CI-v4.1 BPDO - Environmental Product Declarations and Material Ingredients

BuildingGreen has definitions:

enclosure

The exterior plus semi-exterior portions of the building. Exterior consists of the elements of a building that separate conditioned spaces from the outside (i.e., the wall assembly). Semiexterior consists of the elements of a building that separate conditioned space from unconditioned space or that encloses semi-heated space through which thermal energy may be transferred to or from the exterior or conditioned or unconditioned spaces (e.g., attic, crawl space, basement).

I would not consider ceiling panels in this definition.

structure

Elements carrying either vertical or horizontal loads (e.g., walls, roofs, and floors) that are considered structurally sound and nonhazardous.

I would assume raised access flooring could be considered structural since it would have to carry the load of furniture and people, whereas I would not consider floor covering as structure.

I'd recommend substituting the v4.1 credit path.

LEED v4.1 removed the limitation listed in your post.
