Automatic shutoff system

We have a site with 3 product buildings and a small separate canteen building . We have done automatic light shut off for the production buildings during after hours and we want to know if we have to do the same for canteen also. It is a smaller building and anyway after evening tea (3.30 - 4.00PM) the people who operate the canteen closes it and go home. So automatic light switch of for that building doesn't seem like logical. I also have the same concern for a small storage area. This area is also rarely used. Please advise on this. Thank you.
