In 2017 startten de Hogescholen Saxion Enschede en Hanze Groningen Bouwtex, het onderzoek naar de mogelijkheden van textiel voor de bouw in het kader van renovatie en herbestemming van gebouwen.

Op 15 januari is het onderzoek afgerond met een eindevent. Hier de presentatie Textilebased façadepanel for adaptive insulation van studententeam 1.

  1. 1. Smart Solutions Semester ‘ TEXTILE BASED FAÇADE PANEL FOR ADAPTIVE INSULATION’
  2. 2. Group Thijs van Ekelenburg Construction and structural engineering Marijn Vreriks Construction and structural engineering Luc Horstman Construction management Joeri Hoogenkamp Construction management Yi Wei Fashion & Textile Technology
  3. 3. Agenda The Project Research question Research method Starting out Process Final concept Test equipment Regular testing conditions Results Introduction Developping the panel The data
  4. 4. Agenda The Project Research question Research method Introduction
  5. 5. The project • Textile based façade panel for adaptive insulation • Lectorate Sustainable Building Technology & Material • BouwTex • Client C. Struck and B. Bruins • Develop concept model
  6. 6. Research question Main question: “What is the quantitative effect in a traditional cavity wall with a mounted adaptive textile façade panel under varying circumstances and how can the current concept be improved to minimize the heat flux to reduce the energy consumption?”
  7. 7. Research method
  8. 8. Research method
  9. 9. Starting out Process Final concept Developping the panel
  10. 10. Process
  11. 11. Begin situation The panel is not completly filled with water and it became a bag Textile panel with 3D texture inside for a better stability
  12. 12. Begin situation The panel is not completly filled with water and it became a bag Textile panel with 3D texture inside for a better stability
  13. 13. Begin situation The panel is not completly filled with water and it became a bag Textile panel with 3D texture inside for a better stability
  14. 14. Concept 1 First experiment to create seams in the textile to get a beter water flow in the panel
  15. 15. Concept 2 To get a good water flow we’ve create seams with glue in the 3D texture The glue was not strong enough
  16. 16. Concept 2 To get a good water flow we’ve create seams with glue in the 3D texture The glue was not strong enough
  17. 17. Concept 3 Textile panel with 3D texture inside and cut out seams in the 3D texture and sewed it with an ultrasonic sewing machine The seams are too insufficient
  18. 18. Concept 4 Panel with 3D structure and a drainage pipe at the top like a shower The water did not spread well and it became a bag
  19. 19. Concept 4 Panel with 3D structure and a drainage pipe at the top like a shower The water did not spread well and it became a bag
  20. 20. Concept 5 The settings of the ultra sonic sewing machine didn’t worked out so the panel was leaking on different places. Connections for in and output were not possible. Panel with a new flow design by using sewing seams
  21. 21. Concept 6 The settings of the ultra sonic sewing machine were good. Connections for in and output were glued but didn’t worked out. Panel with same flow design by using sewing seams
  22. 22. Concept 6 The settings of the ultra sonic sewing machine were good. Connections for in and output were glued but didn’t worked out. Panel with same flow design by using sewing seams
  23. 23. Concept 7 The settings of the ultra sonic sewing machine were good. Connections for in and output by using textile in combination with clamps Panel with same flow design by using sewing seams. Only problem was that the panel pulled together.
  24. 24. Final concept The settings of the ultra sonic sewing machine were good. Connections for in and output by using textile in combination with clamps. By using a new frame the panel stayed in original form Panel with same flow design by using bigger sewing seams
  25. 25. Final concept The settings of the ultra sonic sewing machine were good. Connections for in and output by using textile in combination with clamps. By using a new frame the panel stayed in original form Panel with same flow design by using bigger sewing seams
  26. 26. Test equipment Regular testing conditions Results The data
  27. 27. Test equipment • IsoTemp recirculation pump • Cavity wall, with cut-out insulation • Heatflux measuring tool, mounted on the inside wall • Two thermometers, mounted on the inside and outside of the wall • IR-camera • Industrial heater
  28. 28. Regular testing conditions • Room temperature 19 degrees • Water temperature 17-17,5 degrees • Water pressure 96 ml/s
  29. 29. Results • Testing without heating • Testing with a warm wall • Testing with heater and panel • Testing with heating from the inside
  30. 30. When the water is running through the textile panel we can actively control the Heatflux 0 0,2 0,4 0,6 0,8 1 1,2 1,4 0 10 20 30 40 50 60 70 80 90 100 DegreesCelsuis Time (Measurement point every 20 sec) Testing without heating Delta T (TC1 - TC2) Poly. (Delta T (TC1 - TC2)) Test conditions • Start temp. wall 21,3 degrees Celsius • End temp. wall 21,6 degrees Celsius • Water temp. 17-17,5 degrees Celsius
  31. 31. This is a surprising result. We expected that the temperature of the outside wall would be lower than it is now. Clarification could be that the panel causes a space of still air, which is a good insulation. 0 0,2 0,4 0,6 0,8 1 1,2 1,4 1,6 1,8 1 11 21 31 41 51 61 71 81 Degreescelsius Time (Measurement point every 20 sec) TESTING WITH A WARM WALL Delta T (TC1 - TC2) Poly. (Delta T (TC1 - TC2)) Test conditions • Begin temp. wall 21 degrees Celsius • 1 hour heated by 70 degrees Celsius • Wall temp. start testing 24,5 degrees Celsius • End temp. wall 23 degrees Celsius
  32. 32. The begin water temperature of the panel was 17,5 degrees Celsius. After the test the water temperature increased to 32 degrees. This shows that the panel could be used as a heat collector. 0 0,2 0,4 0,6 0,8 1 1,2 1,4 1 101 201 301 401 501 601 701 DegreesCelsius Time (Measurment point every 10 sec) TESTING WITH HEATER AND PANELTest conditions • Start temp. wall 21,5 degrees Celsius • End temp. wall 23,3 degrees Celsius • Begin temp. water 17,5 degrees Celsius • End temp. water 32 degrees Celsius
  33. 33. The temperature of the inside and the outside of the wall rises at the same time, although the heater was pointed towards the inside thermometer. -1 -0,8 -0,6 -0,4 -0,2 0 0,2 0,4 0,6 0,8 1 1 101 201 301 401 501 601 701 801 901 1001 DEGREESCELSUIS Time (Measurement point every 20 sec) TESTING WITH HEATING FROM THE INSIDE Delta T (TC1 - TC2) Poly. (Delta T (TC1 - TC2)) Test conditions • Start temp. inside wall 17,3 degrees Celsius • Start temp. outside wall 17,8 degrees Celsius • End temp. inside wall 23,6 degrees Celsius • End temp. outside wall 23,1 degrees Celsius • Panel filled with air
  34. 34. Conclusion and recommendation • When the water is running through the textile panel we can actively control the Heatflux • Seeing how the water in the panel also collects heat, it is possible to use the panel as an alternative to the industrialised sillicium solar collectors. • This in combination with heating up the water instead of the wall it can function as an insulator as well. However this needs to be verified through follow up research using an actual cavity wall.
