Amsterdam Westerpark With 600 residential units as a contiguous settlement, the largest settlement for cyclists in the world. The residents organise their everyday life without their own car. This saves the construction and operating costs of the expensive underground car park and it enables the use of the open spaces for purposes other than parking private cars, which do not drive to over 90% but take up space.

Amandus Samsøe Sattler elected new DGNB President | Photo: DGNB
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.
Decentrally generated electricity from renewable energies can cover the demand for electrical energy in Bavaria both in balance and in perspective. This is the result of a joint study by the grid operators Bayernwerk Netz GmbH (Bayernwerk), LEW Verteilnetz GmbH (LVN) and Main-Donau Netzgesellschaft. The Bavarian power grid operators have analysed which development paths are possible for Bavaria with regard to renewable power generation and whether climate neutrality can be achieved in the power sector. The grid operators received scientific support from the Forschungsstelle für Energiewirtschaft e.V. (Research Centre for Energy Economics).
Study describes four scenarios
The current study follows on from the previous study from 2015 and describes the future development of renewable electricity generation in Bavaria. In four scenarios, the forecasts for wind and photovoltaic systems on buildings and open spaces are available in high regional resolution. The two scenarios "Interconnection" and "Regional Generation" look up to the year 2060 and assume complete climate neutrality of electricity generation in Bavaria. This requires a considerable increase in the number of photovoltaic and wind power plants. However, a CO2-neutral electricity supply cannot be achieved if the expansion trend of the last three years is merely continued (Trend scenario) or if the current federal policy framework (Policy scenario) is used as a basis.
Distribution grids as the backbone of a decentralised energy supply system
"We need even more dynamism in the expansion of electricity generation from renewable energies if we want to achieve the idea of a climate-neutral energy supply," says Egon Westphal, technical director of Bayernwerk. "The distribution grids have a central role to play in this. They will continue to be the stable backbone of a decentralised energy supply in the future. The people of Bavaria can rely on this", says Dr. Egon Westphal.
In addition to the further integration of renewable plants into the electricity grid, the foreseeable increase in demand on the electricity grids as a result of new applications such as electromobility will also remain a central task. Through grid expansion, the use of innovative technologies as well as digitalisation and flexibilisation in generation, consumption and storage, the distribution grid operators see themselves well equipped for these tasks. "We can additionally optimise the necessary grid expansion if we can access flexibility options in generation, consumption and storage in a grid-serving manner," explained Dr Egon Westphal. In addition, the distribution grid operators will further intensify their cooperation in order to be able to ensure the safe and efficient operation of the electricity grids in the future as well.
In 2060, green electricity generation may exceed consumption in Bavaria
The two scenarios "interconnection" and "regional generation" are particularly important with regard to climate policy goals. The interconnection scenario assumes a strong nationwide exchange of electricity via transmission lines - the most economical scenario in terms of cost optimisation under today's conditions. In the "Regional Generation" scenario, on the other hand, green electricity is preferably generated locally in Bavaria. In both scenarios, around 60 TWh of green electricity will already be generated in 2030, rising to around 85 TWh in 2060. If current electricity consumption is extrapolated, this amount would cover around 80 percent of electricity consumption in 2030. In 2060, Bavaria's green electricity plants will produce significantly more electricity than is consumed. In perspective, there will be enough renewable electricity available for the electrification of new applications such as electromobility, the expansion of heat pumps or power-to-X measures.
Strong growth in photovoltaics
An important component in both scenarios is the strong expansion of photovoltaic plants: the installed PV capacity on buildings increases from currently 9,500 MW to 21,100 MW in 2030 and 32,400 MW in 2060. In the interconnection scenario, ground-mounted plants also record a significant increase, from currently 3,000 MW to 10,000 MW (2030) and 25,200 MW (2060). While in the regional scenario the expansion of ground-mounted systems is somewhat more restrained, wind power plays a more important role here. The scenario describes an increase in wind power from currently 2,800 MW to 5,700 MW (2030) and 9,300 MW (2060).
Wind power with regional focus
In the regional scenario, the strongest addition of wind power plants occurs in Lower Franconia with +1,500 MW. However, sites in the southern administrative districts (Lower Bavaria: +1,200 MW and Swabia: +1,100 MW) must also be developed in order to achieve the climate protection targets. In the other administrative districts, the expansion amounts to between 550 and 650 MW. In contrast to wind power, the expansion of ground-mounted systems is distributed more evenly across all administrative districts. With 2,300 MW, the largest addition is in the largest administrative district, Upper Bavaria.
More than 60 percent of Bayernwerk's grid is already made up of renewables.
Almost 300,000 plants feed electricity from renewable energies into the Bayernwerk grid, mostly from photovoltaics. In total, these systems have an output of almost 9,000 megawatts. Bayernwerk thus already transports more than 60 percent renewable energy in its grids. The most important energy sources are photovoltaics, hydropower and biomass. Wind plays a subordinate role.

