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.

"International Day of Forests" on 21 March

Storms, drought and insect infestations have caused a great deal of damage to Germany's forests over the past three years. The "International Day of Forests" on 21 March is a good time to become aware of the many services provided by the forest.

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.

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.

What does the EU's CO2 reduction target mean for the German energy transition?

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.

EU climate targets: 55% less greenhouse gases instead of 40% so far

The EU today agreed on stricter climate targets. Accordingly, greenhouse gases are now to be reduced by at least 55 percent below the 1990 level by 2030. Previously, the target was 40% for the same period. For the first time, the EU calculations also include the greenhouse gases stored in forests and other "sinks".

Lower Saxony passes climate protection law

On Wednesday, December 9, 2020, the Lower Saxony state parliament passed what Lower Saxony's Environment and Climate Protection Minister Olaf Lies called a "very important and groundbreaking" law: With the Lower Saxony Climate Act, the topic of climate protection is anchored in the state constitution, the state-wide energy demand is to be completely covered by renewable energies by 2040 and Lower Saxony commits to climate neutrality by 2050. Lies: "With this, we have a law that does justice to the importance of climate protection as the central social task for the coming years and decades. It sets an important course for the future. This is what this state government and the parliamentary groups that support it stand for - setting realistic goals that can also be implemented. We are setting standards and probably have the most ambitious climate law in the whole of Germany! We are consistently pursuing our goal of making Lower Saxony the No. 1 climate protection state. We are already the No. 1 energy state, and we will also achieve this in climate protection!"

Alliance for more climate protection in the construction sector: Federal government must address savings potential in construction and waste disposal

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.

Report (2020) about the first eco-settlement in Saarland

5:18 min, First broadcast: 11/19/2020, Available until 11/20/2021.
Wir im Saarland - The Magazine ∙ SR Television

"A quarter of a century ago, Bernd Janes looked for like-minded comrades-in-arms and founded an ecologically oriented housing estate on the outskirts of Kohlhof. At first, the new neighbors were eyed critically by the surrounding community. No wonder, because the houses were built in wood, four families shared one house and the gardens were not separated from each other by fences, but merged seamlessly into each other."

New DGNB Report on the Sustainable Development Goals

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.

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.

State of Lower Saxony launches funding programme for battery storage systems

The state of Lower Saxony has launched a new funding program for battery storage. The funding guidelines were published in the Lower Saxony Ministerial Gazette on 21 October. Applications can be submitted to the NBank with immediate effect.

The grant funding of up to 40 percent 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, municipalities and many others.

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.

Höfken: "Withdraw capital from fossil sectors - invest in green technologies of the future".

Months of a solar system

"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.
