The World War II bunker in Hamburg-Wilhelmsburg has been transformed as part of the IBA Hamburg (International Building Exhibition) project into the „Energiebunker“ which supplies the Hamburg Weltquartier and more neighbouring buildings with heat and power from renewable sources since late 2013.
Central elements of the energy bunker are our compact CHP units GG 530 and GG 237, solar heat and power collectors as well as a 2000 m² heat storage inside the buker. With the intelligent combination of renewable energies and a large buffer storage, the energy bunker can save up to 6600 tons of CO2. The plant engineered by Averdung engineering and operated by the municipial utilites supplier HAMBURG ENERGIE has been awarded with the first Deutscher TGA award (German building technology award) during Berliner Energietage 2014.
More information about the energy bunker in English can be found at the IBA website. The (German) article more focused on the CHP project in energy bunker published in September 2014 in ‚Euro Heat and Power‘ magazine can be downloaded here. Since the second CHP unit (GG 237) was installed in early 2016, the article only deals with the compact CHP unit GG 530.
