Sustainability & Conservation Tips

Cooling

  • Keep your thermostat set at 24°C, or higher, and on "auto mode". Each degree increase in set point temperature can save up to 5% on AC consumption.
  • The optimal lifetime of an AC is 10 years - If yours are older, will consume more electricity. Consider replacing them with new energy efficient ACs with 4 or 5 stars from ESMA
  • Use fans to circulate air. They use about as much electricity as a light bulb and can make you feel comfortable at higher thermostat settings, and do not forget to turn fans off when you leave the room.
  • Clogged, dirty AC filters block normal airflow and reduce the system's efficiency significantly. You should clean your AC filters periodically or at least once every 3 months.
  • During winter time: Be aware of temperatures! If it is cooler inside than outside, keep the windows and drapes closed. If it's cooler outside, open the windows and drapes to ventilate and let the outside air cool the house.
  • Use curtains, drapes, shades, awnings and reflective materials (as applicable) to reduce the heat entering through glass / windows. These block out heat from sunlight that enters from windows, reducing the need for AC usage.
  • Windows and doors with gaps and openings leak cold air. This means that your air conditioner will have to work extra hard to cool the premises. Apply weather stripping and caulking around all doors and windows to keep the chilled air inside your house and to prevent hot air entering in the premises.
  • Use a programmable thermostat (Smart Thermostat) to better control the room temperature and AC operation duration. This will in turn reduce AC consumption.
  • Use air conditioners with top rating (5 Star) as approved by the Emirates Authority for Standardization and Metrology. A 5 Star AC can save you about 25% on cooling bill compared to 1 star AC.

Lighting

  • Turn off lights when not needed or in unoccupied areas to save energy.
  • Use Induction or LED lights for outdoor lighting because of their longer lifespan and higher-efficiency compared to equivalent conventional lights.
  • Use LED lights, because of their longer lifespan and higher-efficiency compared to equivalent conventional lighting type. LED lights are up to 80% more efficient than conventional lights.
  • Clean your light bulbs regularly, as dirt limits diffusion of light and decreases illumination.
  • Use timers or motion-detectors to control the light's operation, wherever applicable.
  • Each LED lamp can save you up to 1,000 AED compared to incandescent or halogen lights over its lifetime.
  • Install dimmers to control the brightness of lights in your premise and reduce the lighting consumption. Look for dimmers that are compatible with your lights.
  • Switch off the lights in areas where natural lighting is available. Increasing the amount of natural light that enters your home reduces the need for artificial lighting.

Major Electrical Appliances Usage

Cooking

  • Use your microwave oven instead of your main oven whenever possible.
  • When you have to use your oven, cook more than one item at a time.
  • Use flat-bottom pans for best contact with the heat, with tight-fitting lids to keep the steam in the pan.
  • Pressure cookers use much less energy than ordinary pots and pans.

Water Heaters and Chillers

  • Switch off the electrical water heater during summer and water cooler during winter, this can save you about 50% on your water heating and cooling energy consumption.
  • When purchasing a new water heater, it is advisable to purchase solar water heater if possible, or electric water heater with top rating (5 or 4 Stars) as approved by the Emirates Authority for Standardization and Metrology.

Refrigeration/Freezing

  • Set the fridge temperature to 4°C. Or set your refrigerator temperature to the manufacturer's recommendation to avoid excessive cooling and wasting energy.
  • Keep your freezer temperature at - 18 degree Celsius.
  • Check your refrigerator/freezer door gasket periodically for signs of deterioration.
  • Allow hot food to cool down before placing in refrigerator.
  • Keep your fridge away from the oven, dishwasher, dryer and direct sunlight to avoid overworking.
  • When purchasing a new fridge, consider purchasing one with a high ESMA energy efficiency rating (5 or 4 stars), to save energy.

Major Water Appliances Usage

Dishwashers

  • Only run your dishwasher when it is full to make the best use of water, energy and detergent.
  • When purchasing a new appliance, look for one offering several different cycles including Eco cycle. This will allow you to select more energy and water efficient cycles when heavy-duty cleaning is not required.
  • When purchasing a new dishwasher consider purchasing one with a high ESMA energy efficiency rating (5 or 4 stars).

Washing Machines

  • Wait till you have a full load of laundry before running the machine to save both water and energy. If you can't wait for a full load, use the right water level to match the size of the load.
  • When purchasing a new washing machine, consider purchasing one with a high ESMA energy efficiency rating (5 or 4 stars), to save energy.
  • Reducing the temperature at which your washing machine operates is an easy way to save electricity. You don't always need to wash your clothes on higher temperature settings.
  • Dryers consume a lot of electricity. Take advantage of the sunshine and hang your clothes to dry. Hanging your laundry out to dry, will also help you reduce your electricity consumption.

Facts

  • Washing machines can use up to 170 litres of water per cycle and dishwashers as much as 22 litres per cycle.
  • A full dishwasher is more water efficient than washing the same load by hand.

Showers and Faucets

  • Install a water-efficient showerhead with a flow rate of less than 8 litres per minute.
  • Install aerators on your kitchen and bathroom faucets to reduce faucet water use by up to 40%.
  • Turn off the water when brushing your teeth or shaving and save more than 5 gallons per day.
  • Clean vegetables in a pan partially filled with water rather than running water from the tap. (To be reviewed considering the health issues)
  • Reuse the water used to wash vegetables to water houseplants.

Toilet

  • New toilet models use up to 6 litres of water per flush, which saves about 6 litres per flush compared to the older models, resulting in an annual water saving of around 10,000 litres per person.
  • Check toilets periodically for leaks and repair them promptly.

Irrigation

General Watering

  • Water your plants before 8 am or after 6 pm and avoid watering on windy days to reduce evaporative losses.
  • Use Treated Sewage Effluent (TSE) from Dubai Municipality (if available) to irrigate green spaces when possible.

Sprinklers/Sprinkler Systems

  • Check sprinkler system valves periodically for leaks and keep the heads in good repair.
  • Adjust the timer on automatic sprinklers according to seasonal water demands and weather conditions.
  • Install a rain shutoff device on automatic sprinklers to eliminate unneeded applications.
  • Place your sprinkler so it only waters the lawn, not the pavement. Avoid sprinklers that spray a fine mist, which increases evaporation.

General Outdoor

  • Wash your car with a bucket of soapy water instead of using a hose or pipe.
  • Clean your outer courtyard with a broom instead of the hose.
  • Cover your swimming pool to reduce water losses due to evaporation.
  • Conduct a leak test two times a year by switching OFF all water devices and checking the water meter. If the meter is still running, there might be a leak in the water pipes or system.
