Nearly 10 years in the making, the new permanent exhibition in Los Angeles allows visitors to experience a blend of live animals and hands-on science experiments in 11 distinct ecosystems - each illustrating an ecological principle. The wing nearly doubles the exhibition space at the California Science Centre and is expected to raise visits above the average annual attendance of 1.4m that the facility had previously welcomed.
ETC's Unison Paradigm control system, Sensor+ dimming, SmartSwitch relays and Source Four luminaires were all part of the lighting and control package for Ecosystems. The Paradigm system provides simultaneous control of all the architectural lighting in the public areas, including the central atrium and the 5,600sq.m of new administrative offices, in addition to dry and wet exhibits and special event elements such as a simulated flash flood experience in the 230sq.m desert ecosystem.
As part of its green energy management functionality, Paradigm performs building sweeps, making certain that lights have not been inadvertently left on during unoccupied times. The intuitive colour coded LED button displays allow multiple areas to be controlled via just a few strategically placed stations. And Paradigm can also function as centralised control, accessing the lighting in any specific area of the centre with equal ease.
Every controllable circuit in the expansion wing is operated by the Paradigm system, including ETC's Source Four luminaires, which provide patterned effects and adjustable focus for the changing events in the three storey central atrium.
The ETC system was specified by Gallegos Lighting (now a studio of Thorburn Associates Inc) working in close collaboration with the Science Centre; joint project architects EHDD and ZGF; biome consultant CLR Design; and designers of the Science Museum of Minnesota. Karl Haas, ETC's Architectural Western Regional Manager, was lead project designer on the installation while previously working for Gallegos Lighting Design. ETC's Los Angeles office is providing ongoing support and coordination of continued work with the Science Centre.
