Saving energy in schools: efficient measures for a sustainable future

Why energy conservation is so important in schools

Schools are not only places of learning, but also major energy consumers. An average school in Germany consumes approximately 100,000 kilowatt-hours of electricity and 1,000,000 kilowatt-hours of heat annually, which amounts to electricity costs of around 50,000 euros and heating costs of approximately 100,000 euros. Energy consumption is also very high in elementary schools.

These figures illustrate just how high energy demand is in educational institutions—and what financial burdens are associated with it. But with our tips and measures, which we’ll share with you in this blog post, you can significantly reduce energy consumption, save money in the long term, and increase energy efficiency in schools—for the benefit of the budget, the environment, and the climate.

What consumes the most energy at school?

The largest share of energy consumption in schools is accounted for by heating the buildings. Outdated heating systems, inadequate insulation and inefficiently insulated windows contribute significantly to high heat losses. In addition, the Power consumption for lighting, IT and other electrical devices play a significant role. The number 1 electricity consumer in schools is the Lighting.

How can you save energy in a school?
Our energy-saving tips:

 

  • Building insulation

    Effective thermal insulation of walls, roofs, and floors significantly reduces heat loss. Replacing old windows with modern, energy-efficient models also helps lower energy consumption. Such measures can significantly reduce heating energy requirements.

  • How to Adjust Radiators Properly

    By properly adjusting the thermostatic valves, you can optimally control the room temperature. Even a one-degree reduction in temperature can save up to six percent in heating energy. Wireless radiator thermostats are also useful here, as they allow you to set schedules based on work and vacation calendars, as well as lower the temperature at night. Discover our DEOS TEO wireless radiator thermostat!

  • Proper Heating and Ventilation

    Air-out the room instead of leaving windows slightly open to ensure a quick exchange of air without letting the rooms get cold. Turn down the heat while ventilating.

  • Turn off the lights and appliances

    Turning off the lights during breaks and after class, as well as unplugging electrical devices that are not in use, helps prevent unnecessary electricity consumption. Please also read our page on room automation, which covers energy-efficient lighting control.

  • Energy Management Systems

    Implementing energy management systems enables continuous monitoring and optimization of energy consumption. By analyzing consumption data, potential savings can be identified and targeted measures can be taken. Learn more about building energy management on our blog or about our practical and user-friendly energy monitoring software!

  • System Maintenance

    Regular maintenance of heating, ventilation, and air conditioning systems ensures that they operate efficiently. Outdated or defective components should be repaired or replaced promptly to minimize energy loss.
