What is the relationship between the wood structure of traditional houses in northern Europe and the climate?

Most of northern Europe belongs to the sub-frigid coniferous forest climate, and also belongs to the temperate continental climate in a broad sense.

Northern Europe is influenced by polar ocean air mass and polar continental air mass. Winter is long and cold, summer is short and warm, relative humidity is high, and the temperature is high all year round. In some extreme areas, the annual temperature difference even reaches 65℃.

Wood is an excellent heat insulation material, which can effectively block the heat transfer. The wooden house is warm in winter and cool in summer, which is very suitable for the climate in northern Europe.
