Hello!  Can you provide me with a list of all building names?
select name from building
Great!  Can you update the list to show the number of different institutions in each building?
select t1.name, count ( * ) from building as t1 join institution as t2 on t1.building_id = t2.building_id group by t1.building_id
Yes!  I want to know the name of the tallest building please.
select name from building order by height_feet desc limit 1
