An answer to fluttering roofs everywhere, Rhinobond is a mechanical attachment system for thermoplastic roof membranes that allows the roofing material to be spot-welded without penetrating the membrane. At the center of the system is an induction welding technology called Sinch that heats a PVC-coated plate through the membrane. The Sinch process generates enough heat to seal between the plate and the underside of the thermoplastic roof without using direct heat, which would create a hole. (Magnetic cooling weights are placed on the site of the weld until the material has bonded.) The plates are laid out in a grid and fastened to the roof surface using the same clamps that hold the insulation in place. Remembering horror stories from their own projects, the jury was immediately on board with the concept. “This is just an idea whose time has come,” juror John Ronan said. “We have this problem when we use thermoplastic roofs. They start bubbling up and it is always a fight.” Factory test results for standard applications show that a 1-120 uplift rating can be achieved with welds laid out in a 2-foot-by-2-foot grid.

  • Light is also directed by the curved shape of the fixture's housing, one of the object's distinctive aesthetic features.

    LED Streetlight

    The Office for Visual Interaction designed a prototype LED streetlight for New York to cut down on energy use.

     
  • The design for the staircase is centered on folded stainless steel. Hung from a structural steel support on the top level of the townhouse, vertical folded pieces create a continuous screen that encloses the two above-grade flights of stairs. Tabs on the bent risers are fitted into slots on the vertical pieces, which created an easy setup for on-site construction and spot-welding.

    Dynamic Descent

    Dean/Wolf Architects designs a folded stainless steel staircase for a Manhattan townhouse.

     
  • A mock-up of the SFIS with bundled plastic bottles. Most plastic water bottles are discarded with the caps on; capped, empty bottles are airtight and can be placed within a concrete structure to create a void. Hydrostatic pressure from wet concrete will only nominally reduce the air volume inside the bottles.

    Sustainable Form-Inclusion System

    Skidmore, Owings & Merrill design a prototype system that uses plastic bottles, bags, and other compressed waste to lighten and fill spaces in concrete slabs.
