A recent Standards Council of Canada webinar on the new National Standard of Canada, Thermosyphon foundations for buildings in permafrost regions, is now available for viewing online.
The webinar introduces the main elements of the new standard, including:
- site characterization
What are thermosyphons?
Thermosyphons are heat-transfer devices that work to draw heat out of the ground and out into the air. The warmth of the ground causes the liquid contained in the thermosyphon tubes to evaporate into gas, which then rises to the top of a tube, where the heat the gas carries is dissipated into the air. This helps preserve the integrity of the permafrost on which many buildings in the North are constructed.
By keeping the ground underneath important community infrastructure stable, and reducing the need for costly repairs, thermosyphons offer a low-tech solution to help those living in Canada’s North.
