We have a client who owns several buildings built 100+ years ago. He currently would like to remodel and certify the 4 office suites in one of the buildings under LEED CI. The remodels would be done and certified one at a time until all 4 are complete. The building itself is not certified, but he would like to get it certified upon completion of the interior projects. My question is - is this feasible or must the building first be certified under EBOM? Thanks in advance for your answers.
