Appendix 14. Lighting.  


Latest version.
  • (a)

    Interior lighting seen through pedestrian skywalk and skytram fenestration shall be inconspicuous, non-glare, non-animated and cannot pose a traffic hazard. Interior lighting seen through skybuilding fenestration, in the Downtown Area Overlay District, shall be inconspicuous, non-glare, and may be animated provided it is not deemed to be a traffic hazard. Access corridor lighting, to the skyway, shall be brighter than the skyway lighting to provide better visibility. When lighting is used as a design element, it should be used consistently throughout the project, including the skyway. Lighting of the skyway should be designed in harmony and balance with the entire structure. Lighting which adds importance or prominence to the skyway is not permitted if it could make the skyway become a distraction or cause confusion to pedestrian or vehicular traffic (i.e., flashing, glaring lighting must be avoided).

    (b)

    Exterior lighting and indirect surface lighting on the exterior of the skyway is acceptable and encouraged so that skyway structures will not look like heavy dark shapes in the night sky. The ceiling, beneath the skyway, must be lighted either directly or indirectly. Indirect lighting, through the use of uplighting, is recommended. The exterior lighting should reduce the contrast between the lights installed to illuminate the right-of-way beneath the skyway and the dark ceiling. Lighting of the right-of-way, beneath a skybuilding, is required. This lighting shall maintain a minimum of 30 footcandle of light during daylight hours, and ten foot candle of light during hours of darkness, measured at three feet above grade. Metal halide lights are required.

    (c)

    Where possible, natural lighting should be used in addition to external non-glare and inconspicuous artificial light to mitigate possible "tunnel effects" below the skyways.
