While working on a Leed certificate Project, Me and my team stumbled against a interpretation issue. Our Project is located on a historic site and also correlates to a historic building that is going to be preserved. We have the documentation proving that the Project is placed inside a historic site and also the documentation from a local equivalent for U.S. National Register of Historic Places. The question is, is there a percentage of preservation that has to be maintained, or being on a historic site and also declared a monument is valid to obtain the credits?
