definition of work room

If it looks like a duck and quacks like a duck, it must be a duck. I think your instincts are right. Even though the rooms are labeled “Workrooms” on the plans, if they are furnished like open offices with desks or workstations that suggest that occupants will “perform distinct tasks from one another,” the rooms are "individual occupant spaces" that match the IEQ Matrix “Open Office” designation. By contrast, since the IEQ Matrix identifies Library & Museum Workrooms as “multi-occupant spaces,” one would expect them to be furnished to allow occupants to congregate and “pursue overlapping or collaborative tasks.” This suggests open worktables or counters with supplies and equipment to support the anticipated types of tasks. In a library, these might include printing, sorting, labeling, packing, binding, book repair, etc.
