The new biology and chemistry block at Schubart Grammar School in Aalen – what better place for students and teachers to experience at first hand the interplay between construction excellence and science. Developed by Liebel Architekten BDA in collaboration with Transsolar, the science wing makes groundbreaking use of three environmentally friendly forms of energy: light, thermal energy, and geothermal energy. It’s a pleasant place to learn science. And now it proudly sports a DGNB Climate Positive award.
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.
Completing the last part of the Eisbärhaus – the so-called polar bear house – took almost exactly one year. The ensemble of buildings that lends its name to the animal from the Arctic comprises two existing buildings (Segment A and B) and a now a new building (Segment C). The idea was to do things as differently as possible compared to conventional building projects. Looking back, the architect and the DGNB project auditor tell the story behind the building. It’s a tale of twelve months, torn between the desire to try anything remotely possible, ambitious goals, Swabian records and working with so-called moon phase timber.
The German government has presented the results of its 2020 climate targets. The building sector failed to make the grade. What this means in tangible terms is that simply carrying on as before is not even an option. Immediate action is required. Which means a plan now – as in the next three months. It is therefore quite fitting that – practically simultaneously – the DGNB, Environmental Action Germany (DUH) and the Federal Chamber of Architects (BAK) presented a position paper that is ideal for exactly that.
The construction industry’s transformation towards more sustainability cannot be solved on the basis of only optimising individual buildings. Instead, the focus is shifting to optimising whole districts. The DGNB offers an independent system for this topic. Dr. Stephan Anders, DGNB Head of Certification, has gathered some information on sustainable cities, districts and the challenge of planning sustainable living environments.
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.
Bruno Sauer, CEO of the Green Building Council España, summarises in an interview the introduction of the DGNB System in Spain, talks about special conditions of the Spanish real estate market, the challenges of 2020 and explains why solutions in the building sector must be pan-European.
2020 was also an unusual and challenging year for the construction industry. Nevertheless, projects were realised last year that were impressive and most importantly demonstrate what is possible in terms of sustainability. Clear the stage for a selection of DGNB-certified building projects that prove that 2020 was far from being a lost year in sustainable construction.
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.
Circular Economy or Cradle to Cradle is often talked about when it comes to planning buildings or developing products. The question the logistics and processes at the end of use is hardly ever discussed. But if we do not make deconstruction sustainable and do not close cycles of materials at this point, many problems will remain unsolved. The DGNB would like to change this!
“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. Read More
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.
Understanding and optimising a building in its entirety, creating an aesthetically pleasing and functional company headquarters, making bicycles synonymous with a trendy way of life, living sustainably, driving his business forward – these are the goals entrepreneur Dirk Zedler wanted to achieve with a single construction project. Building the headquarters for Zedler Fahrradwelt is a project, which makes use of the DGNB Sustainability Certificate for Buildings In Use to create an interconnected, sustainable building.
At the moment we have less of a feeling that we could shape our own future. But crises force us to rethink our practice. Today, it is still possible to ignore climate-related issues in planning. But we can change that now – if we want to.
The Chinese Landsea Group, established in 2001, is among the Top 100 Real Estate Developers of the country and specialized on green tech properties. Xie Yuanjian, Vice President and CTO, talks in our interview about the situation of his company in China, the development of green building and efforts to change the industry to the better.
The way we plan and operate our buildings offers enormous potential for saving climate-damaging CO2 emissions. However, to fully exploit this potential, it is important to take an honest, systematic look at our own consumption. DGNB member CSMM – architecture matters has implemented exactly this for its own company. Timo Brehme, founder and managing partner, reports on the motivations, experiences and insights.
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.
As of 2022, all non-residential buildings in Baden-Wuerttemberg that apply for planning permission will be obliged to install photovoltaic (PV) units on a roof area suitable for solar energy systems. This applies to everything from production halls to supermarkets and office buildings. The new requirement was agreed recently by the state government. The DGNB welcomes this move, which it sees as a step in the right direction. All levers now need to be pulled to meet the 2050 climate protection goals. Naturally, this includes the use of solar energy – and there are many more options. Read More
Housing, park, bicycle and pedestrian bridge – the idea of the “Living Bridge Amsterdam” by Dominik Philipp Bernátek is all in one. A hybrid. A future vision of tomorrow’s architecture, which may offer new solutions in the face of increasingly dense cities. In our interview, the architect talks about the project, current challenges and his visions for our cities of the future.
Could headquarter design be a standalone discipline within architecture? More and more companies are keen to convey messages by occupying buildings that make a statement. Zalando has built itself certified headquarters at the heart of Berlin. How does an architect go about ticking all the right boxes for a company like an online retailer?
Networking – a buzzword that nowadays hardly any student or young professional can avoid. At the same time, many wonder whether it is worthwhile to get involved while still at university and whether they have a place between experienced professionals. We spoke with Kasimir Forth on this topic. The Managing Director of the Leonhard Obermeyer Center in Munich got in touch with the DGNB and its network when he was a student himself and continued to participate ever since. His answer: Absolutely! Read More
When it comes to cutting carbon emissions, buildings play a decisive role worldwide. There is considerable potential to improve the net emissions of environmentally harmful gases, not just when constructing buildings but also when operating them. What we need now is urgent action. The question is, what’s the best way to make the environment we build around ourselves ‘fit for the future’? Read More
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!
