Hi all,

We are embarking on our office's first LEED Commercial Interiors project. The existing envelope received 2009 v3 LEED Gold for Core and Shell in 2014. Will it be acceptable for us to reuse pertinent documentation for the new tenant improvement? There seems to be a number of points that overlap the two rating systems. Also, the original project included a tenant improvement in approximately a total of 30% floor area of the 1st floor of a two-story building. Seemingly, we have the option of pursuing two separate CI projects or grouping them together as one. There is one owner and the interior existing walls clearly delineate the spaces. Is it correct that we have both of these options? If we pursue one project, will it be acceptable to exclude the existing tenant-improvement floor area?

Thanks for any help you can provide.
