Introduction to THERM Workshop

Take On Thermal Bridging Like a Pro

The best thermal bridge is one that doesn't exist. But let's face it – sometimes they're unavoidable. Passive building design emphasizes the importance of the thermal enclosure and encourages continuous insulation at all junctions in the enclosure. If a connection detail does not have continuous insulation, the linear heat loss at that connection should be quantified via modeling and calculation. This process can be used to iterate and minimize loss at tricky connection points and to quantify the linear heat transfer coefficient for whole building energy modeling.

Course Structure

Hands-On Virtual Learning

The course is 10 hours long in total, spread over 3 days of live instruction in one week. It will be made up of live presentations, instructor-led tutorials through the software where students are encouraged to follow along, and group workshop sessions for students to review and analyze results for pre-calculated details and gear up to calculate their own details.

Gear Up for Phius Certification

Students learn fundamentals of thermal bridges, how and why they’re calculated, be able to quantify the linear heat transfer at component connection details, analyze those results, iterate to improve the detail, and create a thermal bridge report that could be used in a Phius Project Certification submission.

Troubleshoot, Troubleshoot, Troubleshoot

In this course, after learning the fundamentals, students are provided with and apply a step-by-step guide to review and troubleshoot calculated details, ensuring that each student is equipped with the tools needed to be confident with the results.

THERM is a Powerful Tool

THERM is a two-dimensional heat transfer model used to assess the thermal performance of building components and connections between building components. It can also be used to analyze risk of condensation or mold growth on an interior surface at a thermally bridge condition. This course will provide students with the tools needed to assess for moisture risk at tricky details in both the opaque enclosure and for fenestration.

Key Course Takeaways

  • Understand the fundamentals of thermal bridge analysis.
  • Learn how to navigate the THERM software, recognizing the full functionality and assessment methods that can be utilized.

The Software

The tool itself is downloadable for free online. A download link will be provided upon registration to the class. If you already have the software, be sure to check course materials to ensure your version is appropriate for the course.



No previous training is required. Background knowledge on thermal bridging and thermal bridge modeling is recommended but also provided at no cost as supplemental pre-course materials for students.
