The Volkspark Prenzlauer Berg in Berlin was created on the rubble of Alexanderplatz. Today, few people stray into the thicket of the seemingly wild park – but it is a valuable habitat for numerous wild animals. In the winter semester of 2022/23, Master’s students of landscape architecture and environmental planning at TU Berlin explored the park in a design studio. Professor Stefan Reimann, who led the studio together with Professor Barbara Hutter, introduces the background to the students’ work.

It’s not just in our September 2023 issue that we make space for student projects. Students also present their own work here on our website. You can find all the projects on our “Studies” topic page – and the September issue is available in our store.

The Volkspark Prenzlauer Berg is a 29-hectare park on the eastern edge of the Pankow district of Berlin – created from the former Oderbruchkippe. A group of 14 master’s students at the Institute of Landscape Architecture and Environmental Planning (ILAUP), Department of Landscape Architecture/Object Design (FG-LOB) at the TU Berlin took a closer look at the park. The design studio “Into the wild” took place under the direction of Professor Barbara Hutter and Professor Stefan Reimann in the winter semester 2022/23.

The western part of the park is formed by a double peak of rubble, which at its highest point rises around 90 meters above the level of the surrounding urban quarters. Originally, allotment gardens and detached houses were built here from 1871 onwards as part of Berlin’s industrial boom. After 1945, when reconstruction began, the rubble from Alexanderplatz was deposited here. The so-called “Oderbruchkippe” was created from around 15 million cubic meters of spoil. Topsoil was applied to the newly remodeled area and grass was sown. Pioneer trees (poplars, ash, maple, robinia, willows) were planted over a large area and later supplemented with higher quality trees.

The park was officially opened in 1969. As a result, a forest-like biotope was created with 60 percent woodland and 40 percent meadow areas. Since 1971 there has been a botanical nature trail, and from1979 there was a wetland biotope (now silted up) and an adventure playground (which also no longer exists). A toboggan hill remained as a simple relict, with sand bees settling on the edges. With 57 bird species and numerous other wild animals, it is a valuable habitat.

The Volkspark Prenzlauer Berg is captivating – both in summer and winter – with its wild, unpretentious, rough but atmospheric appearance. Few people stray into the impressive thicket or the high meadow plateaus. The dense vegetation does not allow any views of the surroundings. The porous subsoil of the rubble makes the trees appear parched in summer, suffering from the increasing drought. Deadwood is not removed, but left on site, to the delight of the fauna, and road safety is just about guaranteed. The asphalt paths are partly broken up, they rise and fall in waves due to the root pressure of the trees. The sparse, dilapidated facilities reinforce the neglected impression. A public park in a deep sleep, waiting to be discovered. The Pankow district office is aware of the need for action and extensive mapping of the flora and fauna is already underway.

The place immediately and permanently fascinated the participants with its special aura.

You have experienced the park in brilliant autumn leaves, on gray days with rain and fog. You know it with muddy leaves, in winter with snow as well as its savannah atmosphere in scorching heat and drought in August. The variety of shaggy, vegetative structures and their haptic, sensual qualities in an urban context are surprising, as are the thousands of trees and many animal species that are known but remain largely invisible to visitors, just like the lush topography of the park.

In the studio, this special aura of the place was to be taken into account by attempting to design three characteristically pointed variants. The variants do not seek compromises between the different interests, but deliberately show a clear edge. A theme should be worked through consistently down to the last detail.

Three scenarios were specified for the design work:

Animal Park: Is this allowed in an urban context, does it make sense? A park where the focus is on the animals and not the people, where habitats for animals are not developed as an alibi, but consciously on an equal footing, at least striving for coexistence. Careful handling of the valuable stock and clever visitor guidance play a special role here.

Climatize: Climate control, the big issue of our time, is the second scenario. The focus here is on adapting the park to climate change. How can the park’s tree population be developed sustainably, i.e. for the future, through transformation? What can contemporary rainwater management look like at this point?

Human Nature: In this scenario, the focus is on people and their (special) needs for this place with its special character. A park also tailored to unusual uses, downhill biking or climbing forest, nothing is impossible, plants and animals are rather secondary here.

