Fast and sustainable construction, extension and renovation with wood
As part of Expo Real 2019, experts from the timber construction industry came together for the kick-off event of the Holzbau München network. Organiser Andreas Lerge, Managing Director of Wood Real Estate, opened the evening and welcomed his guests with the topics of digitalisation and professionalisation in timber construction. Larger timber construction projects are currently still underrepresented in German cities, but the general demand for living space in Munich will increase by around 250,000 flats by 2025. Reason enough to make urban timber construction the standard through serial construction and industrial prefabrication. The advantages are obvious: systemised construction reduces construction costs, only a few skilled workers are needed on site to assemble prefabricated modules, construction time and noise and traffic pollution are reduced.
Wood is so stable that it can be used to build high-rise buildings and at the same time unrivalled in its lightness that it can be used to add storeys to existing buildings. Another contribution to active climate protection is refurbishment and modernisation with wood, a renewable resource that is more than sufficient. In total, 18 million tonnes of CO2 can be bound in Bavaria alone. Alexander Gumpp, Chairman of the Board of Trustees of proHolz Bayern, believes it is imperative that a life cycle assessment and compliance with emissions limits are a mandatory component of construction projects. An ecological model housing estate is currently being built in Munich: the Prince Eugene Park. An exemplary urban timber construction that creates plenty of living space for many generations. We are committed to a sustainable forestry and timber industry in Bavaria in order to realise more timber construction projects so that we can call Munich a "timber construction city" by 2030.
"BISKO" is neither a sausage nor a new chocolate bar, but the new "Municipal Accounting Standard". After four years of development, a methodology paper is now available that provides clear accounting rules for energy and greenhouse gas balances for municipalities in Germany. In a lengthy consultation process, coordinated and led by ifeu Heidelberg, questions such as "Is it permissible to include green electricity in the balance sheet?" or "Should the electricity mix of the municipality, the state or the federal government be used?" were clarified with scientists, municipalities and consulting institutes. It is hoped that municipal balance sheets will be calculated uniformly in the future and will thus be comparable.
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 International Energy Agency (IEA) expects a boom in photovoltaics over the next five years. Worldwide, installed solar power capacity is expected to grow by 720 gigawatts (GW).
