Become a Thermal Bridging Expert
Thermal bridges need to be assessed and calculated separately with a thermal bridging simulation software, before their values are entered in the PHPP.
In this course you will learn everything you must know about thermal bridge calculations – from the theory to practice. You will acquire in-depth knowledge – what boundary conditions should be used, methodologies, how to calculate different types of thermal bridges, for example external wall to floor connections, window installations, many more, and how to minimize heat losses.

Proven professional process
A step-by-step process that will enable you to master thermal bridge calculations.
Real world examples and actionable advice
Explore common junction details and effective modeling practices.
In-depth feedback from industry experts
Hone your Passive House skills with feedback from the PHS experts.

What our course participants say about the course:

Laura Boffardi
Passivhaus Designer - ECD Architects
Excellent!
Initially I was a bit reluctant and worries about the video lessons but then it proved to be a successful methodology because you can rewatch them any time you need. Plus, Anton is always available for a clarification. The speed he replied and the care he placed in the answers to our doubt was wonderful.
I felt supported and encouraged till the day of the exam. I am glad I chose them. Also because I can feel the passion they have for Passivhaus.

Patrycja Kochaniuk
