Model project: GBB PlusEnergy house in social housing in Bottrop
Published
The six 72-square-meter apartments of the GBB Plusenergiehaus on Südring are intended for tenants who have a certificate of eligibility for housing. Demand was high. Even before completion, all of the apartments, which were ready for occupancy from May 2015, were already occupied.
The fact that tenants in social housing can now also benefit from the PlusEnergy level and thus from low energy costs is another important step.

Council of Ministers approves bill to amend state building code
In its meeting on 26 May 2020, the Rhineland-Palatinate Council of Ministers approved in principle a draft bill to amend, among other things, the Rhineland-Palatinate Building Code. The amendment of the state building code is intended to implement changes to the so-called model building code that have already been adopted or are in preparation.
The amendments to the State Building Code relate in particular to facilitations for building with wood, which the construction ministers of the federal states agreed on at the last Construction Ministers' Conference, according to the official Press release. "I very much welcome the expansion of the possible applications for wood as a material. Wood is a particularly sustainable, environmentally friendly building material that plays an important role in achieving national and international climate protection goals. Moreover, wood is extremely versatile. Components can be produced for all areas of application, and there are particular advantages, for example, for serial construction as well as for conversion and extension measures. Last but not least, wood often enables cost-effective construction and promotes regional forestry, especially in Rhineland-Palatinate. In Rhineland-Palatinate there are many successful, exemplary projects in timber construction," explained Construction Minister Doris Ahnen.
With the amendment of the State Building Code, the use of timber components in taller buildings (especially multi-storey residential buildings) is now to be made possible under certain conditions. Accordingly, wood can be used as a building material for buildings up to a height of 22 metres; previously the limit was 13 metres.
The draft law now goes into the participation and consultation procedure.

The prize has been organised since 2005 by the Senator for the Environment, Building and Transport in cooperation with the Federal Chamber of Architects. Previously known as the Bremer Bauherrenpreis, the competition recognises the commitment of builders in Bremen and Bremerhaven. The aim is to showcase the range of services offered by housing construction in the state of Bremen and to provide impetus for future building projects.
The next award ceremony will take place in spring 2018.

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.
