As part of the BBSR study, 10 theses were developed for a "Garden City21 green-urban-networked" that describe process-related and functional qualities of sustainable and integrated urban development. These theses formed the basis for the in-depth investigation within the framework of the Future Lab. >> more information about the future lab
NATURSTROM is expanding its largest local heating project to date in Markt Erlbach, Franconia. In future, the eco-energy supplier will supply more than 130 customers with sustainable and locally generated heat - not only households but also municipal buildings and a large commercial enterprise. On 2,400 m2 Bavaria's largest solar thermal plant is being built for this purpose.
In the current second construction phase, NATURSTROM is connecting more than 70 new heat consumers, including the largest customer, the honey bottler Breitsamer & Ulrich GmbH & Co. KG. The company is providing the land for an energy centre and Bavaria's largest solar thermal plant with an area of 2,400 m2 available.
"The current turbulence on the European energy markets shows that we in Germany absolutely have to make ourselves less dependent on imports of fossil fuels," says NATURSTROM CEO Dr Tim Meyer. "With the heating turnaround towards decentralised renewable energies, we are not only doing the climate a great favour, but also ourselves and our economy. The local heating supply in Markt Erlbach is a great example of how the changeover can succeed."
Since 2019, NATURSTROM has been supplying 40 consumers with ecological heat at long-term stable prices via a wood pellet heating centre. After completion of the second construction phase, the local heating network will be 6.4 kilometres long. In addition to numerous private households and the Breitsamer company, the heat consumers also include smaller businesses and municipal buildings such as the school, the indoor swimming pool and an event hall. "We are pleased that so many and such different players in Markt Erlbach want to be part of the local heat turnaround," says Meyer.
After connecting all consumers, the total heat demand in the network is around 5,350 megawatt hours (MWh) per year; by covering this demand from renewable sources, approx. 1,800 tonnes of CO2 saved. In addition to solar heat, NATURSTROM uses wood pellets from the region as fuel in the existing energy centre, and regional wood in the form of wood chips will also be used in the second energy centre once the second construction phase is completed. "With the raw material supply from the region, we can provide affordable and sustainable energy for our citizens in the long term. Especially for future generations, it is important to act decisively for climate protection," emphasises Markt Erlbach's First Mayor Dr Birgit Kreß.
The two energy centres and the local heating network are designed to be open to new technologies, so that modernisation and expansion to supply new consumers are possible.
The impetus for planning the local heating supply came from a renovation of the main street. The connection to the local heating network will mainly replace old, climate-damaging oil heating systems. Particularly due to the lack of gas supply infrastructure, more than 80 percent of the inhabitants in Markt Erlbach still used heating oil before the start of the first construction phase.
Isabella Marboe (ed.) Bauen für die Gemeinschaft in Wien Neue gemeinschaftliche Formen des Zusammenlebens. Edition Detail 2021, 144 pages, de/eng, Euro 39.90
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.

State aid for housing construction drives up prices, but does not bring more housing. This is how an assessment by the DIW (German Institute for Economic Research), Berlin, can be interpreted.
Unanimously, on March 21, 2019, members of Berlin's state parliament voted in favor of promoting urban timber construction.
Following in the footsteps of Baden-Württemberg, the state of Berlin has now also decided to focus on wooden buildings in the future with its application "Sustainability in construction: Berlin builds with wood". As part of the Berlin Energy and Climate Protection Programme (BEK), wood as a building material is to be used to a much greater extent from now on and, as a carbon dioxide reservoir, is to make a contribution to climate protection and resource efficiency.
As the largest builder in the city-state, the Berlin Senate is to lead the way in the future and increasingly use wood in state buildings such as schools, kindergartens and residential buildings. In addition, subsidy programs such as those in Baden-Württemberg, Hamburg and Munich should create incentives for private builders. A timber construction cluster is to develop and bundle competencies along the value chain in the long term.
Since April 2018, an amendment to Berlin's state building code has facilitated timber construction for private and public buildings. Load-bearing components of multi-storey buildings can now be made of the natural material without the need for a time-consuming case-by-case assessment.
For new buildings and complete modernisation projects, Berlin will in future apply the Sustainable Building Rating System (NBB) with its defined, transparent standards for sustainability.
