During the working day, lighting supports employees in their work. The visual, biological and emotional effects of lighting should be considered. Modern lighting concepts make working easier: good lighting increases concentration, reduces fatigue and is bright enough for all visual tasks, including tasks performed by aging employees. The minimum value for brightness at eye level should be met by a sufficient vertical lighting level. Higher lighting levels and the right spectrum composition help to maintain the performance for a longer period of time. A study by CBRE in offices showed an improvement of 12% in task performance with circadian lighting.

The lighting scheme includes a jarring dose of comfortable bright light first thing in the morning and various fluctuations throughout the day, such as another boost after lunch.
While the lighting is designed to complement people’s natural circadian rhythms, employees may, at any time, override the light settings, tailoring the light to their needs or specific work tasks.
High workplace satisfaction positively correlates with high employee engagement. Independent research reveals that workplace satisfaction makes good business sense.
This is one of the first large scale projects equipped with dynamic lighting in Europe: 1000 LED luminaires and downlights change brightness and colour temperature throughout the day to support the vitality and circadian cycles of 550 employees on site, across 10,000 square metres.

The lighting is designed to meet the various and changing visual needs of the people in the space.  The lighting therefore creates a dynamic experience through modulating lighting levels and focuses on creating uniform lighting levels only where needed. Wherever appropriate, the lighting levels are reduced to a minimum in order to create a perceptual pause and thus allowing or the areas with higher lighting levels to be highlighted without need for excessive illuminance. This also makes the space more visually appealing and less tiring and dull.
All lighting fixtures are chosen and placed with a particular task in mind, thus eliminating the element of random light that only adds to the electrical bill without creating any form of value.

Spotlights on pictures between windows:
highlighting the photos and adding colour to the appearance creating a softer appearance of the luminant windows - daylight and electric light in harmony
Individual task lighting enabling personalized lighting levels.
High uniformity and right amount of illuminance on the assigned working plane.
Greatly reduced amount of lighting solely intended to illuminate the floor.
Vertical illuminance on the back wall creating a bright appearance.
All lighting fixtures offer
- a high level of visual comfort free from unwanted glare.
- an excellent colour rendering.
Did you know?

Going outside for a short, 15-minute walk helps beat post-lunch laziness.

Even on a cloudy day, you can get up to 10,000 lux when outside, whereas in an office you will typically only get 500 lux.
