Permanently cheaper: 100% Renewable Energies in Europe
Published
A recent study by the Energy Watch Group and the Finnish University LUT shows how the energy transition can be realised with 100% renewable energies in Europe. According to the study, greenhouse gas emissions would be reduced to zero before 2050 and there would be significant financial advantages compared to the conventional fossil-nuclear system.
The balcony modules with which EWE has equipped an entire apartment building in Delmenhorst have been in operation for a year. The yield balance shows that tenants use almost 80 per cent of the solar electricity themselves and can cover up to 20 per cent of their electricity consumption with it.
The German Federal Ministry for Economic Affairs and Energy (BMWi) is expanding its funding for fuel cell heating systems. With immediate effect, you can apply to KfW for attractive subsidies for the installation of fuel cell heating systems in both all residential and non-residential buildings. Private individuals, freelancers, small and medium-sized enterprises (including contractors) as well as municipal and non-profit organisations are eligible to apply.
The subsidy is available for fuel cell heating systems with an electrical output of up to 5 kW that are installed either as part of a refurbishment or a new build. Depending on the electrical output, a subsidy of up to 28,200 euros per installed fuel cell is possible.
The aim of extending the funding is to establish the pioneering fuel cell technology for supplying electricity and heat in buildings on a broad market. Fuel cell heating systems are significantly more efficient than conventional combined heat and power systems. The natural gas or biogas used is utilised much more efficiently, which also leads to lower CO2 emissions.
Grant funding for fuel cell heating systems is part of the German government's "Energy Efficiency Incentive Programme". It supplements the existing KfW programmes for energy-efficient construction and renovation. Since the programme was launched in August 2016, the installation of over 900 fuel cell heating systems, primarily in detached and semi-detached houses, has been supported with grants of around 13 million euros.

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.
