  3. Energy & Economics • 1,170,000 kWh saved annually • 331 kw saved • Cost of construction was $1.7 million • 34% of cost was for ESCO management fees • 13 year payback without incentive • Financed through UC/CSU partnership program • $281,000 incentive funding from partnership

  4. Lighting Strategy • Cost effectively reduce energy and improve lighting quality through combining improved fixture design with 5,000 k lamps, 85 CRI, and LPF ballasts in fluorescent fixtures. • Option 1: replace fixtures (not cost effective) • Option 2: use retrofit kits and replace lamps and ballasts (barely cost effective) • Eliminate LPS and HPS lamps, and replace with fluorescent. • Add occupancy sensors where appropriate.

  5. Lamps Phillips TL850 Alto plus low mercury lamps • 36 month warranty • 5,000 k • CRI 82 • 42,000 hours rated life

  6. Ballasts GE Ultramax and Ultrastart high efficiency • Multi-voltage handles 120 to 277 • Anti-Striation Control • Cold temperature starts at -20 degrees • Low ballast factor .77 • 5 year warranty • Ultramax in hallways • Ultrastart in classrooms and offices

  7. Retrofit Kit A.L.P. Lighting Universal Adapter Bracket System Direct / Indirect Lighting Installs in 15 minutes Installed 2368 2X4 kits and 606 2X2 kits

  8. Classroom Lighting Changed from 3 lamp to 2 lamp, and from 4100 k to 5000 k Reduced from 84 watts to 56 watts per fixture Changed from 33-55 FC to 20 – 25 FC High efficiency ballast upgraded Gen1 to Gen3, low ballast factor Direct / indirect Better light distribution No cave effect, reduced hot spots

  9. Corridor Lighting Changed from 3 to 2 F32 or F17 lamps per fixture 2X2 F40 Utube Wall sconces similar issues 40 w BIAX to 2 (32w) or 1 (17w) F17

  10. Stairwell Lighting LaMar Occusmart 1 F32 on occupancy + 1 F17 emergency power

  11. Office Lighting 5,000 k 17 FC to 25 FC fully lit 9 FC in this photo (preferred by users) Reduced from 84 watts to 56 watts per ceiling fixture 6 watt LED task lighting (only 16 requested)

  12. Low Bays Lighting Before New Lighting

  13. Outdoor Lighting Before New Lighting

  14. Parking Lot Lighting Before New Lighting

  15. Walkway Lighting Before New Lighting

  16. Ballard Lighting Replaced 100 indirect HPF lamps with 25 watt CFL
