The lighting in the Bundestag will be reduced with immediate effect to save energy.
As the parliamentary administration announced on Wednesday in Berlin, the dome lighting in the Reichstag building should be switched off from midnight every day after the end of visiting hours.
The dome's "artistic illumination lighting" will be completely turned off, as will the lights on the north and south facades, where there is adequate street lighting.
The lighting in the corridors, entrance areas and stairwells in the Reichstag building and the plenary hall is to be reduced.
However, corridors and corridors without daylight, as well as basements and tunnels, must remain illuminated around the clock for safety and fire protection reasons.
According to the information, the shutdown measures should begin on Wednesday evening.
In Berlin, other public buildings and landmarks should no longer be illuminated for the time being.
“In light of the war against Ukraine and Russia's energy policy threats, it is important that we use our energy as carefully as possible.
This also and especially applies to the public sector," said Senator for the Environment Bettina Jarasch (Greens) on Wednesday, according to the announcement.
Munich only wants to heat up to 19 degrees
The Victory Column, the Berlin Cathedral, the Memorial Church, the Red Town Hall and Charlottenburg Palace are among the 200 buildings that are the responsibility of this senate administration and are then no longer illuminated at night.
However, the lighting should not happen immediately everywhere, but gradually.
Three to four weeks are planned for this.
In the Munich city administration there will soon be no hot water due to the feared lack of energy.
Mayor Dieter Reiter (SPD) ordered this on Wednesday as part of a municipal energy-saving package.
"In order for us to get through the winter well, we have to significantly reduce the consumption of electricity and heating," explained Reiter.
"We are all called upon to make our contribution."
The city of Munich also announced that it would only heat up to a maximum of 19 degrees during the heating period, and that corridors and little-used rooms would no longer be heated at all.
The nocturnal lighting of historic buildings such as the town hall on Marienplatz is to be switched off.
The hot water is also turned off in the schools, as long as this does not affect children and young people.
Most fountains are also switched off at night.
In order to save energy, Baden-Württemberg is considering no longer illuminating state-owned buildings and castles with light at night.
A spokeswoman for the Ministry of Finance said on Wednesday in Stuttgart.
But that is not possible everywhere.
This is not the case with buildings in which, for example, a restaurant is operated or where security issues are concerned.
The spokeswoman was initially unable to say when a decision on the question should be made.
