Sommer Informatik GmbH 1
The company Sommer Informatik GmbH domicile at Rosenheim foundation 20 years ago by the director Robert Sommer market leader at the isotherm- and frame-uvalue calculation section close collaboration with research, lore and industry business area: property management building physics statics 2
WinIso2D The software solution to calculate two-dimensional heat flow and steam diffusion flow, isotherms, U f -Values and Psi-Values with a DXF-port 3
CAD-Conversion a highlight of the software is the fast import of CADdrawings all mistakes and for the calculation unnecessary details, like open lines, hatchings and letterings get purged at the converter 4
CAD-Conversion The purged drawing can get exported to WinIso and get edited further or evaluated at once 5
Material database The Software offers a widespread material database, based on valid European norms 6
Material database detailed information are deposited and can get reviewed for each material furthermore it is possible to add some proper material to the database 7
Isotherms Isotherms are curves with the same temperature a good isotherm profile is a quality feature for a good building element the most valuable isotherms, like the 13 C isotherm, get distinguished in terms of color 8
Temperature fields In addition to that, the display of the temperature fields provide for a graphical representation 9
Heat flow fields Heat flow fields show, where the potential for improvement of the building element concerning the heat transfer is 10
U-value the U-value is an amount, how much heat per unit of area get lost through a building element the extensive calculation by hand get omitted by using WinIso 2D 11
f Rsi -value the f Rsi -value delivers the requirement to the avoidance of the growth of moulds according to the DIN 4108-2 it is a ration between the lowest temperature of the surface inside and the outside temperature 12
U f -value the U f -value is the U-value of the frame and get calculated according to EN ISO 10077-2 without a software, the U f - value only could be determined with extensive measurements 13
Psi-value the psi-value is the length-related heat transfer coefficient and gets calculated according to EN ISO 10211 and EN ISO 10077-2 all calculations for the working group Warm Edge got calculated with WinIso 2D 14
Psi-value the psi-value couldn t get calculated without a software, by reason that the thermal conductance L 2D is also needed out of a heat flow software all valuable measures get determined automatically by the program so that the psivalue can get calculated quickly 15
Printout The printout delivers a pleasant presentation of the result 16

Characteristics U f -values of window-and facade profiles according to EN ISO 10077-2 Psi-values of thermal bridges and insulating glass spacers according to EN ISO 10211 and EN ISO 10077-2 U g -values of multiple-glazing insulating glass according to EN 673 U-values of arbitrary constructions according to EN ISO 6946 Calculations of isotherms, surface temperatures and temperature factors according to DIN 4108-2 Temperatures retrievable at any point of the construction Simple assumption and conversion of CAD-data by using the DXF-Converter Widespread Material database based on European norms Mold- and condensate free detailed planning Calculation of complex profiles with free definable materials and climate 18
