  1. Laboratory Lighting Controls Upgrade • New Laboratory Building Biological Sciences 3 • Beat Title 24 Energy Standard by 20%+ • Challenge to reduce annual energy consumption from lighting by ~50% • Extremely low Lighting Power Density (LPD) LPD = Lighting Watts / Square Foot • Lab Environment with ~50 Foot-candle Requirement • Reducing true LPD not a probable option

  2. Lab Area LPD = 1.1 BEFORE Lab Prep LPD = 0.9 Prep Room LPD = 2.0 Corridor LPD = 0.6

  3. Manual Switch to Occupancy Sensor A-B CIRCUITING 50% Auto On - Manual to 100% - Auto Off

  4. Auto on to 50% Light Level

  5. Lower Blinds to Allow for Daylighting

  6. Photocell to Control Window Fixture BUTTON PHOTOCELLS

  7. Fixture Closest to the Window is OFF

  8. Lab Area SAVE +50% AFTER Lab Prep SAVE 40% Prep Room SAVE +50% Corridor SAVE +50%

  9. Summary • Project Is Scalable (floors, buildings, campuses) • Simple Payback Period in the 2.3 to 3.4 year range • Savings Based on Controls not LPD! • Consider under cabinet task lighting at the work surface to augment overhead lighting • Consider perforated blinds to increase light and reduce glare through “views” portion of fenestration

  10. LIGHTING • Lighting should be as flexible as the possible • Provide task lighting when additional illumination is needed • Encourage occupants to be conscious of their lighting needs • Do not discount the synergistic savings of heat produced by over illuminated spaces

  11. LIGHTING 208,561 kWh/year 94,753 kWh/year Results in a savings of $11,897 per year at $0.105 per kWh

  12. LIGHTING Perforated Window BlindsMake use of daylighting without the glare

  13. LIGHTING Lab areas within 15’ of the window line and all private offices and conference rooms are equipped with automatic daylighting controls

  14. LIGHTING Auto on to 50%, Manual on to 100%, Auto off Sequence Zoning Lighting is controlled per lab bay not per lab to maximize savings

  15. LED Task Lighting Magnetically mounted LED Task Lighting
