Mercedes-Benz Future Lab 2.1

 

To address design evolutions desired by Mercedes-Benz and to reduce costs, Future Lab 2.1’s ‘squircle’ is simplified to a circle, its Level 1 reshaped, and alternatives to its façade tested.

 

The two non-cantilevered edges of the now-circular Level 1 are lifted,…

…creating an increased slope for the Lecture Hall, the main access from the Campus Plaza to the Sculpture Garden,… 

…and a sloped, arced vehicle display in the Workshop.

Resultant Level 1: Create-the-Future (Workshop, Genius, Lab, Lecture Hall)

Facade Test A: applying Future Lab 2.1’s undulating, double-curved façade to scheme 2.2 (shown here with rotating photovoltaic sunshade/glare control curtain deployed and then lifted)

To analyze façade costs, three options are tested on scheme 2.2’s new geometry: 1) application of version 2.1’s undulating, double-curved façade; 2) application of an undulating, single-curved façade that approximates a double-curved effect; and 3) application of a smooth, double-curved façade akin, although inverted, to scheme 2.0.

Facade Test B: advancing Future Lab 2.1’s undulating, double-curved façade with a more economical, undulating, single-curved facade (shown here with curtain deployed and then lifted)

Study of undulating, single-curved facade

A double-curved effect can be achieved from single-curved, trapezoidal panels of different shapes with uniform cylindrical folds of various angles. The optimized geometry is composed of 160 top panels with a fold angle variance of 67.22 to 68.02 degrees, and 160 bottom panels with a fold angle variance of 66.31 to 68.97 degrees.

All 320 differently-shaped trapezoidal panels can be produced on a single jig with a uniformly cylindrical fold.

When the cylinder radii of the panel folds are larger than R1000 mm, the appearance of smooth, curved, vertical transitions from top panels to bottom panels—resembling double-curved surfaces—can be achieved while maintaining single, uniform curvature for all panels.

Facade Test C: replacing Future Lab 2.1’s facade with smooth, double-curved panels more akin, although inverted, to scheme 2.0 (shown here with curtain deployed and then lifted)

Study of smooth, double-curved facade

The third, selected facade geometry is composed of 144 smooth, double-curved glass panels. The façade is made cost-effective using triaxial symmetry which limits the average meridian radii of the panels to 18, thus requiring only 18 unique jigs for fabrication. 

To generate the efficient shell geometry, meridian arcs are created from the roof line to the lower slab edge, with a constant midspan offset from vertical of 2.5 m (8.2 ft); each panel is a lofted interpolation between circular arcs. The resultant panels have a maximum and minimum average meridian radius of 20.9 m (68.6 ft) and 16.2 m (53.1 ft), with a maximum and minimum differential in average meridian radius between neighboring panels of 374 mm (1.23 ft) and 90 mm (0.30 ft): tolerances which can be easily accommodated.

To further optimize costs, the 18 unique jigs are created through a limited number of reconfigurable arced metal ribs.

The changing nature of the Future Lab’s image (with its rotating photovoltaic sunshade/glare control curtain) and its contents (with its reconfiguring Media Screens) has the power to continually surprise.
