I'm working on an assisted living facility that will have laundry machines in just a few of their residential units, but generally have a central laundry facility for the building. Would the water for the res laundry units count as process water and thus need to be in the 80% calculation?

I think they would need to be included but depending on the scale of the project and other laundry facilities perhaps those obviously would not account for 20% of process water. We have a dorm project with laundry in two hall director offices as well as central laundry facilities for students. We have design comments back from GBCI that ask for accounting of these as well as janitor sinks as part of building process water. We were originally trying to get this for process water by metering evaporative cooling makeup water but don't have a strategy for proving it makes up 80% of the total process water. I will be interested to hear how you approach this.

Are dishwashers in tenanted office areas considered as "process water" and need to have separate meters or are these considered as "Indoor plumbing fixtures and fittings"?

Erkki, from the reference guide language, dishwashers are considered process water; they wouldn't necessarily have to be separately metered if your other water loads made up 80% of the total process water.
Per the credit language, "Other process water. Meter at least 80% of expected daily water consumption for process end uses, such as humidification systems, dishwashers, clothes washers, pools, and other subsystems using process water."
