Spire’s headquarters at 700 Market Street won the Guth Lighting Award.
The award recognizes exceptional interior lighting projects that balance the functional illumination of space with the artistic application of light to enhance the occupant’s experience. The approach to designing the lighting at the iconic building in downtown St. Louis followed architect Philip Johnson’s minimalist, modern style.
The building is listed on the National Register of Historic Places. Its square shape is bisected into two three-story triangles, which center on a circular rotunda. Following Johnson’s original approach, flat lensed 2x2 LED fixtures were selected for the split square volume with round fixtures placed throughout the circular volume. Because the client is a utility company, energy reduction was a major project goal. Strategies to conserve energy include efficient fixtures that reduce power use by 42%, occupancy-sensing fixtures in lower-traffic spaces, and extensive use of natural daylight.
