Heating, Ventilation and Air Conditioning (HVAC)
natural gas pilots
Turn off a standing natural gas pilot in your
space heating system every spring when
the heating season ends.
Natural gas pilots use as much as $5 to $10 worth of
natural gas per month. This measure saves money if
there is someone in your company who is able to turn
the pilot lights off and re-light them again. However,
if you have to call a tradesperson to re-light the pilots
then it may not be worthwhile, depending on how
many furnaces or boilers you have.
Thermostats
Install a programmable thermostat to
automatically control temperature settings.
Significant savings in operating costs may be
realized by raising the building temperature setting
during cooling season and lowering the building
temperature setting during heating season.
The amount of setback depends on the outside
temperature and how long it takes to bring the
area back to normal temperature. Generally set the
temperature for at least 26°C (78° F) in summer and
16°C (60° F) in winter during unoccupied periods.
Ventilation
Install controls on kitchen exhaust and make-up
air systems that automatically reduce fan speeds
during idle cooking.
Variable speed, demand-based exhaust, and makeup
air controls monitor your cooking to match your
ventilation needs, reducing excess energy use.
Turn off washroom, kitchen/coffee room and
general exhaust and supply fans when a room is
unoccupied or at the end of the day.
De-stratification or ceiling fans should:
• run all the time at a speed appropriate to the
space in winter;
• be operated to provide cooling only when the
room is being occupied in summer.
