Continuing the quest for energy savings

California State University, Dominguez Hills (CSUDH), a public university in Los Angeles, is a major consumer of energy and natural resources. The university has made it their responsibility to be a wise steward of scarce resources by reducing the use of non-renewable resources and increasing energy efficiency. As part of the large CSU system, this responsibility also includes promoting continued economic and ecological viability in California.

The team at CSU Dominguez Hills turned to ENLIGHTED to help analyze the possible energy savings using occupancy sensors and lighting controls by starting with just one area on campus that was being manually controlled.

The initial pilot installation of 276 hallway sensors in Welch Hall and the South Academic Complex, and188 sensors in Natural Sciences and Mathematics and La Corte Hall.

The savings in the pilot areas amounted to 201,436 kWh annually, saving the university $26,289 in electricity costs over that same time period. Additionally, Southern California Edison issued a rebate of $51,565 for the campus energy savings brought about by the Enlighted Advanced Sensors. The successful outcome at Welch Hall and Natural Sciences and Mathematics Hall, and La Corte Hall led to further installations covering 90% of the campus and over $1,000,000 in energy savings!

The university chose to move forward with Enlighted’s platform because its advanced sensors provided several unique benefits to the university citing the following:

  • Ease of implementation: Sensors communicate over a wireless network, enabling a relatively simple upgrade of CSUDH’s existing fixtures.
  • Cost-effective solution: The sensor units could be easily installed, commissioned, and serviced by the facilities management team at the university, making the solution affordable to implement and maintain going forward.
  • Highly intelligent sensors: Advanced sensors make control decisions locally at each fixture, adjusting light levels by sending information to the driver of the host fixture. Lighting level decisions are made by: Daylight harvesting, Motion sensing, and Digital PIR sensing.
