  • Building the future means taking responsibility

    Building the future means taking responsibility

    Mr Binkert, you have been working in property development for decades. What drives you personally and what is your vision for the future of architecture and property development?property development is also spatial development. With every building, we change our environment, the space around us. This change should be an improvement, not a deterioration. I am concerned with the question of the rules that we must observe to ensure that our built environment remains sustainable, liveable and fit for the future. I see the future of property development in creative, holistic planning that combines social needs with technological possibilities and puts people and the environment at the centre.

    Which project has had a particular impact on you?
    Every project broadens the horizon of experience – but Greencity Zurich was a turning point for me. It was the first time we developed concrete rules for Losinger Marazzi on how a neighbourhood has to be planned, built and operated in order to be considered truly sustainable. This project showed me how profound an impact sustainability can have when it is systematically thought through and implemented. The fact that Losinger Marazzi emerged as Switzerland’s first “green general contractor” was a strong sign that sustainability can also be a model for economic success.

    As President of the 2000-Watt Smart Cities Association, you are committed to sustainable and energy-efficient cities. How do you specifically integrate sustainability aspects into your projects?
    In Greencity Zurich, we developed comprehensive rules for the planning, construction and operation of a sustainable urban district for the first time. This resulted in the “2000-Watt-Areal” label, which has certified over 50 urban neighbourhoods throughout Switzerland. Today, we are developing it further under the authorisation of the Swiss Federal Office of Energy – with a view to the smart city. We were recently able to certify the first project in India.

    The biggest challenge remains the balance between ecological, social and economic sustainability – especially internationally. In China, social demands are difficult to realise, in Brazil there is often a lack of environmental understanding, in the Emirates economic efficiency is not an issue. In Switzerland, too, it takes empathy, understanding and perseverance to implement viable, sustainable solutions.

    You have international experience, including in the USA and India. What differences and similarities do you see in urban development between Switzerland and these countries?
    The main difference lies in the pace of growth: emerging countries with rapidly growing populations need a lot of new space quickly and cheaply – often at the expense of quality. There, sustainability is a promise for the future that is often met with scepticism. Sustainability costs a lot in the short term, but only yields returns in the long term, but then, according to our assumptions, it covers the costs many times over.

    In the western world – where growth is stagnating or declining – other values take centre stage: social justice, the circular economy, biodiversity. Here, sustainable development is increasingly seen as a prerequisite for quality of life. However, the demand that the West must also pay for sustainable development in emerging countries is also pushing wealthy countries like Switzerland to their limits.

    What trends do you see in future urban and area development and how do you envisage the forms of housing of the future, particularly with regard to demographic change, increasing urbanisation and densification?
    We are at a turning point. The construction industry urgently needs to catch up in areas such as digitalisation, automation and artificial intelligence. We are still building “brick and mortar” – as in Roman times. While basic human needs have hardly changed, the technical possibilities certainly have. The megatrends – demographic change, health, the future of work, the climate crisis – require new answers to the question of how we live. We must have the courage to question the status quo, break new ground and try out solutions that did not exist in the past.

    The “housingisation of Switzerland” cannot continue. What used to work in a Switzerland with 6 million inhabitants and limited mobility is now leading to collapse. We need to see ourselves more as part of the universe again, in which we are just one of many species – not as dominators. Every day we see the consequences of our short-sighted use of finite resources, diminishing biodiversity and the waste of energy.

    In future, we will move closer together, make space for others, live more efficiently and with greater sufficiency. To ensure that this does not diminish our quality of life, we need to make better use of the technological opportunities that are already available to us today and those that we will develop in the future. We will live more urbanised lives than we do today, we will meet our daily needs within walking distance and we will be better connected.

    We have now reached 9 million inhabitants in Switzerland. The property industry has been talking about a Switzerland of 10 million for some time now. In your opinion, are we sufficiently prepared for this and where do you still see a need to catch up?
    The idea of a Switzerland of 10 million is already outdated. If we want to enable our ageing society to live comfortably, we need an additional young and well-educated workforce – we need a 12-million-strong Switzerland! We must offer sustainable solutions to the expected migration flows of climate refugees and war refugees without jeopardising our culture and history. The faster and better we prepare for this, the more we will be able to benefit from it.

    We are ill-prepared for the exogenous paradigm shifts. Although we are aware of the pull of the big cities, we do not offer any alternatives. We still work with zoning plans, even though these are no longer able to reflect our production and our way of life. We stare spellbound at the successful crowd-pullers of Zurich, Basel and Geneva instead of recognising and exploiting the dormant qualities of small towns such as Lenzburg, Brugg, Wetzikon or Glarus. There is an urgent need to catch up here.

