Looking for guidance on HVAC-only scope project.  We are preparing a proposal for an exsiting DoD facility on an Army Base.  The RFP requires minimum LEED Silver Certification (formal certification, not equivalency) in an "appropriate" LEED rating system.  Project scope consists of replacing all HVAC units in the entire facility (boilers, AHU's, RTU's, FCU's, exhaust fans,everything).  Work will be phased as portions of the building must remain occupied during the work.  Architectural scope is limited to ceiling removal & replacement and construction of a new penthouse to house a new air handling unit.  Replacement of HVAC systems should mean we are a "major renovations" project but I'm not sure if we would meet the minimum points required for a LEED-NC project and I am not sure that LEED-EBOM would be appropriate either as many of the points in this system are related to building operations (recycling, purchasing, waste management, etc) that would have nothing to do with our project scope.  Anybody have experience with this kind of situation?  Any guidance you can provide?