Described by one state secretary as a gateway to the world, the winner of leading architecture awards and hailed a ‘real win’ by one Lord Mayor, Kottenforst campus wanted its architecture to add value and make some sort of contribution in educational terms. It appears to have done precisely that. This is a project that is well worth a second look.
The 5000th certification was a real milestone for the DGNB. And what kind of project was awarded under this special premise? A rare but special scheme: a laboratory. Reason enough to take a closer look at sustainable laboratories.
Many architecture departments have yet to develop a proper understanding of the role played by sustainability in teaching and research. It’s such an important opportunity to introduce young people to the topic early and pave the way for the future. All universities should place climate protection and the conservation of resources high on their agenda.
In the first three years of the new decade, eight representative European countries work together on how to incentivise low environmental footprint, low risk and healthy buildings which are economically viable. We do so by establishing reliable assessment methods into our countries’ market mechanisms and by providing training on both the usage on specific projects and on the integration into (green) procurement criteria. We focus our activities on public authorities with their huge possibilities to leverage the targets.
Anyone wanting to future-proof their building operations and ensure they are focussed on climate protection must take a number of aspects into account, e.g. emissions caused, cost or location related risks – AND the needs of the users. Despite all ecological and economic considerations, it is important to maintain a holistic perspective. The DGNB System for Buildings in Use takes all of this this into account. It also considers three sociocultural and functional criteria, which we present in more detail in this blog, the final one in our blog series.
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.
Alongside two other buildings, the Watermark Tower forms a kind of quarter within a quarter in Hamburg’s Hafencity. Anyone who builds for the Hanseatic city’s showpiece district will not only find a complex architectural context – but also very special building conditions.
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.
The Nuremberg exhibition centre is expanding. The new exhibition halls mark a turning point, Hall 3C is now a structural highlight of the entire site. But what makes the project and its qualities so special?
If you want to prepare buildings for the future and safeguard the value of your assets in the long term, you’ll need a property strategy that is not only geared to the challenges of climate protection, but also makes sense in economic terms. It will also need to weigh up opportunities and threats for each specific building. This is where the DGNB System for Buildings in Use comes in. We use nine criteria to focus the mind on all kinds of topics with a bearing on sustainability. In a series of blog posts, we describe why it makes sense for all building stakeholders to think more about these topics. In this second post, we consider the economically relevant factors. Read More
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. Read More
There are roughly 20 million buildings in use in Germany alone – millions of properties that highlight so much potential to achieve our climate protection goals. The question is, where do we begin? Is there something every individual can do – in practical terms – to use or operate the buildings they own or occupy more sustainably? This is where the DGNB System for Buildings in Use comes in. We use nine criteria to focus the mind on all factors with a bearing on sustainability. In a series of blog posts, we describe why it makes sense for everyone with a stake in buildings to think more about these topics. In our first post, we look at the three criteria of buildings in use, which are relevant for the environment. Read More
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.
All existing buildings in use in Germany must be carbon-neutral by 2050. This is truly a Herculean task for the entire construction and real estate industry. For building owners, users and real-estate portfolio owners, this means their CO2 balance at the end of the year for ongoing building operations must be zero. For this to succeed, a targeted, holistic and, at the same time, building-specific approach to sustainable optimisation is needed. The system’s solution here is simple.
Modern cities are often too loud. This is not only due to road traffic and aircraft noise, but also to the reflective behaviour of buildings. Sustainably planned facades can help here. A Frankfurt professor has been working on the subject for six years and is calling for a rethink.
As public awareness grows for the need to protect the climate and save resources, there is also increasing demand for appropriate building materials. Manufacturers are expected to ‘do their bit’ in raising the standards of the environment we build around ourselves. There are some interesting ideas out there – but companies need to get more proactive.
Increasingly worrying climate predictions, limited carbon allowances and a rapid rise in public awareness – a lot of things have happened over the last ten years and we’ve all learnt a lot. Against this backdrop, the DGNB has evolved and moved forward, and we face a number of completely new challenges as 2020 gets underway.
“Architecture is a tool to improve lives” is the vision behind and motivation for Anna Heringer’s work. For her experimental approach and outstanding climate resilient and culturally responsive design, the architect received the first Global Award from the Building Sense Now initiative, founded by DGNB CEO Dr. Christine Lemaitre and others. The award ceremony took place in Madrid, alongside the UN Climate Conference. In her talk, Heringer gave insights into her philosophy and work.
“Sustainability in Architecture”: Under this heading guests from the fields of architecture, real estate, research and politics have discussed as part of the event series “Elephant in the room” at the Stuttgart State Academy of Art and Design (ABK). Among other things, they talked about the meaning of the term itself, the right adjusting screws and the question of where the symbolic elephants can be found in the room of sustainable architecture.
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!
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.
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.
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.
DGNB CEO Dr Christine Lemaitre was joined by four architects at Expo Real 2019 to discuss ‘Sustainable Architecture in the Future’ and how this dovetails with their responsibilities, current trends and strategies. They also talked about how sustainability can become the new normal in construction.
The vocational school centre GPES in the north of Stuttgart reached the DGNB highest standard platinum. Eight years later, Thomas Stöckle, head of the “New and extended buildings” department at the school administration office of the state capital Stuttgart, looks back in an interview, talks about the special features of school buildings, the opportunities and challenges of certification and explains what pupils and teachers particularly appreciate.
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. Read More
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.
