The project involved replacing various types of existing lighting fixtures with energy-efficient LED alternatives. The primary objective was to enhance energy efficiency and achieve significant cost savings.

Initial Conditions

The building, characterized by its expansive size, required a diverse range of lighting solutions. The existing lighting setup included:

2×4 drop-in fluorescent lights (2×4 PNL’s)
Standard can lights (ECL’s)
6 tube T5 high bays (PHB’s)
T8 2 tube linear strip lights (LSL’s)
Exterior wall packs (WPK’s)
Outdoor flood lights (FL)
These lighting fixtures were prevalent throughout the building, serving various functional and aesthetic purposes.

Upgrade Details

The project involved a complete overhaul of the existing lighting system, replacing all fixtures with LED lights. The details of the LED fixtures used are as follows:

Type of Lights: All fixtures were replaced with LED variants, known for their energy efficiency and longevity.

Number of Lights: A total of 238 LED fixtures were installed.
Specifics of LED Fixtures:
LED Panel Lights (replacing 2×4 PNL’s)
LED Can Lights (replacing ECL’s)
LED High Bay Lights (replacing PHB’s)
LED Linear Strip Lights (replacing LSL’s)
LED Wall Packs (replacing WPK’s)
LED Flood Lights (replacing FL)

Energy and Cost Savings Analysis

The transition to LED lighting brought about substantial energy and cost savings:

Energy Efficiency: LED lights are known for their high energy efficiency, consuming significantly less power compared to traditional lighting solutions.
Cost Savings: The project achieved a remarkable 72% reduction in lighting-related energy costs.
Annual Savings: The financial impact of this retrofit was an annual saving of $34,854.

The lighting upgrade in the 100,000 sq ft building. Not only did it result in significant energy and cost savings, but it also enhanced the lighting quality throughout the building. This case study serves as a model for similar projects, showcasing the tangible benefits of investing in energy-efficient lighting solutions.
