Repsol 24 hours control room

The goal of this lighting installation was to bring natural light into a 24-h control room of the Repsol oil refinery plant located in Tarragona, Spain. The circadian lighting solution installed used downlights with LEDMOTIVE VEGA 10 spectral control technology inside to follow the circadian rhythms of the workers along a cycle of 24 hours.

The goal of this lighting installation was to bring natural light into a 24-h control room of the Repsol oil refinery plant located in Tarragona, Spain. The circadian lighting solution installed used downlights with LEDMOTIVE VEGA 10 spectral control technology inside to follow the circadian rhythms of the workers along a cycle of 24 hours.

This advanced lighting system reproduce the dynamism of the natural light into the work environment, to increase the feeling of well-being and provide a suitable atmosphere by increasing the performance, concentration and motivation of employees.

In order to carry out the light analysis and to design the most optimal illumination for this type of working environment, a balance has been taken between the working area to be illuminated, the intensity of light and the distribution of the luminaires inside the control room.

Lighting configuration:

• Screen displays withilluminance levels Em = 500 lux
• High visual quality with color rendering index: CRI > 95.
• Lighting sequences for every work shift: morning, afternoon and night changing from 3000 K to 5500 K

• Sequence1: light spectrum changingfrom 3.000 K to 5.500 K with the main goal to inhibit the secretion of melatonin, speed up of the concentration and keep  alertness state at the beginning of the shift.
• Sequence2: ramp down from 5.500K to 4.500K with the main goal to stay focus and alertnesswith a warmer light for the rest of the shift.
• Sequence3: light spectrum stabilized with CCT 4.500K close to the sun light.
• Sequence4: ramp down from 4.500 K to 3.000 K toprepare the worker to leave their work station. Progressive inhibition of the Blue light keeping the appropriate light on the workspace.

Final results:

• Improvement in worker productivity due to the high quality of the circadian lighting solution.
• 65% reduction in display screen reflections in the control room
• Tunable lighting solution that avoids forcing the eyesight or generating glare discomfort
