- Raise your blinds and open your curtains to make the most of daylight.
- Don’t leave lights on in unoccupied rooms or areas.
- Turn off conventional fluorescent lights when you are outside the room they are in for more than 10 minutes.
- Use LED light bulbs: they are brighter than conventional bulbs but use a lower voltage.
- Make a rational use of your computer and electrical devices, don’t forget to switch them off when you are not using them and do not leave them on standby.
- Make sure you have good thermal insulation to keep the sunshine at bay during the summer (blinds, awning) and prevent the loss of heat in the winter (good insulation in walls and roofs, double glazing, curtains etc.).
- Adjust your thermostats to a suitable temperature (20ºC-21ºC in the winter and 25ºC-26ºC in the summer).
- Use category “A” electrical household appliances (the most efficient in water and electricity saving).
- Don’t use the oven or microwave for defrosting; take your food out of the freezer in good time and let it defrost inside the fridge.
