I recently completed this Pilot Credit and determined that our project meets Option 1 and possibly meets Option 2. My biggest concern with Option 2 is the requirement that structure and enclosure materials may not constitute more than 30% of the value of complaint building products. I am documenting this Pilot Credit for a major renovation LEED 2009 Core & Shell project, so a majority of construction materials are enclosure. Interior finishes make up a very small portion of the overall building; approximately 15%. I think USGBC should consider lifting the 30% requirement for certain project types.
