Must the dream of owning a home remain just a dream?

Hello Parcus,

Moreover, it cannot be a KfW 70 efficiency house at all.,...

and what leads you to this statement?

smiling regards

Hello!

Thanks first for the answers.

I am a bit wiser now. I assume that I can probably forget about the whole thing. Own work is indeed planned, but since we both work in shifts and therefore rarely find time together, the expansion in EL would probably take a long time. And since we are currently renting, the double burden that would then arise would be too much for us...

So it must probably remain a dream after all!

Still, thanks for the effort!

Regards

try to generate equity capital.
The KfW will surely continue its programs until 2020,
because the EU decision would only be implemented then.

For EL you also need time and NERVES.
If it drags on too long, the air is simply out.

the depicted building envelope. HVAC aside.

In addition, there are only a few who can really plan and implement cleanly in aerated concrete or Poroton. Many things require special solutions, which also have their price. Here I would always stay away from cheap.
Thermal bridges are created far too quickly, or the limit of load-bearing capacity is reached. There is also no masonry through which cracks can form faster.

Yes, that would be an option, although at the moment we could have bought a plot of land cheaply. That won't be the case so quickly in the future, at least not for 85,- €/sqm..

Consequently, it will probably work even less!

What bothers me is that the same amount we could save monthly, we throw out the window every month for rent. For example, if I could save €6000 annually, I would annoyingly lose the same money without any return.. :(

Well, it can't be helped...

@Parcus

the depicted building envelope.

From inside to outside: 1.0 cm gypsum interior plaster, 36.5 cm aerated concrete, and 2.5 cm minimum exterior plaster; alternatively and cost-neutral: 1.0 cm gypsum interior plaster, 17.5 cm hollow brick, 10.0 cm ETICS, as well as 1.5 cm synthetic resin plaster. Both variants have a U-value of 0.23 W/m²K.[/QUOTE]

Ignoring the HVAC for now.

Overall construction of all windows with triple glazing U-value 1.1 (measured over everything and not just the glass, as is often the case in competitions), technology: air-water heat pump with integrated domestic hot water supply and 300 l hot water storage tank

The calculated annual primary energy demand QP amounts to 55.15 kWh/(m2 a) and thus meets the minimum requirement of at most 70% of the calculated maximum value for the reference building according to Table 1 of Annex 1 of the Energy Saving Ordinance 2009 of 89.24 kWh/(m2 a). Furthermore, the transmission heat loss HT’ related to the thermally relevant envelope surface amounts to 0.26 W/(m2 K). At the same time, the maximum value of the transmission heat loss HT’ specified in Table 2 of Annex 1 of the Energy Saving Ordinance 2009 of 0.45 W/(m2 K) [I](please enter value) is not exceeded.[/I]

There are also only a few who can really plan and implement cleanly with aerated concrete or Poroton.

We have been working with this material for over 22 years; I may assume my colleagues are experienced.

Much requires special solutions, which also have their price.

That may apply to the small contractor with limited purchasing options, although I have already experienced the occasional unpleasant surprise regarding the calculated number in offers in this area; it appears that for the small contractor the thickness of his order book determines the final price. I have come across competitive offers from such calculating contractors that were sometimes up to EUR 30,000 below my offer with allegedly the same or even better equipment. +/- EUR 5,000–10,000 is normal with comparable equipment.

Thermal bridges are created far too quickly, or the load capacity limit is reached.

There are manufacturer-related thermal bridge catalogs for that ;) However, I am convinced that our specialists have the proper training. And a structural engineer—based on all experience—does not simply sign off on incomplete calculations.

Also, there is no masonry through which cracks can form more quickly.

Mostly due to rigid or erroneously executed connections = defect. How apt that possible cracks remain hidden behind ETICS facades ;) I have worked with Liapor, sand-lime brick, hollow brick, and aerated concrete and do not know a single-family house that did not develop hairline cracks.

Kind regards

Hello,

Yes, that would be a possibility, although at the moment we could have bought a plot of land cheaply. That will not be the case so quickly in the future, at least not for €85/sqm.

You should not assume that as a given. According to all knowledge, the municipal coffers are empty everywhere, which is why the municipalities are selling their silverware (properties). There will be cheap building land for years to come – relative to private sellers – so there is plenty of time to save equity.

Kind regards
