How can one circumvent the Energy Saving Ordinance and avoid bureaucratic madness?

As written somewhere, there is also wood fiber as wall insulation. Cellulose then goes on the roof. It only becomes interesting with windows and insulation under the screed (for the extension). Here I do not know of any natural materials. Regards Joe

Hi,

I don’t understand all this writing here anymore. Take a 36 cm aerated concrete block or a 36* cm Poroton. With both you have a monolithic wall structure. With both you can easily meet the Energy Saving Ordinance requirements; both are ecologically harmless stones and that’s that.

You don’t need to put plastic in front. For the windows, I would choose triple glazing; they are significantly better in terms of insulation WITHOUT bringing chemicals into the house, and the additional costs are also limited since triple glazing is basically standard nowadays. And since you want eco anyway, you’ll get wood or aluminum windows which are a whole lot more expensive anyway, so the glass price hardly matters anymore.

For old buildings, I would at most insulate the roof; everything else is not economical.

And all the other blah blah with red/blue/morning/evening is pointless anyway. The heat input from the sun when you need it is not sufficient (winter). This applies both to solar thermal and photovoltaics. Hardly any yield in winter.

You don't need to put plastic in front of it.

Well, that's probably the question. The mind doesn't want to "put plastic in front," yet processes the "plastic" during Poroton manufacturing. What was gained by that? But that's the big game in the topic of "ecological" building; it's a matter of definition and limited by budgets. Ask a Poroton seller about the ecological factor, and they'll tell you anything but that Styrofoam was baked in; they'd rather babble about clay and breathable walls. Everyone does that for their product. It doesn't help him either if the Poroton is transported across the country while the sand-lime brick is produced in the neighboring town. Is the Poroton then really "ecologically harmless"?

Well, that’s probably the question. The mind doesn’t want to "put plastic in front," but it does process the "plastic" during the production of Poroton. What has been gained from that? But that’s the big game when it comes to "ecological" building,

Porous bricks and natural products are as "identical" as "organic" and "organic label"

But maybe this thread will still manage to "drift" to the factual level, e.g., by the original poster bringing the specific old building into the discussion so that we even know what kind of extension we are talking about. Because I really don’t think much of ignoring the existing building and its construction when extending. And there have actually been enough changes of "religious" convictions. In the seminar about the right timing for thermal imaging, I kind of lost track in terms of interest...

Actually, I didn’t want to get involved in this nonsense here, but maybe there is one or the other who is actually looking for historical construction methods. Here in Radebeul, there is the company Villa Belavista. They offer new builds directly in the old style. However, they state right on the homepage that cheap materials and wage dumping are not an issue for them – which presumably is meant to immediately deter the wrong clientele. I once sent them an email – no response. Now you know.

Mind you: style. Technically, this does not in the least mean that it was handcrafted by grandma according to an old recipe. A visual spice mix, just a different flavor than "Bauhaus" or "Tuscany".
