I have an existing building that is mainly an 9000 m2 office building. some of the office floors are still not occupied around 2000m2 "core & shell space". can I still register this building for LEED EB O&M? and how would I deal with the core & shell space?
Razan, as long as you meet the occupancy requirements (see MPRs) you can register under LEED-EBOM. Dealing with the CS space is going to be credit-specific to some extent—I'd suggest posting specific questions under those credits.
