the Building's Empty but the Lights are On

Since many offices are unoccupied for up to 14 hours a day, why are their lights still on at 11pm on a Saturday night? They are serving no purpose for anyone at that hour – so why are they still burning bright? When you are out in the evening, notice how many offices are brightly lit when the parking lots are empty. Notice that the parking lots are still fully lit too; but that's the subject for another post. Back to the lit building....Some people try to explain it by telling me "Those are Night Lights". But, they should be called “Occupancy Lights”. The real purpose of these lights is to provide for basic lighting when the building is occupied. They provide basic fill lighting and light hallways to exits. So, again, why are they still on when the building is empty? This is so obviously silly; you can't help but wonder why. Why are we so blatantly wasteful? Is this waste really intentional or are we just en mass forgetful? Maybe we all just can't remember to turn the lights out. OK, I'm having a little fun here, but seriously folks?
