Award-winning architecture

As part of the IBA Heidelberg (2012-2022), the Collegium Academicum was built on the site of a former US military hospital in the Rohrbach district of Heidelberg. It plays a key role in the revitalisation of the long-dormant district. [...] As the first and largest self-managed and self-financed student housing project, the project, which is being supervised by DGJ Architektur, is unique in Germany.

[...] The Collegium Academicum is a model for a socially just and socially educational district that implements all the parameters of sustainable construction, reuse and climate-adapted architecture in an exemplary manner.

The integrative family centre by the association 'Deutscher Kinderschutzbund e. V.' in Dresden's Johannstadt district is a prime example of the successful transformation of a derelict industrial site into a lively place of social interaction. Under the planning of Alexander Poetzsch Architekturen BDA, the old factory site was reactivated and renovated and remodelled with the greatest possible respect for the existing building fabric.

[...] The innovative content of the project lies in the sensitive, minimal intervention in the existing building, which favours the reuse and further use of the existing building fabric. This not only saved material and energy that would have been required for demolition and new construction, but also reduced the investment costs compared to a comparable new building. In addition, no new surfaces were sealed, further minimising the ecological footprint of the project. The use of low-maintenance surfaces and built-in parts, as well as the avoidance of complex building services, also ensure the long-term stable and sustainable maintenance of the building.

Together with the client, elobau GmbH & Co. KG, f64 Architekten and Stadtplaner GmbH have planned and constructed the extension to Plant II for sensor technology, which is exemplary in terms of the quality of stay for users, today's requirements for emission- and resource-efficient production and operation and, last but not least, the architectural quality and integration into the regional context.

The new single-storey extension comprises two halls with production and office workstations that can be flexibly accommodated in the halls. The orientation of the shed roof building, optimised on the basis of energy and daylight simulations, allows for glare-free lighting, meaning that artificial lighting can be largely dispensed with. The PV system on the south-facing roof surfaces covers the building's own electricity requirements. Additional energy requirements are covered by a nearby biogas plant. Fossil fuels are not used. The building thus achieves an energy-plus standard and climate-positive operation.

As the central exhibition building of the Wangen im Allgäu State Garden Show, the hybrid flax pavilion demonstrates how robotic manufacturing can be used to create material-efficient load-bearing structures from bio-based, locally available materials. The Institute for Computer-based Design and Construction (ICD) and the Institute for Load-bearing Structures and Structural Design (ITKE) at the University of Stuttgart have used integrative, computer-based planning methods to develop and realise the world's first hybrid of cross-laminated timber panels and natural fibre bodies.

[...] The roof structure of the hybrid flax pavilion shows how fast-growing natural fibres in material-hybrid structures can significantly reduce the use of building materials, in this case the composite partner wood. The non-destructive construction, which can be separated by type, allows the individual components to be used as reuse components.

With the conversion of the Church 'Johanneskirche' in the Manfort district of Leverkusen into a day care centre, the Leverkusen church district of the Protestant Church in the Rhineland is making an architecturally and structurally relevant contribution to the conversion of deconsecrated listed churches. [...] zweipink Pink Architekten have revitalised this important church building in a resource-saving and flexible way by making clever use of the existing building and converting it into a children's day care centre.

This nomination successfully addresses the socially important and topical issue of the just transformation of church buildings. Church buildings must be used in a variety of ways in the future if they are to be preserved. This exemplary conversion to a children's day care centre places people and the social aspects of sustainability at the centre of the transformation. Another defining feature of the conversion is the option of reversibility, i.e. the reversible change of state of non-standard church installations and conversions.

With the "White City" daycare centre, Knoche Architekten, together with the city of Oranienburg as the client, succeeded in implementing a local pioneering project for ecological and economical construction in an exemplary manner.

By accommodating the building in a compact two-storey structure surrounded by an external pergola, a transferable typological answer was also found for this important building task. [...] In a triad, the "Weiße Stadt" day care centre positions itself as a contemporary, environmentally conscious new building for society in terms of construction, atmosphere and operation.

The Riedel Bau AG training hall has become a small solitaire in the typical grey world of industrial halls. Hidden away on the company premises, surrounded by grey industrial buildings, asphalt driveways and concrete storage areas, it really catches the eye as soon as it is seen.

[...] The fact that the concept originated from a youthful idea of the trainees of Riedel Bau AG and was then consistently designed and realised by the company's own trainees under the professional supervision of the ASAP Institute for Sustainable and Climate-Friendly Architecture gives the solitaire the icing on the cake. The jury is of the opinion that the small solitaire, with a floor area of just under 240 square metres, is an example of sustainably designed and built empty hall space for teaching and learning.

The new building of the Montessori Centre with the uses secondary school and kindergarten makes an architecturally and building-technologically relevant contribution to the current discourse on the planning and construction of school buildings. The three-storey Montessori Centre south of the railway tracks of Nuremberg East station with 2983 m² was planned by Diezinger Architekten GmbH.

[...] The objective of constructing a school building that combines flexibility in the room layout, a high quality of stay in the rooms, a diversity of indoor, intermediate and outdoor spaces with low maintenance and operating costs, as well as low CO₂ emissions, can be achieved with a good planning team in cooperation with an ambitious client using low-tech concepts and is demonstrated in an exemplary manner by the Montessori Centre.

The functional buildings of sports facilities are often characterised by great triviality and one-dimensional requirements. Even new facilities are rarely an exception. The sports and education campus designed by the architectural firm prosa for the town of Bürstadt is a different story.

Both the overall facility, the utilisation concept and the climate and environmentally friendly construction method are planned and implemented in an exemplary manner. This begins with the floor slab made of recycled concrete, continues with the glulam construction and extends to the multi-layered exterior wall structure with wooden shingle cladding and blown-in insulation made of recycled paper. The partition walls made of rammed earth have a positive effect on the indoor climate, minimise acoustic interference and act as a thermal storage mass. All materials can be separated by type. Maintenance-intensive building services have been largely dispensed with. Nevertheless, the entire campus is climate-neutral thanks to the connection to a local heating network and a groundwater heat pump powered by PV electricity.