    Our vision of Smart City Switzerland is not a megacity with a sprawling agglomeration – quite the opposite: we are proposing to become more compartmentalised again. It is not the large Swiss cities that should grow, but the medium-sized and well-connected smaller cities that should become denser and more urbanised – with plenty of green space in between. Urbanisation includes the improvement of amenities, cultural enhancement and, in particular, the creation of new jobs. And where research on settlement development identifies gaps in the urban network, we must also have the courage to build new cities.

    What roles and long-term vision do you see for the Glarus economic region and which key projects will characterise the coming years?
    Glarus North is the economic backbone of the canton – with its location, infrastructure and proximity to the Zurich economic area, it offers enormous potential for production and services. Glarus South, on the other hand, scores highly in terms of nature, recreational value and quality of life. These two areas should be considered much more in terms of a functional symbiosis. The Glarus 2030 vision shows clear prospects for this, but it needs to be supported more broadly. Key projects in Näfels-Mollis and Niederurnen-Oberurnen would be ideal catalysts, but have so far been underutilised – not even in the recently adopted municipal structure planning. Narrow cantonal and federal regulations on building zone dimensions are slowing down development – there needs to be room for manoeuvre for future-oriented solutions.

    One of your students’ Master’s theses analyses Glarus North as a potential sub-centre in the Zurich economic region. How do you assess the development potential of this region, particularly with regard to infrastructure, industries, jobs
    and housing?

    The potential of Glarus North is impressive. Our studies on Smart City Switzerland show that there is space for a medium-sized city on both sides of Lake Walen – but whether this is created in Glarus North, Ausserschwyz or Sarganserland ultimately depends on the political will of the residents.
    The aforementioned HSLU master’s thesis examines the relationship between the large city of Zurich and the surrounding sub-centres (nodes of second centrality). The current situation of the brain drain and the salary mercenaries who commute back and forth between rural Glarus and urban Zurich is contrasted with the vision of the 15-minute town of Glarus Nord. The master’s thesis confirms the interdependence of spatial planning and economic development, of densification and diversity of use, of jobs and living space.

    What needs to happen from a planning and political perspective so that Glarus not only grows, but also helps to shape the future?
    From the perspective of Smart City Switzerland, the Federal Office for Spatial Development ARE must revise spatial planning throughout Switzerland and create new open spaces for densified settlement development. On this basis, existing cities can be densified or even new regional cities (nodes of second centrality) and small towns (nodes of third centrality) can be developed.

    For Glarus, this specifically means active lobbying in Bern to position Glarus North as a business location. This is the only way for the canton to free itself from the role of passive follower in financial equalisation. A clear decision needs to be made between a wait-and-see approach and active participation. If you want to help shape the future, you have to invest – in planning and development, infrastructure, location marketing and political persuasion.

    What role does the cantonal structure plan play in this and what influence can be exerted at communal level?
    The cantonal structure plan reflects the current situation and takes a linear approach. It does not reflect the paradigm shifts that we will be facing in the coming years. The structure plan also offers insufficient flexibility to be able to react to the new exogenous and endogenous challenges.

    The scope for influencing the overarching structure plan is limited. The municipality is dependent on the canton, and the canton in turn is dependent on the federal government. In addition, the requirement for planning consistency makes any innovation difficult. The reaction times are too long. Nevertheless, there are levers: pilot projects and development centres (ESP) make it possible to test innovative ideas and try out new urban models.

    Today’s 105th immoTable in Glarus makes an important contribution to the urgently needed discussion on whether Glarus wants to become a location for the future.

  • Careful transformation of the Papierwerd site resolved

    Careful transformation of the Papierwerd site resolved

    The Papierwerd site is to become a public place that is well connected to the adjacent urban space and invites people to stay, meet and exchange ideas. With this in mind, the city council has agreed to a careful transformation, in which the open space offer in particular is to be increased. The direction of development is based on the results of the “Forum Papierwerd” dialogue process and takes into account important framework conditions, such as the need to protect the temporary Globus building and water protection. How far the redevelopment of the Papierwerd site will go and what it will involve in detail is still open.

    Strategy process for the Papierwerd site
    The Papierwerd site strategy process was used to develop the basis for a broad-based decision on the future of the site. The core of this process is the “Forum Papierwerd” dialogue procedure carried out in 2022, in which experts from various disciplines, representatives from politics, associations and other organisations as well as the population participated. The process revealed that both structural and use-related changes are necessary for the desired opening and changeability of the area. The results are recorded in eleven central statements that contain important aspects for the future of the village.

