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.


After decision in Spain and WHO demand: German Environmental Aid demands 30 km/h speed limit in built-up areas by 2021

  • Other countries are leading the way: Spain adopts 30 km/h speed limit in cities; French cities with 30 km/h speed limit have 70 percent fewer fatal accidents
  • Federal government fails "Vision Zero" and ignores 30 km/h as an immediate measure in key points paper for new road safety programme
  • Current United Nations Road Safety Week identifies reduction of speed limit to 30 km/h in built-up areas as key measure to protect lives

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.


"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.

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.


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.

"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."
