Even after the EEG reform, most photovoltaic systems on buildings are economical to operate. sonnen GmbH from Wildpoldsried offers a "sonnenFlat". This is particularly interesting for those who already have a PV system and are thinking about adding a battery, but also for anyone planning to purchase a PV system in 2017.
On the following website you can have a look at the offer and the calculations: sonnenFlat
In the video contribution, among other things, the Munich timber housing estate "Prince Eugene Park" and the City of Wood in Bad Aibling.
"Drought and bark beetles are taking their toll on the forest. The resulting damaged wood has caused the price of wood to plummet. The local forest owners are making a loss, even though the beetle wood is exported thousands of kilometres to China and America as construction timber. What could be the solution to the timber crisis? And could more timber construction in our country also be a way out of the climate crisis?"
Scientific scenarios for climate neutrality support the strategy and planning of companies on the path to decarbonisation - Using the example of buildings and heating, climate economists at DIW Berlin analyse existing scenarios for climate neutrality - Net Zero scenarios show a clear path for the transformation of companies and the financial sector - With standardised scenarios and transition plans for climate neutrality, banks, funds and insurance companies can make their portfolios fit for the future
Scenario analyses on the climate-neutral transformation of the economy strengthen the strategic entrepreneurial orientation on the path to climate neutrality. In this context, scientific scenarios and standardised reports in particular support companies in bringing their own business model in line with the path to climate neutrality and reporting on it transparently. This forward-looking information also helps the financial sector. Banks, funds and other financial institutions can use standardised scenario analyses and reports on climate neutrality to identify transformation risks in good time. Therefore, they can make their own portfolios resilient and climate neutral and invest in companies on the path to climate neutrality at an early stage, shows a study by climate economists at the German Institute for Economic Research (DIW Berlin). "Scenarios are a scientific starting point for companies to identify transformation levers and thus reduce their emissions as quickly as possible," says Fernanda Ballesteros, researcher in the Climate Policy Department at DIW Berlin.
Net Zero scenarios show clear path for companies with building portfolio
Ballesteros, together with Karsten Neuhoff, Head of DIW Climate Policy, and other researchers, analysed eight studies on possible climate neutrality by institutions as diverse as the Federal Environment Agency, the Federation of German Industries and Agora Energiewende. Using the example of companies with building portfolios, they worked out what the scenarios mean for corporate strategy on the path to climate neutrality.
"If the climate neutrality target is brought forward to 2035, the reporting on a resulting stress test scenario must be comparable to the core scenario." Karsten Neuhoff
"In the scenarios, the annual renovation rate increases from the current level of around one percent to at least 1.5 to two percent or well over two percent by 2045," write the authors of the DIW study. "The share of technologies based on renewable energies already reaches 46 to 55 per cent in 2030 and rises to 94 to 100 per cent by 2045, with heat pumps being the dominant technology with around 50 per cent," results the analysis of the scientific studies. After heat pumps, district heating follows as the central technology in the scenarios with a share of about 20 to 30 per cent. "The Net Zero scenarios show a clear path," says Ballesteros. "A company with a building portfolio can use the scenarios to see what it needs to implement in the building sector to reduce emissions and become climate neutral."
Standards for comparable reporting strengthen the financial industry
It is crucial for the climate-neutral transformation of the economy that companies document the transformation with comparable transition indicators. "With standardised scenarios and uniform reporting, companies can also show and explain deviations from net zero scenarios," says Karsten Neuhoff, Head of the Climate Policy Department at DIW Berlin. "This also supports new techniques and innovative strategies, which is why the German government should also advocate internationally for the standardisation of forward-looking reporting standards and scenario frameworks." In order for the financial sector to also use this information for analyses, comparable reporting on a company's core scenario in the current political environment is required, for example climate neutrality in 2045. However, a company's transition plan should also be resilient to changes in climate policy. Neuhoff: "If the goal of climate neutrality is brought forward to 2035, the reporting on a resulting stress test scenario must be comparable to the core scenario."
