Philips Lighting Distribution Center

Customer Profile:

Philips Lighting Distribution Center, located in Ontario, California, supplies material to a large portion of the west coast.and operates 24-hours a day. Considering the energy crisis in California, reducing energy consumption is of utmost importance.

Customer Issues:

• Increased Energy and Maintenance Cost
• Older Lighting Technologies
• Several Areas with Minimal Occupancy
• Variety of Lighting Technologies
• Low Light Levels on Vertical Surfaces

Project Objective:

The new lighting system was designed to take advantage of new technologies, reduce utility costs, and improve the vertical lighting at the warehouse shelving. Lighting control was added to reduce energy consumption in low occupancy areas. When these areas are unoccupied, the fixtures are off.

Results:

Improved lighting systems and reduced utility cost were achieved by replacing the existing HID lighting system in the warehouse, receiving and shipping areas with new T5HO fluorescent fixtures. As you can see in the pictures to the right, the vertical lighting was increased dramatically. On the shelves, the material labeling is much brighter, reducing the risk of error and increasing the productivity of the warehouse staff. The drawing at the bottom indicates the increased light levels in the aisles, which was a primary concern. The energy reduction was significant utilizing the new T5HO technology, but adding motion sensors in low occupancy areas magnified the savings. As in most warehouse areas, 70% of the space is occupied only occasionally. Motion sensors make that a positive factor in energy savings. Only lighting those areas when occupied had great impact on the overall energy reduction. Overall, utilizing the new T5HO technologies with motion sensors allowed us to achieve our objectives of maximum energy savings and improved light levels
