KfW from 57 to 55 - Calculation and Certification, Expert

If you apply for KFW55, you also need construction supervision. And then, in the end, you might end up spending more money than the €2500 subsidy.

H`t still counts. You have to go from 85% to 70% of the reference building. With a detailed thermal bridge verification, you can still optimize it mathematically.

Do you already have the calculations electronically and can you upload them here?

Thanks for the hint. We are currently at 76% for H`t. What does H`t mean? I didn’t quite understand that.
Unfortunately, I don’t have it electronically yet. I will call the energy consultant on Monday and ask what he means. Then I will upload it here.

Thanks. I feared that. Can anyone say more precisely what this construction supervision costs? Depending on that, I might skip the whole effort...

H`t assesses the heat loss through the building envelope. So an evaluation of the insulation properties of all components of the building.

For KfW70 you already need construction supervision. So ask your energy consultant if the supervision is more expensive for 55.

And what he uses for a detailed thermal bridge certificate.

For KfW70 you also already need construction supervision. So ask your energy consultant if the supervision is more expensive at 55.

But not according to the Energy Saving Ordinance 2009. There you have to meet some requirements, but you do not need supervision by a GEB.

To my knowledge, the funding conditions of KfW apply. And the letters for all applications after 30.06.2014 require accompaniment!

And according to the Energy Saving Ordinance 2009, construction is no longer possible. The Energy Saving Ordinance 2014 with stricter requirements, which automatically comes into effect at the end of 2015, already exists.

eeepad: Ok, if all of that is already in effect, I naturally do not want to contradict you. My understanding was that all of this only applies from the end of 15.
