I am working on an ID+C Retail project at a shopping center and our team would like to pursue this Pilot Credit. Do we calculate only our Interior project's annual water budget, which only has interior water fixture uses, Or do we have to include calculations for the process water from the shopping center's central water cooling plant? 

The credit language states: "Purchase Water Restoration Certificates® (WRCs) to match the building’s annual water budget based on WE credit calculations (indoor, outdoor, and process (chiller, cooling towers, commercial kitchens, healthcare water systems as applicable) water use annual projections)"

and it has no different guidance for ID+C projects.
