Energy management


Here are some simple steps to help you reduce your energy consumption and enjoy a healthy, clean and well-maintained home.



  • Unplug small appliances when not in use.
  • Turn off lights when leaving rooms.
  • Unplug larger appliances (television, computer, etc.) when you leave your home for a long period of time.
  • Fridge: Defrost your fridge regularly (once a month). Do not put in hot food. The permanent operation of the refrigerator motor is a symptom of malfunction.
  • One degree less for the room temperature of the house represents a saving on the heating bill of almost 7%! The comfort temperature is about 19°C during the day and 16°C at night.
  • In winter, do not turn off your convector completely during the day and turn it back on strongly in the evening, but simply lower the heating power by a few degrees during your absence.
  • Hidden standby = hidden consumption! The TV set / computer / hi-fi system can absorb up to 100 watts per hour, that is to say an annual electricity consumption of about 80 €.



Simple gestures: did you know?


  • A shower consumes 15 liters of water if you are economical, and more than 60 liters if you leave the water running all the time.
  • A bath consumes about 150 liters of water.
  • For small uses (washing hands, brushing teeth, ...) do not let the water run continuously. There are no small leaks!
  • Dripping faucet 1,5 liters / hour or 15 m³ / year
  • Slight leakage from the toilet flush or water heater (safety group) 3 liters / hour or 30 m³ / year
  • Flushes 30 liters / hour or 250 m³ / year



Without having flushed the toilet, put a piece of toilet paper where the toilet flushes. The paper must remain dry, otherwise there is a leak. Notify your manager!



  • If there is a dripping sound without apparent water = leakage
  • If there are traces of rust around the cumulus = risk of leakage


In both cases, notify the manager for a technical control.



  • Ventilate / air: an essential gesture for a healthy indoor climate. Ventilate at least once a day for 15 minutes by opening the windows (remember to turn off the heating in the room during this time). In winter, do not exceed 2×10 minutes of ventilation per day: this allows to renew the air without cooling the walls.
  • To guarantee a permanent ventilation of the whole dwelling is essential = Do not obstruct the VMC and the ventilations.
  • Do not smoke, especially indoors. If someone is smoking inside, ventilate intensively.
  • Avoid the use of perfumes and air fresheners. Open the windows, the outside air remains the best remedy against bad smells.
  • Avoid the use of insecticides in the home. These products contain VOCs and substances that are harmful to health. (Some plants act as insect repellents).
  • Use cleaning products correctly. Exceeding the recommended doses does not improve the quality of the cleaning... Follow the instructions for use.
  • Vacuum mattresses every time the season changes. Dust mites are microscopic animals.
  • Unclog without polluting: Chemical drain openers are particularly toxic and dangerous. In case of clogged pipes, suction cups, pumps or spiral cables are often used to solve the problem.
