Leading economies discuss raw material consumption
In Argentina today, the twenty largest industrialised and emerging countries are discussing ways and means to use natural resources such as raw materials, water and land more efficiently and sparingly. State Secretary Jochen Flasbarth is opening the conference in Puerto Iguazú today together with Argentina's Environment Minister Bergman. Argentina, which currently holds the presidency of the G20, is thus continuing a political initiative by Germany.
Flasbarth: "If we reduce our resource consumption in the industrialised countries, it will also be easier for us to make progress on climate protection. We need prosperity that makes do with fewer resources. The World Resources Council has shown that we can also benefit economically from this, because resource efficiency is an engine for innovation and new jobs."
According to calculations by the World Resources Council (International Resource Panel), annual raw material consumption of currently 85 billion tonnes by 2050 to 186 billion tonnes if no countermeasures are taken. Resource efficiency and climate protection, on the other hand, could reduce raw material consumption by 28% and greenhouse gas emissions by over 60%, while at the same time increasing global economic output by 1%.
At the G20 Summit in Hamburg in July 2017, the heads of state and government had decided, at Germany's suggestion, to hold an annual G20 Resources Dialogue. After a kick-off meeting in Berlin in November 2017, the conference in Puerto Iguazú is the second meeting of the new governance process. The Resource Dialogue will meet in Puerto Iguazú from 28-29 August, ahead of a G20 working group on climate change.
Back in 2012, Germany was one of the first countries in the world to adopt a national resource efficiency programme (ProgRess). The aim of the programme is to use fewer raw materials and promote the use of recycled materials throughout the entire economic cycle - from raw material extraction to product design and production processes, our consumption patterns and the circular economy.

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.
E-bikes replace conventional delivery bikes and make work easier for letter carriers

Osnabrück/Bonn, 30.03.2017: Deutsche Post today put the 1,000th e-bike of its StreetScooter subsidiary into operation in Osnabrück. The delivery bikes, which are electrically assisted up to 25 km/h, have a payload of up to 50 kg and make the work of letter carriers in urban areas much easier. As with the e-cars ("StreetScooter Work"), Deutsche Post delivery staff were involved in the development. The result is an e-bike that has considerable advantages over conventional electric bicycles in terms of ergonomics, efficiency, load distribution and safety standards. For example, instead of three letter containers, four now fit on the bike. The number of e-bikes is to be further increased in the coming years. In addition, Deutsche Post is testing the "E-Trike" from the StreetScooter company with a payload of up to 90 kg in some delivery districts, also for use in letter delivery.
"We are very serious about our climate protection offensive and are very passionate about it," says Jürgen Gerdes, Member of the Board of Management responsible for Deutsche Post DHL Group. "And in addition to the benefits for the environment, there are additional benefits for our employees, whom we equip with the most modern work tools."
Deutsche Post already operates the largest electric fleet in Germany with around 2,500 StreetScooter Work electric vehicles and a total of around 10,500 pedelecs (e-bikes and e-trikes). In the medium term, the Group intends to replace its entire delivery fleet with electric vehicles.
The e-mobility offensive is part of the ambitious environmental programme GoGreenThe Deutsche Post DHL Group aims to reduce all logistics-related emissions to net zero by 2050. One of the four sub-goals on the way to achieving this is to improve people's quality of life at the local level by 2025 through clean transport solutions.
To this end, the Group wants to switch 70 per cent of its own collection and delivery to clean solutions, for example by bicycle or electric vehicles.
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.

The Market Master Data Register (MaStR) is the register for the German electricity and gas market. Since January 2021, all electricity generation units connected to the general supply grid must be entered in it. This also applies to the steadily growing number of photovoltaic systems in Germany. In addition to the master data on output and location of a PV system, which has already been recorded in the Renewable Energy Sources Act register (EEG system master data), the market master data register records further information such as orientation, inclination and output limitation.
These parameters have now been analyzed by scientists at Fraunhofer ISE. The evaluation covers the period from 2000 to the present day and shows the development over time in terms of number, power, location by federal state, orientation, inclination and power limitation. Different evaluation criteria were taken into consideration, which allow statements to be made on the following aspects: Plant addition, power addition by plant class, plant addition by federal state, plant orientation and inclination angle.
Fraunhofer ISE evaluates these central parameters at regular intervals and makes the results publicly available. In addition, the Institute offers further evaluations of this database on request.
82 percent of the added systems are smaller than 10 kW
The evaluation of the installation of new systems by system class essentially shows that the <10 kW size range has remained constant since 2014 with an average share of 82 percent. Rooftop systems over 10 and up to 100 kW had a heyday between 2004 and 2011, when their share of new installations - in relation to the number of systems - averaged 43 percent.
Growing part of the added capacity is due to large rooftop systems
When examining the increase in capacity by plant class, it becomes clear that the high share of the <10 kW plant class in terms of the number of plants is only reflected in a high increase in capacity to a limited extent. The share of the plant class has remained fairly constant at an average of 19 percent since 2014. One system segment whose relative share of capacity growth has increased sharply is the system class of rooftop systems from 100 to 750 kW. From 17 percent in 2012, their share has more than doubled to 38 percent in 2019. In contrast, the importance of ground-mounted systems has declined from 45 percent in 2012 to 20 percent in 2019.
More than half of the PV systems will no longer be built in Bavaria and Baden-Württemberg
The two states of Bavaria and Baden-Württemberg accounted for an average of 59.6 percent of new installations in Germany between 2000 and 2009, and this share declined to an average of 44.5 percent between 2010 and 2019. Over the same periods, North Rhine-Westphalia increased its average contribution from 14.1 to 18.3 percent, Lower Saxony's share rose from 6.5 to 9.2 percent, and Brandenburg's share increased from 0.7 to 2.2 percent. All the remaining federal states also recorded increases, albeit to a lesser extent. Despite the decline in their share, Bavaria and Baden-Württemberg remain in first and second place in terms of new installations in 2019, with 24.4 percent and 18.6 percent respectively. This is followed by North Rhine-Westphalia, Lower Saxony and Hesse with 17.9 percent, 9.2 percent and 6.1 percent respectively.
73 percent of newly installed PV systems are limited in their capacity
Only around a quarter of the newly installed plants in 2019 do not have any output limitation. According to the EEG, 66 percent of newly installed plants may only feed a maximum of 70 percent of their output into the grid because they do not have remotely controllable feed-in management. This proportion has grown by an average of 4 percentage points per year since 2014. The remaining output-limited plants have even higher limitations of 60 to 50 percent as a result of the combination with a battery storage system.
Increasing proportion of PV systems facing east and west
While the share of PV systems with southern orientation decreased from 61 percent in 2000 to 42 percent in 2019, the share of systems with eastern and western orientation increased at almost the same rate: east from 1 percent in 2000 to 7 percent in 2019, west from 3 percent in 2000 to 9 percent in 2019, east-west from 1 percent in 2000 to 6 percent in 2019.
Plants are increasingly being built with a lower angle of inclination.
The share of added PV systems (rooftop and ground-mounted) with a tilt angle of less than 20 degrees averaged 10 percent between the years 2000 and 2009. Subsequently, between 2010 and 2019, the share increased to an average of 19 percent. Systems with 20 to 40 degrees of tilt accounted for an average of 63 percent between 2000 and 2009, falling to 54 percent between 2010 and 2019.
