The Ecological model settlement in Prinz Eugen Park in Munich, currently the largest contiguous timber housing estate in Europe, was presented.
The Holzbaunetzwerk München organized a guided tour through the ecological model settlement in Prinz Eugen Park in Munich on 24.05.2019. In 2009, on the initiative of the Green Party, the City Council of the City of Munich decided to build an ecological model settlement with 600 apartments in timber construction in the new district on the site of the former Prinz Eugen barracks in Bogenhausen. Based on the urban design by GSP Architects with Rainer Schmidt Landscape Architects, eight developers, the municipal housing associations GEWOFAG and GWG München, building communities and building cooperatives have developed timber construction projects ranging from atrium houses to seven-storey residential buildings. Today, all projects are under construction and some will be completed this year.
The Holzbaunetzwerk München could welcome about 400 guests. The architects of the model settlement presented their projects to interested visitors, builders, urban planners, timber construction companies, architects, investors and citizens in two parallel guided tours on 24.05.2019 in the course of a tour through the quarter. The various timber construction methods, from pure timber construction to hybrid construction methods with reinforced concrete staircases to reinforced concrete skeleton construction with timber facades, were vividly explained using the projects.
Presented were the projects of the building cooperative WOGENO with the Quartierszentrale by Mr. Florian Lünstedt from the office Atelier 5 Architekten Bern, the GEWOFAG by Jakub Pakula and Eduard Fischer, Pakula & Fischer Architekten Stuttgart, the GWG München by Stefan Rapp, Rapp Architekten Ulm, the building community Team3 by Architekturwerkstatt Vallentin München Dorfen, the building community München GbR by Sibylle Hüther, H2R and PlanZ Architekten from Munich, the Baugemeinschaft Gemeinsam Größer II by Markus Borst, agmm Architekten+Stadtplaner Munich with Hable Architekten, the Baugenossenschaft Bürgerbauverein München eG by Markus Lager, Kaden + Lager Architekten Berlin and the Baugemeinschaft Der kleine Prinz by Ulf Rössler, dressler mayerhofer rössler architekten und stadtplaner GmbH Munich.
Afterwards, at 6 p.m., a panel discussion with the city councillors Ms. Heide Rieke (SPD), Mr. Herbert Danner (Die Grünen), Ms. Ulrike Klar, (City Director, Department of Urban Planning of the City of Munich) and Ms. Gerda Peter (Managing Director of GWG Munich) on the future of timber construction in Munich rounded off the event. It was discussed how the path taken can become a model for further new building areas, what lessons can be learned from the Ecological Model Settlement and how a promotion of timber construction can be designed for the future planning areas of the Bayerkaserne, the urban extensions in the east and north and the redevelopment area of Neuperlach. To this end, the Holzbaunetzwerk München wants to launch the Holzbaustadt München 2030 initiative with at least 2030 residential units in timber construction. How it works could be seen in the Prinz Eugenpark on 24.05.2019.
The Holzbaunetzwerk München was founded in 2018 by Andreas Lerge (Wood Real Estate GmbH) Thomas Kapfer Architekt and Ulf Rössler Architekt (dressler mayerhofer rössler architekten und stadtplaner GmbH). The Holzbaunetzwerk wants to work to connect the stakeholders from politics, administration, planning and business, to engage in the further promotion of timber construction in Munich and to initiate the vision of the timber construction city Munich 2030.

The passive house turns 30 - pioneering work paves the way for energy efficiency worldwide
The passive house celebrates its 30th birthday! The pioneering project of building physicist Prof. Wolfgang Feist, which started as an experiment, can take great credit: When climate protection was only on the agenda of very few, it paved the way for energy efficiency in buildings. Today, the Passive House Standard is being implemented around the globe, including in impressive lighthouse projects. Other reasons to celebrate: the 25th anniversary of the Passive House Institute and the anniversary edition of the International Passive House Conference.
"I am of course happy about this development: from the first experimental residential building to the worldwide projects and quarters in the Passive House Standard," explains Passive House pioneer Prof. Wolfgang Feist. However, he makes it clear: "Without a much greater commitment from governments, however, progress in the better energy design of buildings will be slow." Yet the physicist has demonstrated a viable solution for high energy efficiency with the construction of the world's first passive house.
Priority Climate protection
It was already clear in the 1970s, says Feist in the interview, that fossil energy resources are limited. In addition, the extraction and use of this energy caused excessively high CO₂ emissions. Together with the Swedish engineer Bo Adamson, he searched for solutions that would allow houses without conventional heating systems to be built in the Central European climate. The biggest motivation: climate protection.
Stop heat loss
One thing was clear: the typical but unnecessary heat loss in buildings must be greatly reduced. Among other things, through good thermal insulation on the walls, the roof and the ground. And an additional, third pane in the windows. If the building is also built to be almost airtight and thermal bridges are avoided, then the interior rooms will automatically remain pleasantly warm for a long time with the support of passive heat sources such as solar radiation. In summer, passive houses are pleasantly cool.
