In Troisdorf, North Rhine-Westphalia, the largest tenant electricity project in Germany is currently running with subsidised funding from the so-called tenant electricity surcharge under the Renewable Energy Sources Act (EEG). The project, which was supported by EnergyAgency.NRW following an initial consultation, supplies 24 social housing apartments in three multi-storey buildings with a total of 75 residents with electricity. For this purpose, all roof surfaces were covered with photovoltaic modules with a total output of 86.9 kWp. The PV system is completed by six Powerwall 2 battery storage units from Tesla. "The tenants have committed 100 per cent to the project. In addition, the PV electricity, insofar as it is not consumed by the water-to-water heat pump or the tenants, is first stored in electricity storage units. This works so efficiently that we already reached an average self-sufficiency level of 83 percent in May. On isolated days and nights, even 98 percent," explains Frank Scholzen from Scholzen Immobilien, the company that owns the properties.
In rental electricity projects, electricity is generated in a rented property - by PV and/or combined heat and power (CHP) units. This direct electricity is often sold by the operator of the plant to the local energy supplier or - as in Troisdorf - by the landlord to the tenants. "The electricity offered to the tenants is cheaper than electricity from the grid. The advantage for the system operator is an additional income opportunity, as well as an ecologically sustainable electricity supply," explains Wilhelm Schröder from EnergyAgency.NRW, who accompanied the project in an advisory capacity.
However, the three buildings of Scholzen Immobilien are not only characterised by an innovative power supply, Troisdorf is also future-proof in the area of heat: The heating system consists of two water-water heat pumps with a combined thermal output of 76 kW. The well depth is only 14 metres - thanks to the high groundwater level not far from the Rhine. Scholzen: "The smart meters supplied by the Aachen-based company Discovergy enable continuous monitoring of the energy flows between the PV system, heat pump, energy storage and main meter."
In this complex and demanding project, many parties have to be coordinated. In Troisdorf, the following were involved:
In the meantime, the company Scholzen Immobilien is planning another tenant power project in Düsseldorf.
By the end of April 2018, a total of 19 tenant power projects subsidised under the EEG with an installed capacity of more than 350 kWp had been realised in NRW. The EnergyAgency.NRW has published a brochure entitled "Mieterstrom - kurz erklärt" (Tenant Electricity - Explained in Brief), which presents in detail the technical and legal aspects that need to be considered when implementing projects.

What makes a sustainable university? Sustainability Council and 50 university administrations, employees and students are developing a sustainability code for universities. The test phase of the beta version of the university code will start in autumn. In autumn 2014, the German Council for Sustainable Development (RNE) held a stakeholder conference on "From Pilot to Standard: Implementing Sustainability in Research, Teaching and Operations" to discuss the implications [...]

For the fifth time and in keeping with its 120th birthday, Spar- und Bauverein Solingen eG awarded the nationwide Klaus Novy Prize for innovations in cooperative building and living in July. This prize was established by SBV eG as a stimulus for cooperative ideas on the occasion of its 100th anniversary. This year, the prize was awarded to projects that "socially and innovatively" strengthen membership in a cooperative and coexistence in neighborhoods.
"From children's cooperatives to housing projects for refugees: housing cooperatives today are more colourful, dynamic, open-minded and sustainable - innovative and social." SBV Board Chairman Ulrich Bimberg was enthusiastic about the "exciting exchange of knowledge" that took place in the cooperative's own historic washhouse Weegerhof.
Michael Groschek, Chairman of the NRW SPD and former Minister of State, was impressed by the award's namesake: Professor Klaus Novy had imagined the ideal society as a cooperative. The housing market in Germany is a long way from that, he said. "Unless you are lucky enough to live in Solingen, where every tenth apartment is cooperative." During his visit, Michael Groschek paid tribute to the innovative cooperative projects - as former NRW Minister for Construction, he has a special connection to the subject.
Eight cooperatives from all over Germany presented their ideas to the expert audience after a pre-selection from 31 submitted entries. In the end, the new Zurich housing cooperative "Mehr als Wohnen eG" prevailed in the democratic selection process. Their forward-looking and sustainable project was convincing from a social, technical and ecological point of view and received 4000 euros. Second place and 2000 euros went to "Inklusiv Wohnen Köln e.V.", the house project of an association of parents with disabled children. "Bellevue di Monaco eG" from Munich, a housing and social cooperative for refugees, was pleased with third place and 1000 euros. There were no losers in the innovative performances, but a win for all. SBV Chairman Ulrich Bimberg: "Every participating cooperative has something very special." For co-organiser Arno Mersmann, what is typical of a cooperative is: "What one person can't achieve alone, one can achieve together.
Laureate 2017
Klaus Novy Prize
The prize is dedicated to Prof. Klaus Novy (Professor of Building Economics, born 1944 in Vienna; died 1991 in Seattle, USA), who championed the renewal of cooperative housing culture. To mark its centenary in 1997, Spar- und Bauverein Solingen eG launched the nationwide competition. Every five years, current innovations are honored - also as an inspiration for others. Competition theme 2017: "Innovative social cooperative". Contact: Arno Mersmann, telephone 0202/563 20 58, e-mail: amersmann@hotmail.com
