PARAMETRIC SURFACE APPROACH TO TEXTILE FAÇADES
» Problems with Glass Façades
• Locality ignored
• Changing climatic conditions in proximity of
building ignored
• Glare due to extreme light levels
• Unpleasant feeling due to radiation

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

Aesthetical freedom
The cavity between the façade and the screen can
be changed for different forms of ventilation

•
Use the position of the Sun wisely
Use the wind efficiently
Use scene of the surrounding as wish
Change the outlook of the building

» Benefits in Ventilation



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.

» Benefits in Light and Views



Based on the orientation of the building, level of
light entrance can be controlled.
External views are also controllable.
Impact on the architectural aspect.

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
