O’Carroll Engineering Ltd is a metal fabrication that delivers industrial and commercial metalwork solutions, from design through to finish fabrication. They operate double shifts out of an 80,000ft2 facility.
Having identified lighting as a key area for energy reduction, O’Carroll began searching for a suitable system to reduce energy consumption.
O’Carroll set the following goals to achieve with this energy reduction initiative:
Reduced energy consumption and costs
Reduction and/or eliminate maintenance costs
Increased light levels on the factory floor
Having considered a number of potential solutions, O’Carroll identified the Digital Lumens system supplied through PereGreen Energy as the most suitable. PereGreen worked with a team of in-house electricians to complete the project:
Removed 250 existing fluorescent and metal halide fixtures and replaced them with 116 intelligent LED fixtures
Integrated occupancy sensors and daylight harvesting sensors
Integrated energy meter for wireless reporting and downloading of data.
Tailored light levels in particular ‘zones’ based on activity
Full 10 Year warranty, with no limitations on burn hours or switching cycles.
Energy consumption reduced by 78%, representing annual energy savings 116,386 kWh
Total savings will exceed €160,000 over 10 years
Light levels on the work surface increased by 40% on average.
Annual maintenance costs reduced to zero
The facilities team can now accurately report their weekly/monthly consumption
