Review by Roman Schaurhofer, Vienna
Overview
The book "Building for the Community in Vienna" was published in 2021 by Isabella Marboe at Verlag Detail. All texts were printed in German and English in the book. In addition to an interview conducted by Marboe with Ulrike Schartner and Alexander Hagner, Robert Temel has his say in an expert article.
All in all, the book deals with 20 building projects in the Austrian capital Vienna and offers insight into the respective planning as well as the organisational and structural realisation of those very communities.
Content
At the beginning, Isabella Marboe looks back at historically relevant and significant events surrounding Viennese housing, community in everyday life and housing, and participatory building. The editor then highlights the importance and significance of the architect Ottokar Uhl and his work. Especially the projects "Living with Children" and "B.R.O.T." are mentioned and described as positive examples. In addition, Marboe goes into more detail about the historical developments surrounding the "Sargfabrik" and "MISS Sargfabrik" projects. Isabella Marboe is committed to a communal and socially solidary as well as responsible coexistence.
In Robert Temel's contribution, after a historical classification of Austrian pioneer and follow-up projects, there is also a brief description of organisational and ownership models. This is followed by an outline of the emergence of building communities and their possibilities for acquiring a building plot, as well as a comparison of several models implemented in Vienna.
In an interview, Ulrike Schartner and Alexander Hagner from gaupenraub+/- explained the many challenges that arise when creating quality housing for homeless people and at the same time show approaches to dealing with problems of this kind.
After the essays and the interview, there is a more detailed examination of the individual projects. A brief description, accompanied by key figures and background information, provides insights into the planning and implementation of the respective community ideas. In addition, illustrations and detailed plans (often in the form of floor plans) give the reader a better understanding of the structure and function of the respective project. In addition to individual buildings, row houses, multi-storey residential buildings and neighbourhood houses that stand out from their surroundings were also selected.
Criticism
The social and socially solidary approach of the project examples stands out in a clearly positive way. Each of the projects features people-oriented planning and high-quality implementation geared to the wishes of the residents, without losing sight of the demand for high-quality architecture. Although the communal and participatory character is clearly in the foreground as a unifying element, the individual projects cannot be denied their uniqueness and individuality in approach.
The detailed information, underpinned by pictorial representations, enables the reader to place the projects conceptually and contextually in their respective environment. With the overview and detailed descriptions of the sample projects, the editor Isabella Marboe offers a solid basis with carefully researched project examples for professional discourse and a more intensive examination of the topic of building communities.

The Federal Cabinet has adopted the Climate Protection Plan 2050 presented by Federal Environment Minister Barbara Hendricks (SPD) by circular resolution. It is based on the guiding principle of largely neutral greenhouse gas emissions by the middle of the century. For the year 2030, it confirms the overall target of a greenhouse gas reduction of at least 55 percent compared to 1990. At the same time, this overall target is broken down to individual sectors for the first time. The plan thus provides clear orientation for all sectors.

In future, three citizens' energy cooperatives will bear the award "Citizens' Energy Project 2017". A total of 17 projects nationwide took part in the competition for the title. The three winning projects received a particularly large number of votes during a two-month internet voting process, in which around a thousand interested people took part, and also prevailed in the evaluation of the jury consisting of committee representatives of the Bündnis Bürgerenergie (BBEn). The jury, consisting of five BBEn committee members, was impressed by the large number of applications to the competition, which was held for the first time, as well as the diversity of the applicant projects. According to the jury, the high level of the winning projects also shows how versatile the citizen energy companies in Germany currently are. This can be seen in the very different activities of the three winning cooperatives and the projects they submitted.
Development of a charging network According to the jury, the project of Inselwerke eG to set up an e-charging network on the Baltic Sea island of Usedom combines sustainable mobility and the expansion of the regional infrastructure so that "a strengthening of the important economic factor of tourism is achieved", as Thomas Banning, member of the jury and BBEn supervisory board member, emphasises. The professional concept of the cooperative convinced the jury and shows which business models are open to citizen energy companies. In particular, the possible duplicability of the charging network and the associated high reach of this approach are aspects that the jury considers worthy of an award. The Inselwerke eG developed a special Usedom model for a multi-stage expansion of the charging infrastructure for electric vehicles - not only on the Baltic Sea island, but also for the entire state of Mecklenburg-Vorpommern. Since April 2016, the cooperative has been able to set up 16 charging stations at 12 locations in cooperation with 11 partners, and more are currently being planned.
Noise barrier with integrated photovoltaic system The second winner, the EnergieGenossenschaft Inn-Salzach eG, is awarded for its noise barrier with integrated PV system. The energy cooperative in the Upper Bavarian region had erected a noise barrier together with the town of Neuötting. The 230-metre-long and almost five-metre-high structure along a busy road is also equipped with solar power panels. The modules together have a maximum output of 64 kilowatts, which can cover half of the electricity needs of a nearby school during the day. In addition, the wall also separates the school from traffic noise. In addition, the project flows into the lessons and thus ensures a tangible integration of the topic for the pupils.
According to the jury, this integrative concept reflects the current progress of the energy transition and uses dormant potential. Thomas Banning emphasises the recognisable double benefit of the solar noise barrier as follows: "The noise barrier combines the generation of clean energy with protection from the negative consequences of car traffic. The whole thing also has a high aesthetic value and is easy to communicate. That's how you move more!"
Innovative municipal energy concept The third winner, BürgerEnergiegenossenschaft Emmendingen eG, is awarded for its activities as a cooperative. According to Kai Hock, member of the jury and BBEn supervisory board member, it strives for a holistic energy transition from a technical point of view. It achieves a strong local impact with its activities, which can be seen, for example, in the number of 180 members. Thus, the cooperative has a high reach of the energy transition with its projects and achieves this with different forms of application and technologies, which is why a high innovative character can also be attributed to it.
For example, Emmendinger eG gave schools and residential buildings an all-round energy upgrade, consisting of heating systems, CHP systems and solar systems. It has also equipped buildings such as the adult education centre with photovoltaic systems on a lease model. In addition, a PV system on a goat shed with 250 kWp is currently being planned.
According to the jury, the three winners are particularly representative of the high level of activity of the many citizens' energy associations in Germany. They are therefore rightly awarded the title "Citizen Energy Project of the Year", on which the jury congratulates them warmly.
For more than 180 days, the electricity supply for the country's almost 5 million inhabitants has been provided almost entirely by renewable energy sources. Thanks to hydropower in particular, the country can now almost completely dispense with fossil fuels for its electricity supply. In addition to hydropower, wind power, photovoltaics and geothermal energy are also used.
