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.

The BDA Prize for Architectural Criticism 2018 is awarded to the managing editor of the "Süddeutsche Zeitung" and book author Gerhard Matzig.
The BDA Prize for Architectural Criticism looks back on a history of over 50 years. The prize winners have included Julius Posener, Manfred Sack, Wolfgang Pehnt and Peter Sloterdijk. The prize honours "an outstanding achievement in the field of critical debate on questions of planning and building by journalistic means", as the statutes state. The BDA's "Critics' Prize" is in a series with the two other prizes that the BDA Federal Association awards alternately: the "Great BDA Prize" and the "BDA Architecture Prize Nike".
The BDA Prize for Architectural Criticism 2018 will be awarded at a ceremony on 16 June at 4 pm at the Schmidt Theater in Hamburg. The laudatory speech will be held by Dietmar Steiner. The award ceremony is embedded in the program of the 14th BDA Day 2018 in Hamburg.
Today, Federal Minister of Economics and Climate Protection Robert Habeck presented the second PV-The aim is to significantly accelerate the expansion of solar energy in Germany. The goal is to significantly accelerate the expansion of solar energy in Germany. To this end, the strategy identifies measures in a total of eleven fields of action. The spectrum ranges from measures in the area of energy policy to the topics of securing skilled labour, industrial value creation in Europe and technology development. This was preceded by a first photovoltaic summit in March 2023. Since March, the PV strategy has been consulted. More than 600 comments were received.
Federal Minister for Economic Affairs and Climate Protection Robert Habeck says: "Photovoltaics is one of the cheapest energy sources of all and is one of the most important sources of electricity generation of the future. By 2030, the share of renewable energies in gross electricity consumption is to be 80 percent. Photovoltaics, with an installed capacity of 215 gigawatts by 2030, is expected to make an important contribution here. This shows that we have a lot of work ahead of us. But we can see that the expansion is picking up. Last year it was over 7 gigawatts. The interim target for the current year is 9 gigawatts. The chances that we will reach this interim target are good: in the first quarter of 2023, just under 2.7 gigawatts were already added. GW newly installed.
With the strategy presented today, we want to significantly accelerate the expansion and remove all the brakes that have prevented a faster pace of expansion so far".
In recent months, the German government has already launched numerous measures to accelerate the expansion of renewable energies, including increasing the tendering volumes, adjusting the remuneration rates and removing regulatory hurdles. The PV-strategy now focuses on remaining barriers.
Fields of action of the photovoltaic strategy:
Ground-mounted systemsFrom 2026 onwards, we will need an addition of 11 GW
per year. For this, sufficient land must be available and planning and approval procedures must become faster. In addition, innovative concepts such as agri-PV to prevent land competition.
Roof systems: With the PV-strategy, we want to give a boost to the segment of larger building installations in the commercial sector. Also in the area of small PV-The strategy contains improvements and simplifications for the use of the plants. The target is 11 GW Additions per year from 2026.
Tenant electricity and communal building supplyToday, the roofs of apartment buildings are used far too little for PV used. To change this, we will introduce a new model for communal building supply. This will enable the on-site use of solar power for all parties in the building. In addition, we are improving the existing tenant electricity model.
Balcony-PV: We want balconyPV can be easily used by everyone. In addition, bureaucracy should be eliminated and the systems should be able to be connected quickly.
Mains connectionsWe want to significantly accelerate and simplify the grid connection of both ground-mounted and roof-mounted systems. For larger roof systems we will e.g. simplify the certification process.
AcceptanceWe want to strengthen participation. Topics are here a.o. the financial participation of municipalities and simple rules for citizen energy.
Tax lawThe removal of tax obstacles is important for the ramp-up of the PV. Whether e.g. in the case of trade tax or inheritance tax, the BMWK is committed to further improvements for the PV on.
IndustryWe want to build up industrial production capacities for the entire value chain in Germany and Europe, so that the rising demand can be largely met from our own resources.
can be covered by domestic production.
ProfessionalsWe want to increase the number of skilled workers for production,
Planning, installation and maintenance of PV-plants, a.o. through an increase in training offers and advanced training.
Technology developmentWe want to advance technology development along the entire value chain, a.o. within the framework of the upcoming 8th Energy Research Programme.
European frameworkEU processes and requirements increasingly determine the legal framework in the energy sector. We want to accelerate the PV-expansion at the European level, for example with the EU-strategy for solar energy and within the framework of the "Fit for 55" package.
The implementation of the strategy will start immediately after its publication. Some of the measures are to be implemented within the framework of the sog. "Solar Package I" to the cabinet before the summer break. Further measures, some of which require more preparatory work, are to follow in a second solar package. Even during the legislative work, the BMWK open to suggestions: the e-mail address set up for this purpose will remain pv-strategie@bmwk.bund.de also continues to be active.
The NDR has devoted an elaborate feature to the topic "Who owns the road?". Anyone who rides a bike a lot will know many of the situations shown only too well.
Examples from northern Germany, including Oldenburg and Hamburg, as well as the Koppenhagen model with wide and delimited cycle paths and Germany's first fast cycle path in NRW "SR1" will be shown, but also the sense of cycle lanes on the road will be discussed.
