units.  Unlike single-family and mobile homes, DOE has not developed a multi-family audit but instead relies on commercially available tools to meet the needs of the Weatherization Assistance Program.
 
For small multifamily buildings, less than 25 units, where the units are individually heated or cooled, DOE has previously reviewed and accepted for use in the Weatherization Assistance Program the following software: AKWarm*, EA-4*, EASY 2.1*, HomeCheck*, NEAT, REM/Rate*, and TREAT.

* separate audit tools are necessary to evaluate mechanical measures
 
For small multifamily buildings, less than 25 units, with buildings containing central heating and cooling systems, DOE has previously reviewed and accepted for use in the Weatherization Assistance Program the following software: EA-Quip and TREAT.
 
For large multifamily buildings, more than 25 units, DOE has previously reviewed the accepted for use in the Weatherization Assistance Program the following software: EAQUIP and TREAT.
