  1. PHYSIBEL Using BISCO for the thermal simulation of window framesaccording to EN ISO 10077-2

  2. Example 1 1. frame drawing in CAD format

  3. 2.a. save drawing as bitmap2.b. keep material border lines only

  4. 3. colour filling using bitmap editor

  5. 4. use BISCO EN ISO 10077-2 template colours

  6. 4. use BISCO EN ISO 10077-2 template colours

  7. 5. start BISCO and load template data now the colours are defined according to EN ISO 10077-2

  8. 6. load the window frame bitmap now material thermal conductivities and indoor and outdoor conditions are defined according to EN ISO 10077-2

  9. 7. define the frame width it is sufficient to define 1 measure !

  10. 8.a define the white colour as a cavity property 8.b. split the white zones into separate zones

  11. 8.b. split the white zones into separate zones now each cavity gets the correct equivalent thermal conductivity !

  12. 9. enlarge the bitmap to the right

  13. 9. enlarge the bitmap to the right

  14. 10. add the zones with reduced heat transfer

  15. 11.a. define distances both the window frame width and the insulation panel width need to be defined for the U-value calculation

  16. 11.b. define parameters for U-value calculation

  17. 12. define the triangulation measure

  18. 13. calculation after the automatic triangulation, a system of 5223 equations is built up and solved14. graphic output

  19. 14. graphic output isotherms and heat flow lines15. text output temperature, heat flows frame thermal transmittance

  20. Example 2 1. frame drawing in CAD format2. save drawing as bitmap

  21. 3. start BISCO and load frame bitmap

  22. 3. fill line drawing requires black lines on a white background

  23. 3. fill line drawing contour fields are filled with separate colours and lines are eliminated

  24. 4. load template data now the colours are defined according to EN ISO 10077-2

  25. 5.a. load window frame bitmap5.b. apply template colours template colours for materials and for boundary conditions white colour for cavities

  26. 6. define the frame width it is sufficient to define 1 measure !

  27. 7.a define the white colour as a cavity property 7.b. split the white zones into separate zones

  28. 7.b. split the white zones into separate zones now each cavity gets the correct equivalent thermal conductivity !

  29. 8. glazing cavity definition option 1. specify gas filling and coating emissivity option 2. specify equivalent thermal conductivity

  30. 9. enlarge the bitmap to the left and to the right

  31. 9. enlarge the bitmap to the left and to the right

  32. 10. add the zones with reduced heat transfer

  33. 11. calculation after the automatic triangulation, a system of 4953 equations is built up and solved12. graphic output isotherms and heat flow lines

  34. 12. graphic output example surface condensation analysis
