A 600-panel tessellation spreads sunlight underground
By now you know about the Lowline, the ambitious project to turn the 1.5 acre abandoned trolley terminal under Delancey Street in New York City into a public park. In just two weeks the project’s founders, Dan Barasch and architect James Ramsey, will unveil a preview of the remote skylight system designed to transmit sunlight into the Delancey Underground in a life-size, fully functional installation currently being built into the Essex Street Market. Ramsey designed the remote skylights with a network of fiber optic cables that channel light gathered by a solar collection dish down below ground where it’s dispersed. To make the most of the available sunlight, Ramsey enlisted the help of industrial designer Edward Jacobs, the former head of design at Confederate Motors, the high-end motorcycle company, who Ramsey describes as “a visionary and pretty much the most talented guy I’ve ever met.”
To disperse the sunlight as far as possible, Jacobs developed a tessellated canopy system made up of 600 ⅛ inch-thick hexagonal and triangular panels laser cut from clear anodized aluminum and bent in a hydraulic press. In an effort to maximize the sunlight’s reach, the tessellated curvature is so specialized that no two panels are exactly alike. To get the shape and size of each panel just right, Jacobs worked with the engineering group Arup on materials testing and light readings, noting that 3D rendering only goes so far because “the ideas of light perception amount and reflectance can be quite counter intuitive.” The panels, which are fabricated by Milgo Bufkin in Brooklyn, are labeled according to their position in the overall structure and screwed together with fold-over tabs on each side. The canopy is then attached to a four-cable truss system Jacobs developed so the entire 1,350-pound unit can be easily raised and lowered for maintenance. A few cables will also be attached to the outer edges of the canopy to eliminate any possibility of sag between the structural rib span, completing a system that Jacobs describes as “a combination of cable slings, clevises, electrical winches and safety hooks.” Read More
Let There Be Light: Low Line Exhibit
Mark Miller Gallery
92 Orchard Street
Through April 29th, 12-6pm
The team of innovators continues to push forward with a proposal for the Delancey Underground, transforming an underground trolley terminal into a public park for Manhattan’s Lower East Side. An exhibit detailing the proposal for the so-called “Low Line” will be running throughout April at the Mark Miller Gallery. The show entitled Let There Be Light was organized by Delancey Underground co-founders James Ramsey and Dan Barasch in an effort to engage the public directly with the ideas and innovations underpinning the project.
