The “National Platform for Urban Policy” (CIPU) enables cooperation between national, regional/intermunicipal and local level and initiates the debate around urban planning and development in Luxembourg. In addition to that, it raises awareness in the international context and informs about ongoing urban spatial planning trends and relevant topics in Luxembourg.

Aim

CIPU works on two levels: the European and the national level. While increasing awareness about spatial planning in Luxembourg in the international context, the platform simultaneously supports the cooperation between the local and the national level in Luxembourg. The central objective of CIPU has always been to provide a platform for exchange between the various urban policies and a multitude of municipal, national and European actors and enable cooperation – an objective which remains valid today. However, the practical topics have evolved across the years. The convention applies a focused and cooperative approach for its implementation.

Partnership

CIPU is based on an agreement between the Luxembourg Ministry of Energy and Spatial Planning, the Ministry of Housing and Ministry of Home Affairs as well as the cities of Luxembourg, Esch-sur-Alzette, Differdange and Dudelange. These partners constitute the core network of the CIPU. It is managed and organised by the CIPU which is run by Zeyen+Baumann in cooperation with Spatial Foresight. Depending on the subject, the platform’s activities are implemented in close cooperation with external partners, e.g. the Klima-Agence.

Genesis

CIPU was developed in 2010 to support the integration of the recommendations for urban development from the European level in Luxembourgish spatial planning policy. In Luxembourg, the debate on spatial development since the beginning of the 2000s has been marked by the adoption of the second Master Programme for Spatial Planning (PDAT) in 2003, the Integrated Transport and Territorial Development Concept (IVL) in 2004 and the revision of the laws on urban (2004) and spatial planning (2013, 2018). CIPU initially aimed at transposing the objectives from the “Leipzig Charter on Sustainable European Cities” from 2007 at the national level while involving Luxembourgish municipalities in the implementation of a national urban policy, and – at the same time – considering the objectives of the PDAT which has a guiding function for national and local authorities.

During 2017-2021, a thematic focus was set for each year: In 2017/2018 the activities were focused on affordable housing. The year 2019 revolved around the topic of major urban development projects, the years 2020/2021 focused on both climate change adaptation in urban development and the revitalisation of inner cities. Furthermore, in the course of 2021, CIPU addressed the changing framework conditions caused by the COVID-19 pandemic and work was carried out under the overarching title “City in Transition”. In addition to workshops and events, which were dedicated to concrete issues and enabled a direct exchange between the participants, the results of the discussions were processed in numerous publications for Luxembourgish and European planners. These were produced in close cooperation with the partners involved in the CIPU and the actors participating in the workshops. The CIPU documentation is thus a significant output that actively contributes to informing and developing the expertise of Luxembourgish planners. In order to finalise this phase of CIPU and to provide space for other important topics in the future, the “Journée de la Politique Urbaine” was organised with Luxembourgish planners and experts in January 2022. In a world café-like setting, the future perspectives for a “City in Transition” were elaborated as a summarizing statement of the CIPU 2020/2021.

Outlook

The main topics and activities for the next two years are described in an ambitious programme. It was developed in close cooperation with all involved partners by means of in-depth discussions about relevant topics. This action programme will cover the following topics:

  • multifunctional urban areas
  • energy concepts for large-scale urban projects
  • climate resilience and climate change impact in urban development
  • building cooperatives and alternative models for housing and working

Activities for 2023 were launched in May with the online lecture series (colloque) consisting of four presentations on energy concepts in the district “Roud Lëns”, the projects “NeiSchmelz” and “Wunne mat der Wooltz” as well as the energetic renovation of existing buildings in Differdange and a low-emission district in Strasbourg. Further steps in the implementation include interactive thematic workshops, an excursion and a concluding conference on the second thematic focus of multifunctional urban areas. For external communication, and awareness-raising, CIPU will inform about ongoing activities, publications and provide a collection of funding opportunities for municipalities on its website and social media. Furthermore, this blog will inform continuously about ongoing urban planning and development trends and projects in Luxembourg – so stay tuned during the next months.

The Grand Duchy of Luxembourg, at the heart of Europe, continues to gain about 2% in population every year. The South of the country, the former industrial area, is growing especially rapidly, by a quarter since 2010 and in 2021 it hosted a third of all residents. Demand for housing has increased and is one of the most rapidly increasing expenses for Luxembourg households today.

In the already urbanised South, many large-scale development projects for new districts on industrial brownfields are being realised or are in the pipeline. This impacts the urban morphology of the area. Formerly geographically separated urban districts are now connected. But how can new districts interconnect urban fabrics, let alone urban functions? Differdange, the third largest city in Luxembourg, is home to such a brownfield project, ‘Plateau du Funiculaire’.

