Room Air Conditioners
  • Choose energy efficient air conditioners. Air conditioners with "Grade 1" energy label are most energy efficient.
  • Adopting inverter type air conditioners can save up to 40% annual electricity consumption compared with non-inverter type air conditioners.
  • Set and maintain air-conditioned room temperature between 24℃ and 26℃ in summer.
  • Use electric fans with timer control function instead of air conditioners where possible.
  • Consider using a fan in conjunction with an air conditioner to spread the cooled air more effectively.
  • Clean dust filters of air conditioners regularly and remove obstructions at air vents (i.e. air inlets and outlets) of air conditioners.
  • Keep windows and doors closed when air conditioners are turned on and use curtains or blinds to shade against sunlight.
  • Turn off air conditioners that are not in use.
  • Switch off lighting and heat-producing appliances that are not in use to reduce air-conditioning load.
  • Avoid direct sunshine on the outdoor heat exchanger units.
Refrigerating Appliances
  • Choose energy efficient refrigerating appliances. Refrigerating appliances with "Grade 1" energy label are most energy efficient.
  • Place refrigerators away from direct sunlight, cookers or other heat sources.
  • Leave enough space between refrigerating appliances and the walls or cabinets so that air can circulate around the condenser coils. Trapped heat increases energy consumption.
  • Make sure that the refrigerator door is closed and the door seals are intact. Avoid opening the refrigerator door too frequently.
  • Do not set the refrigerating appliance temperature unnecessarily low.
  • Allow hot food to cool down to room temperature before putting it into the refrigerator.
  • Do not store too much food in the refrigerating appliance. Cover all food stored, and arrange them properly so that cold air can circulate freely.
  • Defrost the freezer compartment of the refrigerating appliance regularly. Don't let frost build up in the freezer compartment as this will increase energy consumption.
  • Empty the refrigerating appliance and switch it off from the power source if going away for a long vacation.
Compact Fluorescent Lamps(CFLs)
  • Choose energy efficient CFLs. CFLs with "Grade 1" energy label are most energy efficient.
  • Turn off the lights when not in use.
  • Maximise daylight usage. Better choose a light coloured, high-reflectivity decoration scheme to enhance indoor light intensity.
  • Replace incandescent lamps with more efficient lamps (e.g. light emitting diode (LED) lamps or CFLs).
  • Use task lamps to minimise general lighting.
  • Keep light bulbs and light fittings clean to maximise lighting efficiency.
Washing Machines
  • Choose energy efficient washing machines. Washing machines with "Grade 1" energy label are most energy efficient.
  • Choose a washing machine that meets your household's needs. If your normal laundry loads are small, choose a smaller model that uses less water and patronise a public laundromat for large items like comforters.
  • Fully load the machine before washing. Washing a half load of clothes consumes almost the same amount of energy as a full load.
  • Separate clothes according to fabrics, colours and dirtiness; and wash clothes according to washing instructions to save energy and water.
  • Use a low-temperature wash cycle as far as possible. It is not only more energy-efficient but also better for clothes. At the very least, save the hot water cycle for your whites, and wash dark and coloured clothes in cold water.
  • Choose energy efficient dehumidifiers. Dehumidifiers with "Grade 1" energy label are most energy efficient.
  • Choose dehumidifiers that have automatic dehumidifying mode to prevent energy wastage.
  • Place dehumidifiers in a well-ventilated area and away from corners. Do not obstruct the air outlets and returns for optimum performance.
  • The dehumidifiers should be kept away from direct sunlight or heated equipment.
  • Keep windows and doors closed when dehumidifiers are on.
  • Clean dehumidifiers (including its filter) frequently to make them run more efficiently.
  • Choose energy efficient televisions. Televisions with "Grade 1" energy label are most energy efficient.
  • Switch off televisions after use.
  • Switch or plug off televisions at socket outlets as remote control devices could only switch televisions to standby mode.
  • Use intelligent panels or adaptors to turn off televisions automatically to reduce standby power consumption.
  • Turn down the brightness of television screens as far as possible to reduce power consumption.
Storage Type Electric Water Heaters
  • Choose energy efficient storage type electric water heaters. Storage type electric water heaters with "Grade 1" energy label are most energy efficient.
  • Use instantaneous water heaters as far as practicable. Otherwise, use energy efficient storage type water heaters.
  • Switch the water heater off after use or install a timer to control the switch-off time.
  • In summer, set the temperature of the water heater to the lowest acceptable level.
  • Install the water heater as close as possible to the taps.
  • Taking showers instead of baths consumes 50% less of hot water and energy.
  • Use cold water where hot water is not absolutely necessary.
  • Using a low-flow shower head saves water and heating energy.
Induction Cookers
  • Choose energy efficient induction cookers. Induction cookers with "Grade 1" energy label are most energy efficient.
  • Use induction cookers as they are more energy-efficient than electric stoves.
  • Defrost frozen foods in the air before cooking.
  • Use cooking utensils that conduct heat well to save energy.
  • When cooking, cover cooking utensils with lids to reduce heat loss.
  • Switch induction cookers off after use.
