Psi-Value Competency Scheme

Elmhurst Energy's Psi-Value (ψ-value) Competency Scheme provides a great opportunity for SAP assessors and those involved in the building process to become industry recognised as Psi-Value Modellers.

A combination of high quality training and thorough assessment has been developed in order to ensure individuals can undertake Psi-value calculations in accordance with BR 497 standards, as well as 2D and 3D thermal bridging calculations for junctions, within SAP and SBEM.

Why become a Psi-Value Modeller? 

As a Psi-Value Modeller you will no longer need to rely on prescribed junction details and will have the ability to model bespoke or unusual junction details, using the resulting psi values within your SAP and SBEM assessments. Modelling Psi-values will also give you greater flexibility when trying to achieve compliance with Part L regulations.
