That was just the Energy Saving Ordinance 2016 vs. fantasy values.

The former values are the relevant ones from 2016.

Answer to the initial question: No

The Energy Saving Ordinance is complicated and poorly structured. The capable and experienced specialist planner (architect) can make a preliminary selection of desired building materials and building constructions for the heat-transferring exterior components as well as for the systems technology (heating, ventilation, air conditioning) during the preliminary design/design phase and can orient themselves on the component specifications of the Energy Saving Ordinance.

Ultimately, however, only the thermal protection certificate from the structural engineer together with detailed calculations provides the final statement as to whether the planned building complies with the requirements (reference building). If not, all adjustment options must be improved until the calculated result matches the requirements of the Energy Saving Ordinance and the Renewable Energy Heat Act, possibly also the KfW (in case of funding or financing through the KfW). The selection of materials is also influenced by statics: aerated concrete blocks with a λ-value of 0.07/0.08 may not be used if their compressive strength is insufficient. In that case, the building design may need to be revised (thicker walls, smaller openings, lower edge pressure).

Have the values from Hausbaugrundriss.de Seems to be an error then.

Got the values from Hausbaugrundriss.de Seems to be an error then.

This is not uncommon at I-Net-Info. Rhineland greetings

Energy Saving Ordinance 2014 Annex 1 and then point 1.2

The table there (Table 2) has been valid since January 2014 and is still valid. It does not specify requirements per component, but only overall.

The tightening from 2016 can be found in exactly this point 1.2 in sentence 2. There, reference is made to the reference building; these reference values are valid for the transmission heat loss for the first time since 2016. For the primary energy demand, however, these reference values have been valid since 2014.

The primary energy demand can be favorably influenced by system technology. In the case of TE, I am 99.99% sure that compliance with the transmission heat loss will always lead to compliance with the primary energy demand. He wants a heat pump and controlled residential ventilation. The primary energy factor of electricity is 1.8. A heat pump with an annual performance factor of 3.6 alone achieves an improvement of the primary energy demand by 50 percent, whereas only 25 percent is required (compared to the reference building with gas).
