Fresh Air and Saving Energy – How is This Best Done?
Stale air out, fresh air in: Ventilating often throughout the day ensures a better indoor climate and doesn’t mean wasting heat. To do this, open windows completely for about 5 minutes.
This ensures a quick and effective exchange of air. This process is called »shock ventilation« (»Stoßlüftung« in German). Even faster than this is »cross-ventilation« (»Querlüftung«), where windows are opened on opposite sides of a room. Set heaters to frost protection (asterisk) the whole time you are ventilating. Once the windows have been closed again, set the heaters back to between 2.5 and 2.9. This will quickly restore the room temperature back to normal. Please note: Corridors and stairwells are no longer being heated, so keep any doors to hallways closed when possible.
Additional energy-saving measures can be found at Saving Energy at the Bauhaus-Universität Weimar.
Background:
The Bauhaus-Universität Weimar is facing an unpredictable situation this year due to reduced gas delivery and limited supply. The State of Thuringia has asked the university to reduce our energy consumption by 15 to 20 percent. But how is this going to be possible? You can do your part by acting responsibly and frugally when it comes to energy consumption. You, too, can help use energy responsibly and efficiently.
