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.

DIN recommendations for the planning of resource-efficient buildings

Sustainable development in Germany is inconceivable without a resource-efficient construction industry. The new expert recommendation VDI-EE 4802 Sheet 1 explains in a practical way how to apply the concept of resource efficiency in the life cycle of buildings. To this end, it breaks down the tasks and scope for action of the individual players in the construction process. Using examples of increased material, energy and space efficiency, the expert recommendation supports the entire planning process towards a resource-efficient building.

In this tutorial, Anne Albrecht, building consultant at Faktor X Agentur, shows you in detail how to enter an example house in massive construction into the climate and resource protection tool (KuRT) from start to finish.

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.

New Leipzig Charter between aspiration and reality

On the occasion of the meeting of the EU Ministers for Urban Development and Territorial Cohesion on the "New Leipzig Charter", Daniela Wagner, Spokesperson for Urban Development of the Alliance 90/The Greens in the German Bundestag, explains:

We welcome the "New Leipzig Charter". Without the transformational power of cities and the ideas and energy of their inhabitants, we will not be able to meet the challenges of the climate crisis. Nevertheless, the Charter contains considerable gaps. The guiding principle of the resilient city is missing. The development of robust and resilient cities is important in order to better assess risks and to be able to recognise and prevent dangers in good time. Nor is the model of the healthy city mentioned - despite the heat waves caused by the climate crisis, a never-ending stream of air pollutants from fossil combustion engines and the current challenge of a global pandemic.

Book review "Wohnquartier in Holz - Mustersiedlung in München" DBU Bauband 4

The ecological model settlement on a former barracks site in Munich sets new standards in timber construction. Various timber construction methods and building types up to seven storeys are being tested side by side in eight building projects with the aim of a final scientific evaluation. Timber frame, timber frame and timber hybrid construction methods are being used.

Book review "Commercial buildings in clay and wood - added value through material" DBU BauBand 3

Clay and wood in commercial construction are the exception today. But why? Because it is precisely here that these ecological building materials promise many advantages. The examples presented in this publication have one thing in common: they generate enormous added value through the material used in each case. Sometimes the focus is on flexibility and prefabrication, sometimes on the indoor climate or comfort factors, sometimes on durability, user satisfaction, the CO2 balance, recyclability - and sometimes all of these together.

Reportage of the city of Berlin "Resource-efficient building with concrete, gypsum, brick and wood".

Around 60 percent of the resources used in Berlin are processed in the construction industry. This contrasts with millions of tonnes of building rubble and construction site waste. Every year, 2.2 million tons of primary raw materials are already saved in civil engineering and building construction in Berlin through the use of quality-assured secondary raw materials. But Berlin does not intend to stop there. By 2030, a further 1.4 million tonnes of primary materials are to be replaced by secondary raw materials each year.

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?

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.

Hydrogen strategy: EU must end subsidies for fossil fuels

Hydrogen is an important alternative for sectors stuck in the fossil fuel economy. As national governments and European parliamentarians negotiate the EU's hydrogen strategy, EASAC issues a new commentary. "Hydrogen can help reduce our dependence on fossil fuels," says William Gillett, director of EASAC's energy programme. "But the climate benefits are limited if we use fossil fuels to produce it - even with carbon capture and storage. The EU must put an end to fossil fuel subsidies. The fast-growing demand for hydrogen must be met by a massive increase in renewable electricity generation, along with certified imports from third countries."

European Green Deal and German Council Presidency: Climate neutrality can only be achieved with ambitious climate targets

CO2-Emissions should be reduced by 65 percent over the next ten years compared to 1990 in order to achieve climate neutrality - Energy system must be converted to 100 percent renewable energies by 2040 - Investment of 3,000 billion euros required to meet European Green Deal and Paris climate targets - German EU Council Presidency can ensure that Corona aid packages link economic stimulus with climate protection

Federal Cabinet adopts the resource efficiency programme ProgRess III

At the proposal of the Federal Environment Ministry, the Federal Cabinet adopted the third German Resource Efficiency Programme (ProgRess III) on 17 June 2020. With this programme, the government aims to achieve an economical use of raw materials. Companies in particular are to use natural resources more efficiently along the entire value chain. Greater use is to be made of digital solutions to increase resource efficiency. The decision in favour of resource-saving products is to be made easier for citizens through improved information.

Greens: Federal government's raw materials policy is treading water

Dieter Janecek, Spokesperson for Industrial Policy and the Digital Economy, and Dr. Bettina Hoffmann, Spokesperson for Environmental Policy and Environmental Health, comment on today's cabinet meeting and the planned discussion of the draft German Resource Efficiency Programme III (ProgRess III):

With ProgRess III, the German government is treading water. Two resource efficiency programmes of the Federal Government could not prevent the German consumption of raw materials from continuing to rise. It is foreseeable that the third resource programme of the Federal Government will not change this situation either. ProgRess III also remains a longish hodgepodge of plans, announcements and test orders.

With building culture through the Corona crisis: planning and building industry proposes four-point plan

The Federal Chamber of Architects (BAK) and the Federal Foundation for Building Culture, on behalf of the planning and building industry, today presented their proposal for an "Innovation Programme for Building Culture" to politicians in Berlin.

