The Federal Cabinet today approved the draft of a timber construction initiative presented by Federal Minister of Construction Klara Geywitz and Federal Minister of Agriculture Cem Özdemir. This strategy of the Federal Government is intended to strengthen the use of wood as a sustainable raw material in the construction sector and to ensure more climate protection, resource efficiency and faster construction. With eight fields of action, from the exemplary role of the federal government and the strengthening of research and innovation, to securing skilled labour and knowledge transfer, to securing the supply of raw materials, the use of wood is to be significantly improved and the timber construction quota increased by 2030.

The housing shortage is an immense social problem in many large cities and conurbations. At the same time, the building sector has been failing to meet its environmental and climate targets for years. In a recent position paper, the Federal Environment Agency (UBA) and the Commission for Sustainable Building at the UBA (KNBau) have examined how more affordable housing can be created without unnecessarily harming the environment and health. According to this paper, the most important factor for more environmental protection in housing construction is that the existing building stock is preserved wherever possible or is sensibly converted and repurposed. This is the easiest way to avoid climate emissions and unnecessarily high consumption of raw materials. Today, UBA President Prof. Dr. Dirk Messner presented KNBau's proposals to Federal Minister of Building Klara Geywitz and Federal Minister of the Environment Steffi Lemke in Berlin.
The Federal Ministry of Transport, Building and Urban Affairs is supporting the climate-friendly construction of new buildings with a new funding programme that will start on 1 March 2023. For the first time, the entire life cycle of a building will be considered - from construction to operation to potential deconstruction in the distant future. The buildings are characterised by low greenhouse gas emissions in the life cycle, high energy efficiency, low operating costs and a high proportion of renewable energies for the generation of heat and electricity. This funding thus makes a contribution to climate protection and to meeting national climate targets.
Adjusted for inflation, construction volume will decline in 2022 - Price development and rising interest rates will continue to have a severe impact on the construction industry in the years to come - New residential construction will slump more than the overall construction volume - Policymakers will have to change their strategy in order to achieve their goals for the creation of new housing and energy-efficient building renovation in the medium term
The first results of the timber housing study will be presented at the 15th Congress on Efficient Building with Wood in Urban Areas on 19 October 2022 in Cologne. So far, 118 large-volume housing projects with more than 100 units have been identified across Europe by the HFR researchers, 47 of which are located in Germany. Final results will be presented in early December at the 26th International Timber Construction Forum in Innsbruck on 30 November 2022 and will also be published in a brochure by Informationsdienst Holz.
Recommendations from the BMBF project "Urban Heat Transition" were published: ► Consistently tapping alternative heat sources such as wastewater heat ► Convert public buildings to renewable heat and create neighbourhood heating networks ► Ambitious energy refurbishment in neighbourhood conservation areas to keep rents affordable
Statement by Klara Geywitz on the 2022 budget and the key figures of the financial planning until 2026 The draft budget for 2022 and the key figures of the financial planning up to 2026 provide for a total of 14.5 billion euros in programme funds for social housing. This will support the construction of 100,000 social housing units per year. That is more than three times the original financial planning, which had earmarked four billion euros by 2025. The 2022 budget will lay the foundation for planning with two billion euros.
After a significant decline in the previous year, greenhouse gas emissions in Germany are on the rise again. Thus, around 762 million tonnes of greenhouse gases were released in 2021 - a good 33 million tonnes or 4.5 percent more than in 2020. Overall, emissions in Germany have thus fallen by 38.7 percent since 1990. The increase in the last year is particularly noticeable in the energy sector: This shows an increase of 27 million tonnes CO2-equivalents, as increased demand for electricity, lower electricity generation from renewable energies and the higher gas price led to increased use of coal for electricity generation. Electricity generation from renewables fell by seven per cent, mainly due to poor wind conditions. In the transport and building sectors, emissions were above the annual ceilings set by the Federal Climate Protection Act. This is shown by the latest calculations of the Federal Environment Agency (UBA), which are based on the specifications of the Federal Climate Protection Act and the EU-Renewable Energy Directive (RED) were presented today.
A regenerative heat supply and an innovative rainwater management system are being designed for the "ecoSquare" neighbourhood in Bamberg. Michael Richter and Wolfgang Dickhaut are in charge of the project.

