Workers of 24/7 environments that are deprived from sunlight are particularly vulnerable to shift work disorders with a negative impact on workers’ health and productivity. Our light modules can be programmed to follow natural daylight patters to promote the synchronization of the circadian rhythms, enhance alertness and productivity, generally improving the working conditions and quality.
Circadian light cycle can influence alertness and vitality
A 24hours room, control room or operations center is a room serving as a central space where a large physical facility or physically dispersed service can be monitored and controlled.
It may have multiple people on duty at all times to ensure continuous vigilance for 24/7/365 basis.
Examples of control room:
- Industry: nuclear power plants, power-generating stations, Oil refineries, chemical plants
- Transportation facilities: bridges, tunnels, canals, airports, rail operation and rapid transit systems.
- Various military facilities, ranging in scale from a missile silo to NORAD. The term “operations room” is also used.
- IT : Computerized data centers, Network operations centers.
- Administration: hospitals, major research facilities, high security prisons, police or special security jurisdictions.
The design of a control room incorporates ergonomic and aesthetic features including optimum traffic flow, acoustics, illumination, and health and safety of the workers. Workers are isolated during hours from the outside work to keep noise and other distractions to a minimum.
The control rooms or rooms 24h have 3 peculiarities that differentiate them from other working environments.
- Lack of windows or natural light
- Operation during the 24 hours of the day
- Constant use of display screens.
Scientific research suggests that artificial light, or miss of natural light, could have adverse effects on human behavior and health, increasing risks for obesity, depression, sleep disorders and more.
In order to avoid such effects who could impact the concentration and the alertness, and lead to errors or absence worker, it may be possible to adapt the indoor lighting to the human body mimicking the sun and reproducing the Circadian clock..

The goal of this lighting project is to bring natural light into a 24 h room of Repsol in the refinery (plant of Tarragona), during the 8 hours of work day for each shift (morning, afternoon and night), in syntony with the circadian rhythms of the workers.
Move the dynamism of 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 room.
Area 1-2: screen displays; Em = 500 lux
High visual quality: CRI > 95.
Lighting sequence for every work shift:
0-1 hour: ramp up from 3.000K to 5.500K.
Main goal: inhibit the secretion of melatonin, speed up of the concentration y keep alertness state at the beginning of the shift.
1-2 hours: ramp down from 5.500K to 4.500K
Main goal: stay focus and alertness with a warmer light for the rest of the shift.
2-6 hours: “Work light” 4.500K (close to the sun light).
6-8 hours: ramp down from 4.500K to 3.000K.
Mail goal: prepare the worker to leave their work station.
Progressive inhibition of the Blue light keeping the appropriate light on the workspace.
Area 2: Meeting table; Em = 500 lux
High visual quality: CRI > 95.
Static light regardless of the Lighting sequence on the area 1 5.000K
