Software for calculating heat flows, thermal bridges, isotherms and Uf-values
Demo version

Software for calculation of heat flows, thermal bridges, isotherms and Uf-values according to EN ISO 10077-2:2018

With the help of WINISO software, you can calculate heat flows, thermal bridges, isotherms and Uf values according to EN ISO 10077-2:2018 as well as Ufr, Ueg and Ucg values according to ISO 15099/ NFRC.

The software includes automated CAD file preparation. It allows you to have imported files automatically corrected of CAD errors. Even complex components can be analyzed and calculated in a short time. The integrated FEM calculation kernel enables the most accurate results. The meshing of the finite elements is done fully automatically and with manually adjustable accuracy. Radii and slopes are represented in detail by an FEM mesh.

A special advantage of the software is the automatic material recognition. If the designation of the individual layers of the CAD file corresponds to the extensive WINISO® database, the surfaces are automatically filled with the corresponding material. If special materials are required for the calculation, you have the possibility to add them to the database by entering a few parameters.

Features of WINISO

  • Highly automated geometry preparation of CAD data (.dxf and .dwg)
  • Detailed import of CAD data incl. radii and bevels
  • Automatic material allocation based on CAD layers
  • Gas filling for inter-pane spaces according to DIN EN 673 freely mixable
  • New solver and new calculation core with automatic FEM meshing
  • Calculation according to the "radiosity model" (new cavity model according to EN ISO 10077-2:2018) and with equivalent conductivity (EN ISO 10077-2:2012/2018)
  • Automated Uf calculation of window and facade profiles
  • Calculation of isotherms, surface temperatures and temperature factor according to DIN 4108-2/-3
  • Easy definition of foils, coatings and surface properties by line drawings
  • Psi-values of thermal bridges and insulating glass spacers according to EN ISO 10211 and EN ISO 10077-2
  • Ug-values of multi-pane insulating glass according to EN 673
  • U-values of any construction according to EN ISO 6946

WINSIO® modules and add-ons:

  • WINISO® basic module: Calculation of heat flows, thermal bridges, isotherms and Uf-values according to EN ISO 10077-2:2018
  • WINISO® Humidity: Calculation of relative humidity, vapor diffusion and condensation failure
  • WINISO® batch processing: automatic calculation of multiple WINISO® files
  • ISO 15099
  • Uw-value

WINISO® has been extended by the calculation according to the American standard ISO 15099. The add-on "ISO 15099" supports the relevant calculations of Ufr, Ueg and Ucg calculation according to ISO 15099 and NFRC. After the calculation is completed, you can generate the printout specifically for ISO 15099 and get a list of the materials used. The calculation results with associated imperial units are also given
