Difu report: Major differences in sustainability in German municipalities

The new National Progress Report on the Implementation of the New Urban Agenda shows the state of sustainability in urban development in German municipalities. The report was prepared by the German Institute of Urban Affairs on behalf of the Federal Institute for Research on Building, Urban Affairs and Spatial Development (BBSR).

25% of Europe's greenhouse gases come from buildings - scientists call for policy change

To live up to its climate change pledge under the Paris Agreement, the European Union must ensure that all 250 million existing buildings, as well as all new buildings in the EU, produce near-zero greenhouse gas emissions. In a new report, European national academies of science, through their association EASAC, call for far-reaching policy action. "Policies have long focused on creating energy-efficient buildings that require less heating and air conditioning or generate renewable energy on site. However, the energy used to operate buildings is only part of the story. We need to broaden the scope and look at emissions from building materials and methods - both for new buildings and for building refurbishment," says William Gillett, Director of EASAC's Energy Programme.

Fraunhofer ISE short study: Increased construction of large rooftop PV systems with small tilt angles

In a recently written short study, scientists from the Department of Energy System Analysis at the Fraunhofer Institute for Solar Energy Systems ISE prepared an evaluation of the Market Master Data Register (MaStR) and the EEG system master data for photovoltaics (PV). Important findings of the analyses were that with 38 percent of the newly installed capacity, the increase in capacity in Germany is increasingly taking place in the segment of rooftop systems larger than 100 kW, 22 percent of the newly built PV systems are erected in a west, east or east-west direction and 19 percent of these systems have tilt angles smaller than 20 degrees.

30 Years DASL Special Award for the French Quarter in Tübingen

The Special price on the topic "Urban development revisited: Prices - Practice - Perspectives" was given to the project Urban development area Stuttgarter Straße, French Quarter in Tübingen. The special prize, which is awarded in parallel to the urban development prize, serves to highlight particularly urgent fields of action in urban development and urban planning. It was awarded on 23.4.2021 on the occasion of the 40th anniversary of the German Urban Development Prize to contributions that had already been recognised with prizes and awards between 1980 and 2010. The judging of the special prize was very complex, as it had to cover a span of 30 years, i.e. a generation, of the achievements of German urban development that were considered outstanding at the time, and, in retrospect, it had to be based on robust, objective criteria that could adequately reflect the complexity of 30 years of urban development history and 30 years of urban development models.

German Urban Development Award 2020 goes toBerlin

The prize is awarded every two years by the German Academy for Urban Development and Regional Planning (DASL) with significant support from the Wüstenrot Foundation. Urban Development Award in the DSP 2020 competition goes to the project Quarter at the former Blumengroßmark in Berlin. With 81 applications, a particularly large number of projects were submitted for the Urban Design Award. The spectrum was very broad: urban-structural-geographical, thematic, structural-spatial. From the new town hall in the urban planning context of a small municipality to the large conversion project of a metropolitan region, the interdisciplinary jury (urban planning, architecture, open space planning, preservation of historical monuments, economics, sociology) was faced with a very difficult decision in many cases.

Study "Urban Production for a Productive 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.

Federal government supports development of the "Büchel" quarter in Aachen with 5.5 million euros

A most welcome piece of news reached the city of Aachen this morning (17 March 2021): Federal Minister Horst Seehofer has announced this year's selection of the "National Projects of Urban Development" and announced that the development of the Büchel old town quarter will receive up to 5.5 million euros in funding. Aachen is thus one of four municipalities in NRW to have been awarded the contract. With the amount of funding, the city is in third place nationwide.

Use calamity wood constructively

"The raw material wood is precious. It is therefore important to use it responsibly and in a way that conserves resources," warns Peter Aicher, Chairman of Holzbau Deutschland. Even if wood is affected by environmental influences or the bark beetle, it does not represent an inferior raw material, but has almost identical properties to conventional construction timber. "If the so-called 'calamity wood' has the same structural quality in terms of load-bearing capacity as conventional sawn timber, it can be used without restrictions," explains Aicher. In addition, the wood retains its important function as a CO2 sink, regardless of external impairments.

