Together, they'll give the pavilion its shape, strength and transparency. Components for the A-frames were cut out of big sheets of steel plate, welded together, ground and finished. Shapes were determined digitally, from a computerized model of the pavilion and its underlying structure. The fixed 'building spine' will top off the A-frames. Above it, two rotating spines will support the movable wings of the brise-soleil, an enormous sunscreen that can be positioned to admit or keep out sunlight.
Light is crucial in the concept and operation of the pavilion.
By day, it will have natural light. At night, artificial illumination will be provided by powerful lights set low around the concrete ring beam. Appeared in the Milwaukee Journal Sentinel on March 5, 2000.
