In Which Sam Has a Brilliant Idea

I've just had a brilliant idea.

(note: I haven't really thought this through very deeply, but from where I'm standing...ok sitting, it seems pretty valid)

Schools and places of work should all be required to provide enough windows in any place where people study/work that there is no need for overhead lighting of any kind. On top of having more windows, schools and places of work should be required to not provide or install overhead lighting of any kind.

This would cut down on energy bills. It would expose people to more sunlight and help with depression issues as well as general well-being. It would make it impossible--well maybe not impossible but at least very difficult--to study/work at these places after the sun goes down. People would be forced to go home if they wanted to "get things done." As we all know, it's impossible to be school/work productive at home, so productivity during the sunlit hours of the day would be absolutely necessary and thus increase. Bosses and overseers would be forced to recognize that there's only so much that can be done while the sun is out, and they wouldn't be able to demand as much from their employees and underlings. In so doing, work-related stress levels would go down dramatically.

In sum:

Energy bills=decreased.
Daytime productivity=increased.
Work-related stress=decreased.
Depression rates=decreased.
Time spent at home with family, friends and loved ones=increased.
Overall satisfaction with life=increased.

Now I ask you:
