Client:
Sunrun
Project Type:
Facility LED High Bay Lighting Installation
Electrician
Ben Moore
Challenge
High energy costs and frequent maintenance issues with outdated lighting systems in a 25,000 square foot warehouse.
Solution
Comprehensive lighting upgrade to energy-efficient LED fixtures and installation of motion sensor systems.
Results
Cost Savings
- Energy Cost Savings: Assuming $0.18/kWh
- Annual Cost Savings: $10,819/𝑦𝑒𝑎𝑟
- 60,105.6 kWh/year×$0.18/kWh
Maintenance Reduction
- Old System Lifespan: Approximately 15,000 hours for metal halide
- New System Lifespan: Approximately 50,000 hours for LED
- Maintenance Cost Savings: Significant reduction in maintenance costs due to the longer lifespan of LED fixtures and reduced frequency of bulb replacements.
Energy Savings
- Old System Consumption: 126,144 kWh/year: 72 fixtures×400 watts×12 hours/day×365 days/year/1000
- New System Consumption: 66,038.4 kWh/year: 72 fixtures×210 watts×12 hours/day×365 days/year/1000
- Annual Energy Savings: 60,105.6 kWh/year: 126,144 kWh/year−66,038.4 kWh/year
Improved Lighting Quality
- Old System Lifespan: Approximately 15,000 hours for metal halide
- Lumens: 28,560 lumens per fixture for new LEDs
- Color Temperature: 5000 Kelvin, providing bright, daylight-like quality
- Productivity: Enhanced visibility and safety for warehouse employees, leading to an estimated 15% increase in productivity.
Implementation
Assessment
Conducted a thorough audit of the existing lighting system, identifying areas with the highest energy consumption and maintenance needs.
Design
Developed a customized lighting plan that optimized fixture placement for maximum efficiency and coverage.
Installation
Replaced 400-watt metal halide fixtures with 72 new 277V, 28,560 Lumen, 5,000 Kelvin, 210-watt LED High Bays. Installed motion sensors to ensure lights are only on when needed, reducing energy consumption.