    Immediate measures
    The transformation of the Papierwerd site will begin as soon as possible. Where changes in the sense of the results of the dialogue process are feasible on a low-threshold basis, (temporary) immediate measures will be implemented from 2024. For example, an upgrading of the open space south of the Globus temporary building or a more open, transparent design of the ground floor façade in the entrance area of the station bridge are planned.

    Next steps

    In an in-depth phase up to the beginning of 2025, various construction-related questions will be clarified and the handling of the Globus provisionals’ worthiness of protection as well as water protection will be further discussed. In the subsequent project phase, which is estimated to last until 2026, a competition will be held. This will be followed by project planning and the approval procedure. All work on the Papierwerd site should continue to be carried out transparently and in dialogue with the various parties involved.

  • Werkstadt Zurich: Transformation into a climate-friendly neighbourhood

    Werkstadt Zurich: Transformation into a climate-friendly neighbourhood

    SBB is transforming the 42,000-square-metre Werkstadt site in Zurich into a vibrant urban space, to be completed by 2035. This will preserve the fabric of its historic buildings, which will one day be joined by both new buildings and extensions to create an exciting cluster. The transformation of the former SBB workshops will be exceptionally sustainable, featuring climate-conscious building measures, circular economy elements and an innovative energy concept.

    Developing existing buildings
    In close coordination with the monument preservation authorities, the existing buildings will be gradually renovated and joined by new buildings and extensions in the coming years. At the heart of the site, the former carriage workshop ‘Building Q’ will allow for a diverse usage mix under one roof from 2023. The development will offer an exciting interplay between the fabric of historic buildings, structural densification and public use of outdoor space.

    Environmentally friendly construction
    ‘SBB wants to be climate-neutral by 2030, and climate-compatible construction is an important factor in achieving this objective,’ said Gabriele Bühler, Project Manager at SBB. Various climate-conscious building measures have been incorporated into the planning of the site. That includes configuring the new buildings to promote the circulation of cool air currents. Where possible, the roof water will be allowed to seep into an above-ground system for further cooling. Surfaces will remain unsealed where possible. The transformation follows a systemic approach that considers the building along its entire life cycle. The aim is to keep CO2 emissions as low as possible. To ensure circularity, all construction components are recorded on the Madaster platform. There is also a particular focus on reusing components. 

    Energy concept: 100% renewable
    ewz was able to win SBB’s public tender with an energy solution based on 100 per cent renewable energies. Groundwater, which is collected in four wells on the site, serves as a source of heating and cooling. From these wells, the water flows to the energy centres in the larger buildings, which house heat pumps and cooling machines that bring the water to the required temperature. An anergy network connects all the buildings and ensures that excess energy is exchanged between the building groups. For example, excess heat or cold in one building can be used in another. This system also has the advantage of not requiring groundwater boreholes in every building: the smaller buildings are connected to the energy centres via a local heating network. Heating and cooling is generated without any CO₂ emissions, as the rest of the electricity also comes from renewable sources. The use of a monovalent energy system will ultimately lead to a CO2 reduction of over 2,100 tonnes per year.

    High self-consumption of solar power
    ewz also plans, finances, creates and operates the transformer systems and medium-voltage lines to supply the site with electrical energy. ‘Some of the electricity that the people in the Werkstadt use on the site is produced there using photovoltaics,’ explains Markus Fischer, Head of Sales at ewz Energy Solutions. To this end, SBB and ewz want to make the best possible use of the roof areas for solar power production. Both the roof of Building Q, at the centre of the site, and the roofs of other buildings with a suitable structure and orientation for generating solar power are to be kitted out with photovoltaic systems. SBB requires its tenants on the site to form a self-consumption association (ZEV). ‘When completed, the ZEV will consist of around 300 parties that will use locally produced electricity on the site. This allows us to achieve a high self-consumption rate, which, in turn, makes a significant contribution to the cost-effectiveness of the photovoltaic systems,’ says Markus Fischer. He expects self-consumption on the Werkstadt site to be almost 100 per cent when completed.

    The benefits of contracting
    For the owner, this form of collaboration has various benefits, including keeping financial risks and management costs very low. If a system fails, ewz makes sure it gets back into operation as quickly as possible. To ensure that the system can be operated efficiently, ewz will start undertaking energy-related operational optimisations shortly after commissioning. As part of an ongoing process, the systems will be optimised and adapted to the actual needs relating to their use. By extension, this ensures that they consume as little energy as possible, generate minimal costs and offer maximum convenience for users.

    Werkstadt Zürich is a successful example of a forward-looking approach to repurposing a historic industrial site. With the targeted renovation and expansion of existing buildings and a ground-breaking energy concept, the developers – together with the planners and ewz – are creating added value for future users and the environment alike.