Rationale for action

The rapid development of the steel industry in Luxembourg during the 19th and 20th centuries created a unique urban tissue in the South. Housing was built around steel mills, as in other industrial areas. This resulted in large industrial zones being next to urban centres. In some cases, as in Differdange, these industrial zones are ‘wedges’, impermeable barriers that separate districts functionally.

Steel production in Luxembourg has declined over several crises and steel mills have reduced or entirely stopped production. Around 2000, some 25 hectares became available in the centre of Differdange. The ‘Plateau du Funiculaire’ was formerly a landfill for the adjacent steel mill.

Objective

The Plateau du Funiculaire functionally split several Differdange districts, so plans were drawn up to transform the brownfield site into a new urban district. From 2004, the city has developed urban concepts in cooperation with many local and national players. A new district, providing housing, offices and commercial areas is planned to connect the existing districts of Differdange, Oberkorn and Fousbann.

Some challenges had to be addressed in developing the urban concepts, including pollution of the area due to its use as landfill for the blast furnace. In addition, the river Chiers running through the area was planned to be renaturalised, to provide water retention and flood areas.

Time frame

The first scoping studies were realised as early as 2004. Since then, planning and construction has been ongoing with most of the district being finalised in 2020. Final construction during 2022 will complete the project on the former landfill.

Key players

The key player for developing the new area was the city of Differdange. The urban concept was developed with a Luxembourg planning office as well as an investor.

Implementation steps and processes

Following the first plans to develop the district in 2000, initial research in 2004 assessed the landfill pollution. At the same time, the city of Differdange also outlined strategic objectives for the district. In 2005, a planning office proposed the look and feel of the new district as an urban concept. Development started in 2006 when the historic ‘Villa Hadir’, a former reception and administrative building for the blast furnace was refurbished. Plans to implement the urban concept were submitted for building permits.

A brand was created in 2007 to establish an urban identity to market the new district to future inhabitants, businesses and commerce. Work on the infrastructure started in 2009 and the first bricks for the residential buildings were laid in 2011. In the same year, the recreational park was finalised, allowing neighbourhood residents to get to know the new urban district. Around 2019, a late change to the project integrated a multi-functional tower, called ‘Gravity’, increasing the number of planned housing units from 650 to 728.

Required resources

The resources used are not known.

Results

After a bit more than a decade of construction, the new district will be finalised in 2022. Within 10 years, 728 housing units have been created, providing accommodation for more than 1,600 people. The district also features 15 km2 of office and retail area. A school, a section of Luxembourg university, public administrative offices and shops complement the housing so the district is a fully developed urban quarter of Differdange.

A new train station links the area to the national railway network. In addition bus connections as well as bike and pedestrian infrastructure connect the district both internally and to the surrounding areas.

To minimise soil sealing, ‘Plateau du Funiculaire’ is high density. Nevertheless, some polluted parts of the former landfill were sealed with an artificial layer of clay so surface rainwater can drain into the nearby river. Rainwater that penetrates polluted soil layers is collected separately for treatment.

Experiences, success factors, risks

The relatively short construction period of ‘Plateau du Funiculaire’ highlights good preparation. Potential obstacles were identified, and solutions developed to avoid these.

The urban concepts and building permits provided planning security. The late modification to include a multi-functional tower in the district shows the project adapted to changing demands. Such flexibility is important as needs and requirements usually change for decade-long large-scale urban development projects.

Conclusions

‘Plateau du Funiculaire’ is a prime example of a successful large-scale brownfield development project. Such projects can close functional gaps between urban districts, offering new housing and commerce. In addition, interests from multiple public and private stakeholders can be addressed in one go. It also shows innovative approaches to issues like polluted soils that are frequently encountered in brownfield developments.

‘Plateau du Funiculaire’ also underlines that brownfield development offers much more freedom compared to developments in existing urban areas. Measures can be discussed before being realised in detail, helping to avoid conflicts.

In addition, brownfield development projects such as ‘Plateau du Funiculaire’ are testbeds for new approaches and technologies. The size of the district meant that planners faced challenges that could not be solved with existing planning approaches. An example is heating for the residential units where a centralised district heating system was planned as early as 2007 to reduce infrastructure costs and save energy.

Today the district offers a new face for Differdange and combines different urban functions in an optimal way. With multiple housing and commercial possibilities, ‘Plateau du Funiculaire’ will eventually become the new centre for the town.

Cities are hot spots of ecological disruption due to excessive consumption of natural resources and high pollution by inhabitants. At the same time, cities are also creative spaces where existing models and rules are challenged, and alternatives are developed and tested.

