In the video, the Munich timber housing estate "Prince Eugene Park" and the City of Wood in Bad Aibling. "Drought and bark beetles are causing severe problems for the forest. The resulting damaged timber has caused the price of wood to plummet. Local forest owners are making a loss, although the beetle wood is being exported thousands of kilometres to China and America as construction timber. What could be the solution to the timber shortage? And could more timber construction in our country also be a way out of the climate crisis?"
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.
"New large-scale construction projects and ecological innovations have ensured that Malmö is now a prime example of the direct transition from an industrial metropolis to a sustainable eco city. The secret recipe: the city not only relied on innovative technologies, but above all on the active participation of citizens in the transformation."
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.

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".
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 context of the Green Deal, the EU's tightened targets on the path to climate neutrality envisage a reduction in CO2 emissions of 55% by 2030 and 100% by 2050. Against the background of these tightened parameters, the question arises as to the impact on the energy transition in Germany. Based on its energy system model REMod, Fraunhofer ISE has calculated the consequences of the new EU targets for the expansion of renewable energies in Germany and now presents the results in a short study.
In the EEG draft 
The German government plans to make a number of changes in the rooftop PV segment. According to information from pv magazine, an exemption from trade tax is planned and neighbourhood solutions are to become possible.
Deadline extension! Instead of 31.12.2020 the project submission ends up to and including Friday, 22.01.2021.
Prize for architecture and urban development
The State of Hesse, represented by the Hessian Ministry of Finance and the Chamber of Architects and Town Planners of Hesse jointly offer the award under a specific theme every three years. The theme for 2020 is "Sustainability".
The competition is looking for innovative projects and plans in the field of sustainable planning and construction that have been realised or are currently being realised in Hessen in the last five years.
Emissions targets, some of them significantly improved, show effectiveness of Paris Agreement / But too few commitments for financing climate protection and adaptation to climate change in poorer countries / Chancellor Merkel must swiftly launch international process for additional climate financing
The EU has today agreed on stricter climate targets. Greenhouse gases are now to be reduced by at least 55 per cent below 1990 levels by 2030. The previous target for the same period was 40%. For the first time, the EU calculations also include greenhouse gases stored in forests and other "sinks".
A broad alliance of actors from civil society, science, industry and practice is calling on the German government to promote the climate-friendly construction, maintenance and demolition of buildings. Up to now, only the use phase of buildings has been taken into account in state subsidies for buildings and in the Building Energy Act. There is a complete lack of specifications and consideration of the climate impact of building materials and the construction and disposal of buildings - despite the fact that the construction sector, with its upstream and downstream processes, contributes around 8 percent to German greenhouse gas emissions.
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.
The German Sustainable Building Council (DGNB e.V.) has published a new report explaining how buildings can contribute to the United Nations' global sustainability goals. The publication compares the 17 Sustainable Development Goals (SDGs) with the potential influence of sustainable planning and construction. Architects and planners, as well as building owners and municipalities, are thus provided with orientation as to how they can meaningfully become active in terms of sustainable development. The report also offers a comparison of the SDGs with the criteria of various DGNB certification systems. This shows: Up to 15 of the 17 SDGs are addressed in the context of the DGNB certification of a building project.
With the portal https://energiewendedörfer.de the University of Kassel and Georg-August-Universität Göttingen will present the initial results from the joint project "Innovative concepts and business models for sustainable bioenergy villages - climate-friendly, democratic, citizen-centred". In particular, concepts are being developed for bioenergy and biogas plants that can enable continued economic operation after the current 20-year EEG phase.
On the occasion of the meeting of EU Ministers for Urban Development and Territorial Cohesion on the "New Leipzig Charter", Daniela Wagner, spokesperson for urban development for Alliance 90/The Greens in the German Bundestag, explains:
We welcome the "New Leipzig Charter". Without the transformative power of cities and the ideas and drive of their residents, we will not be able to overcome the challenges of the climate crisis. Nevertheless, the Charter contains significant 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 recognise and prevent dangers in good time. The guiding principle of the healthy city is also not mentioned - despite the heatwaves caused by the climate crisis, a never-ending stream of air pollutants from fossil fuelled combustion engines and the current challenge of a global pandemic.
The German Solar Energy Society e.V. (DGS) and the energy advice service of the consumer advice centre have been cooperating with each other since 1 December 2020. Consumer enquiries from both institutions are answered by the energy advisors of the consumer advice centre. In return, the DGS trains the advisors of the consumer advice centre in the subject area of plug-in solar devices.
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.
The state of Lower Saxony has launched a new funding programme for battery storage systems. The funding guideline was published in the Lower Saxony Ministerial Gazette on 21 October. Applications can be submitted to the NBank with immediate effect.
The subsidy of up to 40 per cent of the net investment costs of a battery storage system applies in connection with the new construction or expansion of PV systems (at least 4 kWp). In addition to natural persons, grant recipients can also be companies, legal entities, local authorities and many others.
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.
"To be climate neutral by 2050, we not only need to make additional investments in green and innovative technologies of the future. Above all, we also need a shift from existing investments in 'brown' raw materials such as coal, oil and gas to 'green' climate-friendly technologies. The phase-out of fossil fuels must be global and rapid, in line with the goals of the World Climate Conference. Only in this way can we realistically achieve the climate protection goals. Churches, municipalities and also companies are setting new standards here and demonstrating the feasibility of the changeover in both ecological and economic terms," said Environment Minister Ulrike Höfken today at the event "Divestment and Sustainable Finance", which took place during the Climate Protection Weeks in Rhineland-Palatinate.
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?
With the gradual dismantling of ten particularly climate-damaging subsidies in the energy, transport and agricultural sectors, Germany could generate up to 46 billion euros in revenue annually. This is the result of a new study by the "Forum Ökologisch-Soziale Marktwirtschaft" commissioned by Greenpeace.
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.
