Hello Erika,
Who can please tell me which documents I am entitled to request from the developer for the acceptance?
No one here can answer that because we do not know your contract with the developer.
I bought a turnkey condominium built to KfW 70 standards. I took advantage of the KfW loan.
Once the construction project is completed, you will soon receive mail from KfW. In it, you will find a kind of questionnaire to be filled out by your developer and accompanied by attachments; then their structural engineer must recalculate and prove to KfW that KfW 70 was actually achieved according to the promotion criteria.
Will I receive:
-Energy certificate?
-Heat calculation? (Because I suspect a thermal bridge)
-Working plans etc?
As I said, that depends on your contract.
As an example – we provide before, during or after the construction project: working plans, structural analysis (reviewed structural analysis, if necessary), soil reports (if required for the construction project, including the chemical report), relevant KfW documents, thermal insulation verification, blower door test, subordinate confirmation for KfW as well as all warranty documents and a list of contacts for the trades.
A thermal bridge is not found in the working plans; they also do not arise exclusively from improper execution! However, they should be avoided as much as possible, although it is not always fully achievable.
So be careful with "suspicions"!
Best regards from the Rhineland
