Permanent Exhibit Vs Temporary Exhibit

Ralph – I presume that you posted this question in the NC IEQc4.4 forum because NC-IEQc4.4 excludes materials considered fixtures, furniture, & equipment (FF&E), as opposed to permanent, base-building elements. You seem to be asking whether this exclusion applies to “non-permanent” exhibit elements. Similarly, credits MRc3 through MRc7 evaluate sustainable criteria of permanently installed, base-building materials. Only under certain circumstances may projects include temporary materials or furniture specified in CSI Division 12. Does your inquiry extend to MR credits as well? In any case, no specific “time period” defines “permanent.” How the exhibit scope is being purchase, what it includes, and when the build-out occurs may tell you whether and how to include exhibit elements in various LEED-NC credits.
