INSTALLATION AND CONTROL
Danny and the architect met on-site to discuss possible concepts. They agreed that accenting the pilasters using ground-mounted controlled beam projectors was the best approach. Fixture locations were determined through computer mockups to create the optimal contrast of light and shadow. They utilized a 3D export from the client's Revit model to create a SketchUp replica of the building, allowing the use of lighting software to create visual concepts.
The luminaires were installed on concrete pads, providing a stable base for the fixtures. Each fixture featured a yoke for adjustability, allowing for precise aiming during installation. The fixtures at the top of the building were powered by remote drivers, making them almost invisible against the building’s facade. And the 0-10V dimming control system allows the owner to adjust the lighting levels as needed, adding to the overall functionality of the design.
CONCEPT DEVELOPMENT The first concept (previous page) used ground-mounted 3,600-lumen projector spots with a 7-degree beam positioned to illuminate only the sides of the pilasters, providing a nice light/shadow contrast on the pilasters and in between.
Despite the complexities of the project, the team did not encounter significant supply chain issues. GVA Lighting’s reliable supply and the support from Southern Lighting Source, the local representative, ensured a smooth process. The primary challenge was achieving the correct lighting angles and integration with the building’s architecture, which was successfully addressed through mockups and commissioning.
For the second concept (above), the projector spots were relocated to the front of the pilasters. Although this illuminated less of the overall vertical surface, it provided a better contrast of light and shadow, adding a nice accent to the top of the building.
The project’s success was evident in the owner’s satisfaction. The lighting design matched the initial renderings closely, and the final result impressed the stakeholders, whose building now beautifully adorns one of Nashville’s busiest streets. ■
IMPLEMENTATION AND DETAILED EXECUTION
GVA Lighting was chosen as the fixture provider due to their precision and quality. The ground-mounted fixtures were 50-watt luminaires with a color temperature of 4,000K, consistent throughout the project. The topmounted fixtures were 10-watt luminaries, also 4,000K. The seven-degree pencil beam added precision for the building's architectural features. Mockups played a crucial role in the success of this project. The slight inward tilt of the pilasters required meticulous planning to achieve the desired lighting effect. By conducting mockups, the team could test different settings and make necessary adjustments before finalizing the installation. This process ensured that the final lighting design met both aesthetic and functional goals.

The consensus was for option two. However, the design was updated by adding small seven-degree spots just below the highlighted roofline to illuminate the tops of the pilasters.
