Sustainability & Conservation Tips


  • Keep your thermostat set at 24°C, or higher. Each degree increase in set point temperature can save up to 5% on AC consumption.
  • The optimal lifetime of an AC is ten years. If yours are older, consider replacing them with new energy-efficient ACs with 4 or 5 stars from Emirates Authority for Standardization and Metrology (ESMA). This will help you save up to 25% of cooling consumption.
  • 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 or dirty AC filters can block the normal airflow and reduce the system's efficiency significantly. It is recommended to clean your AC filters periodically or at least once a month during summer.
  • During the winter season, utilise the pleasant weather and low temperature to cool & ventilate your home instead of ACs to conserve electrical energy.
  • During the summer season, use curtains, drapes, shades, awnings and reflective materials to reduce the heat entering through your glass or windows.
  • Apply weather stripping and caulking around all doors and windows to keep the cooled air inside your house and to prevent hot air from entering into your home.
  • Use a programmable thermostat (Smart Thermostat) to better control the room temperature and AC operation duration. This will in turn reduce AC consumption.


  • Turn off lights in unoccupied areas to save energy.
  • Use efficient lights (LED) for indoor & outdoor lighting because of their longer lifespan and higher-efficiency compared to equivalent conventional lights.
  • Clean your light bulbs regularly, as dirt limits diffusion of light and decreases illumination.
  • Turn off unnecessary lights and use natural lighting as much as you can in places which are not exposed directly to sunlight during summer.
  • Use timers or motion-detectors to control the light's operation, wherever applicable.
  • Install dimmers to control the brightness of lights and reduce energy consumption.

Major Electrical Appliances Usage


  • A microwave consumes less energy than an oven.
  • Use flat-bottom pans for best contact with the heat, with tight-fitting lids to keep the steam in the container.
  • Pressure cookers use lesser energy than ordinary pots and pans.

            Water Heaters and Water Coolers

  • Switch off electrical water heaters during summer and water coolers during winter, this can save up to 50% on your water heating and cooling energy consumption.
  • When purchasing a new water heater, it is advisable to purchase solar water heaters if possible, or electrical water heater with top rating (5 or 4 Stars) as approved by ESMA.


  • Set the fridge temperature to 4°C or 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 your 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 energy efficiency rating (5 or 4 stars) as approved by ESMA to save energy.

Major Water Appliances Usage


  • Only run your dishwasher when it is full to make the best use of water, energy and detergent.
  • When purchasing a new dish washer, 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).
  • 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.


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 (19 litres) per day.
  • Clean vegetables in a bowl partially filled with water rather than running water from the tap, taking into consideration all health issues. Reuse the water for plants at your home.


  • 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.


            General Watering

  • Water your plants before 8 am or after 6 pm to reduce evaporation 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 condition.
  • 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 water 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, this indicates a water leak in the pipes or system.
