Savings to Date

By implementing Smart Lighting, UC Davis has reduced lighting energy consumption by about 25 percent since 2007 (this includes the phase 2 work in construction). Our goal is to reduce overall campus electrical use by upwards of 60 percent of 2007 levels. CLTC has calculated UC Davis lighting energy baseline use at 50,400,000 kWh/yr. Below is an interactive info graphic illustrating the projects already completed and the energy savings achieved with each project. Roll over the list below to see the annual energy savings by project. You can also visit our In the News page to learn more about some of the lighting technologies described below.

Phase 1 Building Retrofits

Building Retrofits, Phase 1

Building Retrofits, Phase 1

Phase 1 Building Retrofits work consisted of changing existing lamps to a more efficient type and installing occupancy sensors. These simple and cost effective solutions have resulted in a 50 percent energy savings for the campus while providing a more consistent, uniform light level for the occupants.

Parking Structures

Parking Structures

Parking Structures

Parking structures have been retrofitted with either efficient LED or induction lighting equipped. The system's motion sensors dim the lights by half when people are not present. As a car or pedestrian moves through the parking structure, motion sensors signal the lights to brighten. The LED lights alone provide an estimated 50 percent energy savings compared to energy used by conventional lights. When lights are dimmed by the motion sensors, cost savings are closer to 80 percent.

Parking Lots

Parking Lots

Parking Lots

Parking lots have been retrofitted with induction lighting equipped with bi-level motion sensors. The system's motion sensors dim the lights by half when people are not present. As a car or pedestrian moves through the parking lot, motion sensors signal the lights to brighten.

SLI Phase I

SLI Phase I

SLI Phase I

Phase 1 work consisted of retrofitting restrooms, stairwells and specific incandescent sources across campus to higher efficiency lighting.

Pathways

Pathways & Roadways, Phase 1

Pathways

More than 1,400 energy efficient light-emitting diode (LED) lights located along campus pathways and roadways are managed by a central control hub. The smart network can sense occupants, predict their direction of travel and light the path ahead. The network efficiently manages energy use by dimming lights in vacant areas without compromising safety.

Wallpacks, Phase 1

Wallpacks, Phase 1

Wallpacks Phase 1

101 network-controlled wallpacks were installed on 11 buildings located strategically throughout the main campus. These high efficiency lights are designed to provide higher light quality for significantly less electricity. Additional energy savings can be attributed to occupancy-based controls. Initial analyses suggest an 87% energy savings over the incumbent wallpacks.

Facilities Efficiency Projects

Individual SEPP Projects

Facilities Efficiency Projects

Facilities and DCM worked together to implement a number of small lighting retrofit projects across campus.

Housing Efficiency Projects

Housing Efficiency Projects

Housing Efficiency Projects

Occupancy sensors manage overhead lights and advanced compact fluorescent lights (CFL) to reduce electricity use in campus housing. An online utilities dashboard encourages individual conservation by allowing students to compare real-time electricity use in buildings across campus.

Major Capital Projects

Major Capital Projects

Major Capital Projects

New buildings are outperforming code by as much as 30 percent. Lighting solutions include high efficacy lamps, well-thought out designs, and advanced and adaptive controls.

SLI Phase 2

SLI Phase 2

SLI Phase 2

SLI phase 2 is am ambitious retrofit of 42 buildings across campus totaling 2.5 million square feet and energy savings expected of almost 5.6 million kWh/yr.
