About us

Founded in 1996, Sommer Informatik GmbH from Rosenheim stands for highly qualified software solutions in the fields of building physics and structural analysis of windows, façades and glass.

The software portfolio includes calculations for the structural analysis of horizontal and vertical glazing for Germany, Europe, Switzerland, Austria and the USA, as well as calculations of light, solar and thermal characteristics of glazing in combination with solar shading.

In addition, calculations of thermal stresses occurring in glass surfaces can be carried out. The range is rounded off by software for calculating heat flows, isotherms, Uf and Ψ values in accordance with EN ISO 10077-2 as well as Ufr, Ueg and Ucg values in accordance with ISO 15099 / NFRC 100 with 2D and 3D thermal bridge calculation.

Continuous collaboration with research and industry enables the high quality standard of the software solutions.

WINISO® Software

WINISO® 3D

Calculation of heat flows, 2D and 3D thermal bridges, isothermal surfaces and U-values according to EN ISO 10211

Imported 3D CAD data can be intuitively and efficiently cleaned of errors and prepared. The essential details can be worked out specifically and true to the original from extensive and complex source data. After simple processing and a short calculation time, the FEM calculation kernel delivers the thermal properties of the detail with maximum accuracy.

Performance features

  • Highly automated geometry preparation of CAD data (DXF, DWG, STEP)

  • Detailed transfer of CAD data. Recognition of curved surfaces (radii, freeform) Automatic and manual preparation

  • FEM calculation with flexible automatic tetrahedron meshing. Automatic mesh refinement on small-scale geometry details

Furthermore, the structure can consist of any number of glass panes and a lamella module is available as an add-on. After your calculation, the determined performance data for the respective product variants can simply be transferred to the declaration of performance and printed out.

Features

  • Extensive database with various products from international glass and sun shading manufacturers

  • Import of own spectral data

  • Boundary conditions according to EN 52022-3 or freely definable

  • Calculations in accordance with US standard ISO 15099/ASHRAE

  • Calculation of any pane structure

  • Display of the temperature curve across the cross-section

  • Calculation of reflection, transmission and absorption

  • Calculation of the Ug-value according to EN ISO 673

  • Calculation of the Ug-value and the SHGC-value according to ISO 15099 / ASHRAE

  • Calculation of the g-value according to EN 410

  • Calculation of the gtot value according to EN ISO 52022-3

  • Creation of a declaration of performance and CE marking for any glass structures in many language versions

WINSLT® Software

WINTHS®

WINTHS® is the software solution for simple and user-friendly calculation of the climatic conditions acting on glass panes, taking into account geographical location and historical weather data in accordance with NF DTU 39 P3.
WINTHS® makes it possible to determine the occurring thermal stresses on glass surfaces in advance with regard to extreme weather data, thus drastically minimizing the risk of glass breakage.

In the calculation, WINTHS® takes into account a wide range of factors that influence the thermal loads on glass surfaces. The pane structure is fundamental: glass quality, edge quality, gaps, gas fillings, type and thickness of the frame and its thermal inertia.
These values are set in relation to the prevailing climatic conditions at the installation site. The basis for this can be existing climate data (average and extreme values) for this region, as well as freely selectable values.

The results are displayed in the form of graphs. In addition, all relevant calculation results are displayed to the user in a detailed report, including a summary of whether the respective glass structure satisfies the locally prevailing temperature fluctuations.

Features

  • Calculation according to NF DTU 39 P3

  • Extensive database with products from international glass and sun protection manufacturers

  • Calculation of any pane structures and shading arrangements

  • Detailed thermal modeling of the frame for low, medium or high thermal inertia

  • Over 3600 international climate data sets available. Display of outdoor temperatures, solar radiation, cloud cover, air quality and ambient albedo

  • Comprehensive mapping of properties and installation conditions of the glazing: orientation, partial shading, coatings, printing, storage, processing of the glass edg

  • All special cases in accordance with NF DTU 39 P3: external solar shading, internal opaque elements, sliding elements, projecting glazing, wall insertion, heat sources

  • Graphical evaluation in diagram form, with false colors and as time-resolved animation

  • PDF reports for documentation and communication of proofs

  • Structured saving of projects in the SommerGlobal® database and intuitive data exchange with the SommerGlobal® applications WINSLT®, GLASGLOBAL® and WINISO®
