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

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
