Mendocino Hall
![Page 3: Mendocino Hall Pilot LED Lighting Project with Advanced ...Mendocino Hall –Pilot LED Lighting Project with Advanced Controls by California State University, Sacramento June 28, 2017](https://reader030.vdocuments.us/reader030/viewer/2022040400/5e6f02f36877fa6ce92dae0b/html5/thumbnails/3.jpg)
Where we were
• Mendocino Hall was built in 1990, with fluorescent T12 lamps.
• A lighting retrofit occurred in 1997 with fluorescent T8 lamps, electronic ballast.

Why we did it
• No means of controlling hallway or stairwell lighting
• We considered installing bi-level fluorescent T8 lamps in stairwells
• We considered installing occupancy sensors in hallways
• In the end, new LED fixtures with advanced controls were selected

Summary of energy saving features of the advanced controls system:• Web-based user interface• Graphical on-screen floor plan provides complete control and
monitoring of all controlled lighting fixtures• Direct power metering at individual fixtures level• Individual fixture occupancy/temperature sensor• Dimming and on-off control• Daylight harvesting• The sensors can be configured in a grouping pattern to allow zone
control
Project Features
The Plan--UTAPS

Project Features…
The Plan--UTAPS
• Light level tuning and power monitoring• Automatic Demand Response (ADR) capable, system will tie into the
existing campus Tridium EMS to respond to a ADR signal from SMUD• Project will be commissioned after installation • All sensors provide occupancy, ambient light sensing, and temperature
sensing with wireless communication
The project is expandable to use the temperature sensors on each fixture to connect to VAV boxes in the future for better occupancy control of HVAC system in the building with hi/lo cut off limits.

• We had numerous lighting fixture and sensor installation problems
• After the installation start-up, we had problem with egress/emergency lighting

• Critical element was to share product technology information with the campus IT department during the project planning process. This will insure IT’s approval and confirmation regarding technology compatibility.
• Select a General Contractor with lighting installation experience.
