Save energy together

Information of the Presidential Board from 14.11.2022

Dear University Community,

In order to make our solidarity-based contribution to saving energy and at the same time come one step closer to our goal of climate neutrality, the UW/H has taken a number of central measures about which we would like to inform you at this point. We would also like to encourage you to participate in our energy saving campaign and to achieve savings yourself by making small changes in your everyday work. Let us take on this responsibility together to get through the winter well!

We would like to present you with three figures that impressively show what we have already been able to achieve through successfully implemented measures:

  • 80%: We have replaced all photocopiers in recent weeks. This alone reduces the power consumption per device by 80 %!
  • -70 °C: In the research laboratories at Stockumer Straße 10 and 12, the deep-freeze temperature was increased by 10 °C to -70 °C. This saves 60 % electricity. This saves 60 % electricity! At Stockumer Straße 10, the old boiler system was also replaced.
  • 1.5 months: The new photovoltaic system on the roof of the new building generates around 67,000 kilowatt hours per year under optimum conditions. This covers the electricity consumption of the UW/H for 1.5 months.


That's not all! You can find out which other key measures have already been implemented and what steps we will be taking in the coming weeks in the Intranet section. Here you will also find a comprehensive list of how you can get involved in our energy-saving campaign - both at your workplace and in your private household. Three examples:

  • Reduced room temperature and ventilation: In the centrally heated offices and seminar rooms, the temperature is set to 19 °C during the heating period; in the corridors and entrance hall in the main building, the temperature is set to about 10 °C. We ask employees who work in decentrally heated rooms to ensure that they maintain a temperature of 19 °C on their own. In addition, airing the rooms at regular intervals instead of tilting them saves energy.
  • Avoid stand-by losses: It is best to shut down your appliances completely after work. Other electrical appliances such as monitors, chargers or appliances in the kitchen should also only be connected to the power supply when they are in use.
  • Decentralized power consumers: we ask you not to use individual electrical appliances (such as kettles or coffee makers) in your offices, but to use the central appliances in the kitchen.


In the next few days, you will find our energy-saving tips and small reminders on posters in the university, on sustainably produced window stickers or on passage doors. The materials will be sent out promptly via in-house mail, and you can also get supplies at the Post Info. To get started, we also recommend this videoin which we take a look at the campaign.

If we implement the wide range of measures together, we can reduce energy consumption by about another 10%, according to studies. In terms of the entire University of Witten/Herdecke, that's several dozen tons ofCO2e. We would be delighted if you would join us!

Yours sincerely
