Ways to save energy in your building

The building

The more heat-proof the building is, the less heat is lost through the exterior walls, roof, doors, and windows, and the less energy is consumed. A well-functioning ventilation system is also important to maintain a good indoor climate.

Heating system

You should modernize the building’s heating unit, insulate distribution pipelines that carry heating and domestic hot water, and install thermostats on radiators.


Consume heat energy for heating rooms economically, by using modern control devices. A third of annual heat consumption is used to make hot water, so use hot water sparingly as well.

Sustainable consumption

Temperature control

The best indoor climate and energy savings can be achieved by installing a thermostat on radiators and/or other heating elements. If possible, install a thermometer or temperature sensor in each room to get exact information about the room’s temperature.


If your building has a ventilation system, you should be ensured a good indoor climate. In the absence of ventilation, the premises should be ventilated regularly, but windows should not be left open for extended periods of time. Open the windows in several rooms at the same time and close them after 10 to 15 minutes.


Open any window coverings during the day to let in heat and light and close them at night to reduce the amount of heat escaping through the window glass. Ensure that curtains do not cover the radiators, as this prevents heat from reaching the room.
