Turn off the lights if nobody’s there.
Home at last, it was a long day and it’s late. First you just turn a light on, and everything looks nice and cosy. Minutes later seven lights are on in four rooms. However, you’re only in one. Make it a habit to only have the lights on in the rooms where you currently are. Configure your home so that you can use as much natural light as possible. And wherever possible use only energy-saving bulbs from brand-name manufacturers – these use up to 75 percent less electricity than incandescent bulbs. Cheap energy-saving bulbs often don’t last that long. The best light colours are “extra warm white” or “warm white” – they are very close to the colour of incandescent bulbs. High-quality energy-saving bulbs are also a worthwhile option when the lights are frequently switched on and off,for example in stairwells. In cases like this, a time switch control is recommended. In seldom-used rooms, such as a basement or attic, and also in the garden, motion detectors make sense.
It doesn’t always have to be like a sauna.
In addition to the rent, heating is often the largest cost-of-living item – and it offers the highest potential for shrewed savings. Even if you lower the room temperature by one degree Celsius, you save 6 percent of the energy consumed. With a clever mix of measures you can achieve a great deal more. Ventilate intermittently (open the window for five to ten minutes) – if you leave the window open while running the heating, you’re heating the street. Install a heating thermostat – this way you can set the room temperature at night and during prolonged absences to 15 to 17 degrees. Make sure that windows and doors and your home’s walls and attic are well sealed. And be sure that your radiators are clean and not clogged up so that they provide optimal heat output.
