Here she spent two years as deputy head of the Urban Climate/Climate Change Department at the Frankfurt Environmental Agency before moving to the Frankfurt Climate Department when it was founded.

Climate-neutral by 2035 – the city of Frankfurt has set itself ambitious goals and established its own climate department to achieve them. It began its work in January 2023. Jana Leoni is part of the 21-strong climate department team. We spoke to the urban planner about bureaucracy in planning and asked her how well Frankfurt is positioned in terms of municipal instruments in her opinion.

The interview was conducted and published in June 2023!

Jana Leoni, At the beginning of the year, Frankfurt city councillors set a clear national example by making the greening of facades and roofs mandatory for new buildings and conversions. They also declared war on gravel gardens. A success? Or do you think more is needed?

The design statute “Open space and climate” and the accompanying information brochure are not only intended to shape building law, but also to provide assistance for climate-adapted construction. After all, just like a gravel garden, an unplanted flat roof, an unplanted façade or a treeless plot that drains into the sewer also represents a wasted opportunity for a better urban climate. And this is precisely what needs to be communicated and everyone involved in the building project needs to be aware of this. Of course, changes also need to be made to existing buildings. Here, Frankfurt is helping private applicants to make the climate-adapted design of their properties as simple and attractive as possible with the “Frankfurt Frischt auf – 50 % Klimabonus” funding program.

In the eyes of many, complex bureaucratic processes in Germany’s municipalities often make it difficult to implement innovative projects quickly. How do you see this? Do we need less bureaucracy to combat climate change and heat?

Criticism often overlooks the complexity of the requirements. In Frankfurt, however, the processes are nonetheless running smoothly. The building inspectorate is quick and efficient when it comes to project approval. If you are interested, there is also the option of climate consulting with our team, quickly and unbureaucratically. The handling of consultations and funding allocations in our funding program is also subject to a streamlined, uncomplicated procedure. The process is constantly being optimized and, according to the plan, digitalized.

The complexity of the issues applies even more to public spaces. Nevertheless, once a measure or program has proven itself, it generally works very well. For example, the drinking fountain programme, which has picked up speed after a long start-up phase and is now being implemented fountain by fountain. In the streets, there are more and more flowering islands on former traffic areas and the sponge city theme is taken into account in all new planning. So experience tells us to “keep at it”. And we in the climate department are personally committed to implementing great innovative ideas as unbureaucratically as possible.

How many technical options does the municipality of Frankfurt have to prevent the heat island effect? In other words, how well is Frankfurt positioned in terms of municipal instruments? Where do you see room for improvement?

There are already a number of existing instruments, such as the “Frankfurt Adaptation Strategy 2.0” or the “Climate-adapted urban square design” guidelines. The guideline was based on the planning for the redesign of Paul-Arnsberg-Platz, which is now the first square in Frankfurt to be redesigned in a climate-adapted way. Another one is currently being planned. As a city and together with the private sector, we can achieve a lot with tools like these.

The state of Hesse published the Hessian Heat Action Plan this February. How important is this for your work?

The Hessian Heat Action Plan shows that long-term preparation for a heat event is just as essential as concrete measures for acute heat events. In Frankfurt, the long-term measures are regulated in the adaptation strategy. A “Climate Change Action Plan” (KWAP) is dedicated to acute measures. The city wants to be comprehensively prepared for all extreme weather situations – heat, drought, storms and flooding – in order to protect people, animals, plants and infrastructure in Frankfurt.

Frankfurt am Main wants to be climate-neutral by 2035. Your department was set up in part to support this goal. In your opinion, where does Frankfurt currently stand in terms of climate neutrality? What are the biggest challenges?

Even without mentioning the current figures, one thing is certain: we still have a long way to go, which we want to achieve in a short, intensive period of time. A major, but also positive, challenge is to recognize the potential and to determine and implement the most effective measures. Solar installations on buildings and open spaces, a mobility turnaround and a turnaround in the construction and real estate sector, the use of renewable energies and waste heat are currently considered to be the most effective strategies that need to be implemented as a priority in the coming years. “Calculated climate neutrality” also includes the goal of a liveable, climate-change resilient city of Frankfurt. Our current 21-strong team, led by Hans-Georg Dannert, is looking forward to these challenges and is ready and eager to take this path together with the administration and urban society as a whole.

Do you sometimes lack an overview? That happens to us too. That’s why you’ll find news, discussions and planning projects well organized here. September 2022 in retrospect.

Let’s start with some good news: in September 2022, the bdla published a Pixi book on landscape architecture entitled “Landscape architect Lena plans a park for everyone”. The 24-page book focuses on the profession of landscape architect.

Events for planning

In September, the Biennale of Urban Landscape was also held for the first time at the Gelsenkirchen Science Park. Over the course of two weeks, various stakeholders interested in the future of the urban landscape in the Ruhr metropolis came together. The special thing about it: The IBA Emscher Park started at the same location over 30 years ago.

The IAA will take place again in Munich in September 2023. Since 2021, the former motor show has presented itself as a major mobility event. However, the new trade fair concept has not only been met with praise. Find out more about the discussions surrounding the IAA 2023 here.

Also interesting: The bdla is organizing two interesting events at the beginning of October. The bdla Designer Days in Berlin and the Sustainability and Climate Adaptation symposium.

Park(ing) Day conquered public parking spaces in German cities in September. The annual event aims to draw citizens’ attention to the relationship between living space for people and parking spaces.

Occupy parking spaces, create seating. In Melbourne, researchers at RMIT University have developed a non-commercial parklet. It bears the name “playful parklet”.

Projects and competitions

A special competition: the surroundings of Notre Dame are to be redesigned. Two years after the fire at the famous cathedral, the city of Paris launched a competition. Bureau Bas Smets from Brussels, together with other planning offices, won over the jury.

The Calder Gardens is an exciting project in the making. Herzog & de Meuro and Piet Oudolf are planning the gallery and garden for the works of artist Alexaner Calder.

Energy crisis: what is the status of renewables?

Also interesting: hydropower is valued as a renewable energy source. At the same time, there is also criticism of the consequences that hydropower plants entail. Find out more about the pros and cons here.

Good news in the face of the energy crisis: more solar power was produced in the EU this summer than in any summer before. 99.4 terawatt hours were produced between May and August 2022, according to calculations by the think tank Ember City Climate.

A little off the beaten track

With Build the Change, the LEGO company wants to get children excited about sustainable construction and urban planning. Find out more about LEGO’s sustainability initiatives here.

Italian designer Moreno Ratti wants to set an example against the waste of natural resources. That is why he uses natural stone waste to create new objects. His “Contrasti” series is made from recycled marble.

The bowls and vases in the “Contrasti” series each consist of two volumes: a rectangular block and a round element. The designer thus plays with opposing shapes – contrasts, as the Italian title translates.

One half of each object is finished; only the edges of the other are cut. In order to create a visual unity, the surfaces are treated uniformly.

Ratti cooperates with the Italian company Stonethica. The company recycles natural stone to produce new raw materials. These are slabs of marble slips from the Carrara region. According to the company, the elements are glued together with non-toxic resin.

Moreno Ratti explains: “The result of Stonethica’s ecological production cycle is the creation of a homogeneous material. The layered structure results from the combination and overlapping of stone slabs.”
