I want to concentrate well

Shortage of daylight causes concentration problems

Shortage of daylight causes concentration problems

Employee health is increasingly a priority. Daylight entry into buildings and good lighting contribute significantly to this. Employees are too often in buildings where too little or no daylight enters. Artificial lighting supplements this in order to see well. However, this has little influence on our biorhythm. A shortage of daylight can cause concentration problems, a reduced alertness, a disturbed sleep/wake rhythm and an increase in the risk of winter blues occurring. The extent to which light influences this depends on the illuminance, duration of illumination, timing and the spectral distribution.


Project analysis

The use of biodynamic lighting systems is hot. Installing these systems without thinking is not the norm in our opinion. FluxPlus makes an analysis of the current lighting or the lighting that has yet to be installed. In addition to an analysis, a functional Program of Requirements (fPvE) can be drawn up by means of interviews. This provides insight into the vision, mission and strategy. In addition, it becomes clear what requirements, wishes, opportunities and especially expectations are. The results are tested against the applicable standards and recommendations for healthy lighting in offices according to the WELL Building Standard and NEN-EN 12464-1 (indoor workplaces).

Biologically, physiologically activating daylight

  • positive influence on alertness, concentration, presentation and mood
  • reduces fatigue and (social) jet lag
  • increases productivity
  • improves sleep/wake rhythm
  • lowers depressed/depressed feelings (winter blues)

Design + advice

Creating an integrative lighting design (good light for vision, biorhythm and well-being) and lighting scenarios is tailor-made. FluxPlus makes a spot plan where workplace lighting, mood lighting and/or biodynamic lighting can be applied. A light design with associated light calculations is then made. In addition to the horizontal illuminance (vision), the vertical illuminance is also calculated (biorhythm). FluxPlus advises which luminaires are most suitable for each project. Depending on the technical possibilities, advice will be given on the control of the lighting. A lighting scenario is drawn up based on working hours/breaks.

Support implementation

Achieving healthy lighting in a room where people work for a long time is not easy. There is a great deal of uncertainty and ignorance about the advantages and disadvantages for employees, about energy consumption, the technical (im)possibilities and the costs that such an innovation entails. Many manufacturers and installers also believe that they have the necessary knowledge in this area, whereby they do not pay sufficient attention to the requirements and wishes of the end user. FluxPlus supports and advises in the implementation of biodynamic lighting from the start of the project to the final commissioning (turn-key solution).

Knowledge transfer

FluxPlus’ knowledge and experience can be transferred to the personnel who will be working with the biodynamic lighting. It is important to know why biologically activating light is in their favour, but also what the negative aspects are of using it at the wrong times. Attention is also paid to hormonal and metabolic processes related to the biorhythm.


We are regularly asked whether the application of biodynamic lighting really works. Feedback from our own employees is often sufficient, but we can also commission an effectiveness study or a feasibility study. Where possible, we also try to find out whether subsidies exist to support a project. Experience shows that many subsidy options remain unused on the shelf.
