Grüntenstraße 30 – 36, Augsburg

Category: Facade renovation
Total construction time: October 2011 – March 2012

Modernisation of a multi-storey building with 60 residential units

Challenges

The modernisation work on the block of flats took place while the building was fully occupied, so the interests of the residents were a key concern in the planning phase.

Innovation

The plan that resulted from the architectural competition had won on the basis of its attractive facade design with generous sunrooms and painted wood panelling.

Solution

By ensuring a high degree of pre-fabrication of the elements used in the extension work and the building shell, the building's owner, WBG Wohnbaugesellschaft der Stadt Augsburg GmbH, optimised the construction time and kept the disturbance to a necessary minimum.

Transfer

The large-scale wood frame elements (TES EnergyFacade) were mounted as a facade on top of the existing load bearing structure within a short timeframe. The self-supporting elements transfer the vertical loads to strip foundations set in concrete that was already in place and are attached to the edge of the ceiling face of each storey by means of previously mounted wooden beams.

Sustainability

The efficient modernisation of the shell and technology have made the building so energy-efficient that it comes in 22% below the latest EnEV limits and meets the KfW Efficient House 70 Standard. The WBG's residential complex was modernised and funded under the Model Project "e%-Energieeffizienter Wohnungsbau" run by Bavaria's Board of Building and Public Works. The aim of the Model Project is to help achieve a permanent reduction of CO2 emissions in the housing it sponsors and to field-test economical and efficient methods of energy management. The target is to get energy consumption up to 40% below the limits specified in EnEV 2009.

Result

The building shapes the cityscape on the eastern fringes of the town. The measures have helped to create apartments fit for the future and draw the tenants' lasting interest.
