Solar construction and retrofitting obligation for all buildings and structural systems?

Climate-active despite Brexit Great Britain has declared the "climate emergency" - just like London, Los Angeles, Oakland, Vancouver, Basel, now Constance - while in Germany even in some environmental protection circles there are discussions about whether the word should be used at all. And about what a “climate emergency” is supposed to mean and bring about.

On the Brexit-shaken island of our neighbors, the answer of many municipalities is: "CO2 neutral by 2030" in Great Britain

Fear and discouragement in the country of the "climate chancellor" In the country of "climate chancellor" Angela Merkel, her successor as CDU party leader tries to explain that it is better to make CO2 more expensive through the trade in EU certificates than through a tax or levy. I am well aware that we have been trying for decades in the EU to get the right approach to increasing and reducing emissions higher. The issue would then be postponed to Brussels for many years, and if something came from there, one could scold the EU again to emphasize how important the EU is for all of us. I hope that voters in the EU election will massively punish this stupidly daring attempt to deceive voters and will clearly choose parties that really take climate protection seriously. And are also able to see

Acting means working in detail - the economy is there.
But these parties also have to act if they come under government responsibility. And since solar energy has become so cheap that every installation can also be economically represented in Germany, I want to take a really brave, drastic step for discussion. Mind you, only on the basis of the clear finding that these steps, in addition to your well-being for species and the environment in general, are already economical today and can therefore also be used from this side.

A "solar retrofitting obligation for all buildings and structural systems" We are already retrofitting in the existing building against the background of safety and health care: smoke detectors are one example, "dispensing systems" for water samples as part of the now mandatory legionella tests. Both go hand in hand with installation costs and running costs for maintenance, laboratories, batteries and their replacement. In return, users receive a higher standard of general interest. The necessary provision of general interest in climate protection - including protection against the catastrophic consequences of a shortage of oil and gas - goes far beyond that and therefore a real "solar construction and retrofitting obligation" is required.

Duty to build a new building is easy, for all building applications from 1.1.2020, extensive use of solar energy on the building is mandatory. So not something - as is tried in solar thermal with a kind of mini building obligation for new buildings - but right: Without offsetting with the EnEV, without massive exceptions and beyond: By 2030, all buildings and constructional must begin in 2020 in defined tranches Systems to protect the population can be retrofitted with solar systems. This means all south, west, east and, in the case of flat roof pitches, also the north roofs. So not a mini performance, but seriously, right. Basically in facades for new buildings. Since the operation will always be economical, the principle of economy does not conflict with this. Who can not finance it alone receives funding directly from KfW. Before this, the laws for solidary self-generation and neighborhood solutions are adjusted and the then mostly completely local consumption or its suitable storage of solar power is regulated accordingly. Standards will be accelerated and primarily adapted to the new products, as will measurement and counting specifications. All experience a massive increase in the otherwise often pitiful speed in the context of a renewable acceleration law. Only a list of "core monuments" may not be covered with solar systems, the same applies to the compatible cultivation of thermal insulation in view of the regionally arbitrary anti-requirements of the monument authorities in hardly defined ensembles. The Acceleration Act also supports products

Provide areas in parallel across Germany In addition to the obligation to retrofit buildings on buildings, each federal state must show at least 1% of its area for solar and wind (hybrid) use. Planning procedures are shortened and the options for bringing complaints are restricted to one instance. All existing mining areas are rededicated for the primary use of solar and wind energy using the construction notification procedure and exempt from the higher planning law.

There will be many other areas that block faster expansion today. As was also impressively stated at the PV symposium in Staffelstein 2019, this is hardly an issue of the pure PV costs but of the many other hurdles. So they have to be tackled in their entirety and no backward discussion about individual remuneration rates has to be raised. Profitability is there, especially when markets are finally becoming fairer, for example through genuine CO2 certificates, and investments by KfW or similar loans are easier for society to shoulder. But without some pressure, many people don`t do anything - and that won`t work if we really want to decarbonize.
