Advanced Thermal Bridge Calculations - online course

Modelling a thermal bridge in THERM, Flixo or some other 2D heat flow tool is relatively easy; understanding when there is a need to model, what to draw and how to quantitatively interpret the results requires more experience.

This course for people with pre-existing exposure to thermal bridge modelling and the Passive House Planning Package (PHPP) is a significant stepping stone on the journey.

What we will cover

Understanding when you need to model:

  • Understanding of the typical ranges of thermal bridge coefficients for assemblies.
  • Does a connection detail require accounting for thermal bridges?
  • Can I use an atlas/catalogue to find the Ψ-value, or do I need to use software to find it?

Understanding what to draw:

  • The thermal bridge concept and understanding of the outputs available from a heat flow calculation.
  • How to set up a thermal bridge calculation for specific connection details; PHI and PHPP fundamental concepts you need to understand for window connections and ground connection details.
  • The standards used for thermal bridge calculations and what you should know about them.
  • Ψ-values and fRsi values what are the correct boundary conditions to be used. fRsi limits and changes in PHPP 10.

Working with worksheets calculating Ψ-values and fRsi values from details with known dimensions, component qualities and heat flow results will be part of the programme.

You will receive a printable copy of the lecture slides, and instructions for further learning in your own time. Registrations need to be received before 10 September 2020 to allow for course preparation on the online learning platform.
