NC-2009 EAp2:Minimum Energy Performance

Process outside buildings

Hello, Regarding a campus project: We have several buildings (11 small ones) within one campus and several processes going on within the campus, but outside of any building. Some of these processes are independent, but others (i.e. a water treatment plant) serve several buildings, they have pumps and other electrical equipment (but they are all physically outside any building). How is the energy of these systems accounted for in the several buildings (some of them with their own LEED Certification, some others not pursuing LEED Certification)? We consider that the energy consumption of each building (from each process) should be assigned to each building, knowing the demand of each of them and estimating the fraction that each will consume. Is this approach correct? Thanks!

It all depends on how you are pursuing LEED Certification. Typically if dividing up the campus and pursuing projects individually the rule to follow is all the energy use within the project boundary.

Thanks for your reply, Marcus. We are going for the Campus Program, most of the buildings will pursue an individual Certification and maybe some of them a Group Certification (it is still in a schematic phase) within the Mastersite. If a certain system is within the project boundary of Building A, but will be serving Building A, B, and C (each with its own Certification) does the energy consumption get divided between the 3 buildings (each with its respective use)?

It is hard to say without knowing the specifics. The water treatment plant would only need to be accounted for if it is within one of the project boundaries. Since it is a process it would be modeled identically and could possibly be divided among the projects or included in just one depending on the boundaries.
