Renovation of an old building from 1969

Hello dear community We have bought a house which is really good in terms of its structure. It is from 1969, dry, brick-faced and also has a great roof structure. Now of course we have to get to work and renovate it once. Now I have a few questions about it and hope someone can help me ;) 1. Is an energy consultation mandatory and if so, what may it cost? (Apparently there are no subsidies anymore) 2. Is blown-in insulation useful? 3. Can I expect any security or guarantees from the energy consultant? So if a measure doesn’t work and there is mold in the house, can I hold anyone liable? 4. Are there still any funding opportunities at all? Many thanks in advance Regards Dirk

Hello dear community
We bought a house which is really good in terms of substance.
It dates from 1969, is dry, brick-faced, and also has a great roof structure.
Now of course we have to get to work and renovate it once.
I have a few questions about this and hope someone can help me ;)
1. Is an energy consultation mandatory and if so, what may it cost? (Apparently there are no more subsidies)
2. Is blown-in insulation useful?
3. Can I expect any securities or guarantees from the energy consultant? I mean, if a measure doesn’t work out and there is mold in the house, can I hold someone liable?
4. Are there still any subsidies at all?
Thanks in advance

Hello,

regarding 2.: We did it ourselves (cavity wall), it was inexpensive and done very quickly and easily (drilled holes from the inside into the cavity, blew in insulation material, sealed the holes, done). The craftsmen finished at our place in one morning.
Exactly what effect it has is of course difficult for me to quantify. But we didn’t want external wall insulation and since everything was subsidized at 20% and practically cost almost nothing (about €3,000 after subsidies), we decided on blown-in insulation.

Basically regarding subsidies: I believe that subsidies for energy renovations won’t change that much in the new year. Others can probably say more about this.

What is fact there, and what is hope?

Is a useful?

Spare me the ice scraping on the crystal ball and show plans of the existing condition.

Hello everyone and thanks for the responses.

What I have heard is that there are actually no more subsidies for energy-efficient renovation. But I don’t know if that is true or if I misunderstood something.

The heating system is a condensing oil boiler from 2014.

The building’s condition is really good. This was also confirmed to me by a building inspector. Everything is dry, the roof looks as if it was replaced 5 years ago (but it wasn’t).

However, all windows are single-glazed and everything else looks like the style that was popular in the 60s.

My plans are:
All windows new (triple-glazed) Or maybe better double-glazed?
Insulate the facade with blown-in insulation.
The roof slab is made of concrete and I would like to insulate it from above. Probably with rock wool. Or alternatives?
Insulate the basement ceiling with 10 cm of Styrofoam.
Underfloor heating will be installed in 80 percent of the house and milled into the screed.

So far the plan.
An energy consultant is no longer subsidized either. Is this necessary if I won’t receive any building subsidies anyway?

Here are the plans I have:

You can’t really understand that right or wrong because the situation changes every week ;-) In short: the idea of subsidies still exists, but the money is currently not liquid. The climate goals remain, but the effectiveness of the government coalition will still be the subject of, let’s say, sports betting for a while.

The energy consultant has his purpose; he does not exist because of the subsidy. Please don’t confuse "cause and effect."

However, everything is simply glazed and otherwise also everything in the style that was chic in the 60s.

Show the house anyway, especially from the outside. And a cross-section!

All windows new (triple glazed) or rather double glazed?

See my post (not here) "Are three panes better than two?"

Insulate the facade with blown-in insulation.

Apparently, you assume there is an air layer here – I see no indication of that, rather the opposite.

The roof ceiling is made of concrete and I would like to insulate it from above.

I assume you mean the ceiling between the ground floor and the attic. It seems to me we are talking about a bungalow (?)

Underfloor heating will be laid in about 80 percent of the house and milled into the screed.

That sounds a bit like nonsense. Search for the construction description.

What I heard is that there are actually no more subsidies for energy-efficient renovations.

Wrong heard. You can currently still apply for all funds (e.g. KfW 261).

My plans are: All windows new (triple glazed) Or rather double? Insulate the facade with blown insulation. The roof ceiling is made of concrete and I would like to insulate it from above. Probably with rock wool. Or alternatives? Insulate the basement ceiling with 10cm Styrofoam. Underfloor heating will be installed in 80 percent of the house and milled into the screed.

New windows are good. What have you heard about double vs. triple glazing? I see no reason not to take triple (there may be exceptions, but generally there is nothing against it). Where exactly is the blown insulation supposed to go? For that you need an air layer, which I currently cannot see. Or have you already opened up the facade? How is the roof built? Flat roof or "normal"? For a normal concrete floor slab and a non-accessible attic, I would actually spend 1,000€ and apply two layers of mineral wool. Basement ceiling – what room height is available? Styrofoam is cheap but does not bring much with 10 cm. At least PUR 12. Underfloor heating at 80% – why not 100%? You are heating 100% of the house anyway. And why milled in and not just new? Then perhaps a small PUR insulation on the floor is possible and/or you have options for electrical or similar installations. Who is doing the design planning for the heating? Have you already made it heat pump-ready? Or even install a heat pump yourself (the basement is a great place for that) for well under €10k yourself?

An energy consultant is no longer subsidized either. Is this necessary if I don’t get any funding for construction anyway?

Energy consultants are still subsidized. It always depends on where and for what. Necessary? Judging from your initial post, you are a complete layman. So yes, necessary. If you waive funding and build up knowledge yourself, then no – for example, you can use ubakus to calculate which insulation has what effect.
