Applicant Tools & Resources


  • All applicants for the Comprehensive NOFO must either submit Benchmarking Data through EPA's Portfolio Manager or the Multifamily Building Efficiency Screening Tool (MBEST). 
    • Benchmarking Resources Owners using Portfolio Manager benchmarking may use the posted resources, including instructions for inputting and sharing data, a sample tenant release for owners that cannot access whole-building data, and template RFPs for hiring a benchmarking contractor.
    • The Multifamily Building Efficiency Screening Tool (MBEST). Owners can apply for the Comprehensive NOFO through the MBEST set-aside (up tp 40% of funding put out through the NOFO) instead of submitting benchmarking data in Portfolio Manager. This tool was created in partnership with the U.S. Department of Energy and the Lawrence Berkeley National Laboratory to screen multifamily buildings and understand current opportunities for energy efficiency improvements.