With the dedicated support of Dipl.-Ing. Susanne Isabel Yacoub (laview) for landscape architecture and video, the studio initially began with a rational, classic analysis of the history of the site, the qualities of the urban and open space planning environment and the Volkspark itself. This was complemented by an emotional, sensual analysis, the feeling of the place with tours and joint brainstorming, a photo and video documentation. The students then worked on these individually in the form of an experimental analysis video, collages or as an installation and transferred them into an initial, quick weekly impromptu.

In the traditional way, the participants each developed a concept idea and worked through the design based on it individually. As a special feature, videos were also created that represent the students’ designs, an experimental novelty. This resulted in 14 very different works, which were worked through in detail in the design and explore the range of possibilities for this special place. The six works presented here represent excerpts from the variety of ideas and designs that were created as part of the “Into the wild” studio. All videos can be found on Instagram at @fg.lob.

The representatives of the Pankow district authority were delighted with the final presentation. They would like to purchase ideas and take up the studio management’s wish to make Volkspark Prenzlauer Berg fit for the future as part of a competition process.

Net zero and high building culture? But yes!

Advertorial Article Parallax Article

The Swiss planning associations’ “Baukultur climate campaign” aims to show that net zero can go hand in hand with high-quality Baukultur.

Switzerland is particularly affected by climate change. This is not the only reason why it has set itself the goal of reducing its greenhouse gas emissions to net zero by 2050. An initiative has now set itself the goal of communicating that net zero can go hand in hand with high-quality building culture. Swiss planning associations founded the “Baukultur climate campaign”. The BSA, BSLA, SIA, EspaceSuisse, the Swiss Heritage Society and the Monument Preservation Society have taken a clear stance on nine points in the initiative.

As an Alpine country, Switzerland is particularly affected by climate change. This is shown by temperature measurements that have been carried out since 1864: The average temperature in the country has risen by 1.9 degrees Celsius since measurements began a good 150 years ago. This is twice as fast as the global increase over the same period, which is 0.9 degrees Celsius.

Why is Switzerland affected more than average? On the one hand, it is because Switzerland is already characterized by a continental climate. As a landlocked country without access to the sea, there is no large body of water to cool Switzerland. On the other hand, the country is located in the mid-latitudes of the northern hemisphere. The areas north of the equator warm up more than those to the south. For Switzerland, this means dry summers, severe weather events, winters with little snow and significantly more hot days, especially in urban areas. The extent cannot be predicted exactly, but one thing is clear – it depends on the amount of greenhouse gas emissions in the coming decades.

This is where Swiss politics came in when Environment Minister and Federal Councillor Simonetta Sommaruga presented Switzerland’s new climate strategy. The aim of the strategy was to show how the country can reduceCO2 emissions and greenhouse gas pollution to net zero by 2050. Net zero means that a company or country eliminates all emissions as far as possible. The last few percent can ultimately be offset by carbon capture and storage (instead of emittingCO2 into the atmosphere, it is stored and permanently sequestered) and negative emissions technologies (the retrieval of greenhouse gases from the atmosphere). The bottom line is that Switzerland no longer emits any greenhouse gases – it comes out of the equation with a net zero.

Baukultur climate campaign supports net zero target

The Federal Council believes that achieving net zero by 2050 is feasible. Although the building sector currently accounts for a quarter of Switzerland’s greenhouse gas emissions, it is also responsible for 40 percent of the country’s energy budget. However, emissions in the transport, industry and building sectors in particular could be reduced by 90 percent by 2050. To this end, the federal government and cantons are promoting the energy-efficient renovation of buildings as well as investments in renewable energies, the use of waste heat and the optimization of building technology.

To support the goal of net zero by 2050, numerous players in Swiss building culture have now joined forces, from cultural heritage to architecture, landscape architecture and spatial planning. To be more precise: the associations BSA, BSLA, SIA, EspaceSuisse, Heimatschutz and Denkmalpflege. Together, they founded the “Building Culture Climate Initiative”, which aims to show how net zero can be achieved while preserving Swiss building culture. On its website, the initiative writes that “climate measures must be implemented with a high level of Baukultur. Investments and transformations must be future-proof, sustainable and of high Baukultur quality.”

