"Other Non-structural Elements" covered elsewhere??

The project we are working on is looking to take advantage of MRc1.2 Building Reuse. However, this credit seems to only cover the basic non-structural elements - walls, floors, ceiling etc. Is there any credit that covers "other non-structural elements," including electrical, mechanical and plumbing components? Our project retained a large amount of electrical fixtures and wiring, and spent very little in purchasing new fixtures. I am not aware of any credit that would cover these other elements in the same way that MRc1.2 does. Or would this be something we should pursue as “Innovation in Design”? Any input would be helpful. Thanks!
