The Saxony-Anhalt Ministry of the Environment has announced a subsidy program for electricity storage for photovoltaic roof systems. Private individuals, companies and tenant electricity models will be reimbursed 30 percent of the expenses.
Good news for the PV industry: The solar cap will be abolished and solar expansion will be further promoted. The photovoltaic potential in Germany is enormous - especially when it comes to using roof space on new buildings. The new LichtBlick SolarCheck now shows in detail how well the 14 largest German cities are currently exploiting this potential. Enormous differences are revealed: While Nuremberg (49.1%) and Hanover (46.8%) exploit almost half of their potential, Munich and Düsseldorf do not even reach the 10 percent hurdle. The absolute taillight: the Hanseatic city of Hamburg with only 7.2 percent - one more reason for the solar obligation for new buildings planned by the mayor's office.
To calculate the solar potential of the individual cities, the newly built roof areas were put in relation to the newly installed photovoltaic systems in the respective cities in 2018 (most recent figures). The result: the PV potential on roofs is barely exploited in most metropolitan regions in Germany. Yet every new roof without a solar installation is a wasted opportunity for climate protection and a consumer-oriented power supply. The vast majority of people in Germany want solar power from their roofs*.1
In view of the sobering results of the SolarCheck, Ralph Kampwirth, Head of Corporate Communications at LichtBlick, said: "We must finally bring the energy turnaround to the big cities - and the best way to do that is with solar power from the roof. Discussions about distance regulations for wind power or the use of agricultural land for PV plants show that the responsibility should not only lie with the rural population."
Converted to German households (average consumption 3,000 kWh), the possibilities of the individual cities become apparent: If Munich had fully exploited the potential of the new building roof areas, you could have supplied more than 10,000 households with solar power with the new solar areas built in 2018 alone, Hamburg around 11,500 households, in Berlin it would be 16,200 households." Especially in the megacities, only a small fraction of this is developed, as the SolarCheck shows.
About the research method: The market research company Statista determined the number of newly constructed residential and commercial buildings in 2018 for the 14 German cities with more than 500,000 inhabitants on the basis of data from the State Offices for Statistics and calculated the respective roof areas using scientifically based conversion factors.

The Rosenstein urban planning competition recently ended with the decision on the winning design. First place went to the Stuttgart-based asp Architekten/Koeber Landschaftsarchitektur consortium. Detlef Kron, Head of the Office for Urban Planning and Housing, opened the exhibition on the Rosenstein competition in the Church of St. Maria at Tübinger Straße 36 in Stuttgart on Friday, 27 September, at 5 pm.
At the opening event, Kron said: "The Rosenstein urban planning competition was a complete success: with over 50 submissions from international planning offices, the city of Stuttgart has received a wide range of design ideas for the future Rosenstein quarter. So that the people of Stuttgart can now also get a picture of them, we will be exhibiting the results in the Church of St. Maria over the next four weeks."
The Office of Urban Planning and Housing is displaying all the submitted works from the competition in the exhibition. In addition to plans, drawings, and information about each submitted proposal, revised first and second place models will also be on display. The exhibition will be open for viewing daily (except October 3) between 10am and 6pm until October 25, 2019. Admission to the exhibition is free of charge.
Since 2017, the parish of St. Maria in the south of Stuttgart has made its church available for events other than church services. Whether theatre, café, gallery or marketplace - for two years now, the church of St. Maria has been tested as a space for togetherness with the implementation of various event formats.
In summer 2018, the city of Stuttgart announced the "international open urban planning competition Rosenstein - Ideas for the new district". The aim of the planning competition was to obtain an urban and open space planning design as a model for the future development of the Rosenstein district. A total of 54 international planning offices took part. Beforehand, citizens were able to contribute their own wishes and ideas for the Rosenstein Quarter at various information events and workshops held by the City of Stuttgart. These were incorporated into the competition.
The Rosenstein development area is currently considered the largest construction project to be realized in Stuttgart in the near future. It stretches between the main railway station, Nordbahnhofviertel, Rosensteinpark and Schlossgarten and offers 85 hectares of space for future-oriented living and working in the heart of the city. The Rosenstein Quarter is to be developed into an urban and mixed district with a high diversity of uses, attractive public spaces and internationally renowned cultural offerings. In addition, the quarter is to be developed under climate-friendly aspects. In addition to the expansion of the parks, the guiding principle of the energy-plus quarter plays a major role: the future buildings should generate more energy than they consume.
Currently, the designs of the winning office asp Architekten/Koeber Landschaftsarchitektur are also on display at the Info-Laden Rosenstein auf der Prag e.V.. The exhibition in the Gläsernes Büro at Nordbahnhofstraße 81 can be seen until October 12, always on Mondays and Wednesdays between 5 and 7 p.m., Saturdays from 10 a.m. to 12 p.m. and by appointment.

In the current publication, the wohnbund takes a look at the development of new urban quarters. Backwards - with the question of what became of the goals that were set for individual projects. To the present day - to the concepts that are being implemented in response to current challenges. It writes in more detail about at least ten new housing estates and neighbourhoods, five of which (Freiburg Vauban, which French Quarter, Hanover Kronsberg, Ackermannbogen Munich and the Heidelberg Railway City) are listed in the sdg21.web database.

Since the first edition of the FNR brochure "Straw Insulated Buildings" in 2013, building with this environmentally friendly and cost-effective material has developed positively.
Since 2014, it has been possible to plaster the bales directly on the inside and outside of buildings without additional plaster base, as well as to insulate the outside of masonry. Straw now also offers an interesting option for the energy-efficient refurbishment of old buildings.
The new edition of the FNR straw building brochure therefore contains a completely new chapter on the topic of "Renovation concepts with straw". It also provides good arguments for building sustainably with straw and updated cost overviews. Some of the building examples presented are also new, including three-storey, directly rendered straw buildings.
