Habitation

Heating

Energy savings for the heating of rooms prove particularly effective, since heating accounts for roughly 20% of the total energy requirements of homes.

Adequate sealing of doors in unheated rooms
This is of particular importance in older buildings with a basement and an attic. It prevents drafts of air, thus providing more comfort.

Good thermal insulation
Thermal insulation in basement and attic floors are cost-efficient practices. When the time comes for the façade to be repainted, it is a good time to think about installing external insulation.

New windows
They will allow considerably less heat to escape and also make for a whole new appearance.

Reduce involuntary ventilation losses
Leaky windows, punctured doors and gaps/cracks in the roof panel can easily make up for ¼ of the total heating demand, especially in older homes. On cold days, test whether you perceive cold air penetrating into your home. Otherwise, let an expert run the so-called "Blower test" for you.

Avoid unnecessary ventilation losses
Ventilate your home by opening your windows fully for a short period of time. 5 to 10 minutes, once or twice daily, repeat more frequently if needed. Do not leave windows permanently open, not even a tiny bit. In winter close your windows during the night, also in the bedroom. For enough fresh air it is sufficient to ventilate the bedroom for five minutes before going to bed and then leaving the room door a bit open. Additionally, nowadays there are automatic ventilation systems which let in a boost of fresh air from the outside from time to time.

Excessive room temperature, also by cold weather
With warmer clothing we can easily live comfortably at 20-21 ° C. Not only that, but it turns out to be healthier as well.

Comfortable ventilation with heat recovery
The installation of such a system brings a potential savings of 30% and on top good, dust-filtered air and noise insulation. Investment costs per home: approx. CHF 15 000.

Lower night heating temperature to 16-18 °C
Particularly recommended in houses, where heat insulation systems are insufficient.
Savings potential: considerable

Additional reductions
These are available if you are heating with gas, wood or a thermal pumps.

Hot water

Using hot water sparingly, without giving up on comfort. Heating up water accounts for approx. 8% of the total energy requirements.

Take showers instead of baths
Taking a shower instead of a bath saves an appreciable amount of energy and water.

Saver shower head
Taking a shower with a saver shower head reduces the energy and water consumption substantially.

Solar thermal system
It heats water by using solar radiation. The investment costs, including a new water storage, is approximately CHF 10,000.

Flow restrictor
It reduces the water flow in all plumbing fittings.

Washing your hands...
...possibly only with cold water.

Electricity

We all consume too much electric power and thus waste valuable energy. For the environment and for the climate, it is necessary to consume as little electricity as possible.

Domestic appliances
From now on, purchase only new appliances with energy-ratings of A or A++.

Electronic devices and lights
When not in use, electronic devices should be turned off. Avoid the stand-by mode!

Pressure cooker or steamer
It is possible to do your cooking with such devices. When cooking there should always be a lid covering the cooking pan.

Kettle
The water for making tea or coffee should be warmed up in a kettle/boiler and not in a pan.
