A recently completed airfield lighting conversion project at the La Crosse Regional Airport saw a 20-percent decrease in both energy consumption and costs in December.
The project resulted in upgrading approximately 80-percentof the airfield to LED fixtures.
This upgrade included rewiring all lights and signs, updating to smaller more energy efficient transformers, converting 852 airfield lights and signs to LED and installing a computer-controlled lighting system.
The airfield saw a 39-percent drop in energy usage in comparison to December last year. The project which cost $1.7 million was mainly funded by state and federal grants and will result in $10,000 to $15,000 per year savings in energy costs alone.