Anne Katrin Bohle, State Secretary in the Federal Ministry of the Interior, for Construction and Home Affairs, accepted the four-point plan. In it, the authors suggest measures to overcome the Corona crisis that will have a sustainable economic and social impact.

Transformation fund for a solidary and ecological restart of the economy

While the emergency aid for companies is getting underway, the debate about possible post-crisis economic stimulus packages is also gaining momentum. The German Green Business Association is proposing a transformation fund to combine a new start for the economy with social aspects and environmental and climate protection.

UBA publishes guidelines for the circular economy

Sustainable development is hardly conceivable without a consistent circular economy. Turning away from a predominantly linear economy requires a change of course. UBA has drawn up guiding principles for politics, business and society which systematically set out the objectives, scope for action, standards of action, requirements and success factors of a circular economy.

Cities without growth - a vision hardly imaginable so far. But climate change,
waste of resources, growing social inequalities, and many other
Future threats are fundamentally calling into question the previous panacea of growth. How do we
we live together today and tomorrow? How do we design a good life for everyone in the city?

France focuses on timber construction and eco-neighborhoods

From 2022, all new public buildings must consist of at least 50 percent wood or other sustainable building material. For buildings with more than eight storeys, the supporting structure must even be made entirely of wood.

It was also decided that 90 ecological neighbourhoods and 100 urban farms should be created in Paris.

BIG sets new standard for sustainable real estate development

Since 1 January 2020, all new buildings and general renovations of the BIG Group have been subject to the Group-wide mandatory minimum sustainable standard.

The BIG minimum standard goes beyond the legal requirements and ensures that all projects of BIG and its subsidiary ARE achieve the klimaaktiv SILVER standard in any case.
The sustainable minimum standard of the Bundesimmobiliengesellschaft (BIG) is a catalogue of criteria that must already be taken into account in the planning process of buildings. This makes the implementation of 43 measures of the BIG Holistic Building Program (HBP)* and the achievement of at least 750 klimaaktiv points mandatory for all new construction and general refurbishment projects for which a plan invention procedure will be carried out from 2020.
By implementing the minimum standard, CO2 emission levels will be significantly reduced, climate-damaging building materials will be avoided and the phase-out of fossil fuels will be accelerated.

Vorarlberg has included the "Holz von Hier" label in the new subsidy guidelines for residential buildings

Recently, the Austrian state of Vorarlberg published the subsidy guidelines for 2020 and 2021 for residential renovation and new construction in the private and public sectors. The climate-friendly procurement of wood and wood products from the region is anchored in these guidelines. The origin of the wood must be proven by means of the "Holz von Hier" label recently introduced in Austria or comparable certificates.

ifeu study "Recyclable Insulation Materials

A research project conducted by natureplus in conjunction with IFEU compares insulation materials with regard to their environmental impact throughout their entire life cycle, including recovery and recycling.

Which insulation material is the best? This question is extremely popular in the construction industry and can ultimately only be answered in the context of the respective construction. In particular, there has so far been a lack of a holistic overview that enables builders and planners to identify the strengths and weaknesses of the various insulation material alternatives in terms of their life cycle assessment, without having to disregard subsequent disposal.

Thuringia will continue to promote municipal climate protection in 2020

Thuringia is making six million euros available this year for investments in municipal climate protection. The funding comes from the state's "Climate Invest" program, which has already kick-started more than 15.5 million euros in investments in municipalities since the start of 2018, the Environment Ministry announced in Erfurt on Thursday. 312 funding applications have been approved.

Buildings with wood as a construction material can become a global CO2 sink

27.01.2020 A material revolution that replaces cement and steel with wood in urban construction can have double benefits for climate stabilization. This is now shown in a study by an international team of scientists. First, it can avoid greenhouse gas emissions from cement and steel production. Secondly, it can turn buildings into carbon sinks, since in the construction timber the CO2 is stored. Although the required amount of wood is theoretically available, such an expansion would require very careful sustainable forest management, the authors emphasize.

BMU/UBA Federal Award "Environment & Building

21.01.2020 Everyone is talking about sustainability - including the construction industry. A prize that the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU) and the Federal Environment Agency (UBA) have been offering since today provides the appropriate topic for discussion: With the new "Federal Award for Environment and Building", which will be awarded for the first time in 2020, the initiators want to distinguish projects with exemplary character in terms of sustainability - not only in the classic areas of existing buildings and new buildings, but also in five other categories. All players in the building sector can apply. The deadline for entries is 15 April 2020.

Further promotion of timber construction in Munich

The Munich City Council's Committee for Urban Planning and Building Regulations has decided to promote the construction of new, contemporary timber construction projects. This year, the city council will develop another grant programme for construction using wood and other renewable raw materials.

The subsidy programme is suitable both for individual projects and for larger housing estates and neighbourhoods. The aim of the city administration is to ensure that around 50 percent of the buildings on municipal land are constructed using timber.

Newly published: Handbook "Urban Production

The aim of the handbook is to provide municipal actors with concrete tools that can be used to keep and locate production in urban areas. In the joint project UrbaneProduktion.Ruhr, funded by the Federal Ministry of Education and Research, research was carried out from October 2016 to December 2019 into whether and how it is possible to bring production back to the city.

New in Schleswig-Holstein State establishes "Competence Centre for Sustainable Procurement and Awarding".
