The construction sector is one of the biggest consumers of resources in Germany. With the "Seeviertel" new housing development, the municipality of Inden in the Rhenish lignite mining region, together with RWE Power, the Aachen-based Kathy Beys Foundation and the development company indeland GmbH, has set itself the goal of halving resource consumption. As the first settlement of its kind in Germany, the Seeviertel demonstrates how energy efficiency and resource conservation can be integrated into neighbourhood development right from the ground-breaking ceremony.
5th Symposium on Citizen Energy & Energy Cooperatives in NRW

Recklinghausen. Energy in the hands of citizens: This was the topic of the specialist conference on citizen energy & energy cooperatives in North Rhine-Westphalia on Thursday, 6 December, in Recklinghausen. Around 80 stakeholders in community energy met there to exchange experiences and transfer knowledge. The 5th symposium is a cooperation of the Cooperative Association - Association of Regions and the EnergyAgency.NRW.
Marlies Diephaus from the Ministry for Economic Affairs, Innovation, Digitalisation and Energy of the State of North Rhine-Westphalia kicked off the conference by emphasising the importance of citizen energy companies: "The energy transition is a major challenge that must be shaped in a positive and forward-looking way here in North Rhine-Westphalia. To this end, a reliable framework must be created in which all stakeholders and affected parties can find their place. Last but not least, the financial participation of citizens in various forms also plays a central role. It can contribute to the acceptance of this project of the century.
In the Raiffeisen Year 2018 - the anniversary year of the cooperative idea - around 20 million people in Germany are members of a cooperative. In the field of citizen energy, too, more and more people are discovering this form of joint economic activity. "The global energy turnaround is only possible at all through local action. Here, citizens, organised in citizen energy societies, are both drivers and advocates. This is where co-determination and regional participation happen locally," explained Dr Frank-Michael Baumann, Managing Director of EnergyAgency.NRW.
Dominik Kitzinger, Division Manager at the Association of Cooperatives - Verband der Regionen e. V., emphasised: "In North Rhine-Westphalia, around 100 energy cooperatives are active as operators of generation capacities - from photovoltaic to wind energy plants - as well as around 150 citizen energy companies of other legal forms. Nationwide, more than 41 percent of investments in renewable energy come from civic engagement. If Germany wants to meet its climate targets, it can only do so with this local commitment."
In addition to projects from the areas of photovoltaics, local heating and wind, the focus was also on the mobility transition. Here, the participants agreed that e-mobility must go hand in hand with the energy transition. Citizen energy companies and cooperatives must therefore be strengthened through cooperation and transformation. Cooperatives that already market car sharing, the operation of charging infrastructures and jointly produced electricity were presented as best-practice examples. There are around 40 energy cooperatives active in these areas throughout NRW.
Despite the growing interest in cooperative management, the number of new energy cooperatives founded has declined in recent years. René Groß from the German Cooperative and Raiffeisen Association blames the changed legal framework conditions for this, but also the complex demands on the mostly voluntarily organised civil societies. In this context, the conference participants also debated the controversial effects of legislation at national and European level, such as through the Energy Collection Act and the new EU Directive as well as the Renewable Energies Directive.
On 14 December 2016, the North Rhine-Westphalia state parliament passed the amendment to the state building code. The main parts of the new version will come into force one year after publication in the NRW Ministerial Gazette, i.e. in all probability at the beginning of 2018.

A further 700,000 euros will be available for #moinzukunft cargo bikes from 1 April. Up to 2,000 euros in subsidies are possible for the purchase of a new e-load bike and 500 euros for normal load bikes.
BN - Is the roof of my house or company building suitable for a photovoltaic system or a solar thermal system? This question can now be answered quickly and conveniently online with the help of the new solar roof cadastre of the city of Bonn. In a building-specific map display, a coloured marker indicates whether and to what extent a roof is suitable for energy generation by means of solar power. Step by step, further information, for example on the economic efficiency, can be retrieved via a yield calculator.
The suitability of the roofs of all 129,000 buildings in the city for solar energy generation was recalculated using the latest, improved data. For this purpose, elevation grid data was used, which was determined by the district government of Cologne by means of laser scanning in spring 2016. Compared to the previous version from 2010, the new Bonn solar roof cadastre features, among other things, a fourfold higher resolution and a more differentiated designation of the roof areas.
The suitability of the roof surfaces for electricity generation via photovoltaic systems as well as for domestic water heating and, for the first time, also for supporting building heating via solar thermal collectors was calculated. The calculations also took into account the current changes in the framework conditions with regard to feed-in tariffs and self-consumption of generated solar power.
How the application works
In the city map, the installable system size and many additional data such as yields and savings potentials can be displayed for each building. In a newly developed yield calculator, costs and yields can be calculated and compared by entering additional user-specific information such as electricity consumption or household size. In this way, every owner can quickly gain an overview of the suitability of his or her building for the use of solar energy. Detailed instructions are available at www.bonn.de/...solardachkataster.php.
The City of Bonn points out that the information from the solar roof cadastre is an initial non-binding assessment. Essential prerequisites for a decision to build a system, such as the condition of the roof or the static suitability, can only be clarified by suitable specialist companies or qualified consulting organisations. Information on this can be found on the website of the solar roof register.
Bonn roofs have potential
According to the potential analysis of the solar roof cadastre, 6,800,000 square metres in Bonn are suitable for solar power generation. This corresponds to about the size of 950 football fields. Approximately 800,000 megawatt hours of electricity could be generated on this area. This could cover about 50 percent of the total electricity consumption in Bonn. For solar thermal energy, the result of the potential analysis shows 88,461 buildings in Bonn that could be used for this form of energy generation. This corresponds to about 70 percent of the buildings in Bonn.
