Products applied offsite and non-Occupied spaces

According to the credit language you must include building enterior and exterior materials that are on-site, wet-applied, full-spread products:  - The building interior is deined as everything within the waterprooing membrane.
- The building exterior is deined as everything outside and inclusive of the primary and secondary weatherprooing system, such as waterprooing membranes and air- and water-resistive barrier materials. So answer to you last question - yes, products applied within non-occupied spaces such as MEP rooms and etc. are subject to the credit regulation since it is an interrior space.  Answer to your first question (regarding off-site applied paints) - no, it's not included. I.e. if you received a product (steel construction or other material - as long it is not furniture) at which paint or coating with VOC was applied (or you even don't know type of coating and if it contains VOC at all) and it is installed internally - it's not a subject to the credit regulation. Proof - pages 666-667 of Refguide that states that such products as "factory-inished metal wall products" & "Factory-inished metal ceiling products" are exceptions.    Note, that such things as partial height or floor-to-ceiling cubicle panels that are manufactured of-site are stil considered as furniture and fall under credit scope.
