When should thermal bridges be addressed?

When it is impossible to detect. I don't think infrared photography is expected. But the likelihood that it warrants compensation is probably low. Then it would need to be a serious fault.
It is probably nearly impossible to build completely without thermal bridges.
What prompts the question?

Hello again,
Thanks for the quick responses. Bought a house this summer. Now that it has gotten colder, I walked around with a thermal camera and found several thermal bridges. However, I don't think it's anything serious yet, but I find these questions interesting.

I would think, and I want to emphasize that this is just a vague theory at most, that you never get a thermal bridge as such to a hidden defect. If it causes damage, such as condensation in the wall resulting in mold growth, perhaps you have something to gain, otherwise, I think it's just to forget about it.
Do the thermal bridges cause any problems?
Then the question is also if you would have offered less for the house if you had known about these conditions.

During every house sale, the buyer should receive a reasonably current energy declaration.tommib said:

Why wouldn't it be hidden? It's hardly something that's easy to find.

Thermal bridges are almost always a consequence of a building method and not a fault.
The question was rather whether it is hidden. But if it is expected, then it is not hidden.

Kwh per year in declaration 21000. But saw in the history at the power grid that it was 31000. 2015 and 2016. But we will burn a lot, so probably won't reach this level in winter.KnockOnWood said:
I'm considering this for my own sake as well, i.e. to reduce energy loss and also prevent addressing problems due to the thermal bridges.
The question is really what the cause of the cold bridge(s) is? If it's a poor construction, then it's not something wrong per se, but if there's been cheating with the insulation, then you could probably hold someone accountable.
I don't think you can generally say that a thermal bridge is never a hidden defect. But there are an endless number of factors that come into play.
But if we imagine a house completed in 2016, and where you discover with a thermal camera that insulation seems to be completely missing in an entire wall.
If we then assume that there is nothing visible indicating that there might be something wrong with this, then I would imagine that there might be reason to claim a hidden defect.
If you discover that insulation is completely missing in a wall from 1950, under otherwise the same conditions, I'm not as optimistic about the outcome if you want to claim a hidden defect.
And then there are all the conceivable intermediate levels. For example, if a thermal camera shows that the insulation has settled in the house from 2016, creating a 10cm gap at the top of all the walls, I would guess it might be worth claiming a hidden defect. If there is a small gap here and there, one should probably consider it as "shit happens."

Energy declarations are tricky. From the total electricity usage, s.k. fixed electricity, household electricity, and, I believe, electricity for water heating are subtracted. All calculated somewhat schematically. But almost all consumed energy contributes to heating, except outdoor lights. So the difference between consumed 31,000 and calculated 21,000 kWh can depend on what is counted as heating.Sm00th said:
