How can information such as the Energy Saving Ordinance 2016 be accessed?

Is there anywhere layperson-understandable information from which one can see for oneself by which construction measures the conditions for the Energy Saving Ordinance 2016 can be met?

For example, if I want to build with Poroton bricks without additional insulation plus a heat pump plus a ventilation system, I would be interested to know how the dimensions would have to look for it to work - without having to consult a mathematics professor.

In case of doubt, this also depends on other factors such as the insulation of the remaining parts of the building. Furthermore, it depends on the type of brick. Very abstractly, an average 425 T8 or 365 T7 brick is sufficient for you.

I would also like to have such information. Basics for me. Single-story on slab WF approx. 110 sqm 2 people Monolithic and gas condensing boiler a must What additional technology must be installed according to the Energy Saving Ordinance? Best regards. Portoalegre

how is one supposed to answer that - or how is one even supposed to be able to help in any way? "I'm building a house, how much does it cost and what do I have to do for the energy saving ordinance" .. huh?! Do you have a construction service description? Are you building with a planner? Just read through the construction service descriptions of the big [GÜs] - they are available online. That gives you a relatively good idea of what is enough for what and what is not.

Is there anywhere information understandable for laypeople from which one can see for oneself by which structural measures the conditions for the Energy Saving Ordinance 2016 can be achieved?

I claim: No, there is not.

It is a complex topic, the requirement is "dual" (primary energy demand and transmission heat loss). In addition to insulation and airtightness of the building envelope (structural measures), the type of heat generation also matters. This can certainly be explained to a layperson, but the possible measures are diverse because they always have to be considered as a sum of various individual contributions.

My recommendation is to thoroughly read the relevant pages on kfw.de. "Effizienzhaus" is also a lemma on Wikipedia, likewise worth reading and of course with plenty of references (hyperlinks, unfortunately not allowed here, so you'll have to make the effort yourself ...) to the relevant keywords.

Your building will be compared with a reference building, where the transmission heat losses must be at least as good as those of the reference building and the primary energy demand must be 25 percent better. Primary energy demand should not be a problem with a heat pump. With a heat pump and controlled residential ventilation with heat recovery, it is not a problem at all.

The transmission heat loss remains. The reference values (U-values) are as follows:

Wall: 0.28
Roof: 0.20
Window 1.30
Ground slab/basement: 0.35
Equivalent performance must be demonstrated for thermal bridges; don’t ask me which TB catalog now.

If you want to exactly meet the limit values everywhere, then a brick with lambda 0.09 and 300mm or a brick with lambda 0.10 and 365mm or a brick with lambda 0.14 and 490mm will do. Alternatively, as minimal solutions according to reference values, 175mm KS-2.0 and 100mm EPS 032 work. A brick with lambda 0.07 would theoretically suffice with 240mm. However, this probably doesn’t work structurally.

In general, better construction has already been done in recent years. So there is no reason to worry.
