Energy crisis
Due to the current energy crisis and the associated enormous cost increases, especially for gas and electricity, as well as against the background of a possible energy shortage and the already strained budget situation, we have to take short-term measures to save energy at the TU Clausthal.
In the case of electricity, we anticipate a doubling and in the case of heat, a tripling of the costs that the university will have to bear from its own budget.
The following measures are effective immediately at TU Clausthal:
-
Offices
- Offices may only be heated to a maximum of 19 degrees.
- At the end of the working day, the temperature should be reduced to 16 degrees.
- During longer absences (e.g. home office, vacation) the room temperature should be set to 14-15 degrees .
- The Information sheet radiator thermostats gives you further information on the correct setting on the thermostats.
Meeting rooms
- Service meetings should be switched to video conferencing solutions where possible.
- Meeting rooms that are unused for a longer period of time can thus be regulated down to 14-15 degrees.
Corridors, stairwells, foyers, technical and storage rooms
- Set temperature to 14 degrees.
Proper ventilation
- If the room is used for a longer period of time, it must still be ventilated regularly to prevent the formation of mold.
- In winter, about 5 minutes with the window wide open is sufficient.
- Before airing the room: Turn off the heating!
- After the airing: Turn on the heating again!
Please inform yourself also in the lower area about "further energy saving tips".
-
Merging
- Offices are to be merged where possible in consultation with the supervisor. The home office arrangement also makes it possible to share a desk on alternate days. Thus, some rooms could be "shut down" and the temperature regulated down to 14-15 degrees for a longer period of time.
Duty meetings
- Preferably hold meetings online and regulate unused meeting rooms down to 14-15 degrees.
Adapt room size to the number of participants
- Where face-to-face meetings are absolutely necessary, adjust the room size to the number of participants. Always choose the smallest possible room (taking into account the corona situation).
Aula
- An extended winter break is scheduled for the auditorium from 12/17/22 - 01/25/23. No events can be held in the auditorium during this time.
-
Hot water must be turned off wherever it is intended only for washing hands (e.g. offices, sanitary areas), that is:
- Decentralized instantaneous water heaters / hot water boilers: are completely disconnected from the power supply (pull the plug!).
- Central boilers: are regulated down or taken out of operation, as far as a health risk due to legionella can be excluded.
-
Prohibition
- The operation of electric fan heaters, electric blankets, etc. is prohibited!
Exterior lighting of buildings
- The exterior lighting of buildings must be switched off unless it is intended for security or emergency lighting.
- The building lighting of the main building of Adolph-Roemer-Str. has already been switched off.
Lighting in general
- Review the timing of corridor lighting (if any) and optimize if necessary.
- Turn off central LED info boards if possible and replace with other info.
- Turn off lights when leaving the room.
- Turn off lights as soon as sufficient daylight is available.
PC pools
- Computers in the PC pools, which are centrally managed by the RZ, are shut down centrally at night.

-
Recirculating air cooling / room temperature
- In rooms with recirculating air cooling: Adjust temperatures in summer, e.g. 23-24 °C
- Run cooling water only if necessary - pay attention to circulation
- Close or switch off sashes or digesters / fume hoods in laboratories.
Energy-intensive devices
(e.g. cooling and heating units, vacuum systems, ultra-low temperature coolers, ventilation units and systems, drying cabinets, ovens, etc.)
- only switch on when absolutely necessary
- Defrost freezers regularly, if possible only operate at -18°C
- operate ultra freezers at -70°C if possible
- check optimal installation (removal of waste heat)
- pay attention to economical devices when purchasing
Compressed air
- The factory setting of 10 bar is generally not required. It is planned to regulate the compressed air down to 7 bar. Further information will follow from Department 4.
-
- Pay attention to the correct thermostat setting: Lowering the temperature just one degree can save 6% in heating energy. To heat the rooms to 19 degrees, set the thermostat one dash to the left of level 3. It will not warm up faster if you set a higher level!
- The information sheet Radiator Thermostatsgives you more detailed information on the correct setting on the thermostats.
- Keepdoors closed between rooms with different temperatures
- Arrange for heater check: if there are gurgling noises from the heater or if the radiator is not getting warm evenly: Place work order on Dec. 4
- Keep radiators clear: Radiators must not be obstructed by paneling / furniture / curtains. Ensure sufficient air circulation between furniture and critical (cold!) walls by leaving a gap of at least 5-10cm.
-
Shock ventilation
- Ventilate 3 to 4 times a day.
- To do this, first turn off the heating thermostats and open the window completely.
- Even more effective is cross-ventilation, in which opposite windows/doors are also opened to create a draught.
- Then close the windows and turn the heating back on.
- In winter, 5-10 minutes are sufficient (max. 5 minutes in sub-zero temperatures).
-
PCs, monitors, printers
- Use standbymode instead of screen sa ver: Screen savers on the PC prevent the standby mode. Therefore use the screen saver only for a short time (e.g. switch on after 3 minutes) and then use the standby mode on the PC (recommendation: switch on the standby mode after 10 minutes).
- Switch off office devices after work or longer periods of non-use / shut down computers, because even in standby mode the devices consume energy!
- Devices with lead times such as calculators and copiers or devices that are needed permanently should be operated in energy-saving mode.
- Operate and procure only those devices that are really needed.
Refrigerators / cooling devices
- Turn off unused or barely used refrigerators. Perhaps you could do without the refrigerator altogether in the winter?
- Consolidate refrigerators so that multiple offices use one refrigerator. Put unused refrigerators on display.
- Ideally place in a cool room, not exposed to direct sunlight.
- Do not place next to radiators or other heat sources.
- Ensure unobstructed air circulation.
- Clean the back of the cooling units regularly (have them cleaned).
- Procure energy-saving appliances.
Lighting
- Switch off lights when leaving the room.
- Switch off lights as soon as there is sufficient daylight.
- Check at closing time that lights are turned off everywhere.
Electronic devices in general
- Operate and procure only those devices that are really needed.
- Devices with lead times such as computers, copiers or devices that are needed permanently should be operated in energy-saving mode.
