I am working on a project that has the client moving into a new building from their existing space. We are proposing to use a casework system that will use a combination of new material and salvaged/repurposed material. The casework system will be composed of new FSC plywood frames (top, bottom, sides and back). The horizontal shelves will be the clients workstation tops cut down to the necessary widths. The workstation tops are existing in the clients current space. The tops will be removed from their current location, cut down on site and then reinstalled in the new office space. Would only the new material area count in the building reuse 1.2 credit and the salvaged/repurposed top material area count in the material reuse 3.2 credit?

The way to think about this credit is do a QTO of the furniture and finishes of the existing building prior to renovation and compare it to the QTO of all unaltered furniture and finishes in the renovated floor plans. For example, say your QTO of the interior space prior to renovation was 10,000 linear foot. Then, after you've redesigned the space, you show that 7,364 linear feet were unchanged (meaning you do not plan to use a different finish, nor do you plan to remove/change the permanent furniture systems, interior walls, etc). Therefore, 73.6% of your new design would be "maintained", earning 2 points in MRc1.2. This credit has nothing to do with reusing salvaged material, which is addressed in the materials reuse credit, as you suggested. The intent of this credit is to use what's there and minimize interior renovation.
