For those in doubt, time has run out – statement on the IPCC report

What we’re hearing isn’t surprising – sadly – but that doesn’t make it any less shocking or, above all, any less significant: the Sixth Assessment Report on the world climate puts an end to the era of climate change denial. To maintain tolerable levels of life on Earth, decisive action is required now. The only real option available to us is to systematically cut carbon emissions. This is where action is called for across the entire building sector – and time is running out.

Building and biodiversity – our commitment

The 15th UN Biodiversity Conference has been rescheduled to take place in October of this year in the Chinese city of Kunming. At the conference – known as the CBD COP 15 – member states will set a new 10-year strategy until 2030. Currently, the DGNB is the only association in the building sector to have made a clear commitment to the CBD. Why? Because there are many overlaps between building and biodiversity – as this post explains in a nutshell.

The implications of new supply chain legislation for the building sector

Too many firms are still going about business in ways that lead to exploitation of both people and nature. This also applies to the construction industry. Long overdue, the proposed Supply Chain Actin in Germany will bring us a step closer to focusing more attention on this issue. But the requirements still fall short in terms of consistency. The DGNB has a clear vision of what a fair supply chain looks like, and it continues to appeal for more voluntary action.

A new European Bauhaus movement? Count us in!

With its Green Deal, the EU under the leadership of Ursula von der Leyen has caused quite a stir. When it comes to climate protection and sustainability, there’s a new spirit of optimism. It’s right and important that the building industry plays a central role on this path to becoming the ‘first carbon-neutral continent’. The penny has finally dropped and not been ‘lobbied off the stage’ by reservations and objections.

The myth of increased costs due to sustainable building

The myth of increased costs in sustainable building

“I would like to build more sustainably, but the costs…”: The fear of additional costs due to sustainability often leads to doubts and hesitations during planning and implementation. A new study from Denmark now shows with regard to new building construction that this is unfounded. Here it becomes clear: more sustainable does not equal more expensive. On the contrary.

“Structural engineers can make a big difference in terms of sustainability”

Buildings contain a lot of material. These in turn are valuable resources that are becoming increasingly scarce and are responsible for many CO2 emissions. Structural engineers can counteract this consumption of materials on a massive scale. At least that is how professor Patrick Teuffel sees it. We spoke with him about built heavyweights and the current state of research in the world of materials.

Phase Sustainability – exchanging ideas openly and honestly at the first network get-together

Architects and specialist planners involved in the Phase Sustainability initiative ‘met up’ for the first time on 28 July. The main idea of the get-together was to share people’s experiences dealing with sustainability issues when building. By the end of the day, the participants had benefited from a number of long-overdue discussions and gained many valuable insights. Time for Phase Sustainability to enter the next round.

Sustainable urban development – now the cities are talking

Changing travel infrastructures, the green energy transition, climate protection, demand for affordable housing, civil participation schemes, digital transformation – the major challenges of our time are part and parcel of life in the city and conurbations. A great deal has already been undertaken to translate sustainable urban development into action on a municipal level. And demands to do something are no less pressing given the COVID-19 pandemic. Now it’s important to promote transformative power in government administration!

Making the property industry sustainable

It has been a decade since developers started erecting sustainable buildings. They now account for an increasing share of the property market. Now it’s existing buildings that need to catch up. An important point of leverage in achieving this will be to instil sustainability as a fixed feature of the financial industry. There are reasons to be optimistic, however, thanks to initiatives like the European Green Deal and the increasing use of carbon pricing.

A broshure on climate protection

#ClimateActionNow

Any conversation about climate protection and introducing key measures likely to make a real difference quickly moves on to the topic of buildings. Our choices regarding how buildings are planned, constructed and used have a considerable impact on the carbon levels of our planet, which are currently somewhat worrying. But there’s also good news. We can turn things around and make positive contributions to climate protection in the way we need to – but only if we work together, approach things systematically and act as quickly as possible. How specifically this should happen is addressed by a number of services recently announced by the DGNB.

Last yeas Winnder of the DGNB Sustainability Challenge

One year later: How the winners of the last DGNB Sustainability Challenge are doing

Building material recycling, gold of pleasure and green hydrogen: these elements gave three finalists of the DGNB Sustainability Challenge 2019 victory in their respective categories of research, innovation and start-up. It is now almost a year since their presentation at the DGNB Sustainability Day. Reason enough to take a look at how their innovations for more sustainability in the construction and real estate industry have developed since then.

Architects – the conscience of the building sector

The role played by architecture in climate change is not yet entirely clear. We’re still trying to work out if we need to take a new stance on architectural culture. Architects now bear a major responsibility. They have become the ‘conscience of construction’ – the ones expected to ask the right questions. Answering these questions is something we can only do together.

