ᐅ Building a House According to the Energy Performance Act: Still Acceptable or Better to Aim for KfW 55 Standard?

Now to the question: would you still build according to the Building Energy Act?

May I ask everyone present what that means exactly? It is the new Building Energy Act, right? So what does the word still imply here?
And I don’t see any indication of whether the house would be built to minimum or higher standards?
Sorry, but in my opinion the question is posed as if this were an old energy regulation, such as KfW 85/70. I’m not fully up to date on the topic either.
However, I can try to answer the question somewhat: if you plan to live in your house for 30+ years, choose the better option. If it’s only for 15+ years because of your age, I would avoid expensive technology.

Building Energy Act = Building Energy Act.
In our case, it came into effect right during the switch to the building permit/planning permission phase. Because of §111 of the Building Energy Act, I wrote a letter to the building authority stating that our house should be calculated according to the new standard (including the use of photovoltaics). You could request the application of the new version, but my letter was never answered; the building authority was not familiar with the topic at all. Several energy consultants were also unaware; their software had apparently not been updated yet.
In this case, I think the original poster is confusing something.

I agree. However, I find the answers confusing because they lack information regarding the energy value.

I interpreted the question as whether, given the clearly visible trend toward KfW55 as the next legal standard level that will not be delayed any longer, we would still build according to the "soon-to-be old" standard Energy Saving Ordinance 2016, which has basically just been renamed as the Building Energy Act.

If you can afford it financially, standards like 40, 40plus, or 55 would certainly be better, also with regard to resale value. However, for various reasons, we ourselves are only building according to the Energy Saving Ordinance.

If you are planning to build soon, the current regulations will apply. The fact that only EH55 may be approved in the medium term is initially irrelevant to you. Renovations of existing buildings are not expected to have to exceed EH70, although I find that quite excessive for many houses. What regulations you will have in 30 years when the first major renovations take place... no one can tell you. My general assumption would be that there won't be further tightening because we are reaching the limits of what is reasonably feasible... but that depends on sensible politicians rather than clueless ideologues.

At this point, I would also consider how the higher standard is achieved. External thermal insulation composite systems (ETICS) would personally be a no-go for me, but they do have their supporters and, for example, allow retrofitting to a higher energy standard by removing the old insulation and applying thicker or better insulation after several decades.

We would have an air-to-water heat pump and a photovoltaic system preparation (in case there is a subsidy for retrofitting in the future).

You probably won’t get any subsidies for retrofitting anymore. The key term is solar obligation for new builds and roof renovations. Either you install it now or you might be out of luck in the long run.
