8. RECOMMENDED ENERGY EFFICIENCY PROJECT DESCRIPTIONS<br />

The projects identified in this SEP are described below, and the project titles are referenced for<br />

each applicable project on the individual Project Summary pages later in this report. While<br />

there are often alternative technologies or approaches to projects that can be considered for a<br />

given retrofit, this report’s recommendations focus on projects that can be implemented cost<br />

effectively with available technologies and methods. Where appropriate, alternate approaches<br />

and considerations are discussed for projects considered but not included as a recommendation<br />

of this SEP.<br />

For ease of reference, all SEP projects have been assigned an SEP ID Number. The SEP ID<br />

number consists of one letter followed by four digits, and is a unique number that will help easily<br />

locate projects. The SEP ID number has been included on the Building Overview pages later in<br />

this report, and the Project Summary section of this report is organized by SEP ID number to<br />

allow easy location of a project.<br />

8.1 Lighting Projects<br />

The <strong>Strategic</strong> <strong>Energy</strong> <strong>Plan</strong> includes a projection of the magnitude of lighting energy efficiency<br />

projects on the campus. The plan addresses interior fluorescent building lighting and interior<br />

HID lighting, as well as parking garage lighting and some outdoor lighting.<br />

8.1.1 Lighting Project 1. Interior Linear Fluorescent Lighting<br />

The standard project for fluorescent light fixtures is to use a state of the art lamp and ballast<br />

combination to limit each pair of fluorescent lamps and ballast to approximately 42 watts. This<br />

can be achieved through different combinations of lamps and ballasts according to each<br />

individual campus’s preference.<br />

Unless a campus expressed a specific preference, the default retrofit used for the analysis was<br />

to replace existing 32W T8 lamps and any remaining T12 lamps and their associated ballasts<br />

with 28W T8 lamps and premium efficiency ballasts with low ballast factors. The resulting<br />

fixtures typically operate at slightly lower light levels relative to the existing levels, but their<br />

improved color rendition has been shown to increase or maintain the perceived light level.<br />

<strong>Campus</strong>es can factor in color temperature, lamp life, lamp standardization, ballast<br />

standardization and a number of issues into their design.<br />

<strong>UC</strong> Santa Barbara, has chosen to install dimming ballasts in many applications instead of basic<br />

ballasts. This involves extra expense and operating complexity, but the potential for greater<br />

energy savings as well. The higher cost and savings are documented in the analysis.<br />

8.1.2 Lighting Project 2. Interior Lighting Controls<br />

Another standard lighting project is to install occupancy control in rooms that do not currently<br />

have occupancy control. The analysis accounts for the fact that most campuses already have<br />

occupancy sensors in some buildings, primarily in offices and classrooms. Some campuses<br />

have early generation occupancy sensors in classrooms, many of which have been disabled at<br />

the request of faculty and staff. Newer “dual technology” occupancy sensors, which detect both<br />

motion and heat, are much more reliable than the older technology, which was prone to turning<br />

off lights when occupants were not moving.<br />
