Philadelphia, PA

The lighting designers’ challenge for Cira Centre, a 29-story office high-rise in Philadelphia’s CBD, was to light a glass tower with no projections, setbacks or crown to capture the lighting. The solution was to create a “wallpaper of light.” Color changing LED fixtures are concealed in shadow boxes behind the glass curtain wall, to create infinite compositions of color and movement.

This thematic element is brought inside to the main lobby, where its reinterpretation in white is detailed into a 50-foot high wall that is only four inches in depth.

The tower can be transformed for special events; changing from a pure glass sculptural form by day to a celebration of light at night.
