UCSC Facilities / Green Campus Collaboration
Projects

• 2007 Bi Level Stairwell Lighting Project
• Interns did site walks of potential building
  stairwells around campus.
• Counted potential fixtures
• Recorded type of fixtures
• Took photographs
• UCSC analyzed data and developed a scope of work
  and submitted application to PGE for incentive
  funding
• Project completed Summer 2007
• 2009
• Occupancy Sensor / Daylighting Lighting Retrofit
  Project
• Outdoor Lighting Retrofit Project
• HID (High Intensity Discharge) to LED or CFL
  technology
• Architectural Impact

Bi Level LED Outdoor Lighting Project

• UCSC is a rural campus
• Buildings spread out across campus
• Numerous path lights
• Low traffic at night
• Existing outdoor fixtures
• Globe HPS fixtures
• Shoebox Fixtures
• Post Op Fixtures
• Fountain style Fixtures
• Replace with LED equivalent fixtures with
  Infrared Sensors
• Unoccupied mode 50 output
• Energy Savings
• Safety Feature Fixtures will light up when
  someone approaches

5
Proposed LED Fixtures

• Save Energy, Money, and
• reduce CO2 Emissions
• 18 or 55 watts depending on fixture
• No toxic chemicals, fully recyclable
• 100,000 hour life 30 years
• Reduced maintenance
• costs

6
LED Light Quality

• Provide better light quality for improved
  visibility and safety
• Minimal lumen depreciation

7
BiLevel

• Bi-Level LED pathway lights use motion sensors to
  go from full power in the occupied state to less
  than half power in the non-occupied state.

8
Light Pollution

• ¾ of Lights on Campus are Globe shaped
• Proposed Lights are designed to reduce light
  pollution
• Light Pollution disturbs night time pollinators
• Disrupts stargazing

The Green Campus Program's Role
Green Campus Program's Role

• Site Survey
• Fixture Types
• Fixture Counts
• Data Logging
• Fixture Locations
• Photographs
• Maps

• Energy Calculations
• Estimate costs payback

10
Maps

• Handheld GPS to acquire coordinates of each
  fixture
• Google Earth and Campus Maps for background
  layers
• ArcGIS to produce final Maps

11
Metrics

• Estimated Annual Savings
• 60,000 kWh
• 15,000 Energy Incentive from PGE
• 30,000 pounds of CO2
• Reduced maintenance costs
• LED Fixture Life gt100,000 hr
• Traditional HPS 2-3 yrs
• Cost
• Approx. 1,000 per fixture
• or 137,000 for 137 fixtures in 3 pilot areas
• Payback 9 years

12
Next Steps
Next Steps

• Test different fixtures and wattages
• Install LED fixtures at Pilot Areas
• Expand to include all lights at UCSC and entire
  UC system
• Create informative displays
• Get feedback from the campus
