9.3.3 Energy efficiency
Energy efficient systems and appliances will help to reduce energy use and save on costs. The following considerations
are important:
A. Air conditioning system
• Make sure that the air-conditioning system is regularly cleaned and serviced.
It can help prevent costly heating and cooling bills.
• Optimise the indoor temperature.
B. Styling appliances
• Unplug styling appliances when not in use, as they still pull energy and generate
heat when plugged in.
• Use equipment with an energy efficient label.
C. For lighting system
• Use energy efficient lighting (LED, T5 fluorescent lighting or
.
• Consider circuitry to create flexibility in lighting intensity.
• Zone lighting to allow the ability to control switching off or dimming lights to suit
usage.
• Turn off lights in areas that are not in use.
• Dimming control of lighting.
D. For water usage
• Ensure water heaters are fitted with timers that switch off half an hour before the
salon closes.
• Turn down the hot water temperature where possible. For example, reduce hot
water temperature from 60°C to 48°C whenever appropriate and practical.
• Good insulation of water heater and hot water pipes to prevent heat loss.
• Lower hot water temperature.
• Use of heat recovery unit and heat pump.
E. Other aspects in hair salons
• Only use tumble dryer when there is a full load.
• Install occupancy sensor where people seldom go (e.g. toilets).
