Inquiry

The building we are applying for LEED-EB certification is one of several buildings on a community college campus in Michigan. Currently, the college does not track purchases separately for each building because they typically make bulk purchases and distribute products to each building as needed. We have been able to determine the total purchases for the entire college. Using the size and population of the building we are submitting for certification, we would like to propose an alternative method of calculating the total purchases for our building. Would it be acceptable to the LEED-EB committee to determine the amount of purchases for our building based on a per square foot or per student basis? For example, if our building is 290,000 SF and the total of all buildings on campus is 1,200,000 SF, our building equals 24% of the SF. Based on this calculation, can we assume that 24% of all general purchases for the campus go to our building? (There are some specialty purchases for departments in proposed building we are able to track.) We are proposing to use this same strategy for the calculations required for Optimize Use of Alternative Materials, Optimize Use of IAQ Compliant Products, Sustainable Cleaning Products and Materials, and Additional Toxic Material Source Reduction in order to maintain consistency across the board. Please confirm this will be acceptable.
