#FAUsavesenergy – saving energy at FAU to keep our FAU open

The topic of energy and energy costs will inevitably affect FAU in the coming months. First of all, however, we would like to reassure everyone, and our students in particular, that FAU will do everything it can to ensure that the University continues to operate over the winter without any major restrictions, especially when it comes to teaching face to face.

As it is not yet clear how the situation concerning energy supplies will develop in fall 2022, FAU is following a carefully thought out step-by-step plan. We are counting on you all to help us put this plan into practice. If we all work together, act sensibly and find innovative ways to save energy we hope we can save so much energy that we will not experience any bottlenecks in supply.

Our motto for the winter semester is #FAUspartenergie (FAU is saving energy). Let’s all take this to heart and do everything we can to make it a reality. At the same time, this will help us reduce our greenhouse gas emissions and work towards reaching net zero quicker than originally planned (see BayKlimaG). Use the hashtag #FAUspartenergie to share the ways you are saving energy on social media with us and the world and generate more awareness of this important topic.

This page will give you valuable tips for saving energy at FAU and at home, keep you up to date with current developments and give you the opportunity to bring any potential energy saving measures to our attention. We will also report back on ongoing results, savings and progress at FAU. Please bear with us if not all pages are completed yet, it is a work in progress.

What we can all do on a daily basis



  • Turn the heating down (overnight) and switch it off when it is not needed (for example at the weekend)
  • Reduce room temperature as far as possible; you can adjust to a lower room temperature by, for example, wearing warmer clothes
  • Close doors, air rooms by opening windows wide for a short period of time instead of leaving the window tilted all the time
  • Cut down on using warm water at the sink, if you have one

Electricity consumption

Electricity consumption

  • Stop using fan heaters, fans and other ineffective sources of heat/electricity
  • Switch off or replace old appliances such as fridges
  • Switch off PCs, monitors, printers and other devices instead of leaving them on standby
  • Reduce screen brightness to between 50 and 75% (saves over 25% energy), switch off second monitors
  • Avoid using lifts unless necessary for transporting items
  • Check whether fax machines are still necessary (they use electricity when kept in standby mode)
  • Use socket strips with toggle switches

in the office

in the office

  • Evening checks (lights off? Windows shut? Appliances turned off?)
  • Agree on fixed office hours for your team in consultation with your manager and adjust heating and lighting accordingly
  • Communicate possibilities for action, mention and raise awareness for energy saving measures among colleagues, pass on your knowledge and establish energy teams
  • Share electrical devices such as coffee machines and kettles in break rooms or kitchens and fill thermos flasks with coffee or hot water and have joint coffee breaks. Kettles should be descaled after a maximum of three months.

in research

in research

  • Reduce the number of devices left on standby when not in use
  • Switch off devices such as centrifuges, heating cabinets and water baths in the evening or directly after use (except for those marked otherwise)
  • Use socket strips with toggle switches
  • Share use of laboratories/devices
  • Introduce a booking schedule
  • Bundle production jobs (warm-up periods)
  • Only switch on those lights in the laboratory that you really need
  • Only open fridges/freezers/cooling chambers briefly and avoid keeping the door open for long
  • Check the temperature of the cooling chamber
  • Run freezers at -70°C rather than -80°C (28% saving), do not run them at their limit
  • Replace old, inefficient appliances and devices including appliances such as fridges (funding available for replacing old appliances from municipal authorities)
  • Ensure sufficient air can circulate around devices that emit a lot of waste heat, such as fridges or freezers. Remove servers from the broom cupboard.

  • Switch off lights in lecture halls after 8 pm and lock the doors

FAU on the road towards net zero


Lecture series: Ask the experts – Solutions for the future of energy

With rising energy prices and a shortage of gas, companies and private households are forced to save even more energy to lower their costs or prevent outages. What is the latest advice? Researchers at EnCN give advice based on practical examples from their work.

The lecture series is held online via Zoom between 5 pm and 6 pm on Wednesdays.
