The Institute for Solar Energy Research (ISFH) has presented a free tool for the individual design and holistic evaluation of tenant electricity concepts.
These offer tenants in apartment blocks the opportunity to benefit from low-cost renewable electricity generated on site. However, profitability depends on many factors, which is why tenant electricity providers can hardly assess whether an investment is worthwhile without assistance. The new calculation tool is designed to solve this problem.
Programme based on Excel
The programme, which is implemented in Microsoft Excel, is based on a model that can be used to compare multivalent supply solutions. In addition to PV systems, small wind turbines and battery storage systems - previously excluded from tenant electricity subsidies - as well as combined heat and power supplies with combined heat and power plants, heat pumps or gas boilers can also be analysed.
The ecological assessment is based on the annual CO2 emissions avoided in the building, which is partly supplied with renewable energy, compared to a conventionally supplied reference building.

How can cities develop sustainably? How do they limit traffic, reduce pollutants and make attractive use of urban spaces, how do they create affordable attractive housing for all? These and other questions are at the centre of a project just launched by the Öko-Institut in cooperation with the Institute for Regional and Urban Development Research (ILS, Dortmund), the German Institute of Urban Affairs (difu, Berlin) and the City of Darmstadt, which has the working title "Transformative Strategies for Integrated Neighbourhood Development - TRASIQ".
Visions for the Future: Shaping Urban Neighborhoods Participatively and Sustainably
How can cities develop sustainably? How can they limit traffic, reduce pollution and make attractive use of urban space - in short, be liveable for their inhabitants? How can they meet the needs of an ageing population and the influx of younger people in equal measure, and how can they create affordable, attractive housing for all? What role do possible conflicts between ecology - more forest - and economy - more living space - play and how can they be resolved? These and other questions are at the centre of a project just launched by the Öko-Institut in cooperation with the Institute for Regional and Urban Development Research (ILS, Dortmund), the German Institute of Urban Affairs (difu, Berlin) and the City of Darmstadt, which has the working title "Transformative Strategies for Integrated Neighbourhood Development - TRASIQ".
In the two cities of Darmstadt and Griesheim, the project partners discuss sustainability requirements together with planners - for example with a view to limited budgets - and develop concepts and strategies for liveable neighbourhoods. How exactly such visionary ideas could be implemented is then to be co-developed by the future residents. team ewen and the Schader Foundation support the project in communicating and shaping the dialogue. The project is funded by the Federal Ministry of Education and Research.
Darmstadt and Griesheim - testing sustainable neighbourhoods
Darmstadt is one of the so-called "swarm cities" - that is, one of the 18 municipalities in Germany where the age group of 20 to 35-year-olds is concentrated far above average. The city has been growing continuously since 1997, currently at a rate of around 2,000 people per year. In this context, Darmstadt set itself targets for sustainable urban development early on and wants to test new settlement concepts in pilot projects such as on the site of the former Cambrai-Fritsch barracks.
"Precisely because we are a city of science, we rely on the dialogue between research and practice in urban development. We are particularly pleased to be cooperating with the Öko-Institut within the framework of TRASIQ, which is one of the most important players in the field of Green Smart City in Darmstadt's scientific landscape," explains Lord Mayor Jochen Partsch.
"Conflicts arise in the conception of an ecologically, socially and economically sustainable urban area - for example, in high-quality, energy-saving construction that nevertheless has to remain affordable," says Dr Dietlinde Quack, one of the two project leaders of the transdisciplinary project at the Öko-Institut, explaining the challenge. "Discussing such conflicts in the municipalities with those politically responsible, the citizens and future investors and finding a fair way for as many parties as possible is our task for the next three years. In doing so, the exchange about common visions of the future of design will help us. If all stakeholders agree on this, we can then align ideas for the concretisation of the development areas with it."

According to Dr Axel Berg, Chairman of the Executive Board of the German Section of EUROSOLARAccording to the author, neither ambitious climate protection goals nor an increased ecological awareness are the drivers of the energy turnaround, but rather "the exponential cost degression in renewable energy technologies, the technical innovations in storage technologies and a high level of interest from the industrial sector". In his detailed, expert contribution, he names three key technologies that, in their interaction, will accelerate the energy turnaround to such an extent that it is very likely that major players from German old industry, which for decades were considered the backbone of our powerful industrial nation, will be disrupted away by new players.
The three Key technology:
1. solar energies, especially photovoltaics and wind power
2. memory
3. renewable mobility
We would have to increase research and development efforts in Germany to tinker with new battery generations and all the high-tech. We need public showcases, the conversion of public authority vehicle fleets, showcase cities like Graz and the bundling of SMEs. In the SME sector, many new players with good ideas are waiting in the wings. Subsidies in the double-digit billions flow annually, only slowing down the wrong channels of old industry (e.g. diesel...).
Conclusion
According to Berg, citizens could look forward to the disruptive developments described. Our cities would become quieter, the air cleaner, the quality of life would increase. Mobility would become smoother and much cheaper [FNB: because only a fraction of the previous cars would be needed and the external costs would be eliminated].
It will be bitter for the old world. The car companies have a lot of money and can survive by shrinking - similar to what E.on or RWE are currently trying to do by splitting up. It will be brutal for the medium-sized suppliers who specialise in engine parts such as gearboxes, carburettors, clutches or pistons that are simply no longer needed. Or the 40,000 car repair shops in Germany alone, whose main job is to service combustion engines. The later they look for new fields of business, the harder the economic and social collapses will be.
Everything is ready for the start of information technology disruption: renewable energies, storage, digitalisation and autonomous electric vehicles. By 2030, all of this could already be accomplished.
