Sustainability

Within the Institution

On an institutional level our work includes optimising the energy use of our buildings, instruction and advanced training for our staff and measures to compensate for and balance out unavoidable impacts.

Renovation of the Haus der Berliner Festspiele

Between the summer of 2018 and March 2022, the festival theatre has been renovated in keeping with the Federal Ministry of the Interior and Community’s guidelines on “Sustainable Building”. In addition to the energy-based refurbishment of the building’s outer shell, the roofs, façades and office areas, the works also include the installation of ventilation systems with heat recovery for the wings, backstage and rehearsal spaces, replacement of the cooling unit, installation of a rainwater capture system that allows rainwater diverted from roofs to drain away close by, replacement of large sections of the electrical system and conversion of the lighting stock to LED technology, installation of a new fire alarm system, partial renovation of the network of heating pipes and the replacement of some radiator units.

Energy Management at the Gropius Bau

At the end of 2010 a photovoltaic unit was installed on the roof of the Gropius Bau. Since then, it has generated 547,743 kWh of energy, all of which has been fed into Berlin’s electricity grid. The window surfaces at the Gropius Bau together with the large glass roofs above the central atrium and the vestibule have been fitted with double layers of insulating glass. Aluminium slats in between these and coating with sun protection film reduce the admission of direct sunlight and improve energy efficiency. The Gropius Bau is connected to the district heating and cooling networks. All its central ventilation systems are equipped with heat recovery features. Since 2016, a new cold-water pump for the air conditioning in the exhibition spaces on the ground and first floors has enabled the system to be adjusted automatically and operated on the basis of need. Since 2011, lighting in the exhibition spaces, staircases, cloakroom, toilets and administrative offices has gradually been replaced with LED units.

Renaturing of marshland

Marshlands are huge carbon sinks. While they only cover three per cent of the earth, their peat layers tie in a third of terrestrial carbon – twice as much as all the earth’s forests, which make up around 30 per cent of the land surface. Since 2020 the Berliner Festspiele have compensated for air travel by their staff and the release of CO2 this has generated by renaturing marshland through the purchase of voluntary climate protection certificates, MoorFutures.

Other Activities and Offers

A person rides past the Gropius Bau on a bicycle.

Rail and Cycle Travel

Business travel within Germany and well-connected European cities should be conducted by train and business travel within Berlin should be conducted by public transport. The regular provision of bicycle checks, repairs and instruction are intended to raise enthusiasm for cycling among KBB staff and increase their safety. Bicycle storage is provided.

In the garden of the Haus der Berliner Festspiele there are long white tables with white beer benches and white parasols.

Training and Guidelines

The KBB provides additional training for a sustainable events organisation and has put together relevant guidelines. Staff are trained to pay particular consideration to ecological factors when commissioning deliveries and services and to explore hosting artists and guests in an ecologically sustainable manner.

Service

Staff are able to dispose of their used mobile phones in special containers located inside KBB buildings. The telephones and rechargers collected in this way are donated to the NABU project “Alte Handys für die Havel” (Old Phones for the Havel) where NABU receives up to three Euro from the E-Plus group for each old phone it hands over. This money is then donated to the Lower Havel Conservation Project.
