In his lecture, Prof. Dr. Henning Austmann addressed the need for cultural change, even beyond the culture of living and building. Technology and politics have hardly been able to achieve any significant progress - let alone the necessary success - in recent years. A rethink and a cultural change are therefore needed so that climate change does not destroy existence on earth.
The lecture recording was made in the context of the symposium "Herbstforum Altbau" in Stuttgart on 21.11.2018.
According to the head of the EIB (European Investment Bank), Werner Hoyer, it is realistic to invest one trillion euros for climate protection within 10 years. In an interview with Der Spiegel, Hoyer said: "If we want to achieve our climate protection goals, we're no longer talking about billions, but trillions of euros" and "We can handle that." EU Commission President Ursula von der Leyen had named the climate protection target when she took office. Hoyer assumes that 1 trillion euro EU climate protection measures will trigger investments totalling 4 trillion euro.
Hoyer wants to mobilise additional money on the capital markets. "If we want to finance climate projects worth an average of 100 billion euros per year and the leverage that our investments trigger is around three, then the EIB would have to raise 30 to 35 billion euros per year," the bank boss told Der Spiegel. Already today, 28 per cent of the EIB's loans flow into projects that serve climate protection: "I want it to become 50 per cent in the future".
The EU target of investing 100 billion per year in climate protection was announced by the new head of the EU Commission Ursula von der Leyen at the 25th Climate Conference COP25 in Madrid. The EU is to become climate neutral by 2050. The EU's first climate protection law will be presented in March 2020.
A study funded by the Federal Ministry of Agriculture determined the potential of hardwood as a substitute for coniferous wood. The results of the study are now available in a brochure published by the Fachagentur Nachwachsende Rohstoffe e. V. (FNR). There is considerable potential for hardwood to be used in industrial timber, but it cannot yet be a substitute for softwood in construction.
Already today, almost twice as much hardwood is provided in Germany as 20 years ago. Beech and oak are the dominant deciduous tree species with a share of 70 %. In wood use, there is considerable potential for using the accumulating hardwood industrial wood as a material. These potentials for low-priced wood assortments lie in particular in the production of wood-based materials such as chipboard or fibreboard. Higher-quality hardwood assortments are suitable, among other things, for windows and exterior doors, solid parquet flooring, interior fittings, solid wood panels and in exterior applications.
Potentials in wood-based materials and interior design
However, the study also makes clear that hardwood can only replace softwood to a limited extent. The timber industry with the key use of building with wood is dependent on softwood. The available hardwood cannot substitute softwood in comparable quantities for technical and economic reasons. The large number of species in hardwood with their widely differing properties makes standardisation difficult. Moreover, processing is usually technically more complex and causes higher costs.
More courage and innovation needed
In order to further develop the potential of hardwood use, the authors recommend, among other things, that companies be more courageous and innovative in establishing and expanding manufacturing processes specialized in hardwood use. In addition, sales-promoting industry communication and marketing for domestic hardwood are crucial for buyer behaviour.
The brochure "Hardwood product markets from a technical-economic and market structure perspective" is available in the Media Libraryavailable.
Background:
A conversion of forests towards more deciduous forests has been taking place in Germany since the 1990s. In particular, beech and oak trees are being planted in the spruce or pine forests. This is intended to make the forests not only more natural but also more stable against external influences such as storms and drought as well as climate change. As a result of the forest conversion, more hardwood will be available as a renewable raw material in the future.
The brochure is based on the BMEL-funded research project "Market potentials of hardwood products from a technical-economic and market-structural point of view - hardwood product markets" by PD Dr. Marcus Knauf, Bielefeld, with the assistance of Prof. Dr. Arno Frühwald, Reinbek.
The research project identified market potentials for products made of hardwood. Product areas in which hardwood is competitive with softwood or can complement softwood were analysed. The analyses were based on official statistics, published market studies, literature, the authors' own experience and interviews with experts. The final report is available at fnr.de under the funding code 22023214 available.
The FNR has been active as a project management agency of the BMEL for the funding programme Renewable Resources since 1993. It also supports research topics in the fields of sustainable forestry and innovative wood use.
Solar Energy Promotion Association of Bavaria (SeV) organises the competition for architecturally and technically sophisticated solar energy systems for the 7th time, with prize money of 27,000 euros
The utilisation of solar energy in and on buildings is a key issue in the context of energy-efficient construction. Solar technology systems should be a natural part of innovative building envelopes as well as components of energy-efficient refurbishment.
The task is to find adequate design realisations for these technical innovations. By integrating solar energy systems into roofs and/or façades in an architecturally and technically sophisticated way, architects can increase awareness of the connection between buildings and solar technology among building owners and the general public and thus help renewable energies to become more widespread.
To increase acceptance and further spread the topic, the SeV is organising the "Building-integrated solar technology 2017" architecture prize.
All architects, owners/operators and solar technology companies - private or commercial, industrial or public - with at least one solar system (solar electricity and/or solar heat) that forms an integral part of the building are eligible to participate worldwide. Commissioning, i.e. the verifiable first energy supply of this system, must have taken place in the period from 1 January 2014 to 30 June 2017.
The closing date for the competition is 31 July 2017.
The first prize is endowed with 15,000 euros, a further 10,000 euros are earmarked for recognition prizes, and an additional 2,000 euros will be made available for a student project.
Research has identified neighbourhoods as an important level of action for climate protection. For this reason, the BMBF, BMU and Federal Ministries of Construction and Transport have funded several research projects on sustainable neighbourhoods, which are now being processed. The consensus of the research projects presented and the funding bodies is that "it is important to economically research neighbourhood concepts for a climate-friendly heat and power supply as well as an environmentally friendly mobility offer" and "to sensibly link the individual elements in the sense of a functioning sector coupling.
The focus articles of the issue "Ökologisches Wirtschaften 3/2019" show on the one hand the potentials of the neighbourhood approach for the implementation of climate protection measures, but also present best practice examples and discuss the feasibility in practice.
The selection criterion for the projects presented was, as is to be expected with the newsletter of the IOER - Institute for Ecological Economy, that members are involved in them. Overall, the contributions provide a good overview of the neighbourhood research projects currently underway in Germany.
