What you'll learn

This short course will teach you how to improve the energy performance of your buildings by learning how to identify and model 2D thermal bridges and calculate Psi-values.You'll learn skills that you will also be able to apply to more complicated situations once you've mastered the exercises in this course.

We use THERM software as a medium to teach the concepts of thermal bridging calculations because it is free to download and use. Upon course completion, you may wish to explore alternatives to THERM - although the interfaces will vary, your understanding of this software package means you will easily be able to learn how to use others.

By the end of the course you will be able to

  1. Understand why thermal bridges are significant.
  2. Explore how thermal bridges can vary in construction.
  3. Understand the concepts of calculation for 2D thermal bridges.
  4. Calculate 2D thermal bridges using THERM software.
