Insights and performance analytics.
- How detailed of a report can we generate from AutoPSI?Let's break down what your AutoPSI report contains, using a typical external wall corner as an example.
- Can I add our logo and company information to the report?Customize your report
- Why is the U-Value for PSI Value Calculations Different from a Typical U-Value?
- What are the essential metrics I need to report?AutoPSI is designed to calculate two key performance metrics that are essential for assessing and mitigating the impact of thermal bridges: the Psi-value (Ψ) and the temperature factor (fRsi).
- How many decimal places should I use for my results?Reporting your calculation results
- What happens if my calculation results are disputed?Reporting your calculation results
- Condensation Risk: fRSI vs. Dew Point in Thermal Modelling ReportFor architects, consultants, and builders, correctly assessing the risk of moisture-related issues is crucial. Our thermal modelling software, AutoPSI, is a powerful tool for this purpose, primarily by calculating the…

- Do you provide training and certification for Elmhurst Energy accreditation?
- Do you offer technical support?
- When is the next 2D competency training course scheduled?
- I have projects that require Thermal Bridging details now. Can I start training sooner?
- What is the certification requirement for Thermal Modelling?
- Do you provide training?
- Will my reports from AutoPSI be suitable for audit?
- About AutoPSI
- Using AutoPSI Calculations for SAP SubmissionsUnderstand the compliance standards and validity of AutoPSI Psi-values for formal SAP assessments.
- Why does the same junction give a different Psi value in Quick Draw and Free Draw?Bridges don't transfer when a junction is converted to Free Draw, and layer misalignment creates a phantom cold spot — re-add bridges and align layers so the two methods match.
- Will TrustMark accept my report, and why don't modelled bridges appear on the material list?Short answer: this is expected behaviour, and your model is still correct and compliant.
