Psi-Therm 3D

Our Psi-Therm software is the leading Finite Element Mesh analysis tool available for the analysis of thermal bridges in construction components. This powerful design tool is validated to ISO 10211, with automatic mesh generation in order to ensure accurate results in accordance with ISO 10211. Exclusively available to Passivate customers, the software now comes with a boundary condition database for analysis according to BR497 and Passive House  conventions. Saving you the need for complicated spreadsheets and numerous external calculations, the software produces U-values, Psi-values and Frsi-values, producing a comprehensive report in accordance with the requirements of the international standards.

NEW IN VERSION 2016

See the list below of further improvements to our powerful 3D analysis software

  • Brand new snap/cross-hair tool allows much more precise input of 3D polygons
  • Chi-values now calculated automatically following input of U-values & Psi-values of flanking elements by user
  • New input tool for automatic calculation of areas of flanking elements, as well as input of U-values and description for automatic calculation of Chi-values and visualisation of flanking elements affecting the calculation
  • New rod-shaped component options allow precise input of circular/oval pipe, rectangular sections as well as I-beams to suit user specifications
  • Precise dimensioning tool now included
  • Roof construction tool allows fast and easy modelling of hips, valleys, eaves, verges etc.

CALCULATION METHODS

The finite element mesh calculation is performed in accordance with EN ISO 10211.  Boundary conditions according to BR497 and Passive House are available in the boundary condition tables.

INPUT OPTIONS

Our 3D Psi-Therm program uses a 3D CAD platform, making the creation of 3D thermal bridge construction models quick and easy.

  • 3D-auxiliary lines/offset lines
  • 3D components (bar & plate)
  • 3D-openings (window or break)

COMPONENT EDITING OPTIONS

  • Trim to 1 or 2 levels
  • Cut into 1 or 2 levels
  • Cut out part
  • Move
  • Rotate / Copy

PRESENTATION AIDS

PRINT

The report can be output to many formats including PDF, JPEG, direct to printer and many more. The comprehensive report satisfies all the requirements of ISO 10211 & BR497. Alternatively, the printed content can be limited to the input data, materials listings or the mathematical calculation depending on the user requirements. The print layout can be edited by the user to display only selected images of the model, as well as integrating your own corporate logo into the printed report.

Software

Psi Therm 2D & 3D provides the user with an accessible and easy-to-use interface to construct detailed building sections to determine heat flows & surface temperatures. The software automatically calculates psi-values & fRsi values, and generates comprehensive reports in accordance with the relevant standards & conventions for building regulations compliance. With Psi Therm, the user can improve on standard construction details, providing a significantly improved Y-factor and superior building energy rating, while eliminating mould-growth risk.

Training

London training course taking place 14th - 16th March 2016! Don't miss out on this opportunity to learn how to carry out thermal bridge assessment in 2D & 3D, with our hands-on course. The course is aimed at professionals working in the Passive House area, however is of interest to anyone who wants to understand how to calculate thermal bridges. The course will present all the methods required by the Passive House Institute for ambient junctions as well as the ground floor connections, never before presented in English until now!
