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

Hello everyone,
We are planning to build our house with the company Markon (a regional provider in Berlin and Brandenburg). According to the building performance specifications, the house will be constructed in compliance with the Building Energy Act.
The features, price, and feedback from acquaintances who have built with this company are positive.
Now to the question: would you still choose to build according to the Building Energy Act? Especially considering possible legal changes that might occur due to the new government.
Thank you all and have a great start to the weekend 🙂

and as far as I remember, there was also an expansion of the circuit breaker panel. Wouldn't it be more cost-effective to have the mounts installed during the roof covering? It should be cheaper than doing it afterward. We are having everything done. Two complete roof sides, 13.27 kWp for €16,200 gross including power optimizers.
Regarding the topic of building commissioning: we chose January. This way, we effectively gained almost 12 months on top of the twenty years. I would not recommend December. Fortunately, our air-source heat pump was already installed and was able to run the screed drying program "normally" without an auxiliary heater. However, it was also summer, so the energy consumption remained quite low.

I only asked the electrician if there were any tasks that should be done now because they would be too difficult to do later, and that was his feedback.
For everything else, it’s already too late. The crane will be dismantled tomorrow, and the scaffolding is scheduled to be taken down next week. I won’t have time to make any changes before then.

Two full roof sides, 13.27 kWp for €16,200 gross including power optimizers. That’s just office-theory... I thought the same way initially. Our solar installer said that in that case, you plan something hoping it will fit, but during the later installation you realize that something is off by 2–3 cm (about 1 inch), and you have to redo work anyway. The practical solution is actually to complete the roofing first, and then the solar installer removes individual roof tiles and quickly cuts in the mounts. This works completely smoothly. Where our general contractor roofer and solar installer coordinated was with the installation of storm clamps – those were left out where the mounting system would be installed, based on the corresponding wind load calculations.
