  • Does this training meet the competency requirements of BR497?
    As of 2016, the BR497 exercises are no longer intended to act as a means of proving competence. They are useful for individuals to highlight for their own benefit where they need to improve their modelling abilities. Our course is designed to be an introduction to calculating Psi-values and therefore does not exhaustively cover every type of junction that may arise, but we believe that, having completed it, you will be in a position to complete the BR497 exercises and obtain the correct results.
  • Does this training mean I will be a "competent assessor" of thermal bridges, for SAP purposes?
    There is no mandated definition that we have yet seen of what a "competent assessor" is, but would suggest that completing the BR497 exercises correctly would suggest a level of competency.
  • Is the course accredited by the BRE/any Government scheme/other?
    No, we are not aware of any body that approves training schemes for thermal bridge modelling. We can provide you with a statement saying that you have completed the exercises in the course.
