Plan a gallery in the living room energetically and sensibly

Surely it is clear that every feature has its price. Unfortunately, we do not understand the proportionality. How much higher could the monthly heating costs be that such a gallery causes, or how much higher is the energy demand 10 / 20 / 50 %?

Since I wrote that we have an air space, I am speaking up. Unfortunately, I also cannot answer this question for you, since there is no duplicate of our house with the same living conditions, so a real comparison is not possible.

I can only mention that we are very satisfied with our heating consumption. Ultimately, we are all now forced to build according to the energy saving ordinance – and to talk about horrendous heating costs or disproportionality with certain features... well, the building expert has already written something about these points.

But it is also important to us to build energetically sensibly. Unfortunately, these two things hardly reconcile.

If you want to build energetically sensibly, then I would question the double garage in the basement (heated?), the roof terrace above the living room, the open roof, and the roof shape. Also, the exterior area of the house is not proportional to the living and usable area. I would reduce every room by at least 10% of the base area, adjust the window sizes to the minimum, and omit the skylights in the roof anyway.

And again regarding the question: You should compare a compact house with a simple gable roof on a rectangular plot in relation to your very angular house with unnecessary corners and a third gable (shed) – maybe then the obscurity of your question about your desired house will become clear to you. Nothing against your house: I like it a lot and our house also has too many corners...

So if your aim is to explore fundamental proportionalities, then ask yourself what your features bring you, how often you will use your roof terrace, how expensive the window cleaner will be for a) generous window sizes b) unnecessary windows c) windows installed too high.

I understand your argument! One can hardly speak of an energetically optimal construction project. It's about the proportionality of our wishes (garage in the basement/gallery etc.) and the resulting operating costs. But I think we have already been greatly helped in this regard. Thank you very much for that! At least we won't ruin ourselves trying to pay the heating costs .

Heating costs can be neglected in new buildings.