Background: EU and G20 negotiate standards for forward-looking climate reporting
In the Climate Protection Act, Germany has committed itself to gradually achieving climate neutrality by 2045. Companies from industry and the service sector must therefore change their production and business practices, and financial institutions must adjust their assessment criteria. In many cases, this requires a new strategic orientation and investments in climate-neutral products, business models and production technologies. For this, companies need capital and support from the financial sector, which plays a central role in achieving climate goals.
In order for investors, civil society organisations and public authorities to understand the investment needs, progress and potential risks of companies on the path to carbon neutrality, companies are expected to provide forward-looking reporting based on scientific evidence and standardised procedures. The science works with scenarios that also provide industrial and service companies as well as banks, funds and insurance companies with comparable information about the transition to a climate-neutral business model and resulting risks. With the help of the scenarios, companies can consider the transition risks and opportunities in their investment decisions. The scenarios enable the financial sector to decarbonise the portfolio step by step and to map company-specific transition risks and opportunities in risk management.
International climate reporting frameworks are already laying the groundwork for a common scenario framework and standards for forward-looking reporting on the path to climate neutrality. For example, the frameworks of the international Taskforce on Climate-Related Financial Disclosures of the 20 most important industrialised and emerging economies (G20) and the EU, as well as the UK government's Transition Plan Taskforce. Other relevant processes are the negotiations on the planned disclosure requirements of the EU regulatory proposal CSRD (Corporate Sustainability Reporting Directive) and the global sustainability reporting standards of the ISSB (International Sustainability Standards Board).
In addition to the motivation and background of the ecovillage movement, the film also gives a good impression of the Sieben Linden ecovillage.
The text on vimeoHow can a world beyond growth, competition and profit look like? The multimedia project "Degrowth in Bewegung(en)" shows which initiatives and movements develop and live social, ecological and democratic alternatives.
In the ecovillage Sieben Linden we met Christiane Kliemann, who tells us in an interview what makes an ecovillage, how ecovillages are politically engaged and where the relation to degrowth is.
The associations and organisations involved in the Building Alliance (Graphic: NABU)
The energy transition in the building sector has stalled. Less and less is being invested in energy-efficient refurbishment and the Paris climate protection targets are in jeopardy. The reason for this is inadequate advice and the uncertainty of many consumers on the one hand, as well as inadequate government regulations and poorly managed subsidies on the other. For almost two years now, the Building Alliance, an association of environmental and consumer organisations with energy consultants, tradesmen, trade unions, the building industry, architects' associations and the construction industry, has been positioning itself against this. Under the leadership of the Nature and Biodiversity Conservation Union (NABU), numerous natureplus members such as BUND, BAUM e.V. and IG Bau are also working together in favour of more climate protection in the building sector.
In a recent statement, the Building Alliance calls on a new German government to "make the neglected third of the energy transition in the building sector an integral part of an integrated climate protection and energy policy". So far, politicians have "missed the opportunity to make energy-efficient building refurbishment the largest value creation and value retention programme in Germany and thus a real job engine for the domestic economy", criticises Jörg-Andreas Krüger, Deputy Federal Managing Director of NABU. Residential and non-residential buildings must now be addressed more strongly and more specifically than before by the three pillars of "information and advice", "support" and "demand".
A "lack of prioritisation and reliability" has unsettled investors, homeowners, tradespeople and businesses. In order to create reliability, "more transparency is needed in the assessment of buildings" through a standardised, optimised energy performance certificate. In addition, "high-quality, quality-assured advice from trained experts" in accordance with national standards is needed. Politicians must "set the course for reliable and permanent funding for high-quality consulting services and refurbishment measures". The refurbishment costs should be "shared equally between the state, landlords and tenants". At the same time, however, "new, market-based incentives are needed to mobilise additional investment and provide smart incentives", concludes NABU.
