Human Centric Lighting/2. HCL in the workplace

Human Centric Lighting/2. HCL in the workplace

1. Why is Human Centric Lighting (HCL) so important in the workplace?

Numerous researches have shown that the level of productivity in the workplace is closely connected with the workers’ satisfaction. A pleasant, poorly stressing and adequately equipped workplace not only makes tasks easier to perform, but also increases the workers’ energy and their sense of belonging to the company.

High quality lighting, together with good interior design and an adequate ventilation/air conditioning of spaces are key elements of the ideal office. In particular, a lighting system that applies, even if only partly, the principles of Human Centric Lighting (HCL) allows building a space that facilitates work, improves concentration and protects the health of workers.

How can we achieve these results? The technology currently available in modern lighting fixtures (LED sources, light control systems, easy installation) allows improving the quality of the workplace remarkably, awarding the investment not only through the energy savings guaranteed by modern lamps, but, above all, because it increases the productivity and the satisfaction of workers.

2. How to exploit the advantages of HCL in the workplace?

In detail, workplaces designed according to the principles of HCL take into account of the different effects that lighting has on the human body.

If we consider the fact that lighting should take into account these factors, we can use lamps to achieve a set of goals that will have an impact on workers’ health.

In conclusion, this type of lighting concept creates more comfortable workplaces for users, as well as more functional and better manageable offices for companies.

Over the last few years, the workplace, in fact, changed some of its basic features, thus requiring a new type of lighting system.

For example, the switching from fixed work stations to the new multiuse spaces requires flexible lighting solutions, characterized by a dynamic lighting system that can adapt to different personal needs and different work tasks.

This flexibility becomes even more necessary in co-working offices and in workplaces used by different workers, which must be able to change rapidly based on the needs of different users.

3. How does it comply with lighting regulations?

As for the protection of people’s health, the starting point is the compliance with lighting regulations that set the minimum luminance levels of work surfaces and relevant glare parameters. In this case, we’re referring to the health of our sight, but as we’ve seen earlier, light also has an impact on mood and, in general, on the way our body works.

According to standard EN 12464-1 (“Light and lighting. Lighting of the workplaces”) the parameters to be checked are:

  • Visual task: all the visual elements of the task (dimensions-luminance-contrast-duration).
  • Task area: part of the work place where the task is performed.
  • Immediate surrounding area: band with a width of at least 0.5 metres around the visual task area.
  • Background area: band with a width of at least 3 metres near the immediate surrounding area.
  • Maintained average illuminance: illuminance averaged over a specified surface calculated with a maintenance factor.
  • Illuminance uniformity: ratio between minimum and average values of lighting of a surface.

Other two important parameters are the distribution of luminance and average cylindrical illuminance. With the latter it is possible to assess the space surrounding people to allow good recognition of objects and to favour interpersonal communication.

Maintained luminance must not be below 50 lx. In the areas where good visual communication is important, such as meeting rooms, average cylindrical luminance should not be kept below 150 lx.

Another parameter indicated by the regulation concerns glare, which is a source of possible disturbance and harm for our sight.

The annoying glare produced by artificial indoor lights is assessed through the unified glare rating (UGR). UGR goes from 10 (no glare) to 30 (considerable glare), the lower the value, the lower the glare. Regulations establish the level of maximum glare allowed for different tasks. For example, in industrial applications the UGR should be below 22, in transit areas it should be below 25. In offices and schools the UGR should be below 19.

 

4. Which lighting fixtures can be used to apply HCL in the work place?

To achieve the desired goals, we need lighting fixtures with different features. Designers should use them in the best way possible according to the space’s specific needs. Today the range of fixtures available is vast and includes:

  • Suspended luminaires for direct/indirect lighting of work stations
  • Ceiling/recessed lamps for the lighting of space with a wide distribution of light
  • Direct/indirect lighting lamps for wall washing or indirect lighting
  • Dimmable systems, colour changing, lighting scenario management
