Our project looked at climate neutrality 🇩🇪 2045.
Buildings built in '25 have an operational greenhouse gas emission budget of 6.86 kg CO2e/(m²*a) + embodied 6.41 kg CO2e/(m²*a).
By 2045, these budgets will be reduced to 1.05 and 0.79 kg CO2e/(m²*a), respectively.

The latter means that you assume biobased materials are burned/ won't last 50 years. And mineral products last forever (Which is nonsensical).

There are numerous lobby studies disguised as scientific works that discredit renewable materials in favor of mineral /synthetic business as usual construction. One strategy is to compare the worst timber product with the best unicorn mineral products. And of course play with the End of Life stage.
MISLEADING: A new academic paper by @qmul.bsky.social has attracted significant media attention by claiming that EVs & heat pumps deliver no proven carbon savings in UK ahead of 2030 clean power target - and should therefore be postponed.
Here is why this paper should never have been published.🧵

Our task as humanity is to achieve lower energy demand without fossil fuels. As well as reducing resourcevextraction / consumption, reaching a circular sufficient economy. However, the response of high-tech companies is always to build additional structures.
Find the mistake.

#TaxTheRich we need more common sense, common like in commons. AI enterprises base their profits on common knowledge, public infrastructure & destroying common wealth (climate, water consumption, causing pollution through mining…) not paying back. That’s backlash in early Industrial Revolution.
650 billion this year?
In the midst of a climate crisis and the sixth mass extinction, it should be the bare minimum of responsibility to build data centers climate-neutral. This applies not only to their operation, of course, but also to their construction.

I think what people miss is that straw panels are so much more modern and efficient (in operation and production) already than most high emission - standard building methods👋

Ok.. 😄 I was actually talking about using this / or rather a future non-decorative product as an external wind tightness layer. A paper would be sufficient but a clay-paper would be better to reduce fire risk.

Yes a paper would not hurt, as well as a quick clay slip spray maybe, ... There is also clay tapestry that would be quite good.

Likely not as performant as with proper windtightness but a conversation starter.

"Although larch formwork is not windproof & does not provide 100% protection against driving rain, in practice it proved to be unproblematic to clamp the ST hemp filler directly behind the larch formwork.
In special situations, not on the coast, not in moorland, rear ventilation is not necessary."

back on topic, atm this is my favorite to upgrade the exhibition piece. It's hemp wool, hand stuffed, maybe larch facade directly without vented space, just to have this conversation. :-) hanffaser.de/index.php/ho...

Time for something real. Photosynthesis. Boring?
It takes 100-200 billion tons of carbon annually and turns it into approximately 450 billion tons of biomass.
Renewable. Enough for everyone to eat + live on. If you don't burn it, also sustainable.

With the amount/ type of products there, I'd say no. This needs an atheistic approach for resilience if there are biobased products in the assembly. I do wonder if this can be cheap with so many products. We do have examples were biobased materials did not work as modeled with so many layers.

The findings are going against the grain of all published research known to me. That being said I am more than interested to know more about the case. I did forward the issue to the german straw bale building association at the time.

I like a good discussion!
Regarding the Fraunhofer IRB & their straw test with the following anecdotal communication...
We had this discussion when I quit Twitter. I was present when the results were communicated. In my opinion this was either a pre-infested bale (logistics) or a really bad detail.

In principle I am open to use the bad stuff where it makes sense, but it must be a recycling/reuse product.
In our house I prepared some infrastructure for these experiments with trombe walls etc but did not use it yet.
