Three scientific-based benefitsof light on lifeThere are two known pathways through which light can affect our well-being:• Visual – The visual cortex, via the photoreceptors (rods and cones) in the retina of the eye• Non-visual – The central biological clock (SCN), via a third photoreceptor: melanopsin

See better(visual)

Feel better(emotional)

Function better(biological)


Optimal support of the two pathwaysaffects people’s work attitude during the day

Visual pathway Non-visual pathway

Visual performance

Visual experience

Acute system Circadian system

Psychological comfort


50% of our brain capacity is used for vision. It costs energy and it needs training.

Visual pathwaySee and experience the world around you


Non-visual pathwayLight regulates our biological clock

Cortisol Melatonin

8:00am noon 6:00pm

Affecting for instance:

• State-of-mind• Sleep Concentration• Alertness• Development/growth

And more indirectly also affecting:

• Immune system• Recovery• Wound healing• Memory• Behavior

Challengesin office environments• The need for flexibility to support all activities

and types of workers: generation X, Y, Z

• Different working styles and needs

• Digital revolution, mobile working, and emphasis on screen work

• Need to stimulate productivity and wellbeing

• Reduction of the office area available per employee while maintaining a high job satisfaction

• Being attractive to work for, increasing employee retention rate


So how do you go forward and create working environment which will help you improveperformace of company and that ensure you keep pace with change and stay competitive?


Did you know?• 90% of the operational costs are staff

related (energy makes up just 1%)

• People in offices are exposed to indoor office light of 500lux as compared to 100,000lux on a sunny day (exposure to more than 1000 lux is necessary for our health)

• We spend 90% of our time indoors

• People spend more time working (36%) than anything else


Different tasks need different lighting conditions. A laboratory study demonstrated that 1000lux supports highly concentrated work while dimmer lighting enhances creative thinking.

Each person’s eyes are unique and perception of light is very personal. Scientific research has proven that proper illumination enhances your near-by vision, and creates ease to your eyes resulting in for instance a better task performance, faster reading speed, lower error rates or less eye fatigue.

Personal control over work stations leads to higher job satisfaction comfort levels and higher perceived productivity. Moreover, some studies indicate that personal control results in energy saving.

Empowerment

of the individual


Personalized lighting

People who appraise their lighting as good will also appraise the room as more attractive, be in a more pleasant mood, be more satisfied with the work environment, and more engaged in their work.”Extract from: “Linking Lighting Appraisals to Work Behaviors” Jennifer A. Veitch, Mariska G. M. Stokkermans and Guy R. Newsham Environment and Behavior2Ol3 45: 198 originally published online 16 September 2011


Proof pointsoffice lighting

• Enhanced concentration and alertness

• Enhanced cooperative behavior and creativity at dimmed light conditions

• Faster reading speed

• Vision support

• Reduced sleepiness during the day

• Increased self-reported performance

• Increased visual performance



Human centriclightingHuman centric lighting brings together an in-depth understanding of user needs, lighting applications and scientific insights to create evidence-based lighting solutions for optimal vision, sense of well-being and performance.

When designing lighting solutions, daylight is always an important sourceof inspiration, as it delivers the winning combination:

• The right light

• With the right spectral content

• At the right time

Appropriate spaces

1. Light intensity

Strengthmatters

• The visual acuity depends on the intensity of light: about 40% increase when going from 50lux to 500lux1

• Enhances concentration and alertness2

• Enhanced cooperative behavior3

and creativity4 at dimmed light conditions

• Faster reading speed5


2. Color temperature

Change color,boost concentration

• Eye becomes tired less quicklyat 6000K than 2700K1

• Alertness and concentrationis improved2

• Reduces sleepiness and increases self-reported performance3

• Enhanced cooperative behaviorat warm light conditions4


3. Light distribution

Createthe right ambience

• Visual comfort is related to the illumination of the space

• Wall brightness enhances the room appearance

• Goven (2010, 2011) found a trend in children’s mood when changing the brightness of the walls and ceilings

Light thatputs you in control

• Qualitative research confirms that personalized light tones and intensities leads to optimal visual comfort1

• Personal control leads to higher job satisfaction2, improved mood and comfort3; higher perceived productivity4

5. Light design


Comfortable lightcreates satisfaction

• Visual comfort is related to the illumination of the space

• Research has demonstrated that satisfaction with lighting contributes to greater environmental satisfaction which leads to a greater job satisfaction1

• Lighting appraisal is linked with organizational commitment and employee engagement2

• Research has demonstrated that lighting appraisal is linked with motivation, work engagement,and productivity3