Smiled at by many
Finally, Prof. Wolfgang Feist determined characteristic values for better building: This is how the Passive House Standard came into being. Feist determined that this should be freely available to all interested parties. The Feist family built the pilot project "Passive House" in a community with three other families, as a complex of four identical terraced houses. The state of Hesse supported the research project. Nevertheless, it was smiled at by many.
Research since day 1
On a site that the city of Darmstadt had designated for "experimental building", the excavators rolled in in autumn 1990. In the spring of 1991, exactly 30 years ago, the building families celebrated the topping-out ceremony together with the public. And in autumn 1991 they moved into their new home. Since day one, intensive research has been carried out on the world's first passive house; among other things, a measurement project of the International Energy Agency (IEA) is currently underway.
Social justice
30 years after the first passive house was built, schools, daycare centres, gymnasiums, supermarkets, indoor swimming pools, museums, hotels and entire neighbourhoods are now built to the passive house standard as a matter of course. Today it is well known that Passive Houses require very little energy for heating and cooling. This makes them an important building block for effective climate protection. And for social justice. The high living comfort is a big plus. Increasingly, municipalities and states are stipulating consistent energy efficiency in the Passive House Standard in their building regulations. (Passive House resolutions).
Energy efficiency a must
In view of the climate crisis, it is clear that energy-efficient construction is needed. The Federal Constitutional Court in Karlsruhe has just declared the German Climate Protection Act unconstitutional in parts: the government must regulate more clearly how emissions are to be effectively reduced after 2030, according to the ruling.
approach tipping points
Energy-efficient buildings are fundamental to a widespread renewable energy supply and therefore an important part of the solution. "When tipping points are reached, there is no vaccine to stop the horror. We must act now to keep the future on this planet livable. The building sector must do more to mitigate climate change. Many national building standards still allow too much energy consumption," warns Feist.
25 years of the Passive House Institute
Manufacturers and tradesmen have also grasped the potential of energy-efficient construction and renovation as an opportunity. The Passive House Institute's component database now counts over 1200 certified components. The Technical University of Innsbruck recognised its importance for research and teaching at an early stage: Building physicist Wolfgang Feist taught energy-efficient construction there for over ten years. As a result, the number of experts is also growing. Every year many of them meet at the International Passive House Conference. This is also an anniversary, taking place for the 25th time this year. Shortly before the first conference in 1996 Wolfgang Feist had founded the Passive House Institute. That celebrates now its 25-year old existence. Another reason to celebrate.
Passive houses
The passive house concept drastically reduces the heat loss through walls, windows and roof that is typical for buildings. Thanks to the five principles - good insulation, triple-glazed windows, avoidance of thermal bridges, an airtight building envelope and a ventilation system with heat recovery - a passive house requires very little energy. Passive houses can therefore do without a classic heating system. The houses are called "passive" because most of the heat requirement is covered by "passive" sources such as solar radiation and waste heat from people and technical equipment.
In a passive house, the heat is retained for a very long time because it escapes only very slowly. Therefore, active heating is only required on very cold days. Overall, only little energy is needed to provide this residual heat. In summer (as well as in warm climates), a passive house also has an advantage: then, among other things, the good insulation keeps the heat out. Active cooling is therefore not usually necessary in residential buildings. Due to the low energy costs, the ancillary costs are calculable - a basis for affordable living and social housing. A passive house consumes around 90 percent less heating than an existing building and 75 percent less than an average new building.
Passive House and NZEB
The Passive House Standard meets the European Union's requirements for Nearly Zero Energy Buildings. According to the European Buildings Directive EPBD, member states must specify the requirements for so-called Nearly Zero Energy Buildings (NZEB) in their national building regulations. The EU directive has been in force for public and private buildings since January 2021.
Pioneering project
The world's first passive house was built more than 28 years ago in Darmstadt-Kranichstein by four private builders, including Dr. Wolfgang Feist. Since the families moved in in 1991, the terraced houses have been regarded as a pioneering project for the passive house standard. The pioneer passive house now uses renewable energy with its new photovoltaic system and was awarded the Passive House Plus certificate.
Passive house and renewable energy
The passive house standard can be combined well with the generation of renewable energy directly on the building. Since April 2015, the new building classes "Plus" and "Premium" have been available for this supply concept.
Passive House Institute
The Passive House Institute, based in Darmstadt, is an independent research institute for the highly efficient use of energy in buildings. Founded by Wolfgang Feist, the institute occupies a leading international position in research and development on energy-efficient construction. Prof. Wolfgang Feist received, among others, the DBU Environmental Prize in 2001 for the development of the passive house concept.

