Energy from waste water supplies urban district

Using waste water with organic substrates to produce biogas makes it possible to meet a large part of the electricity and heat demand in urban districts. This is being implemented on the site of former army barracks in Hamburg. This is where the new Jenfelder Au urban neighbourhood is being created with around 770 residential units. The drainage and energy concept provides for separate drainage of the domestic sewage already within the buildings and the conversion of the black water into biogas. The aim is to supply CO2-neutral heating.

Since the ground-breaking ceremony in October 2013, the largest inner-city residential area in Europe to have ever combined sewage and energy on a larger scale is currently being built in Hamburg’s Wandsbek district. The new district is located on the site of two army barracks, which were abandoned in 1998. In 2006, an urban design competition was held to develop the area, whereby the Jenfeld Community Conference and interested citizens were able to contribute with their own proposals. Part of the old barracks buildings are listed as historic monuments and, together with the former parade ground, shall remain as an architectural ensemble. The “Jenfeld 23” land-use plan, which came into force in April 2011, provides the legal planning basis for implementing the urban development concept. The development area covers approximately 35 hectares on which about 770 residential units will be created. 630 will be provided in new-build schemes, thus providing affordable housing for approximately 2,000 residents, in addition there will be supporting commercial facilities. Urban two- to four-storey townhouses and apartment buildings will complement the residential offer in Hamburg-Jenfeld.

The urban concept envisages ensembles of different urban townhouse types that are combined and terraced in various ways. This is intended to create a varied townscape. A neighbourhood park with a newly created pond, which also acts as a retention basin for rainwater, will form the heart of the district and provide a high amenity value. The new buildings must meet the legal standards of the Hamburg Building Code (HBauO) and the Hamburg Climate Protection Ordinance (HambKliSchVO). Beyond this there are no provisions for the building insulation. If the plans are implemented consistently, the future energy efficiency standard of the buildings should roughly correspond to the KfW Efficiency House 70. In 2011, the first building plots were tendered to investors and joint housing ventures. The various plots have been developed since 2013 and the first residents will move into the new urban district from 2015.
