I am working with a client to determine if they will be able to achieve certification using LEED EBOM. The building is connected to a district chilled water plant where R-11 is used. My client purchases the water, they do not own the plant, therefore have no influence on chiller phase-out or replacement. Is there any guidance available on how to meet this prerequisite under these circumstances?

If we pursue the economic analysis option, should would be considering stand alone refrigeration equipment for this building replacing connection to the district plant? An analysis for replacing chillers does not seem to apply to my client since they would not own the chillers or finance the replacement.
