Construction costs are currently skyrocketing

I have not read the study yet. I will do it when I have time. What is interesting is who financed it. A lot from the construction industry, automotive industry, energy sector, heating manufacturers. So many big players who have an interest in electrifying and energetically modernizing.

From page 102 onwards comes the building sector. Here is a graphic that supports my previous comment regarding the future mix of electricity & gas:



According to estimates, costs of about 1,000,000,000,000 euros (one trillion) will be incurred to achieve the climate goals...

According to estimates, costs of approximately 1,000,000,000,000 euros (one trillion) will come upon us to achieve the climate goals...

well, this is the consequence of the fact that for decades a contradiction between economy and ecology was constructed and propagated by interested parties.

To crown it all, the economy will soon portray itself as the victim of the problems it caused itself.

In principle, the costs must be added to the years of subsidies for fossil fuels...

Well, it's mainly about subsidies. Because you can't force anyone to renew the heating system, the building envelope, or the roof. There have to be incentives for that. Another study estimates that 90% of heating systems are set too high (meaning with too high a flow temperature). If they were set/controlled more efficiently, a tremendous amount could be saved in heating energy alone.

About 12% of German savings assets. Let's go, I would say. A bargain compared to the alternative.

The bigger problem will be implementing the measures - that is, the replacement or installations - through the trades. There are simply too few craftsmen for this mammoth task.
