Thermal Engineering

Supporting sustainability and green building practices

Our thermal services group works with architects, mechanical engineers, and owners to evaluate the feasibility of utilizing ground source heating systems at their sites and developing thermal properties for design so they can make informed design decisions on their projects. Examples include:

  • Ground source heat pumps and geo-exchange heating and cooling systems
  • Energy piles and thermos-active foundations


We evaluate thermal properties of the ground for these projects in our laboratory and in the field using full-scale Formation Thermal Conductivity Tests.

Through thermal simulation numerical modeling, we assess how underground heat transfer impacts foundations, structures, and natural systems. We measure thermal properties of soil, rock, concrete and other construction materials in our laboratory using a needle probe. In the field, we install and monitor in situ thermal instrumentation to evaluate heat flow and temperature conditions and use this information to guide our engineering analyses and assess risks to our clients.

services INCLUDE:

  • Arctic foundations
  • Passive refrigeration ground improvement in cold regions
  • Buried power transmission lines
  • Thermally-sensitive structures or features
