Re: [GBlist] question about turning heat down

[Jan Fillinger <janfillinger@jb.com>]

The answer, as you may have gathered from the somewhat insulting comments, 
is that you will save energy if you don't heat the rooms while nobody is in
the space.  Heating or lighting unoccupied spaces is wasteful.  There are
of course more complex issues associated with this question, such as how
long the space will be unoccupied.  Turning off the heat, air-conditioning, 
fluorescent lights, HID lights, or computers for only one hour of absence 
might not be economical for some of the equipment in the long run.  But for 
anything approaching two or more hours of off-time, the general consensus 
is that energy savings do will outweigh the wear and tear on the equipment.
