So 500 people leave for office and turn off the heating at their homes, even if there are other people (kids, elderly) or animals (cats, dogs, birds) living there?
Kids are at school during office hours, I'm not sure about pets but they I don't think they care whether the house is 23° or 16° considering most of them go outside without any issue.
