As an addition to the Call for Teams, published on 29th of March 19, the following information presents the three urban situations based on examples from Wuppertal’s built environment. It gives an overview of the three situations and provides key information. After participating Teams are selected, detailed information on the buildings, such as floor plans, views, sections etc., will be published. In their submissions, applicants should describe / illustrate only a design intention which includes the focus of their energy concept. It is understood that the detailed development and implementation of the design and concepts will be carried out and completed by the Teams after selection as a participating Team. In combination with the urban situations, Teams can start to plan. It is a ready-to-use package.
situations & options
Please note that Teams are free to propose one of the three urban situations as applied to their city of origin, or choose one of these situations specific to Wuppertal. In the case that a Team elects to apply a situation to their city of origin, they will need to provide similar information to make the circumstances and the approach visible for the jury. Prospective Teams are invited to understand the three situations with their corresponding parametres and principles as these could be applied and contextualised into the Teams’ choice city.
a neighbourhood with potential
The Mirker Quarter is a central, mixed urban neighbourhood that has evolved over time. Characteristic for the Mirker Quarter as well as for Wuppertal is the hilly topography. The building stock, which comprises more than 800 buildings, largely consists of typical buildings from the end of the 19th century, mixed with post-war buildings from the 1950s and 1960s, This is representative for many urban neighbourhoods in Germany and throughout Europe. Some buildings are already renovated, others are in their original condition. The energy infrastructure consists of a natural gas and power grid of the local utility (https://www.wsw-online.de/). Existing buildings partly use solar systems or combined heat and power units.
For more information about the energy classification of the existing building stock in Germany, see http://webtool.building- typology.eu/. Due to the damage after the Second World War and the resulting development of the city, numerous curious urban and architectural situations have developed. However, the quarter and neighbourhood has potential for urban densification and offers interesting and realistic planning tasks for the Solar Decathlon Europe 21 with great opportunities for multiplication. The district is well connected for pedestriants to the city centre. Private parking is very limited.
urban and architectural challenges towards climate neutrality
The further development of future cities towards climate neutrality is a central topic in Europe, see Baukultur Report Heritage – Presence – Future 2018/19. Urban revitalisation, and the changinglifestyles of city dwellers, make innovative densification concepts and the adaptation of existing building stocks necessary. Against this background, and associated with the challenge of urban mobility, the SDE21 addresses three urban situations:
1_ renovation & extension
2_ closing gaps
3_ renovation & addition of storey
All three situations exist in the Mirke district, in Wuppertal. For those Teams proposing a comparable situation from their home town / country, documentation of the existing conditions must be provided.
1_ renovation & extension
Renovation is an important step towards the transitions of cities. Specifically, buildings constructed after the Second World War are no longer suitable for the city of tomorrow. Often constructed with inexpensive building materials, insufficient insulation and inflexible floor planning, these buildings present low-quality living for the city residents of tomorrow. The transformation of these buildings makes them attractive, integrating them into urban energy transition. The concept of inner courtyards in overall strategies may increase quality of life. The renovation may be combined with an extension of the existing building to create more living space and optimize space efficiency.
Neighboring development:Heterogeneous residential development around 1970.
Building situation: One of the two twin buildings is to be transformed and extended. An extension is possible either to close the perimeter development or to the inner courtyard. This depends on which building the team will focus on; see Axonometry. The head building is available for planning, i.e. it can be included in the planning, but does not have to be. It can also be demolished.
Site concept: The inner courtyard, which is currently used as a parking lot for the residents, is available for the development of a superordinate site concept. If the head building is considered in the planning, it can be included in the site concept as well.
2_ closing gaps
Within the city, undeveloped areas surrounded by two or more buildings are designated as vacant lots. Closing these gaps is a favourable possibility to increase urban density. In parallel, innovative architectural and energy supply solutions for these gaps can repair the cityscape and inspire an entire neighbourhood including its energy supply.
Neighboring development:To the right and left of the gap there are 4-storey residential buildings with east-west oriented pitched roofs, partly with small salesrooms on the ground floor. To the east, the site borders on a cemetery.
Building situation: This is a typical urban gap. The neighbouring development closes with fire walls. The planning task is to fill the gap in the construction site taking into account the direct neighbours.
Site concept: Three neighbouring buildings to the left and right of the gap and the open space on the opposite side of the street are available for the development of an overarching site concept. Currently, the open space is a public green area with a playground and a football field.
3_ renovation & addition of storey
The addition of one or more extra storeys to an existing building, including the renovation of an entire building, is a great opportunity for the proposal of new design ideas and the creation of alternative living spaces, thus sustainably increasing urban density. The addition of storeys is often found in residential and office buildings. In urban areas, warehouses and old factory buildings are also being extended more and more frequently. The diversity of use revives the urban space. Roof top extensions create a platform for intensive solar energy utilization.
Neighboring development:The neighbouring development is very heterogeneous. In the east there is an intact perimeter development with housing, built around 1918; in the south and north, newer residential buildings from 1980 are situated.
Building situation: The purpose is to create additional living space by adding storeys. The café-restaurant enjoys great popularity in the neighbourhood and should remain on the ground floor.
Site concept: The site north of the object is available for the development of a superordinate site concept. Currently there is a separate area where the terrace of the café-restaurant is located. The eastern area is used as a parking lot.
choose one urban situation & handle both challenges
As described in the Call for Teams, the whole project splits up into a design challenge for the whole building project and the challenge to build and operate a Demonstration Unit (similar to SDE units from past competitions).
building design challenge:
The requirements for the building designs are similar to an architectural design competition. A design and energy concept for the whole building needs to be developed following the idea of carbon neutrality.
- Scale: 1:500 site plan,
- 1:100 ground plans, sections and elevations,
- up to 1:5 for architectural details
A continuing part of the building design is the site concept: Besides the building design task,the surrounding neighbourhood is described. On a conceptual level, it offers the possibility to address neighbourhood solutions such as open space design, shared spaces, energy networks, urban mobility solutions etc.
- Scale: no scale defined, conceptual level only
The Demonstration Unit is part of the completely designed building. The teams are free tochoose the most representative part of their building design, but solar systems have to be integrated.
- Scale in planning phase 1:50 up to 1:2 for architectural details,
- build in scale 1:1.