The bioeconomy can be a central building block for the transformation of our largely coal, oil and gas-based economy. However, renewable raw materials and synthetic carbon compounds are scarce and expensive. They should be used in areas such as the chemical industry - not as energy sources. For the shift from a fossil-based economy to a bioeconomy to succeed, fossil carbon must also become more expensive. The ifeu now presents the results of four trend-setting studies.
"Carbon compounds will continue to be needed in the chemical industry and, in the medium term, in parts of the transport sector. Here we can use biomass and other renewable carbon sources for chemicals, bio-based products or fuels, replacing fossil carbon in the form of oil and gas," says ifeu project manager Dr Heiko Keller. "Bioeconomy provides much more than fuels from agricultural biomass," adds Nils Rettenmaier, also project manager and expert on
Biomass and Bioeconomy at ifeu. However, the resources of the bioeconomy are a scarce commodity. Cultivation areas for renewable raw materials are limited by food production and the protection of biodiversity.
Such cultivated biomass can no more cover the long-term demand for carbon than can biogenic residues. Defossilisation of the economy needs framework conditions. In order to build a stable market, the bioeconomy would need fair competitive conditions in which its advantages over products made from
fossil CO2 sources are taken into account, according to the experts. Thus, in the long term, products from biogenic raw materials can prevail over the hitherto cheaper fossil raw materials through a higher CO2 tax. In addition, sufficient green electricity and hydrogen must be available in the medium term.
"If the right course is set, the bioeconomy can make a significant contribution to defossilisation," says Rettenmaier. "It is an important piece of the puzzle in the transformation towards a climate-friendly society.
For large parts of the economy, ways to say goodbye to fossil fuels are now foreseeable - for example with electric cars and heat pumps instead of combustion engines and gas heating. But a complete decarbonisation of the economic system is neither possible nor sensible. Therefore, ifeu is researching technologies that make sustainable renewable carbon available. The reports from four recently completed large-scale projects provide valuable new insights.
(Re)activating arable land that is hardly usable for other purposes
In the EU, there is a lot of unused arable land and some special sites such as post-mining areas. With the cultivation of frugal biomass on these so-called marginal areas, the increasing competition for land use can be mitigated. In the MAGIC project, ifeu has identified boundary conditions that must be met for sustainable implementation:
- Care must be taken not to endanger biodiversity, which can be high on parts of these areas, through use.
- Imposing conditions on subsidies that are necessary anyway can be a solution to this conflict of goals.
Detailed recommendations can be found in the report on MAGIC at

Converting biomass residues into products needed in the long term
Many residual materials such as straw or green waste from landscape conservation (so-called lignocellulosic residues) are not used to a large extent. Others, such as forest residues, are currently burned primarily for energy use. However, heat can and should be generated in the medium term, for example via heat pumps using green electricity. The scarce renewable carbon is too precious for these decarbonisable applications. New technologies are now being developed so that these residues can be efficiently converted into products such as chemicals or aviation fuel in the future.
The UNRAVEL project investigated how new processes and value chains for chemicals and building materials (insulating foam boards, bitumen sealing membranes, etc.) can be established. From a sustainability point of view, decisive progress was made:
- The process can now flexibly use different residual materials at constant product quality - depending on sustainable availability.
- The energy efficiency of the main process (organosolv) was significantly increased.
- A technical bottleneck has been identified that has so far been responsible for the fact that residual materials that are currently hardly used in particular can be converted less efficiently.
Concrete further steps on how the process could be further developed in a future-proof manner, both from a raw material and product perspective, are listed in the reports (link: https://www.ifeu.de/projekt/unravel).
Lignocellulosic residues can also serve as a feedstock for bio-oil by means of pyrolysis. A process developed in the BioMates project uses green hydrogen to prepare the bio-oil for easy feed into petroleum refineries. Partial replacement of petroleum in refineries with bio-oil can reduce greenhouse gas emissions in the relatively short term. This is urgently needed from a sustainability perspective. In the long term, the share of refinery products for chemicals, aviation and marine fuels in particular could be expanded. The sustainability assessment is available at https://www.ifeu.de/projekt/biomates available.
Synthetic hydrocarbons
In the eForFuel project, it was not biomass that was investigated as a carbon source, but the synthesis of hydrocarbons from CO2 from industrial point sources (here: blast furnace gas) as well as the air. This can be converted to formic acid in an electro-biorefinery using renewable electricity and water and fermented in a bioreactor with the help of microorganisms. The end products are synthetic fuels such as propane and isooctane. Main findings from this project:
- Renewable carbon can be obtained in far greater quantities if it comes from CO2 instead of plant biomass. However, even in this case, efficient use is crucial, because harnessing it requires a great deal of energy.
- Many improvement options could be identified. However, some development work is still needed before it is ready for the market.
