PSI Value Calculations

Calculate PSI values to help eliminate risks of cold bridging and boost your SAP calculations. 

About

PSI values represent the heat lost at junctions between various plane building elements e.g. walls, roofs and floors. Where higher heat flows occur in these areas these can create localised reductions in internal surface temperatures which can lead to surface condensation and issues with mould growth.  

Why Choose AES?

Market-Leading Software for PSI Value Modelling

Using advanced software our team are capable of modelling both 2D and 3D Psi Values ensuring the majority of junctions can be calculated.  

National Coverage

We offer PSI Value calculations nationwide, providing expert thermal bridging assessments to improve energy efficiency and compliance across the UK.

Improved SAP Ratings & SBEM Calculations

Using independently calculated PSI Values within your assessments, in lieu of default values, we can enhance your building’s energy performance and help optimise your build specification.  

Cost-Effective and Risk-Managed Solutions

Where necessary our experts will advise on how to better improve thermal performance at junctions and advise as how to reduce risks of encountering issues with mould growth in future.  

PSI Value Calculations With AES

We use market-leading software here at AES capable of modelling both 2-dimensional and 3-dimensional PSI values allowing us to calculate a wide variety of different junctions. Our assessors evaluate the heat flow through the junction and determine internal surface temperatures to identify where a potential risk of internal surface condensation or mould growth may occur.  

Wherever possible our assessors will use their vast experience to review details prior to calculation to help identify any likely issues early and advise on where improvements could be sought prior to calculation.