The Federal Ministry of Housing, Urban Development and Building today announced the Federal Urban Green Award 2022. This year, the focus is on the topic of "Climate adaptation and quality of life".
Federal Minister Klara Geywitz: "Climate change is a stress test for our cities. We need more trees for a better urban climate, we need soils that can absorb heavy rainfall, we need less sealed surfaces for more biodiversity and to prevent residential neighbourhoods from heating up. With the Federal Urban Green Award 2022, we are honouring the pioneering work that is already shaping the necessary transformation of cities."
The property developer WvM Immobilien + Projektentwicklung GmbH and the eco-energy supplier NATURSTROM AG found the joint company Green Estate. With the fusion of energy and real estate know-how, the partners are taking a new path to enable people to live sustainably.
With a very large majority, the municipal council decided on 22.07.2021 to initiate the urban development measure (SEM) "Nördlich Hafner". The development statute provides the project with a binding legal framework for the city of Constance and the remaining property owners in the area. The decision is also the conclusion of the preparatory studies (VU) that have been running for about four years, in which not only various subject-related studies and the urban development framework plan were developed, but also a comprehensive timetable and a detailed cost and financing overview were drawn up. The development of the approx. 106 ha area (of which approx. 60 ha are residential areas) including all technical and social infrastructures (e.g. day-care centres, primary school) will cost a total of almost 420 million euros. Income from the allocation of land will ultimately result in a largely balanced overall balance.
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).
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.
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.
Exploit potential at neighbourhood level!
The KfW programme "Energy-efficient urban refurbishment" promotes integrated energy-efficient neighbourhood concepts and refurbishment management with programme part 432. Programme parts 201 and 202 provide investment support for cross-building and infrastructural supply systems. The Federal Ministry of the Interior, for Building and the Home Affairs provides the funding for the energy refurbishment process from the individual building to the neighbourhood from the Energy and Climate Fund (EKF).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.
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.
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.
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.
"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.

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.
Forestry Minister Peter Hauk MdL: "With our call for ideas, we want to further promote municipal timber construction in the state and further consolidate our nationwide position as the No. 1 timber construction state".
A total of around 6.5 million euros in funding from the Baden-Württemberg timber construction campaign is available for the call for ideas for municipal timber construction concepts. The online application deadline is 12 February 2020.
Constance receives project funding for "Hafner KliEn" from the 7th Energy Research Programme of the Federal Government The city of Constance is striving for sustainable urban development. This should include consideration of the triad of sufficiency, efficiency and substitution in the area of energy policy decisions and climate protection. This also and especially applies to the new city district [...].
In the current publication, the wohnbund takes a look at the development of new urban quarters. Backwards - with the question of what became of the goals that were set for individual projects. To the present day - to the concepts that are being implemented in response to current challenges.
Half of the city of Berlin belongs to multimillionaires. This is the conclusion of the Rosa Luxemburg Foundation's current study entitled "Who owns the city? Analysis of ownership groups and their business practices on the Berlin real estate market".
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?
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.
Wohnungsbaugenossenschaft Neues Berlin and Berliner Stadtwerke have agreed on another joint tenant power project. Six solar power systems with an output of around 500 kilowatts are being built in the Mühlengrund housing estate in Hohenschönhausen. Tenants of more than 1,100 apartments will soon be able to benefit from green electricity from their own roofs.
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.
The 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.
Conceptual 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.
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 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.
Jury statement: "The WIR neighbourhood in Berlin is characterised not only by its high energy efficiency (KfW 40 standard) and the use of wood as a renewable raw material for the building construction, but also by the collaborative planning process, which led to different housing concepts and the integration of different social communities. Communal areas and shared facilities such as a residents' workshop, swimming pool, neighbourhood square and daycare centre enable a lively and diverse neighbourhood. This also includes a dementia residential community as well as organisations for youth work and refugee groups. The five apartment blocks were realised with a timber frame construction and the façade in timber panel construction. This resulted in flexible floor plans that offer good conversion options."
