ᐅ Penetration for a kitchen exhaust vent in a house (Energy Saving Regulation 2014)?

Recently, we purchased a semi-detached house built to the 2014 Energy Saving Ordinance standard. The kitchen is open, and we cook warm, oily meals every day. Therefore, we would like to have an exhaust vent, even though the house was designed with a ventilation system. Officially, we are not allowed to make a wall penetration. I would just like to ask what might happen if we decide to do this later anyway? What consequences could there be? Thank you.

He has no say in this. The seller says that we are not allowed to drill into the wall because of the energy base. What did you mean by that?
Hi,
what Sebastian meant is:
“it doesn’t matter at all what any seller says. I can do whatever I want with my property, including drilling holes in the wall as I please.”
Depending on the wall construction, however, it is advisable to have this done by professionals.
The only potential issue could be that the KfW standard might change. I’m not sure right now whether a ventilation hood is taken into account in the calculation. If you then fall below the KfW 70 standard but still claim funding for KfW 70, that could indeed be a problem.
Best regards,
Andreas

Apart from the fact that it is my property, that’s not at all what I meant.
Otherwise, windows wouldn’t be allowed to be installed so they can be opened, because the owner could leave them open and waste energy.

The only problem could be that the KFW standard might change. I’m not sure whether an exhaust hood is taken into account in the calculations. If you then fall below the KFW 70 standard but still claim subsidies for KFW 70, that would indeed be an issue.
Best regards,
Andreas Of course, it does affect the KFW calculation because warm air is released uncontrollably. To what extent this really matters can be seen from the calculation. If you are building without KFW funding, there is actually nothing preventing an exhaust hood during construction. Otherwise, it has to be installed later on.

By the way, a chimney doesn’t change anything either...

A range hood and a chimney definitely require a pressure monitor. This means you cannot turn on the range hood, for example, when the fireplace is in use. This could cause issues, for instance, if everyone is sitting by the fireplace at Christmas and someone is still cooking.
I couldn’t quickly find any information regarding KfW either. It seems to be more of an urban legend. I have often heard and read about it during construction, but I have never actually seen the regulation myself. It is probably just an additional effort that construction companies are reluctant to take on.
A range hood is definitely the better option if you cook frequently.
