10. EXAMPLE ENERGY EFFICIENCY PROJECT
FACILITY LIGHTING
TWO PATHS TO FOLLOW
SIMPLE ONE FOR ONE REPLACEMENT ENGINEERED UPGRADE
• No change in light levels • Correct light levels for the task
• No repositioning • New fixture locations where appropriate
• No interaction with other controls • Occupancy/daylight/total building controls
• Often a single fixture type • New fixtures to meet new needs
• Lighting simulation study
Example Result Example Result
– Spend $200,000 – Spend $350,000
– Save $80,000 per year – Save $180,000 per year
– 2 ½ year payback – 1.9 year payback
The Engineered Upgrade saves $100,000 more per year
(Equals additional profits from $3 million in new sales)

11. EXAMPLE ENERGY EFFICIENCY PROJECT
FACILITY LIGHTING
TWO PATHS TO FOLLOW