Sustainability with top marks: highlights of 2019

A DGNB Certificate in Platinum means meeting the highest standards for holistic quality in all aspects of sustainability – for new buildings as well as buildings in use and urban districts. To kick off the new year, we would like to take time to look back at a few DGNB certification highlights of 2019 and use them as a source of inspiration for an ambitious 2020. Let’s get started!

Green Solutions Awards

Green Solutions Awards: worldwide role models of sustainable building

192 projects, 37 countries, 3 categories – these are the key statistics of the Green Solutions Awards, recently awarded in France to international beacon projects of sustainable building. The aim of the competition, which is backed by the DGNB, is to highlight reproducible examples of sustainable solutions in the construction sector and urban development industry. Allow us to introduce you to the winners across the main categories.

COP25: Disillusionment and stagnation: 1, Optimism and action: 0

COP25: Disillusionment and stagnation: 1, Optimism and action: 0

What are we doing anyway? This is the question I kept asking myself after going to this year’s UN Climate Change Conference (COP25) in Madrid. Last weekend the COP25 drew to a close, once again without any real results or ambition to show for its efforts. After three days at the conference, this came as no surprise. But instead of shying away from this painful topic, it is now time for some honesty and openness.

An expensive attempt at image cultivation? Five facts showing why that’s not the point of a DGNB certificate

An expensive attempt at image cultivation? Five facts showing why that’s not the point of a DGNB certificate

Once a year, the German Taxpayers Federation (BdSt) publishes its ‘Schwarzbuch’ containing examples of what it considers to be wasteful uses of tax revenues by government departments. The current edition names the DGNB certification system as one such example, under the heading of ‘Expensive Image Cultivation’. This leads us to question whether the selection and research methods used by the authors were as thorough as they should be. In this case at least, it shows that judgement was handed down without understanding the subject in the necessary depth. So here in the blog – with the necessary brevity of the format – we present the most important reasons why certification is actually worth it.

Distinguished for being Climate-Positive – feedback from key stakeholders

Distinguished for being climate-positive – feedback from key stakeholders

You can erect and use a building without having any negative impact on the environment. Really? Is that possible? Yes, it certainly is. Even today. For the first time, the DGNB bestowed its new Climate Positive award on eleven projects at the Expo Real 2019 trade show. We spoke to the designers, architects and users of the award-winning buildings.

Answers to Climate Protection Issues – an interview with DGNB President Prof. Alexander Rudolphi

Answers to Climate Protection Issues – an interview with DGNB President Prof. Alexander Rudolphi

Very few could claim to have influenced German sustainable building developments in Germany as much as Prof. Alexander Rudolphi. To the DGNB, he has been an initiator, founding member and president in one – from the very start. His was reappointed to his post in 2019. We spoke to Rudolphi at the Expo Real trade show in Munich, took a snapshot together and looked beyond the horizon.

Much more than “just” German – the international role played by the DGNB

Yes, it’s true: the D part of the DGNB name stands for Deutsch. We’re German. This has no impact on our operations as an NPO, however: we act on the global stage. Whether it’s in Europe or many other corners of the world, we set up networks and are a much sought-after partner and platform of knowledge for many issues affecting sustainable construction. Probably one of the best examples of this is a recently initiated partnership in Spain.

DGNB & Co. compared – Part 1: basic differences

For many people, the three leading international systems for certifying sustainable buildings – DGNB, LEED and BREEAM – are sometimes used in the same breath and the public perception is that they’re largely interchangeable. But if you take a closer look at the obvious overlaps between the systems, there are actually a number of fundamental differences, so it’s not quite right to consider them synonymous.

The circular economy and its role as a driver of sustainability

Thinking consciously about how natural resources are used has always been a core topic at the DGNB. Right from the beginning, the DGNB has offered a certification system that favours a holistic approach to carbon footprints. Therefore, this has always involved not only the conscious selection of building materials according to their composition and origin, but also a methodical assessment of the ‘reclaimability’ of individual residual materials – all based on strict criteria, criteria that have thus become established in the market.

“Everybody in the project understood the quality improvement“

The DGNB System has been applied in China for some years now and the first projects have already been certified. During BAU Congress China, taking place in July 2016 in Beijing, we talked with two experts that have practical experience in applying the DGNB System on the Chinese market. Their conclusion: The DGNB System is very well received and fits perfectly to the needs of the Chinese market.

Beyond organic: sustainability in the supermarket

When we’re shopping and we think about sustainability, our thoughts quickly turn to the many shades of organic, green and vegan. But the supermarket itself – or rather the building, how it was built and the technical equipment – can also be an impressive testimony to the powers of sustainability, as the retail chain REWE has shown. I recently went on a store visit in the Frankfurt suburb of Praunheim and it was a chance to take a first-hand look at what green building means to the company.
