For the lighting credit you need to have individual controls at 90% of patient positions.  LEED defines patient positions as:

A patient bed, infusion chair, recovery room bay, or other location where a patient receives clinical care

Would you classify a drawspace (where they take blood samples) as a location where a patient receives clinical care?  I wouldn't think so because they're not getting care, they're just getting their blood taken and only for a couple of minutes.  Thoughts?
