Integrates indigenous Sami and Inuit knowledge: wooden piles driven in frozen ground develop an "adfreeze bond" that vanishes upon thaw. The guidelines introduce based on mean annual ground temperature, not air temperature. For warm permafrost (0°C to -1°C), local practice of using thermosyphons is now a prescriptive requirement.
