Lighting and Human-Centered Design
Today's system of work is task-oriented. Modern lighting and the space in which we perform our professional duties should respond to our needs and motivate us to act.
Employees' expectations change - there are times when the need is full of focus and an injection of energy, but often peace or inspiration is also necessary.
The idea of Human-Centered Design is just reaching out to the users according to the principle that the interiors are to adapt to people, not the other way around.
The key factor here is office lighting, the color, intensity, and quantity of which should be consistent with the properties of natural light being the optimal lighting for human eyesight.
Where did the idea of Human Centered Design come from?
The Human Centered Design concept puts people in the center , their needs, expectations, possibilities, fears and limitations.
The creator of the theory is Donald Norman, who in the 1980s conceptualized a process that returns the end result of a project to the user, which is to serve him without any problems.
Human Centered Design resulted in the Human Centric Lighting (HCL) project, initiated in 2013-2016 by the European Commission, with the aim of broadening the knowledge in the field of modern lighting and supporting practices emphasizing technology development in this area. The findings of these activities define the impact that office lighting has on the well-being and productivity of employees . The existing standards only regulated the level of light intensity, glare or color rendering - they in no way directly referred to the comfort of work of employees, only indirectly spoke about the impact of poor lighting parameters on health.
The main recommendation of the project is that office lighting is optimized for the circadian rhythm . Daylight regulates our biological clock, stimulates our activity or makes us rest. This is because it moves receptors on the retina of the eye that signal to our body at time of day. As the sun moves, also change the color temperature of the light, its angle of incidence, intensity and quantity .
Optimal lighting in the workplace or at rest
Today, we spend a large part of our time indoors, with limited access to natural light. Optimal modern architectural- lighting and office lighting ensuring comfortable working and rest conditions should be as close to daylight as possible, and therefore changeable. Today's technology allows us to adapt the lighting concept to the moment and create fluid lighting conditions.
HCL is to ensure not only the intensity appropriately matched to the current function of the room or the tasks performed by the employee, but also to regulate the color temperature, which is to stimulate the blue light beam, and at night by reducing it, relax. The system can prove helpful in supporting people working in three shifts or frequently changing time zones.
HCL and legal issues
Research on HCL showed that people using the system felt that: work 18% more efficiently, and are full of energy (71% of respondents), happier (78%) and healthier (78%).
The employers themselves benefit from:
- on increasing productivity
- fewer bugs
- or accidents at work
- and most importantly, improving the well-being and comfort of employees.
An obstacle to the introduction of HCL is the lack of legal standards that would regulate the implementation of the system in offices, workplaces or warehouses, and the lack of common knowledge about the benefits of its use. Lighting Europe has set itself the goal of getting regulators to take into account Human Centric Lighting by 2025.
Lena Lighting for the sake of its employees
The idea of Human-Centered Design also guided the design of new offices arranged by the recognized lighting manufacturer Lena Lighting. The needs of employees related to the comfort of work were the most important criterion in interior design. Behind the improvement of well-being and the creative atmosphere is subdued colors, unique design, natural vegetation and, of course, the best quality lighting.
