Saving Energy while using air
Shut windows and external doors when operating
the air conditioner.
Minimise the area being cooled or heated by
shutting doors to unused rooms.
Follow the manufacturer's instructions for
The temperature of a heated room in winter
should be between 18-21°C.
The temperature of a cooled room in summer
should be about 23-26°C.
Each 1°C increase/decrease of the thermostat
setting could save in the vicinity 10% on your energy usage.
Reduce the amount of heat entering the
building by shading windows and walls, insulating ceilings and
walls and sealing draughts.
Open up windows and external doors if the
outside temperature is lower than the inside temperature, instead
of using the air conditioner.
Install the air conditioner (or outdoor unit of a split system) on
the shady side of the building (or shade the air conditioner
itself); make sure the air flow around is not restricted.
When a hot day is expected, turn on the air conditioner early
rather than wait till the building becomes hot (it operates more
efficiently when the outside air temperature is cooler).
If the air conditioner has adjustable louvre's, adjust them towards
the ceiling when cooling, and towards the floor when heating (as
cool air falls, hot air rises).
