Generally, it is not possible to benchmark multiple buildings as a single entity on Portfolio Manager for Case 1 or for Case 2. Each building must be separately benchmarked as a standalone entity according to either Case 1 or Case 2 depending on the space type associated with each building. USGBC’s Application Guide for Multiple Buildings and On-Campus Projects is a good resource to reference in this type of scenario.

Yes, international projects that are comprised of ratable space under Energy Star must still pursue the EAp2/EAc1 via Case 1.

The updated Case 2 calculator (see resources section) uses Labs21 to facilitate benchmarking for buildings with laboratory spaces. The calculator includes specific directions to walk you through the process.

No, but it might not hurt. Items commonly included in the credit are general construction adhesives, flooring adhesives, fire-stopping sealants, caulking, duct sealants, plumbing adhesives, and cove base adhesives. If your project doesn't report using one or more of these, your LEED reviewer might ask you to verify your list of documented items, to check that something wasn't inadvertently omitted.

All adhesives and sealants used on site within the weather barrier (including flooring adhesive) need to be included. 

Yes, grout and caulking need to be included. There is no specific category for them, however. Projects have successfully used ceramic tile adhesive—VOC limit 65g/l—and Architectural Sealant—VOC limit 250 g/l—successfully, the latter being especially appropriate if you are using a product other than ceramic tiles. Since most mortars, grouts, and thinsets are largely cementitious, with inherently low VOC content, they will comply under most categories, anyway. Choose a logical category and explain it in a narrative if necessary.

This is usually found on a product cut sheet or MSDS. If you cannot find the information, contact the manufacturer or technical services for the product and they should be able to provide this number for you. The method for dermining this is explained in SCAQMD Method 305-9, Determination of (VOC) In Aerosol Applications.

All projects use the building site area for the density radius calculation.

The SSc2 Option 2 residential requirements for NCv2.2 and NC 2009 are for projects to locate in an area within one-half mile of an existing, not planned, residential district featuring a density of at least 10 units/acre. Projects should not depend upon planned residential areas for credit compliance, as this does not represent existing infrastructure in most cases. Projects not meeting these requirements but believing they meet the credit intent will be considered on a case-by-case basis and must submit a project-specific CIR to determine their compliance potential.

Maybe. Language in the Reference Guide is not crystal clear on this point, and some comments from project teams indicate that campus projects should demonstrate that services are open to the public. For LEED documentation purposes, LEEDuser recommends avoiding relying on such services, or seeing a CIR to be sure of your approach.
