Research study Lighting quality perceived in offices Lighting competence originates from many years of experience and extensive technological expertise, to which Zumtobel adds scientifically sound, application-based lighting know-how. In close collaboration with international experts and institutions, Zumtobel is a leader in lighting research, constantly pushing ahead with new product innovations. The most recent findings originate from the global user study on lighting quality perceived in offices, which was conducted jointly with the Fraunhofer Institute of Labour Planning and Organisation...

Differing colour temperature preferences Intermediate and relatively warm light is generally perceived as more pleasant than cool light. In terms of age or sex, tendencies are much less clear and rather emphasise the generally heteroge­ neous distribution of colour temperature preferences. In practical terms this means that flexible luminaires with variable colour tem­ peratures should ideally be used. Preferred colour temperatures Interim data analysis Europe [n = 2148] Broad approval of direct/indirect lighting The research study reveals that more than 60 per cent of all of­ fices are illuminated...

Dr. Ing. Jörg Kelter Fraunhofer Institute of Labour Planning and Organisation "Good visual and lighting conditions help to ensure that employees feel at ease, both physically and mentally. To start with, what is always absolutely necessary is that the lighting does not bother the users. The noble art of truly good lighting solutions is to provide intelligent options for changing or adjusting the lighting and visual situation according to the users’ individual needs and to also deliberately address the emotional level of human sensory perception."

Vodafone Village, Milan | IT Architects: Dante O. Benini & Partners Architects, Milan | IT Lighting design: Dante O. Benini & Partners Architects, Milan I IT Enhancing people's sense of well-being Only happy employees are efficient employees. We encounter a huge variety of different visual stimuli in the course of daily office work. The right lighting is crucial in the process. Light affects almost all vital processes in the human body, and also has an impact on people's performance, health, safety and sense of well-being. For highly motivated and productive people, quality characteristics of...

Enhancing people's sense of well-being Visual performance and visual comfort • People take in 80 per cent of all information via their visual sense • Visual lighting quality is ensured by the quality characteristics of light in line with base levels under applicable standards • In order to provide for optimum vision, the quality characteristics in the lighting concept are evaluated variably, depending on visual task, room utilisation, architecture and individual requirements In conjunction with specific visual tasks and people's visual faculty, light is a visual ergonomic parameter. It influences...

Enhancing people's sense of well-being Biological lighting effect Stimulation in the morning Colour temperature: 5000 K E h * (daylight and artificial lighting): more than 500 lx During the day at sunshine Colour temperature: 4000 K E h * (daylight and artificial lighting): more than 1000 lx Aim: synchronisation of people's circadian rhythm, complete suppression of melatonin release Aim: enhancing well­being through well­matched colour tem­ perature, accordingly warmer light colours during sunshine DIN SPEC 67600 : 2013­04 provides for design reliability and includes specific application recommendations...

During the day with cloudy sky Colour temperature: 6000 K E h * (daylight and artificial lighting): more than 800 lx Getting ready for sleep Colour temperature: 3000 K E h * (daylight and artificial lighting): more than 500 lx Aim: enhancing well­being through well­matched colour tem­ perature, accordingly cooler light colours with overcast sky Aim: synchronisation of the circadian rhythm, no interference with melatonin release, restful sleep To a large extent, biologically effective lighting concepts meet the requirements of the participants in the Fraunhofer study on lighting quality, which...

Enhancing people's sense of well-being Personal control • Modern lighting and room concepts meet people's individual requirements when performing various tasks • Each individual prefers a different luminous color and illuminance level • Innovative control concepts directly at the workstation as well as small, logically assigned luminaire groups are required in technical terms to allow for customisation and achieve energy savings Employees' tasks are becoming increasingly varied, and purely desk­based work is often mixed with creative, communicative tasks. The function of lighting is to also assist...
