The BJC at the Commons five-story administrative office building pushes the limits of tilt-up design. The innovative design is comprised of tilt-up panels set to the height of the fifth floor window sill. A concrete spandrel panel framed in steel encloses the top of the building above a continuous ribbon of glass. The building BJC Healthcare's first tilt-up project.
Punched window opening were carved from the concrete panels on the north and south elevations, providing a unique rhythm to the facade while controlling daylight to the interior. The building takes full advantage of the large punched windows to minimize the need for interior lighting. A lighting power density of 0.6 watts per square foot was achieved, which is well below the 0.9 watts per square foot required in the energy code.
