  1. PARAMETRIC SURFACE APPROACH TO TEXTILE FAÇADES Parametric Surface Approach to Textile Façade Cladding Prof.Ramon Sastre Eng. Müfit Eribol, MSc, MBA, Archineer h.c. Arch. Rana Dirin, Archineer h.c. ETS Arquitectura del Vallès, Universitat Politèchnica Catalunya, Spain ONART Membrane Structures, Turkey

  2. »The Goal PARAMETRIC SURFACE APPROACH TO TEXTILE FAÇADES • Develop systems to improve energy savings • Most of external light as needed • Most of heat during winter • Blocking excessive radiation during summer ETS Arquitectura del Vallès, Universitat Politèchnica Catalunya, Spain ONART Membrane Structures, Turkey

  3. »Current Approach PARAMETRIC SURFACE APPROACH TO TEXTILE FAÇADES • Glass façade cladding • Textile façade cladding • Canopies • Shutters, eaves • Roller blind • Sun breakers • Reflective coatings • Heat isolation systems ETS Arquitectura del Vallès, Universitat Politèchnica Catalunya, Spain ONART Membrane Structures, Turkey

  4. »Problems with Glass Façades PARAMETRIC SURFACE APPROACH TO TEXTILE FAÇADES • Locality ignored • Changing climatic conditions in proximity of building ignored • Glare due to extreme light levels • Unpleasant feeling due to radiation ETS Arquitectura del Vallès, Universitat Politèchnica Catalunya, Spain ONART Membrane Structures, Turkey

  5. » Textile Façade Cladding as theMost Popular Solution PARAMETRIC SURFACE APPROACH TO TEXTILE FAÇADES • Light barrier • Radiation barrier • Wind barrier • Heat isolation • But it is monotonous and has constant cavity. ETS Arquitectura del Vallès, Universitat Politèchnica Catalunya, Spain ONART Membrane Structures, Turkey

  6. »Problem with Existing Façades PARAMETRIC SURFACE APPROACH TO TEXTILE FAÇADES • The glass façade cladding is static • The textile façade cladding is also static • However, • Conditions around the building are not static. • Sun light • Wind • View preferences ETS Arquitectura del Vallès, Universitat Politèchnica Catalunya, Spain ONART Membrane Structures, Turkey

  7. » Problems in Ventilation PARAMETRIC SURFACE APPROACH TO TEXTILE FAÇADES • The cavity is thought to provide better thermal behaviour. This holds true if cavity dimensions are sufficient. • Often, it is not enough. Rain protections at top make it worse. • Side openings are only useful for tangential winds. ETS Arquitectura del Vallès, Universitat Politèchnica Catalunya, Spain ONART Membrane Structures, Turkey

  8. » Problems in Light and Views PARAMETRIC SURFACE APPROACH TO TEXTILE FAÇADES • In many countries west façades receive the sun radiation perpendicularly. Eaves and brise-soleils are not effective. • Continuous solar screens prevents clear view. • Poor natural light level ETS Arquitectura del Vallès, Universitat Politèchnica Catalunya, Spain ONART Membrane Structures, Turkey

  9. What can be the solution? PARAMETRIC SURFACE APPROACH TO TEXTILE FAÇADES ETS Arquitectura del Vallès, Universitat Politèchnica Catalunya, Spain ONART Membrane Structures, Turkey

  10. »Proposed Approach PARAMETRIC SURFACE APPROACH TO TEXTILE FAÇADES • Parametric Surfaces • Aesthetical freedom • The cavity between the façade and the screen can be changed for different forms of ventilation ETS Arquitectura del Vallès, Universitat Politèchnica Catalunya, Spain ONART Membrane Structures, Turkey

  11. »Strengths and Advantages PARAMETRIC SURFACE APPROACH TO TEXTILE FAÇADES • By changing the surface, • Use the position of the Sun wisely • Use the wind efficiently • Use scene of the surrounding as wish • Change the outlook of the building ETS Arquitectura del Vallès, Universitat Politèchnica Catalunya, Spain ONART Membrane Structures, Turkey

  12. »Continuum PARAMETRIC SURFACE APPROACH TO TEXTILE FAÇADES • E.T.S. Architectura del Vallès participatedin European Lifelong Learning Program • First workshop in September 2008 in Lyon. Focus: Changing the façade geometry • Second workshop May 2009 in Barcelona: Focus: Parametric geometry ETS Arquitectura del Vallès, Universitat Politèchnica Catalunya, Spain ONART Membrane Structures, Turkey

  13. »Steps taken PARAMETRIC SURFACE APPROACH TO TEXTILE FAÇADES • Developed a new software to give volume • Different surfaces through parameters • Regular rectangular patterns on the façades • Floors delimit the vertical space • Vertical struts delimit horizontal space ETS Arquitectura del Vallès, Universitat Politèchnica Catalunya, Spain ONART Membrane Structures, Turkey

  14. »Software at First Workshop PARAMETRIC SURFACE APPROACH TO TEXTILE FAÇADES ETS Arquitectura del Vallès, Universitat Politèchnica Catalunya, Spain ONART Membrane Structures, Turkey

  15. » The Model PARAMETRIC SURFACE APPROACH TO TEXTILE FAÇADES ETS Arquitectura del Vallès, Universitat Politèchnica Catalunya, Spain ONART Membrane Structures, Turkey

  16. » Second Workshop PARAMETRIC SURFACE APPROACH TO TEXTILE FAÇADES • Focus was on parametric geometry for façades • Rhinoceros & Grasshopper software • Grid of rectangles called quads • Created a complex surface ETS Arquitectura del Vallès, Universitat Politèchnica Catalunya, Spain ONART Membrane Structures, Turkey

  19. » Node Disaggregation 1 PARAMETRIC SURFACE APPROACH TO TEXTILE FAÇADES ETS Arquitectura del Vallès, Universitat Politèchnica Catalunya, Spain ONART Membrane Structures, Turkey

  20. » Node Disaggregation 2 PARAMETRIC SURFACE APPROACH TO TEXTILE FAÇADES ETS Arquitectura del Vallès, Universitat Politèchnica Catalunya, Spain ONART Membrane Structures, Turkey

  21. » Node Disaggregation 3 PARAMETRIC SURFACE APPROACH TO TEXTILE FAÇADES ETS Arquitectura del Vallès, Universitat Politèchnica Catalunya, Spain ONART Membrane Structures, Turkey

  22. » Benefits in Ventilation PARAMETRIC SURFACE APPROACH TO TEXTILE FAÇADES • Triangle openings improve ventilation in a significant way. • It is easy to find opening area for in and out air movements • Not for just convection air movements but also for perpendicular or tangential winds. ETS Arquitectura del Vallès, Universitat Politèchnica Catalunya, Spain ONART Membrane Structures, Turkey

  23. » Benefits in Light and Views PARAMETRIC SURFACE APPROACH TO TEXTILE FAÇADES • Based on the orientation of the building, level of light entrance can be controlled. • External views are also controllable. • Impact on the architectural aspect. ETS Arquitectura del Vallès, Universitat Politèchnica Catalunya, Spain ONART Membrane Structures, Turkey

  24. » Construction PARAMETRIC SURFACE APPROACH TO TEXTILE FAÇADES • Parametric surface goes well with CNC production. • Nodes of the grid are connected to façade • Pegs are perpendicular to façade • Pegs provide anchorages • Patterning like hypars • Borders can be bolt ropes or tubes ETS Arquitectura del Vallès, Universitat Politèchnica Catalunya, Spain ONART Membrane Structures, Turkey
