Therm On-Demand

Learn the fundamentals of thermal bridging calculations for wood-framed construction.

Upcoming: Certified Passive House Designer Course

Jan 16

Thermal bridging is an important consideration in Low Energy Building design. Generally, the aim is to wrap the entire thermal envelope in a blanket of insulation, thereby eliminating all bridges. However, practicalities and cost may prevent this goal from being achieved. To properly assess junctions that contain thermal bridging, 2D thermal modelling is often needed. This modelling must be carefully performed using validated software to ensure accurate results.

In this course, participants will learn the fundamentals of thermal bridging calculations for wood-framed construction. Common junction details and their modelling conventions will be examined. Modelling techniques will be taught using Therm. Participants will be given the opportunity to perform calculations with in-course exercises. Support for participants is offered via posting in the chat section for each video for the Course.

      Learning objectives

      1. Gain better understanding of heat loss in buildings due to thermal bridging
      2. Understand what comprises a high quality junction detail
      3. Learn basic commands in the steady state numerical analysis software THERM
      4. Create 2D thermal models of junction details
      5. Learn and apply the Passive House thermal bridging modelling conventions
      6. Gain practical experience in the calculation of thermal bridging heat loss
      7. Account for thermal bridging in building energy modelling software

      Ideal for:

      Building energy modellers, building envelope consultants, engineers, architects and other building professionals that wish to understand and quantify thermal bridging.

      This course is a good fit if:

      • You want a tool that will streamline your Passive House energy modelling  
      • You want to explore the energy performance of early design options without committing a significant amount of time and resources to energy modelling
      • You would like to spend more time modelling and less time doing takeoffs
      • You need a tool that will help you effectively document your modelling work for Passive House certification

      What our students are saying about our courses

      Peel Passive House is where I took my CPHC/D course and exam. The PPH crew is awesome, the cumulative knowledge and experience is legit. 10/10 would recommend to a friend, or my Mum if she ever decided to take a weirdly sharp turn in occupational direction.

      I do not come from an educational AEC or engineering background. Being self taught when it comes to building physics and energy modelling; Andrew and Melissa's course was presented in a way that was easy to understand and digest, LOTS of visual data and very effective means of sorting and annotating material that helps maximize the learning from every slide. Andrew Peel is a fountain of knowledge when it comes to Passive House and my only regret is that due to Geography I was not able to take the course in person.


      A great team to work with and learnfrom!


      Thanks to Peel Passive House ConsultingLtd. for a fantastic course and compiling an extensive curriculum that goes above and beyond not just preparing you for the exam, but fully inculcating the intricacies of the underlying scientific concepts.


      Andrew walked us through the various aspects of PH from start to finish in a very organized manner. His practical experienced gave us great insight into how the various PH principles can be implemented and the challenges that go along with them. No course is going to turn you into a PH specialist, but this sets you up nicely to get into the industry to become one!
