The entire workspace was organized into 4 discrete zones, each comprising multiple groups of retrofit fixtures and downlights. Individual offices and smaller common areas utilized wireless sensors featuring occupancy sensing and daylight harvesting capabilities. As a result, office lights automatically turn on when an employee enters and dynamically dim or brighten based on ambient natural light entering the room. Personalized wall switches allow occupants to easily override programmed dimming levels. Notably, an employee who previously suffered from light sensitivity and relied on a desktop lamp is now able to comfortably dim the overhead fixtures directly in his office.
For larger common areas, NES deployed wireless nodes that enabled fast, wireless grouping of multiple fixtures, supporting scheduling, high-trim adjustments, and customized scenes entirely without the need for traditional 0-10V low-voltage wiring. The color-selectable downlights also provided the flexibility to tailor color temperatures across different working zones.
Beyond the baseline LED conversion—which is estimated to save approximately 250,000 kWh (saving ~$25K in annual electrical costs)—the effective integration of high trim, occupancy detection, and daylight harvesting yields an additional 30–35% in energy savings.
