Construction costs are currently skyrocketing

The appropriate keyword is "humus formation". Without it, forests bind only a fraction of the CO2. Waste wood is at least as important as the trees and should therefore definitely not be burned.

It is probably more sensible not to clean up the forests clinically. After the machines have caused significant damage during logging, should machines go back into the forest to reintroduce sawdust, trimmings, etc.?

Either change the title here - or finally get back to topic. Otherwise, the moderators aren't that sensitive either....

So I worked a bit on my barn today. It was built 200 years ago from self-supporting clay walls. And as long as there were no water damages, they still stand today like on the first day. The walls are almost one meter thick. Due to wind, rain, etc., since it is not plastered, the wall naturally wears away by 2 - 3 cm over 100 years.

There were a few damaged spots. In one corner, there were still some remnants of another wall. So some clay into a bucket, mixed with some straw and water. Mixed well with the whisk until it became a thick mass. Then it can be processed. Almost like concrete mortar.

And it costs nothing. It has been lying in the corner for 20 years and can be reactivated at any time. The material itself is now 200 years old and still as fresh as on the first day. It is easy to work with and a lot of fun.

That is sustainable. That is resource-conserving.

Either change the title here - or finally get back to topic.

There is a connection between construction prices and sustainability efforts for climate protection. Not least because of energy-saving efforts in operation, construction costs have risen sharply in recent years. This is certainly not a single cause but definitely a factor. Looking ahead, construction prices will receive another boost as CO2 emissions will consistently be assigned a price. This directly affects building materials such as concrete, for example. You may find this annoying or not - for many, it simply belongs to it.

I also think that the topics of climate protection and construction costs are inevitably connected. Many (and this can be seen in current threads) are asking themselves whether they should install gas or a heat pump in the new building.

An acquaintance will build next year with the same BU as we did in 2019. The heating including installation is 20% more expensive. Roof structure and carport (with wooden roof) about 10%. Strangely, there is no "surcharge" for the insulation. The location is central Hesse.

Construction prices have increased by 20% in the last two years, for example. Then climate protection has only played a minor role in this 20% increase. The relevant factors were: -disproportionate demand (also due to Corona, the desire for one’s own four walls or own garden, etc.) -on the other hand, general contractors with already full order books who remain fully booked despite price increases -shortage of craftsmen -raw material delivery problems and material price increases -land prices We tendered and awarded contracts ourselves in 2017-2018. Even then, it was not possible to negotiate due to full order books. But at least one received 4 offers out of 5 inquiries. And then one could still choose with whom to work. Today I have the feeling (from reports here in the construction area or friends and colleagues) that one gets a maximum of 1 offer out of 5 inquiries and almost has to accept it at any price, otherwise someone else takes it. Can someone who is currently building on their own / requesting offers report? How many offers from how many inquiries?
