Hello everyone,
Our single-family house construction is starting in September.
We have already chosen a structural brick with a thickness of 36.5 cm (14.4 inches).
Now we need to decide which specific type of brick to use. The main question is about thermal insulation versus soundproofing. Of course, good insulation is important, but I’m concerned that the house might become very echoey with a T9 brick.
The second question is whether anyone has any calculations or data on how much heating cost can be saved with a better brick, or how much more you pay with a lower-quality brick?
I would be very grateful for any answers!
Thank you very much.

Hello,
and exactly here:
lies the entire problem of the energy transition: solar and wind energy do not make us any less dependent on fossil fuels. They simply cannot; the average politician and eco-activist intellectually fail to recognize this.
All conventional power plant capacity must continue to be fully maintained and runs very inefficiently. After all, there will also be windless winter nights. There is no sun or wind then, but everyone wants their heat pump running.
Heat pumps in particular are absolutely dependent on fossil energy! When these devices are needed most, we have the “dirtiest” electricity. *argh*
On a calm winter night, you can choose whether to run the heat pumps on electricity from coal or nuclear power from France, there simply is no alternative!!! How is that supposed to be environmentally friendly?
Best regards,
Andreas

the government's goal is to become more independent from fossil fuels – partly for political reasons and partly for environmental concerns.

No, Bauexperte,
you are mistaken here.
Unfortunately, that is incorrect. Quite simply, there are no energy storage technologies available that can provide sufficient amounts of electricity. Not even for a few hours, let alone several consecutive windless winter days! And this is not because some stubborn people refuse to do so, but because physics simply does not allow it! There is not enough lithium in the world to have large batteries in every house, not enough platinum to convert power to gas and back to power via electrolysis everywhere.
Apart from that, battery production is far from environmentally friendly. Why do you think most of them come from China????
A country like Norway could use pumped-storage hydroelectric power plants, but we cannot, and at the few potential sites for hydropower plants here, you immediately have environmental activists protesting because a frog/field hamster/whatever would lose its habitat. Besides that, you still need power lines—quite a sensitive topic.
It is true that the big electricity companies completely missed the future. Relying on nuclear power plants and coal subsidies was just more comfortable. It didn’t require any thinking...
Now they are rightly going downhill!
But to say they don’t invest in storage technologies out of laziness is wrong, because none exist!!!! Quite simply, there is no storage technology that could supply an entire country!
And yes, it is true that on a nice, sunny, and windy day, our country can cover all or nearly all of its electricity from renewables. But that is not the challenge we are talking about!
As long as people are not willing to accept that, in a worst-case scenario, electricity and thus heating may fail for a week in winter, the complete energy transition will not work. And I am NOT willing to accept that!
Best regards,
Andreas
you are mistaken here.

In my opinion, this is because they simply do not want to recognize the opportunities for themselves, prefer to lament over old privileges, and therefore still do not want to invest in storage technologies.
Last Sunday, photovoltaic and wind power plants temporarily covered 87.5% of Germany’s electricity demand.

I seem to remember that there are now alternatives to platinum as a catalyst—at least in research. I also believe that the lithium battery will not be the final step; perhaps other molecules will eventually be used in batteries as well. I think this field is exciting and one of the major trends for the next 10 years. Governments are currently creating huge demand for new technologies—which isn’t a bad move in capitalism... money is practically shouting out and pushing itself onto anyone who can find the answer.

What I do know is that just last year, a research team succeeded in improving the energy density of lithium-ion batteries; meaning, their storage capacity has increased.
That’s why I’m convinced that—as long as power producers invest money in research—it will eventually be possible to develop short-, medium-, and long-term energy storage. And who knows—it wouldn’t be the first time that a so-called side result opens up new possibilities.
One small PS: most batteries still come from China because they are (currently) cheaper, and people’s environmental awareness often ends when it comes to their own wallets.

Oh, the entire energy transition is one big web of lies that can make you feel sick.
The end product, electricity, is supposed to be clean, but first, it exploits virtually all the world’s resources.
Where does lithium come from? Exactly... from lakes in Bolivia, Tibet, and so on. And how is it extracted? I recommend looking that up... It’s not like batteries don’t also contain toxic chemicals like battery acid...
We’re just shifting the problem. How will all the batteries, considered hazardous waste, be disposed of in the future?
And how will we power the millions of heat pumps connected to the grid that consume electricity and make grid management so complex that coal and natural gas power plants are still needed to balance the load? Especially in winter, when heat pumps basically become electric heaters and you could just heat your house with a simple fan heater plugged into the socket...
But yes... in the glossy brochures of the heat pump lobby and within the circles of the government, the energy transition is, of course, a move toward more conscious use of electricity, fossil fuels, CO2, and resources... *cough*
The only somewhat green electricity is the one generated from your own rooftop! Only, in winter the sun shines far too rarely and storage capacity is just not sufficient... oh, and we also have the battery problem again...
No matter how you look at it: moving away from fossil fuels only shifts problems and planet exploitation to another place. Electricity has never been green and never will be, no matter the technology used to produce it.
Photovoltaic modules have a devastating carbon footprint during production, but everyone claims they’re so green. The same goes for heat pumps.
But we keep convincing ourselves and practicing eco-fascism based on dangerous half-knowledge and willful blindness.
And in China, India, and on the world’s oceans, they continue to release pollution unfiltered into the atmosphere – while the “ordinary person” here must follow eco-dictates, pay dearly for it, and watch other countries buy their way out of environmental problems and freely dump pure poison into the world.
