The climate zone is used to determine the appropriate construction sets per ASHRAE 90.1. There is not a distinction in ASHRAE 90.1 between 3B and 3B-Coast.
From the prototype model report: U.S. Department of Energy Commercial Reference Building Models of the National Building Stock
"We selected a revised set of locations as a balance of the representativeness of the climate and the number of buildings in each climate zone (see Table 2). Two locations were selected for climate zone 3B because they represent different climates within one zone, which is evident from the reference building model energy simulation results. These subclimate zones are designated as “3B-CA” for the California coast and “3B-other” for the remaining part of climate zone 3B."
