ᐅ How can you bypass energy-saving regulations and avoid bureaucratic hassle?

Created on: 8 Jul 2017 19:26

Hello everyone,

Is it possible to build without following the energy saving regulations?
I want to avoid unnecessary insulation and similar measures. At the same time, I want to maintain the great indoor climate that exists in this building from 1959.
Although it was barely insulated, the house remains completely dry and the indoor climate is excellent.

I am planning to build an extension that fits this outstanding indoor climate. All these modern insulation methods are not helpful in this case.

Does anyone have some kind of exemption from the energy saving regulation and can share how they obtained it?

Thanks in advance.
Best regards

Here is an on-topic question again:

Is there a way to meet the Energy Saving Ordinance standard by using a double-layer masonry wall (calcium silicate bricks) with just an air cavity in between? In other words, without filling this air cavity with any insulation? Additionally, the roof would be insulated with cellulose accordingly.
I would choose double-glazed windows.

I am not aiming to achieve KfW standard, just to barely meet the Energy Saving Ordinance guidelines (or possibly obtain an exemption/approval, but I am already looking into that in parallel).

You can also use pumice blocks, which are basically lightweight concrete (aerated concrete) as well, but the aeration is achieved by adding pumice.

Pumice blocks are cement-based blocks with pumice as the main component. Pumice itself does not have any foaming effect; it is a naturally stable volcanic rock that has existed for a very long time.

Lumpi is right. It’s not enough. A cavity wall can be built with 24cm (9.5 inches) Ytong or similar Poroton blocks, then a layer of mineral wool insulation in front, and then the facing brick. With calcium silicate bricks, the insulation needs to be thicker because the brick has poor insulation properties due to insufficient air content.

Hi Lumpi,
Hi Nordlys,

Lumpi is right. That’s not enough. A double-wall construction works with 24cm (10 inches) Ytong or similar Poroton blocks, then a layer of mineral wool insulation, and the brickwork on the outside. With sand-lime bricks, the insulation needs to be thicker because the stone has low thermal insulation and contains too little air.

Hmm, okay.
Mineral wool... What is the current understanding with respect to health concerns?
As a child, I was always told that mineral wool caused cancer (at least during installation).
But surely there must be more recent and detailed findings on this, right?! I’ll do some googling... (Although with Google, everything seems to be carcinogenic if you search hard enough.)

Do you happen to have a reliable link on this?

Why not build yourself an eco-friendly house?

As mentioned somewhere, wood fiber is also available as wall insulation. Cellulose is then used for the roof.
It only gets interesting with windows and the insulation under the screed (for the extension). I don’t know of any natural materials for these areas.
