Hello everyone,
despite extensive research, I haven’t been able to fully understand how responsibilities are divided regarding energy requirements/energy performance certificates for a new build.
I hope you can help me.
We are planning to build a detached house and need to comply with the KfW55 standard.
The structural engineer and the certified energy efficiency expert authorized to submit the KfW application are two different people in our case. The question is:
Can the structural engineer carry out all the necessary calculations to meet the KfW55 standard so that the energy efficiency expert only needs to review everything, submit the application, monitor the construction implementation, and finally confirm it?
Or is the structural engineer not allowed to do this, meaning that I also need the energy efficiency expert to perform the planning services to ensure compliance with the KfW55 standard, in addition to the tasks described above?
Thank you very much for your support.

Hello MarcWen,
thank you for your reply. How can I identify an honest, reliable expert? Even though this may be wrong regarding experts who actually are honest and reliable, I initially assume (which is not unreasonable) that everyone aims to earn a good profit; and therefore tends to offer more.
For this reason, I would like to use the help of this forum to find out what the typical responsibilities are (I assume there are standard ones).

That’s not really obvious. How do you usually build? Architects often have a team that takes care of these matters.
As a rough estimate, structural engineer plus review engineer cost about 2% of the construction budget. KfW expert approximately 2,000 euros.
We had a very productive discussion with the architect, structural engineer, and KfW expert.

I am still interested in how the responsibilities are usually divided. If anyone knows something about this, I would appreciate a response.
In our case, the process will probably be that the building application is prepared first with the architect and energy consultant, and then the structural engineer will start their work.
@ MarcWen Why was the discussion with the architect, structural engineer, and KfW expert so productive? Was it necessary to have the structural engineer involved before finalizing the building application? Did the structural engineer also carry out any thermal or energy calculations or verifications?

You don’t need a structural engineer or KfW energy consultant for that. After the building approval, we met together. It then took about 4 weeks during which the structural engineer, architect, and KfW energy consultant actively exchanged information. Then we received our online confirmation for the KfW loan application from the KfW energy consultant. You need this for financing with your bank.
So far, we haven’t received anything from the structural engineer. However, since at the start of construction you must submit to the building authority:
- Proof of sound insulation
- Proof of thermal insulation
- Proof of structural stability
our structural engineer will have prepared those documents accordingly. We will surely be able to review the documents later; currently, we don’t see the need.
In our case, there was the additional requirement that we were not allowed to appoint the KfW energy consultant before April 1st (for 50% funding).
Usually, the structural engineer and KfW energy consultant provide offers detailing all their services.
