Research Abstract 

Project intends to model and design heat transfer systems for the new technology called inter-seasonal heat/cold transfer, to stabilize permafrost and increase resilience of buildings and infrastructure against permafrost degradation and weather extremes or thaw permafrost before construction. Mathematical modelling of inter-seasonal heat/cold transfer based on collected field data combined with historical data will provide direct and reliable methodology for capturing surplus cold in the winter and storing it in the ground using phase change material or soils. This heat (cold) could be released in summer to reduce costs repairs and maintenance of buildings or infrastructure. Another application of inter-seasonal heat/cold technology is to prevent permafrost degradation and stabilize thawing ice –rich permafrost.

Salary: $446 to $994 per week (37.5 hrs). Masters level – $754 to $892 per week depending on the number of completed semesters.
