Liberty’s representatives accompany prospectivetenants through an impressive suite of rooms fitted withsophisticated integrated video imaging and lighting systems.The Lighting Practice designed the architectural lightingelectronic control system and the interface with the a/v presentations,including cueing and dimming.“The lighting acts in support of the simulated tour,”Borden says. “Three-dimensional models and video introduceprospects to the future environment of OnePennsylvania Plaza. Our lighting program uses 48 dimmablecircuits in 32 preset scenes cued to video tracks. The lightlevel establishes mood, creates pathways, focuses attentionand helps to tell the story without diminishing the videoimages.”An audio/visual specialist and a technician from controlsmanufacturer Lutron Electronics Co., Inc. worked withBorden to establish the cues. An RS 232 interface codes andtransmits the signals initiated by the lighting system.According to Borden, the effect achieves “a sense of a smoothjourney.” Employing light and shadow and high contrastwith low-voltage lighting, the system establishes a mood ofexcitement and anticipation.
