Multi-family residential buildings are currently not eligible to receive an Energy Star score in Portfolio manager. Also, they do not have data on national average EUI to use for comparison to show efficiency improvements. Does this mean that multi-family residential projects cannot get certified under the LEED-EBOM system since they cannot meet the prerequisite? Is there any guidance on what multi-family projects should do? Has anyone attempted this on another project. Any help is appreciated! Thanks.

Lance,
Have you tried the USGBC EAp2 Case 2 Calculator for buildings that aren't eligible for Energy Star? There is a "Lodging - Residential - Multifamily" space type avaialable there.
The link above didn't work for me just now, but you can also find the excel file linked at:

Lance...how big is your multifamily building? If there are four or more habitable stories, your building qualifies. As Tristan notes, you'd use the offline calculator to performance the energy benchmarking (which incorporates information from the DOE national residential building energy consumption survey - like CBECS but for residential).
If you do go forward with this project, know that there are several credits for which compliance in a multifamily building is not straight forward, and you should use GBCI customer service and/or CIRs to get as much advance clearance on alternative compliance paths as possible.
