Using Heat3 for Thermal Bridge Modelling

Acquire the 3D thermal bridge modelling skills that will help you stay up to speed with evolving building energy codes

Upcoming: Certified Passive House Designer Course

Jan 16

In this 6-week online course, participants will learn the fundamentals of thermal bridging calculations and examine modelling conventions for common 2D and 3D details. Modelling techniques will be taught using Heat3.

Heat3 is a 3D thermal modelling tool that lets users calculate the impact of 3D thermal bridges. The tool is gradually becoming the standard tool used for calculating thermal will thus be an invaluable tool for building energy modellers and envelope consultants to understand.

What our students are saying about our courses

The Heat 3 training course provided by Peel Passive House was very well presented and organized. The lessons were all supported with hands-on exercises that helped to ensure that I was able to apply what I had learned. The student resources provided by Peel Passive House included a number of files that will be very useful to me going forward.


"Andrew's training in Heat3 provided our firm with a strong knowledge base of the software and its capabilities. He took this one step further by walking through real time examples of 3D thermal bridges; allowing us to familiarize ourselves with the software's intricacies that we now work with on a day-to-day basis. Andrew's knowledge of thermal bridge modeling is first-rate, and I highly recommmend him to anyone interested in his training courses."


"The training session provided by Andrew Peel to our group of technical specialists was well organized, thorough, and directly focused to our practice. Andrew exceeded our expectations and we look forward to working with him again in the future"