Protected properties can also be renovated according to net zero points

This is how the Baukultur climate campaign describes the starting position. It also clearly defines its position, which it breaks down into nine points:

First and foremost is building culture. This should be high, i.e. holistically high quality in terms of design, sustainability and social aspects. Because, as the initiative makes clear in point two, net zero can also become a reality with a high level of building culture. The combination of consistency, sufficiency and efficiency should ensure this. Thirdly, the requirement for high Baukultur quality also applies to energy measures on existing buildings. Architectural quality can be achieved without reducing, complicating or increasing the cost of energy-efficient refurbishment.

The fourth point relates to reconciling the preservation of cultural heritage with climate goals. Energy efficiency measures are also possible on properties worthy of protection and can be aligned with climate targets. Protected objects are also net-zero capable. According to the initiative, “protected buildings are an inspiration for sustainability in practice. They deserve respect and tailor-made solutions. There is a lot of potential in the careful integration of new and existing architectural quality.” Fifthly, the Baukultur climate campaign also aims to ban fossil fuels from the building sector. However, the balance sheet also includes gray energy and resource conservation. This goes hand in hand with point six: the principle of the circular economy should become the rule and be based on the five Rs (refuse, reduce, reuse, repair, recycle). This also includes implementing fewer and smaller projects, using more durable products, planning more durable constructions and reusing building components.

Building culture climate campaign to network and position Switzerland

The seventh point is aimed at open spaces: Climate-adapted settlement development with sufficient open spaces and trees should go hand in hand with ventilation, cold air flows and intelligent water use. In short: green and blue infrastructure should be coordinated. For this to work, the initiative also calls for existing funding instruments to integrate a high level of building culture as an element for climate protection and biodiversity. Positive incentives would promote the achievement of climate targets with a high level of Baukultur. Last but not least, the Baukultur Climate Initiative has set itself the task of collecting scientific work and findings as well as relevant initiatives and making them tangible. It sees itself as a platform that networks and positions Switzerland within an international framework. At the same time, it aims to promote the development of expertise and advice, communicate good solutions and take economic requirements into account.

The core team of the Baukultur Climate Campaign consists of Stefan Kunz (Managing Director of the Swiss Heritage Society), Claudia Schwalfenberg (Head of Policy, responsible for Baukultur at the Swiss Society of Engineers and Architects SIA), Peter Wullschleger (Managing Director of the Swiss Association of Landscape Architects BSLA), Barbara Franzen (Managing Director of the Conference of Swiss Heritage Conservators KSD), Claudia Moll (Co-President BSLA) and Adrian Altenburger (Vice President SIA).

Multiple crises are currently forcing us to rethink. There are pandemics, floods, forest fires and war. How do we want to live and build in the future? We are facing many new challenges that require complex considerations and solutions. And it is precisely here that the knowledge and skills of the diverse and interdisciplinary field of heritage conservation are in demand. What contribution can heritage conservation and restoration science make in view of the worsening climate situation, the scarcity of resources and the energy crisis? We asked experts from various disciplines about this. You can read the answers in our new online series Zukunft Baukultur. Every week, we publish a specialist statement on www.restauro.de. Here isthe statement from Ralph-Uwe Johann, owner and managing director of Deffner & Johann, Röthlein

In view of the worsening climate situation, scarcity of resources and energy crisis, both specialist retailers and manufacturers are increasingly responsible for selling ecologically compatible products and providing information on correct and resource-saving processing. Deffner & Johann also sets this standard for itself and, with a view to environmental protection, tries to offer environmentally conscious solutions whenever possible. Conservation and restoration can make a significant contribution to the sustainable use of resources. The preservation and conversion of existing monuments offer enormous potential for saving building materials and energy as well as reducing CO2 emissions.

Furthermore, materials in their traditional use are often significantly more sustainable when the entire life cycle is considered. Traditional binder systems, such as lime or linseed oil, not only offer an advantageous eco-balance, but are also often more resource-efficient in terms of production and maintenance. A few years ago, these were still considered complicated to work with compared to “convenience products” from the building materials industry and were removed from the curricula of technical colleges. Today, they are often regarded as modern or innovative in Europe and presented by leading planners and architects as a solution for sustainable construction. Specialist companies in the preservation and restoration of historical monuments could even contribute their knowledge advantage in the processing of corresponding products. As an internationally active specialist wholesaler for materials, tools and equipment in the field of restoration and monument conservation, we also always ensure that transport is optimized for the supply chain and that resources are used in an environmentally conscious manner.
