Energy crisis

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".

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.

Please refer to the section below for more energy saving tips.

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.

The use of some lecture halls that are particularly unfavorable in terms of energy is restricted.
