Develop systems to improve energy savings

               •      Most of external light as needed
               •      Most of heat during winter
               •      Blocking excessive radiation during
                      summer

     Light barrier
     Radiation barrier
     Wind barrier
     Heat isolation

  But it is monotonous and has constant cavity.

     The glass façade cladding is static
     The textile façade cladding is also static

  However,
  Conditions around the building are not static.

                                     » Problems in Ventilation



     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.

                                     » Problems in Light and Views



     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

 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

    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.

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
