Hello, I happened to notice that a new office building in our neighborhood is getting an exterior plaster with integrated solar technology.

Does anyone know about this? Is it suitable for individual residential use, or are the costs and benefits not justified?

Unfortunately, I pass the construction site every morning and evening when it is not staffed.

Thank you,
Hilaria

As far as I know, this is a plaster that works with very fine "ceramic hollow spheres," roughly comparable to expanded clay systems. The base coat, finish coat, and paint are coordinated and all come from the same supplier. I seem to recall that this system has been on the market for about three years and is only distributed by a single provider in the eastern part of the country—the patent holder.

I can’t provide an exact price, but I assume it is about 30-40% more expensive than a standard finish coat (patented products sold exclusively by one supplier usually carry a premium) and is therefore mostly used in office buildings so far. I’m not even sure if this plaster is accounted for in energy performance calculations—but that should be something the €uro can answer.

Best regards

Thank you for the quick response.
When I search for solar plaster on Google, the first result is the solar plaster used in my neighborhood.
It comes directly from our region and also from my old home area, but I cannot determine who holds the patent.
Unfortunately, there is no information about its application, whether it is used only for large buildings and/or individual houses.

Regards,

Hello construction expert, I have now found that the additional costs for a single-family house are around 800 euros. Can you say what the exterior plastering of a single-family house generally costs, or how much this is expressed as a percentage?

But what is the point of that? With a thickness of just a few millimeters (inches), it will never provide effective insulation for the house!

Hmm... €800 in additional costs would probably – in my opinion – only cover the final coat? Otherwise, it would indeed be cheaper than a render with a lotus effect and thus certainly more affordable than I had expected.

No, the costs cannot be easily defined in a universally valid way because every house has different dimensions, possibly setbacks, etc.; regional differences as well as possible mixed calculations must also be taken into account.

You will get the best sense of the proportional costs if you ask your supplier about the surcharge for a full solar render.
