He's trying to get credit for... not giving the top floor of a student doorm to rich people as a penthouse?
Are there other student dorms where the top floor is given to rich people for penthouse condos?

In this case it would be instead of having premium student dorms on the top floor for wealthier students, or rooms for the student dorm administrators, instead every student gets access to that penthouse common space.
I've never seen any dorms with "premium" student housing, let alone mixed in the building. There are certainly (especially older) dorms with more desirable rooms, but they were never "premium" or unavailable to any student.
