The Interior
To save energy on lighting, replace traditional bulbs with fluorescent
bulbs. Use lampshades with white liners because they provide better
reflection. And arrange lamps so that light reflects off two walls rather
than just one.
Regarding your HVAC system, keep filters, grills, and coils on furnaces
and air conditioning units clean to help them run efficiently and save
energy. Also, be sure the heating/air conditioning ducts are clean.
Do not block hot or cold registers with furniture. Close drapes and
blinds to keep the sun out of rooms. Also, glass doors surrounding a
fireplace reduce the radiant heat from the fire but they allow you to
enjoy the fire while saving heat your furnace is producing.
