Production in the city is not a new phenomenon. Urban production - in its various forms and development paths - is one of the constitutive features of a city. The concept of the Productive City opens up the possibility of using a strategic approach to link the central aspects of the changing socio-economic basis of cities (development of new forms of production and work) with the goals of a compact and functionally mixed city.
In a research project of the iaw, the conceptual foundations of urban production and the productive city were prepared with a view to the situation in Bremen and analysed in their impact structure. The study makes proposals for describing and recording urban production that is compatible with the city and embedding it in an urban development policy model of a productive city. On the basis of seven reference cities (Vienna, Zurich, Stuttgart, Hamburg, Frankfurt am Main, Wuppertal, Bochum), corresponding activities were filtered out and their transferability to the city of Bremen was examined. In the city of Bremen, eight locations and neighbourhoods (including the Tabakquartier and Kellogg-Areal) were examined with regard to their potential for implementing a productive city.

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.

Housing has become a public issue like it hasn't been for years. That is why the competition for the German Building Owner Award 2018 has come at the right time. It is organised by the working group KOOPERATION GdW Bundesverband deutscher Wohnungs- und Immobilienunternehmen, Bund Deutscher Architekten BDA and Deutscher Städtetag (DST).
Initially offered without differentiation, the prize has been awarded in the categories "New Construction" and "Modernisation" since 1997. Due to the increasing complexity and interpenetration of new construction and modernisation projects, this separation will be waived in the 2018 competition. Pure new construction or modernisation projects as well as mixed forms can be submitted.
The organisers invite all interested parties to take part in this competition, which is funded by the Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety.
German Building Award - the most important prize in the field of residential construction in Germany
The competition for the German Building Owners' Award is based on the conflicting priorities of high quality and affordable costs, and aims to highlight the special role of building owners. The working group KOOPERATION GdW-BDA-DST launched this competition in 1986 to support positive approaches and solutions in housing construction.

From the meeting of the Berlin Senate on 24 September 2019:
At its meeting today, the Senate adopted the report to the House of Representatives on "Sustainability in Construction: Berlin Builds with Wood", following a presentation by the Senator for the Environment, Transport and Climate Protection, Regine Günther.
The Senate is consistently pursuing the goal of developing Berlin into a climate-neutral city by 2050. To achieve this ambitious goal, the Berlin Energy and Climate Protection Programme (BEK) in the building sector also includes resource conservation and, in particular, the sustainable construction and refurbishment of buildings.
Through the use of wood as a renewable building material, relevant reductions in greenhouse gas emissions can be achieved for the state of Berlin. For example, the use of one cubic metre of wood in a construction project binds around one tonne of CO2 over the entire useful life of the wood product. If a school for 1,000 pupils is built in timber construction, up to 750 cubic metres of wood are used. This corresponds to a saving of 750 tonnes of CO2.
Senator Günther: "The state of Berlin wants to build even more with wood in its own construction projects. In doing so, Berlin wants to live up to its role model function and motivate as many companies as possible to follow suit. More timber construction is an important element for climate protection."
The state of Berlin has already initiated extensive measures to promote timber construction. It is thanks to these measures, as well as the efforts of the timber trade, the crafts and the timber industry, that urban timber construction is now accepted in Berlin and is developing a high level of dynamism throughout the state.
Due to the importance of timber construction for climate and environmental policy and its great advantages, the Senate is placing even greater emphasis on timber construction, particularly in state-owned, but also in private construction projects. In this context, care must be taken to ensure that the wood used comes exclusively from sustainable forestry and that this is always verified by the submission of a FSC- or an equivalent certificate is documented.
The final report presents the measures already initiated by the Land of Berlin as well as the additional measures planned:
