Employees are our most important resource. 80–90% of operating costs in a typical business are employee costs. The lighting quality in offices can positively impact the wellbeing of employees, increasing their productivity and reducing sick-days per employee. The Global User Study on Lighting Quality Perceived in Offices shows that people want controllable, personalized and dynamic lighting in their workspace. The Daylighting in the Workplace (Elzeyadi, I 2012 ‘Salutogenic Environments: Health and Healing Impacts of Daylighting in the Workplace’, World Health Design Journal) study shows that perceived better daylighting quality in offices can reduce employee sick days by 2 days per person, per year.
Right Light in Time
The TunableWhite technology, imitating the dynamics of natural light by changing the colour temperatures indoors according to the movement of the sun, in the right combination with higher lux levels and a perfect balance between direct and indirect components, are bringing the benefits of Mother Nature into your office.
The changing angle of the sun relative to the earth results in a varying colour temperature of sunlight throughout the day;
warmer light (3000K) during sunrise gradually changing to cooler light during midday (6000K) changing back to warmer white in the evening (3000K) for better sleep at night. The color temperature and intensity of the light is responsible for setting the human circadian rhythm and regulating the sleep-wake cycle. Tunable White

The „natural“ timeline follows daylight dynamics to synchronize the circadian rhythm, enhance wellbeing and ensure a sound, restful sleep at night. The colour temperature gradually changes over 9 hours from warn white (3000K) to cool white (6000K) and back to warm white in the evening, thus mimicking the dynamics of the sun.
People might typically drink a cup of coffee in the afternoon. The “boosting” timeline can be used to provide a burst of stimulation light in the afternoon for added activation. Therefore the light colour temperature changes to cool white (5000K) for one hour in the afternoon and gradually back to warmer colours to ensure a restful sleep at night.
Shift working timelines are based on studies that support rather than shift the circadian rhythm, ensuring alertness during work at night but also a sound sleep after the shift work is finished. The Light for the night shift study from the Research Centre for User-Centred Technologies (FHV) shows that working with the natural rhythm with the right lighting rather than shifting it, throughout the night shift is more beneficial to the wellbeing of shift workers.
Right Light for Task
Lighting that reacts intuitively and automatically to your needs, whether you are at your desk, in a discussion or presenting to an audience. Autonomous lighting in conference rooms, meeting and break-out zones provides a dynamic yet optimized atmosphere. Smart sensors and controls work together for comfort and energy balance by automatically optimizing the lighting, based on presence and task.
Right Light for You
We are all individuals with personal preferences. Simple lighting controls with an easy to use interface makes it possible to change and set the lighting scene to exactly your needs, in your workspace.
The workspace is where employees connect, collaborate and create inspired solutions. Therefore the look of the workspace needs to fit the needs of the people in it and reflect the values of the company. When it comes to identification with a cause, an objective or an enterprise, a strong mission statement or symbol (e.g. architecture) is of vital importance.
Activity Based Lighting for offices by Zumtobel
Luminaires, sensors and controls seamlessly integrate to create and enhance user experience. Be it intelligent sensors that create the right lighting scene for a task, easy personal control of luminaires or looking further into the Internet of Things – connectivity in a workspace is all about an ecosystem.
Daylight is the original light source, connecting with people through an elementary relationship and shaping human behaviour since the dawn of time. It may not necessarily be visible or even noticeable, but light defines how we experience the world through its many delicate facets, such as light colours, shadows, contrasting intensities and changing directions. However, today people in industrialised countries spend around 80 per cent of the day inside – with reduced exposure to the essential dynamics of natural light. Lighting technology innovation in recent years has made major strides in terms of generation, distribution and control, greatly expanding the raft of possibilities offered by artificial lighting design.
Wellbeing in office spaces is enhanced by holistic lighting ecosystems. Active Light is linked to daylight dynamics, actively supporting the natural bio rhythm and seamlessly ensuring maximum visual comfort for tasks. Such human centric lighting solutions bring people together and promote creativity, as they are effortlessly personalized, with the individual always at heart.
The right lighting level can best be determined by the individual’s visual ability and the task itself. Moreover, basic planning parameters and current standards for workplaces must be taken into account. “The sun rolling high through the sapphire sky, keeps great and small on the endless round. It’s the circle of life.” (Elton John) The position of the sun, the reflective light of the moon and the weather determine the light intensity over the course of a year, a month and a day.
Light is a tool for architectural design. By varying luminance and light distribution the general atmosphere of a space can shift instantly, which can have a major impact on communication, creativity and easing of tension. The course of the sun in a day or a season has influenced the precise location of human settlements since the beginning of time. The sun helps create dynamic silhouettes so that shadow-free hours with a cloudy sky seem rather dull in comparison.
The human body reacts to the colour temperature of light. While cooler, blueish light colours activate, warmer, reddish light colours have a soothing effect. A study carried out in cooperation with the Fraunhofer IAO shows that a user’s colour preferences vary depending on age, working hours and individual needs. Sunrise or sunset, a rainbow, the subtle interplay of light and water, the light reflected by a rich autumn forest or a vivid snow scene – nature’s light adds a colourful, emotional quality to our lives.
By mimicking the natural dynamics of daylight, artificial lighting complements and supports one’s internal clock. Originally, phases of activity and recreation were defined by the natural course of light. It wasn’t until the development of more advanced sources of artificial light that humans began to shift nature’s dimensions of time, resulting in both positive and negative consequences.
