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.
- 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.
- 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.
- 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.
