I have a daycare facility with children from 0 yrs old to preschool age with one classroom for after school kids which I assume is older children. Realistically, I’d say all the children would not be using the janitors sink or the kitchen sink in the teacher/staff lounge or the showers. How do I go about taking that into accounting for that in the WE Credit 3 form for LEED-NC 2.2?

Also, there is a kitchen in the building with 1 worker. I know I need to add the hand washing sink but once again only 1 person will be using it and I assume it will be used more than once a day. How do I account for that?