At a press conference today, Lord Mayor Dieter Reiter, together with City Planning Councillor Professor Dr. (l) Elisabeth Merk, presented an overall plan for Munich's mobility in the coming decades.
Where could new underground and tram lines be built, where could the new cycling expressways run, and where can people switch from their cars to environmentally conscious means of transport? The mobility of tomorrow will be characterised by an optimal interlocking of different forms of mobility - first and foremost an optimised and broadly developed public transport system, a wide network of cycle paths, new offers for commuters in so-called HOV lanes ("High-occupancy vehicle lanes"), dedicated bus lanes and clever mobility concepts in settlement development with innovative means of transport.
Not only population and economic growth pose major challenges for transport infrastructure and settlement development, but at the same time the urban goals for traffic safety ("Vision Zero"), the political and legal requirements for environmental and climate protection (air pollution control, CO2 neutrality) and technological progress (digitalisation and networking) must always be taken into account.
Mayor Dieter Reiter: "Only with a well-developed and, above all, cleverly networked mobility will we be able to master the great challenges. The overall concept published today contains many good ideas for the further expansion of our transport infrastructure. The backbone is, of course, local public transport, which we not only want to greatly expand, but also create further tangential and ring connections in its network. I see this look into the future as a good basis and impulse for further debates. However, the mobility of the future can only be successfully developed in cooperation with the Munich region. In recent years, the city council has passed several groundbreaking resolutions for well-connected, environmentally friendly and space-saving mobility. We want to continue this".
City Planning Councillor Professor Dr. (l) Elisabeth Merk. "In the overall concept, we want to bundle all important measures for sustainable transport planning. It is important to us that we tackle it together. In dialogue with citizens and stakeholders from the region".
Expansion of local public transport (ÖPNV)
Public transport is the backbone of sustainable mobility. To encourage even more people to switch from their cars to public transport, the service will be significantly improved - through the new main station, the second main line, new bus lanes, underground and tram lines, increased frequency, more reliability and comfort. The existing network will be decentralised by tangents and, where sensible, supplemented by innovative means of transport such as cable cars or on-demand services. The result is less congestion and freed-up space that can be used, for example, for lanes for express buses, cycle paths or as amenity spaces.
Improving the cycling infrastructure
Cycling in the city is becoming much safer and more attractive. The continuous and safe "Altstadt-Radlring" (Old Town Cycle Ring) demanded by the citizens' petition is being implemented step by step; every quarter, the city council also decides on a bundle of further measures to make the road network significantly more cycle-friendly. This means that the demands of the second citizens' petition "Radentscheid" will be largely realised by 2025. Munich's first cycle path from the Stachus in the direction of Garching and Unterschleißheim as well as five further star-shaped routes will connect the city centre with the surrounding area; a cycle ring connects several city districts.
New offers for the city-countryside commuter traffic
Work-related commuting between the city and the region is made easier: modern Park & Ride facilities are being built on the motorways and main access roads at the gates of the city. From there, express buses continue on to the city centre on separate lanes without traffic jams and loss of time. The occupancy rate of commuting cars is increased by allowing the bus lanes to be shared by vehicles with several occupants. These "high-occupancy vehicle lanes" are already successfully helping to reduce car traffic abroad. For the "first" and "last mile" to and from public transport stops, more sharing and on-demand services will be provided, for example call buses.
Car-reduced city centre
New parking regulations, fewer parking spaces, traffic-calmed zones and sustainable logistics concepts will reduce car traffic in the old town and city centre. The space thus freed up will benefit cycling, walking and public transport as well as the quality of stay and the green and open spaces that are so important for the urban climate. Necessary, unavoidable car journeys into the city centre will still be possible. However, it is primarily emission-free, innovative means of transport that will shape mobility here. Efficient city logistics concepts make delivery and loading traffic compatible.
Mobility concepts
When planning new neighbourhoods and urban renewal projects, mobility concepts are considered from the very beginning. The focus is on a lively, balanced structure of uses in which as many everyday needs as possible can be found in the immediate residential environment. Short distances, good internal and external access to the neighbourhood by public transport, car and bike sharing services enable people to live without their own cars and increase the quality of life.
Innovative means of transport
Mobility is strongly influenced by digitalisation and innovations. The City of Munich takes these up, plans ahead and is open to trends. Automated and connected driving is currently being researched together with partners from business, science and research; a cable car over the Frankfurter Ring is being studied for the north of Munich, which has heavy traffic. With all new technologies, the focus is on user needs.
On Wednesday, 12 February, the City Council will deal with other important resolutions on mobility in Munich in the Committee for Urban Planning and Building Regulations in addition to the draft resolution "Mobility Plan for Munich".
