- When you have finished using them, turn off the remote control devices (projector, screen, video player, DVD player, etc.) completely. The standby lights that stay on or flash day and night consume a lot of power. This “passive consumption” unnecessarily increases your electricity bill.
- Once the devices are charged, unplug the chargers. A charger (GSM for example) or a transformer (for example printer) continues to consume, even if you do not use the device.
- Place a switch between the plug and the dimmer or unplug it. Many dimmers continue to consume energy even when the lamp is off.
- During holidays, disconnect all devices. Empty the fridge (s) and turn off the fridge (s).
- Fill the fridges and limit their number. A shared multi-storey fridge consumes less than a half-full fridge on each floor.
- Remove the lighting from the drinks dispenser. It is lit day and night, even when it does not dispense drinks.
- Do not use the coffee maker to keep coffee warm. Pour the coffee into a thermos.
- Limit the number of electric water heaters if your employees consume little hot water. A natural gas geyser is more economical than a boiler. It heats the water only when you open the hot water faucet.
- Do not put photos as screen savers on your computer. A photo consumes as much energy as when you use the screen normally. It is best to put the computer into sleep mode.
- On weekends, switch off the drinks vending machines with a timer. The drinks will not be unnecessarily refreshed during the weekend.
- Equip the electric kitchen water heater with a timer. It will then turn off automatically outside office hours or cleaning.
- Place power strips with a switch in easily accessible locations. You will be able to quickly turn off unused devices.
Practical tips for heating
- Reduce the temperature by one degree: 20 ° C instead of 21 ° C. Lowering the thermostat by one degree saves 7% of fuel. However, do not increase the temperature difference between 20 ° C and 16 ° C: the building will cool down too much and it will take more energy to warm it up.
- If your business has few employees, group several in one room. You will save some heating days.
- Switch the thermostat to night mode one hour before employees leave the office. Comfort will be equal and you will save energy without realizing it.
- Avoid clogging the radiators. Do not put objects on them, do not cover them, and do not place a desk or wardrobe in front of them. The heat can circulate freely.
- Close the doors between the different rooms. A simple gesture, but effective.
- In the evening, close the curtains and / or lower the blinds, screens or shutters. The heat will stay inside.
- Air the rooms every day for a quarter of an hour by opening the window.Be sure to turn off the heat. You will consume less energy than if you leave the windows open permanently in oscillating position.
- Designate an energy manager. This person must ensure every night that all doors and windows are closed.
- Communicate clearly about energy consumption. Display a user manual (eg heating or air conditioning), a notice (eg thermostat programming hours) or an overview (eg consumption statistics).
- Isolate pipes in unheated rooms. Affix the insulation properly and tightly.
- Place a reflective screen or aluminum foil behind the radiators that are against an outside wall. The heat is then reflected and not absorbed by the wall.
- Regularly drain the radiators. Purge them preferably at the beginning of the cold season. If the radiators contain air, they do not heat up to 100%. Bleeding the radiators increases their efficiency.
- Decrease the temperature in poorly used rooms. You will save a lot of money! Be sure to keep the building free from frost (± 6 ° C).
- Place anti-draft seals. Seal the gaps and slots under the doors or at the flap box level with anti-draft seals. There are many models, very easy to affix.
- Avoid using an electric auxiliary heater. These devices consume a lot and come back very expensive!
- Install effective sun protection to reduce the consumption of conditioned air. In rooms with sun protection, the indoor temperature is often 4 to 6 ° C lower than rooms that do not have them.
- In summer, avoid using portable air conditioners. A small 1,400 W air conditioner can quickly boost annual consumption by 700 kWh.
- Do you plan to replace your boiler? Opt for a condensing boiler with natural gas. This type of boiler is much less energy consuming. In addition, you recover your investment in a relatively short time.
Practical tips for lighting
- Light only if necessary. Turn off the light as soon as you leave a room. The most economical bulb is one that is not lit!
- Never paint fluorescent tubes or frames. The luminous intensity of a painted light bulb decreases considerably. You will find colored bulbs in specialized stores.
- Make the most of daylight. Sunlight is free.
- Do not stick posters on the windows of a room. This prevents natural light from entering, which forces you to artificially light up, and therefore consume more.
- Use as much as possible economical, fluorescent and LED bulbs. Opt for the lowest wattage and longest life.
- Choose Energy Label A bulbs. For example, replace your old 40-watt (400 lumens) incandescent bulbs with 6-watt (400 lumens) LED bulbs.
- Replace old halogen bulbs with LED bulbs. Halogen bulbs consume more because much of their energy is lost in the form of heat.
- Install a detector or timer. The light does not remain unnecessarily lit (corridors, toilets, cellar, etc.).
- Paint the walls and ceilings in light colors. The light colors reflect between 60 and 90% of the light. If you opt for darker colors, you will need to turn on faster.
