Dwindling raw materials, dwindling landfill space and ambitious climate protection targets make it essential to overcome the high use of resources in the construction industry. The film shows that there are already many ways to use building materials sustainably in the cycle: Recycled concrete, recycled gypsum, the reuse and recycling of bricks and the renewable raw material 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.

In addition to the established standard for certifying the sustainability of federal buildings (BNB), the Federal Ministry of Building (BBSR) has also developed a new simplified standard for small residential buildings (BNK). As part of this standard, requirements are also defined for wood products and materials that must be met in order for them to receive full points here. Compliance with these requirements can now also be demonstrated with a WOOD FROM HERE certificate for the wood products.
Significance of the BNK for timber construction
It is the political will that new buildings in Germany should increasingly be subject to sustainability certification. So far, this has failed for the vast majority of buildings, especially smaller ones, due to the enormous costs and the considerable effort required for the corresponding certification. For this reason, the BBSR has developed a simplified standard for small residential buildings. This standard can now be used to certify single-family or multi-family houses more easily. In the meantime, various prefabricated house manufacturers offer their customers a corresponding sustainability certification.
What are the benefits for companies in the timber industry with a certificate for timber from here?
Manufacturers of timber construction products can now fulfil the requirements of the BNK for timber products used by means of a Holz von Hier certificate as an alternative to FSC or PEFC as proof of sustainable forest management. These requirements are set out in the standard's information sheet 3.3.1.
This is of course especially true for timber construction companies in case they want to offer their customers a corresponding certification according to the BNK. In addition to the suitability for the BNK standard, wood from here also offers a direct marketing advantage for timber construction companies, as regionally manufactured products are experiencing a growing trend among consumers and they can thus address a growing target group of environmentally conscious buyers.
The use of the Holz von Hier certification system is very simple for interested companies and involves little administrative, personnel and financial effort. The product- or object-related issuing of a certificate is carried out via an electronic controlling system, similar to the one used in the German biogas register in the context of carbon certificate trading. Holz von Hier thus offers companies in the timber industry additional market opportunities without complicating or restricting their operations.

With the architect Amandus Samsøe Sattler, the German Sustainable Building Council - DGNB e.V. has a new president. He succeeds Prof. Alexander Rudolphi, who will continue his work on the association's executive committee. The change was announced today during the DGNB Sustainability Day in Stuttgart. The election was held on the eve of the event by the ten members of the DGNB Executive Committee. Samsøe Sattler will initially take over the office until the next DGNB general meeting in the middle of next year.
"I am very pleased about the trust placed in me," says Amandus Samsøe Sattler, who has been volunteering as part of the DGNB Executive Committee since 2015. Many developments in recent years, such as the launch of the "Phase Sustainability" initiative, have made the new representative function within the DGNB even more interesting for him, says Samsøe Sattler. Therefore, there will be no fundamental change of course with him as president - on the contrary. "I consider the cooperation with the DGNB office to be very valuable and would like to continue the path the DGNB has taken in recent years." He sees a central task for himself in introducing the topics of sustainability even more strongly to architects, engineers and building owners from the real estate industry.
"We work hand in hand as a team on the board of the DGNB," explains the founder and managing director of the Munich office Allmann Sattler Wappner Architekten. "This will also be the case in the future, except that I will additionally represent our board even more strongly in the future." He is pleased that Alexander Rudolphi will continue to contribute his extensive experience to the DGNB.

Prof. Alexander Rudolphi had held the post as DGNB president for a total of eight years - as founding president in the first year of the association in 2007 and in the last seven years since 2013. "The DGNB has been on a very good path for many years. The core requirements of the assessment and certification system are more correct and up-to-date today than ever before," explains Rudolphi. "At the same time, I am increasingly impatient that the necessary progress is not being made fast enough politically and in the market. Here I would like to work even harder for our common goals in the future. For this I would like more freedom - both in terms of time and content. With Amandus Samsøe Sattler, I know that the office is in the very best hands." In the future, the civil engineer wants to work especially in the political arena in Berlin and for a stronger regional spread of the DGNB in the north-east of Germany.
In addition to Amandus Samsøe Sattler and Prof. Alexander Rudolphi (Rudolphi + Rudolphi), other members include Barbara Ettinger-Brinckmann (Bundearchitektenkammer), Martin Haas (haascookzemmrich - STUDIO 2050), Hermann Horster (BNP Paribas Real Estate), Prof. Anett-Maud Joppien (TU Darmstadt), Prof. Dr.- Ing.Ing. Anke Karmann-Woessner (City of Karlsruhe), Dr.-Ing. Peter Mösle (Drees & Sommer), Prof. Matthias Rudolph (Transsolar) and Prof. Josef Steretzeder (Lindner) to the DGNB Executive Committee.
Various key topics are on the DGNB's agenda for the coming months. For example, cooperation with municipalities in the area of sustainability and climate protection will be intensified as part of a new initiative. The topic of digitalisation will also play a central role at the DGNB in the next six months. In addition, the activities already initiated at the beginning of the year concerning climate-positive buildings - not only in new buildings, but also in existing buildings - will be further intensified.
In this tutorial, Anne Albrecht, building consultant at Faktor X Agentur, shows you in detail how to enter an example house in massive construction into the climate and resource protection tool (KuRT) from start to finish.
What makes a sustainable university? Sustainability Council and 50 university administrations, employees and students are developing a sustainability code for universities. The test phase of the beta version of the university code will start in autumn. In autumn 2014, the German Council for Sustainable Development (RNE) held a stakeholder conference on "From Pilot to Standard: Implementing Sustainability in Research, Teaching and Operations" to discuss the implications [...]
