After almost two years under construction, the new complex – consisting of office and laboratory buildings in Duisburg’s city center – was handed over to the user and buyer on November 30, 2018 by real estate developer Aurelis Real Estate.
Around 400 employees of the Regional Authority for Nature, the Environment and Consumer Protection (Landesamt für Natur, Umwelt und Verbraucherschutz, LANUV) are due to move into their new premises by the beginning of 2019. With around 16,500 square meters of rental space, the building complex at Duisburg’s central station offers plenty of room for office and research facilities. The ground floor of the office building has a staff restaurant and a conference and event area, while the laboratory building has 80 laboratories. A new parking garage on the neighboring site holds 603 parking spaces, of which 150 will be for the Authority.
Drees & Sommer supervised the project for Aurelis from its beginning in 2012. First, Drees & Sommer carried out a feasibility study which verified that LANUV’s floor space requirement could be met by the site of Aurelis. Once the 20-year lease agreement was signed, Drees & Sommer’s project management, commissioning management and general contractor controlling services ensured that the project was realized on schedule and within the budget. The experts from Drees & Sommer are also responsible for the achievement of Gold certification from the German Sustainable Building Council (Deutsche Gesellschaft für Nachhaltiges Bauen, DGNB) and the green build rating system Leadership in Energy and Environmental Design (LEED). Other project participants were the general planning team of agn Niederberghaus & Partner GmbH, and HOCHTIEF as general contractor. Also involved were more than 600 tradespeople from 85 trades, who laid around 300 kilometers of cable and installed 1,260 windows and 820 doors on the project over the past two years.
The energy standards achieved by this sustainable and carbon-neutral public building are almost on a par with passive house standards. On the roof of the building is a large photovoltaic system to reduce energy demands. Also, rainwater is harvested and used for toilet flushing. The project is a perfect example of how public construction projects can be completed on schedule, within the budget, and to the required standard of quality in collaboration with private investors.
