The EFH is dead, long live the new EFH!
But why is everything concentrated so close to the 0 line? It is a failure due to wrong target setting. People have focused only on reducing space heating demand.
The primary energy indicator according to the Salzburg building code shows energy consumption for building materials and 30 years of household electricity, space heating and hot water and 30 years of energy production. According to the estimate of the expert who designed this primary energy indicator, single-family houses between 1960 and 1969 may have been there at 300 to 500. At that time, 2,000 liters of heating oil per year was typical, and that alone is enough for an extremely high value.
Today, everything is happening just before the 0 line. The primary energy indicator must be below 40 for a building permit. 8,000 € more housing subsidy if this is below 13. This is a de facto photovoltaic obligation, because most buildings without photovoltaics do not get below 40.
Not even passive houses! These focus only on the space heating requirement in kWh of heat, but do not pay attention to the electricity required to generate this heat. Electricity heating elements in the ventilation system I was horrified to see when I January 2020 froze for hours in a passive house.
But why is everything concentrated so close to the 0 line? It is a failure due to wrong target setting. People have focused only on reducing the space heating demand. Objective should have been the opposite of an old house, generate as much energy as an old house consumed. Of course, this must go far beyond space heating needs: mobility! The diesel revolution was not until later, in 1973, with the Golf I. In 1960, diesel engines were used almost exclusively by cab drivers. 27 seconds from 0 to 100 was the argument against the diesel. When starting, the Rudolf Diesel commemorative minute for pre-glowing. So, in addition to the 2,000 liters of fuel oil, 2,000 liters of gasoline were added for about 20,000 km a year. How do you import so much petroleum? By exporting many goods, which are also produced again with high energy expenditure.
This was a society that depended on cheap energy imports. The price difference between the energy imports and the products made with this cheap energy for export. This was a society that, for cheap energy, committed the most unbelievable crimes: such as sucking away a Western-educated, Western-oriented, democratically elected president just because he wanted to raise the price of oil, Operation AJAX.
The exact definition of the primary energy indicator has only been available since 2016, but in the past it was also possible to calculate with kWh and kg CO2 emissions. So instead of the 0 target, it would have been reasonable to move from 400 to -400. The plus and minus signs alone show the confusion of the approach: Why does the primary energy indicator have the sign reversed? Thus, one must always emphasize that the lower, the better.
In September 2019, the first preliminary energy certificate for the GEMINI next generation house was made: -262 was achieved. This could be improved to -337 by October 2022.
The opposite of an energy waster is an energy producer. We can no longer afford energy wasters! As soon as mobility and energy for production are included, practically all of today's houses are energy wasters. On the other hand, we need a lot of energy producers for a functioning energy transition.
How the implementation of the new building standard KlimaSchutzÜberlegenheitsHaus reduces costs by selling electricity on the spot market.

A new shareholder said "I with my very modest investment", but 4,000 times 1,000 € is also 4 million for all investments until the opening of the settlement in Unken as a starting point for worldwide expansion.
Only the Annual General Meeting can resolve the major capital increases, but here is what the Executive Board and Supervisory Board can resolve. The new capital stock is used to perfect the documents for the larger planned capital increases.
Here are the details.
