I just came back from a trip to Denmark, where I visited the Frilandsmuseet, an outdoor “museum” collection of traditional buildings from all over Denmark and Sweden.
Here is a photo of a “concrete-free” foundation which I thought you all might enjoy. I wonder how much embodied carbon there is in a structure like this, compared to how much protection it offers from the elements. Granted, it’s not as much protection as a home built to Passivhaus standards. But considering the means available to people at that time I’ll bet it’s very efficient, as far as it goes. I’m sure none of the materials came from more than a few miles of the construction site. The one fault was that trees were not replanted to replace those taken from the primeval forests.
Have a great weekend!
