You may be able to turn off your HVAC system in certain
areas: storage spaces, or parts of the building that are only used during a portion
of the day.
You can do this if you have multiple zone controls, or separate
units like window air conditioners. If there's a regular pattern of use in your
building, you can install timers to control usage.
If you can't turn off parts of your heating or cooling system,
consider these actions:
Have a zoned system with separate controls installed.
Cut off parts of your central system and replace them
with window air conditioners and space heaters. This may also make your main
HVAC system more efficient by eliminating long duct runs that often lose energy.
Revise your space plan. Move activities that require
little energy to areas that are poorly served by your system.