DGNB study: No additional costs for sustainable construction

A new study from Denmark takes a look at the costs of sustainable building construction and shows that more sustainable does not automatically mean more expensive. On the contrary. The study by Buus Consult on behalf of the DGNB system partner from Denmark, the Green Building Council Denmark, now provides clarity. In the study, it takes a close look at 37 DGNB-certified buildings.

TRASIQ 2: Transformative strategies for integrated neighbourhood development

Since April 2020, the Öko-Institut has been conducting research into how urban neighbourhoods can be sustainably transformed, using two neighbourhoods in the swarming city of Darmstadt as examples, in the project Transformative Strategies for Integrated Neighbourhood Development (TRASIQ 2). The Federal Ministry of Education and Research is funding the project, which is led by the Öko-Institut and involves the City of Darmstadt, the Institute for Regional and Urban Development Research (ILS) and the "Team Ewen" agency.

Mobility, heat and living space

The project focuses on the research topics of mobility, heat supply and efficient use of living space. Heat supply is an important key to climate-friendly living. How and where, for example, can district heating be expanded in existing properties? How can we increase the share of renewable energies in the heat supply? The size of the living space also contributes to how environmentally friendly a person lives. What needs to be done to ensure that people have the living space they need in their particular phase of life through intelligent apartment swaps? How can neighbourhoods be redesigned so that residents can organise their mobility ecologically?

BUND research award for dissertation on "Transparency in rent increases after energy-related renovations".

Dr. Kirsten David, a researcher at HafenCity University (HCU) Hamburg, has developed an innovative method for determining rent increases after energy efficiency measures: By means of functional cost splitting, rent increases become appropriate and comprehensible. The planning of the energetic measures is also ecologically optimized. For her dissertation entitled "Functional Cost Splitting for the Determination of Rent Increases after Energy Efficiency Measures", the scientist today receives the "BUND Research Award 2020". With the research award, the Bund für Umwelt- und Naturschutz (BUND) honors scientific work on sustainable development.

Wuppertal Institute study presents key points for 1.5 degree target

Glaciers are melting, sea levels are rising, heat waves and heavy rainfall are increasing: The consequences of climate change are visible and tangible worldwide, and the window of opportunity to act is shrinking. In order to significantly limit the global effects of climate change, the emission of greenhouse gases on earth must be drastically reduced. The agreement reached by the international community in Paris in 2015 sets the goal of limiting global warming to well below 2 degrees Celsius, but preferably to 1.5 degrees Celsius. Now, the Wuppertal Institute presented a study with possible cornerstones that can help to achieve the 1.5 degree target by 2035. The study shows that a climate-neutral energy system by 2035 is very ambitious, but in principle feasible, provided that all possible strategies from today's perspective are bundled. This requires, above all, bringing forward and intensifying measures that are described in many studies as necessary to achieve greenhouse gas neutrality by 2050.

BBSR publication "Social Mix and Good Neighbourhoods in Newly Developed Neighbourhoods".

Cover: BBSR, 2020The Institute for Urban Planning and Social Research WEEBER+PARTNER (Stuttgart) examined 16 case studies and interviewed responsible persons in municipal, cooperative and private housing companies. The projects are characterized by a wide range of planning and construction approaches. According to the study, social diversity requires structural diversity: Rental, social and owner-occupied apartments of different sizes and with diverse layouts were created in the new housing quarters. They are socially mixed - even within buildings - with the respective proportions in the neighbourhood being derived from local requirements. The new quarters also offer space for communal forms of living, for example for older people and those in need of care. And they are characterised by an attractively designed and green residential environment. Concept awards promote the planning and implementation of such projects: Through them, plots of land are not allocated according to the highest price, but for the best concept.

BBSR publication on concept awards in neighbourhoods

Cover image: BBSR, BMIConceptual procedures are increasingly establishing themselves as a further instrument of municipal land policy for locations with development potential. Here, the property is not allocated according to the highest price, but according to the concept that promises the most sustainable approaches to the further development of the neighbourhood. In this way, the procedures offer municipalities approaches to solving two current and urgent problems: the need for high-quality urban development and affordable housing.

