I'm not sure that they're actually after natural light. Windows, yes. Natural light, probably not. In order to be considered a bedroom, you need a way of exiting the room in the event of a fire. Windows do that. In areas with basements, the window needs to be an egress window so someone can actually crawl out. https://www.google.com/search?site=&tbm=isch&source=hp&biw=1920&bih=1017&q=egress+window https://www.google.com/search?site=&tbm=isch&source=hp&biw=1...
