Workshop "Proper tendering of timber construction projects

at the Sustainable Procurement Symposium in Dortmund on 26 August 2021

The Sustainable Procurement Day is a platform for exchange for procurers and decision-makers from municipalities, private and public institutions as well as churches and companies. Federal Environment Minister Svenja Schulze is the patron. The Agency for Renewable Resources e. V. (FNR), project management agency of the Federal Ministry of Food and Agriculture, will be represented with a workshop on the topic of "Public building and renovation with wood - the right way to tender for timber construction projects" in addition to the stand "The renewable office".

Initiation of the development measure for the new Hafner district in Constance resolved

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.

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

Author of the book review: Roman Schaurhofer, Vienna

The construction volume "Commercial Buildings in Clay and Wood - Added Value through Material" was published in 2020 by Sabine Djahanschah of the Deutsche Bundesstiftung Umwelt (German Federal Foundation for the Environment) at Verlag Detail. The publication, which appeared in book form, deals with the use of the building materials wood and clay in the construction of commercially used buildings. To this end, six buildings with commercial use were analysed in terms of their architectural construction and technical quality features and evaluated with the help of measurements, surveys and life cycle assessments.

Grand Coalition breaks its climate protection promise: Ambitious expansion targets for renewable energies also missing from new EEG resolutions

Sascha Müller-Kraenner, Federal Director of Deutsche Umwelthilfe (DUH), comments on today's discussion of the Renewable Energy Sources Act (EEG) in the Bundestag:

"The grand coalition is breaking its promise to set higher expansion targets for renewable energies for the year 2030 before the end of this election period. An agreement failed mainly due to the energy transition brakemen within the CDU/CSU parliamentary group. In doing so, the federal government is ignoring the implementation of the new EU climate targets and disregarding the decision of the Federal Constitutional Court to tackle more ambitious climate protection measures before 2030. The amendment to the Renewable Energy Sources Act is missing the heart of the matter. As recently as the end of 2020, Federal Economics Minister Peter Altmaier had announced an ambitious expansion path for wind and solar energy for the first quarter of 2021. After a long wait, there was only the famous drop in the ocean: four gigawatts of onshore wind energy and six gigawatts of photovoltaics are the targets for 2022. Longer-term expansion targets? No such thing. Quite obviously, the need for a rapid transformation of our energy supply has not yet reached the CDU/CSU, despite all their climate protection pledges in the election campaign."

Difu report: Major differences in sustainability in German municipalities

Happy Birthday, Passive House!

The passive house turns 30 - pioneering work paves the way for energy efficiency worldwide

The passive house celebrates its 30th birthday! The pioneering project of building physicist Prof. Wolfgang Feist, which started as an experiment, can take great credit: When climate protection was only on the agenda of very few, it paved the way for energy efficiency in buildings. Today, the Passive House Standard is being implemented around the globe, including in impressive lighthouse projects. Other reasons to celebrate: the 25th anniversary of the Passive House Institute and the anniversary edition of the International Passive House Conference.

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.

Sustainability Council launches "Sustainable Municipality Reporting Framework

"Municipalities are crucial drivers for the sustainable development of our society," explains Dr. Werner Schnappauf, Chairman of the German Council for Sustainable Development (RNE). "All 17 sustainability goals are directly or indirectly related to the tasks of a municipality. The new reporting framework sustainable municipality, the BNK, can be a great help for further progress in the field of sustainability", says Schnappauf.

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.

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.

BR-Reportage (44 min., 2021) "With timber construction out of the climate crisis?"

Online until 19.01.2026

In the video contribution, among other things, the Munich timber housing estate "Prince Eugene Park" and the City of Wood in Bad Aibling.

"Drought and bark beetles are taking their toll on the forest. The resulting damaged wood has caused the price of wood to plummet. The local forest owners are making a loss, even though the beetle wood is exported thousands of kilometres to China and America as construction timber. What could be the solution to the timber crisis? And could more timber construction in our country also be a way out of the climate crisis?"


Climate protection foundation Baden-Württemberg starts

The state of Baden-Württemberg is setting an example in climate protection: by 2040 at the latest, the state administration is to operate in a climate-neutral manner. The new Climate Protection Foundation supports it in this by using the interest on its share capital to promote research and development as well as educational projects in the field of climate protection. In addition, the state, municipalities, companies and all citizens can offset their CO2 emissions through compensation payments and thus become climate neutral. The cooperation partner will be the non-profit climate protection organisation myclimate Germany.

Hamburg decides to make photovoltaics compulsory from 2023

On 22.12.2020, the Senate passed the first legal ordinance on the Hamburg Climate Protection Act. This regulates the concrete implementation of the solar roof obligation and the integration of renewable energies when replacing heating systems. With these regulations, Hamburg is one of the pioneers in climate protection in the building sector nationwide.

"Bonn4Future": City and Bonn in Transition sign cooperation agreement

How can Bonn become climate neutral by 2035? This is the question that the participatory project "Bonn4Future - We for the Climate!" would like to discuss together with Bonn citizens over the next two years. Since mid-2019, the climate emergency has been in effect in Bonn; in November 2019, the Council decided that Bonn should become climate neutral by 2035. The city and the non-profit association Bonn im Wandel have now signed a cooperation agreement and thus launched "Bonn4Future".

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.