DIW-Wärmemonitor: German households heat slightly less - CO2 emissions hardly fall at all

© DIW Berlin Annual DIW Heat Monitor based on data from energy service provider ista Deutschland GmbH: Heating energy demand in residential buildings declines again for the first time since 2015 - Rising prices, however, cause heating expenditure to increase by 2.4 percent - CO2emissions have fallen by 21 percent overall since 2010, but by only 2.6 percent when adjusted for temperature - Energy-efficient renovation in residential buildings almost stagnant

UmweltBank develops sustainable urban quarter in Nuremberg

UmweltBank has acquired the former GfK site on Nuremberg's Nordwestring. The company is planning an ecologically and socially sustainable urban quarter with housing, a daycare center, commercial space and public green areas. The new headquarters of the green bank will also be part of the quarter. The previous owner, a joint venture of Pegasus Capital Partners and Art-Invest Real Estate, had already developed an urban development concept in recent years and coordinated it with the City of Nuremberg. UmweltBank would like to further develop this concept in line with its own requirements in close cooperation with the city.

Video (2020) Federal Award for Environment & Building for the WIR quarter in Berlin

"The WIR neighbourhood in Berlin is not only characterised by its high energy efficiency (KfW 40 standard) and the use of wood as a renewable raw material for the building structure, but also by the collaborative planning process, which led to different housing concepts and the integration of different social communities. Common areas and community facilities such as a residents' workshop, swimming pool, neighbourhood square and daycare centre, facilitate a lively and diverse neighbourhood. This also includes a dementia residential community as well as sponsors for youth work and refugee groups. The five apartment buildings were built with a timber frame construction and the façade in timber panel construction. This created flexible floor plans that offer good conversion possibilities."

Deutsche Wohnen's push to finance building refurbishments

Climate protection is important to over 80 percent of Germans - but this should not be reflected in higher rental costs. In order to increase the acceptance of energy-efficient renovations, Deutsche Wohnen has developed a model of how climate protection and social compatibility can come together. The "Concept for Socially Compatible Climate Protection in the Building Sector" aims to significantly increase the rate of refurbishment in existing buildings in order to achieve national climate protection targets. At the same time, an economic stimulus package worth billions is being initiated.

Bundestag passes new building energy law

On 18 June 2020, the German Bundestag passed the Building Energy Act (GEG) in its third reading. With this law, the federal government is combining the existing requirements of the Energy Saving Ordinance (EnEV), the Renewable Energies Heat Act (EEWärmeG) and the Energy Saving Act (EnEG). For the information programme Zukunft Altbau (Future of Old Buildings), which is supported by the Baden-Württemberg Ministry of the Environment, the specifications of the new law are not ambitious enough. To bring climate-friendly building and renovation nationwide on the way is not possible in the future. "The legislator has missed it to introduce more demanding standards," says Frank Hettler of Zukunft Altbau. "For a sustainable building stock in Germany, however, these are urgently needed to achieve the climate targets." The GEG will now be forwarded to the Bundesrat, which, however, does not require approval, and is expected to come into force by the end of the year.

State parliament wants compulsory solar energy in Bremen

The parliament of Bremen wants to oblige the use of solar energy on all new and existing buildings in Bremen and Bremerhaven. Whenever the roof surface is completely renewed, they are to be equipped with a solar system in the future. This is photovoltaics and, if necessary, also solar thermal energy. The Senate is currently examining the latter.

"Climate neutrality in urban neighbourhoods" in the issue "Ökologisches Wirtschaften 3/2019".

Research has identified neighbourhoods as an important level of action for climate protection. For this reason, the BMBF, BMU and Federal Ministries of Construction and Transport have funded several research projects on sustainable neighbourhoods, which are now being processed. The consensus of the research projects presented and the funding bodies is that "it is important to economically research neighbourhood concepts for a climate-friendly heat and power supply as well as an environmentally friendly mobility offer" and "to sensibly link the individual elements in the sense of a functioning sector coupling.

The focus articles of the issue "Ökologisches Wirtschaften 3/2019" show on the one hand the potentials of the neighbourhood approach for the implementation of climate protection measures, but also present best practice examples and discuss the feasibility in practice.
