December 17, 2015 saw the topping-out ceremony for the new Freiburg City Hall in Fehrenbachallee. The €78 million building is planned as an Energy Plus Building and is to be completed in less than one year. The Drees & Sommer engineering experts are supporting the city council with building systems engineering, building physics and facade technology, as well as consulting on energy design.
The new building is the first of three stages of a new administration center with a gross floor area of over 24,000 square meters. Some 840 Freiburg City Council employees – previously accommodated at various locations – will move into the building in November 2016. Designed by Ingenhoven Architects, the new City Hall is planned as an Energy Plus Building. Solar panels will be integrated into the facade and the roof to achieve this standard. This will allow the building to generate more energy each year than it consumes. The planned excess current will be fed into the city grid. The building will be heated and cooled by groundwater in conjunction with a heat pump.
The Drees & Sommer engineering experts are supporting Freiburg City Council with this project. As part of general technical planning, the experts’ responsibilities include building systems engineering, facade planning,