‘Eco-districts’ and ‘eco-villages’ are new approaches and concepts that are being tested in urban areas. With principles such as ‘zero-waste’ and the circular economy becoming increasingly popular, these initiatives currently experience a renaissance with great interest of the public, decision-makers and urban planners.

Rationale for action

Circular economy has become a trend topic in Luxemburg during recent years. Decision-makers, urban planners and building research investigate new techniques and materials to render urban construction following the ‘zero-waste’ principle and the principle of circular economy.

At the same time, the demand for products that are produced in an ecologically and socially viable way increases. Alternatives to our established consumption model become more mainstream and promote alternatives to the linear economy of today. Many grassroot initiatives benefit from this recent trend towards a more circular approach in construction and an increasing demand for alternative products. BENU village has committed itself to this idea and in doing so has become the first eco-village of the Greater Region.

Objective

BENU village, (neologism for “Be New”) is the name of a grassroot movement in Esch-sur-Alzette. Its objective is to showcase that alternative models to the mainstream way of building and consuming are possible, and so in Luxembourg.

In this regard, the construction of the first eco-village of the Greater Region follows circular economy principles and also the economic activities are committed towards recycling, reusing and upcycling.

Time frame

The idea to create the BENU village first came up in 2015. A private person had the idea, which soon came to realisation. In 2017, the construction of BENU village started and the first building was finalised at the end of 2019.

Key players

To formalise the idea and to increase its visibility towards the public, the city and the state, an association was founded to endorse the implementation of the eco-village: “BENU Village Esch ASBL”. The association is financially supported by the municipality and the state.

During the realisation, other state players became interested in the project. Businesses and state services use the premises of BENU village. For example, the national integration service for young adults organises learning programmes in BENU village.

Implementation steps and processes

All building materials used for the construction of BENU village derived from either re-use or recycling. Since the start of the construction in 2017, many volunteers have supported the building of the first house, which was finalised at the end of 2019. In addition to the volunteers, the project was supported by local craftsmen and other businesses that provided knowledge and materials.

In the building process of the village, considerable attention was devoted to the use of recycled materials. During the construction, only the screws were purchased new, the remaining materials, for example the windows, the wood used for framing, the insulation and the exterior shell of the houses, were entirely recycled from waste.

Soon after the first building was realised, shops moved in. The founder and initiator of BENU village opened “BENU Couture”, a tailor shop that produces clothing from used materials and second-hand articles. The premises continue to grow and were opened for other interested professionals.

A Charta, the so-called “BENU Charta” formulates shared values that ought to be respected by all businesses and professionals working in the eco-village, was developed. The Charta puts an emphasis on the ‘zero-waste’ principle, the recycling and upcycling of materials and commits future economic activities in the eco-village to act in an environmentally and socially responsible and transparent way.

Required resources

BENU village benefits from seed funding of the Ministry of Energy and Spatial Planning and the City of Esch-sur-Alzette, where the initiative is located. Apart from the financial support, the project was realised with the support of volunteers, that helped in the building and organisation of BENU village. As the building materials were mostly recycled, no material costs arised from the implementation of the project.

Results

The numbers speak for the success of the eco-villager: in 2019, a turnover of EUR 210,000 was generated, with 18 persons working for BENU village. About EUR 80,000 were generated from upcycled clothing and accessories. And BENU village will soon grow further. In 2021, when more surfaces of BENU village will become available, they will be rented to professionals pursuing similar ideas. Interested businesses, that act in line with the BENU Charta, can then rent these spaces. This way, BENU village will develop into a coworking space of likeminded professionals and businesses.

BENU village shows that there are different interpretations of the often referred-to ‘circular economy’. In addition to the mainstream definition, applied mostly at regional and national level, the definition of BENU village is different. BENU village shows an alternative reading to circular economy that functions at small scale and yields more than just a decrease in material consumption.

Experiences, success factors, risks

As with many grassroot movements, the private commitment to the underlaying idea is important for the success of a project. The idea for BENU village was initiated and implemented by a private person. The continued lobbying and defence of the idea has successfully yielded the interest of elected officially, such as several national ministers and even the Grand Duke of Luxembourg.

In 2021, the project was awarded with the European Climate Star from the Climate Alliance in the category ‘Saving resources’. A short video is available here.

Conclusions

BENU village shows an alternative to our current living and working in an affluent society. Ideas such as ‘zero waste’ can also be successfully implemented with relatively little resources at district level. However, for doing so one needs pioneers and “BENU is a pioneer”, as described by the national Minister for Energy and Spatial Planning, Turmes.

The idea behind BENU is versatile and can be applied for more than just material production. During 2021, a restaurant, following the BENU Charta will open at the premises of BENU village.
