T imelessness, clear, minimalist design as well as compatibility with various furni-
ture systems are the classic demands which many architects and interior desig-
ners make when it comes to office luminaires. They are to go with the interior design
and, ideally, subordinate to the overall plan. That is why luminaire forms are in vogue
which are very minimalist in their design and as flat as possible. Those luminaires
are preferred which have an appealing design and meet the users’ expectations as
well. Today, users almost always want perfect yet as invisible as possible lighting
technology in a well-designed housing. It goes without saying that architects, interior
designers and light planners take this into consideration when they are drafting ten-
ders. These classic demands are more and more frequently complemented with
aspects referring to the wellbeing of the employees at their workstations. In particular
the trend towards biodynamic lighting is intended to promote the health and the per-
formance of the employees. This trend is prompted by the awareness that the course
of daylight regulates people’s natural biorhythm and is responsible for the synchro-
nization of their inner clock. Via the retinal ganglion cells in the eye, light controls the
production of the hormones cortisol, serotonin and melatonin. In the morning, corti-
sol produces energy, serotonin supports interim performance peaks and the sleep
hormone melatonin lowers the activity of many body functions, thus preparing for the
approaching evening and the nocturnal rest already in the course of the afternoon.

The human being should be in the centre of the planning

Taking biodynamic lighting into consideration addresses the fact that, even in case of
nominally sufficient window surfaces, due to the nature of the glazing, the supply of
daylight at most office workstations is not sufficient to fully develop this effect. By
using artificial light which simulates the course of daylight, the employees’ bio-
rhythms are supported in a natural way. For ensuring biodynamic lighting at a wide
variety of office workstations, special luminaires and a corresponding light manage-
ment are needed. The Pulse Net real-time controller by Waldmann, for instance, regu-
lates the light level as well as the light colour for ambient luminaires in the natural
course of the day. With synchronous colour changes, the intelligent control produces

of the employees, norms regarding energy efficiency and the meeting of important
standards complement the catalogue of requirements of planners and clients. The
integration of modern luminaire systems into central building control, the use of LED
technology as well as presence- and daylight-dependent control of luminaires ensure
low energy consumption. Paying attention to the regulations regarding the illumina-
tion of office workstations furthermore guarantees legal certainty. What is important
in this context is the DIN EN 12464-1 on the topic of lighting at workstations which is
the guideline for the illumination of interiors in view of quality and quantity. The ASR
A 3.4 workstation guideline, on the other hand, refers to the employees’ safety and
health protection.

An intelligent system ensures light for all purposes

workstations is already definite or not at the time of the planning. For room-specific
illumination, pendant luminaires or extensive ceiling luminaires produce even light
in the whole space. Thus the workstation equipment can be changed and comple-
mented at any time. If the office structure and the use of the space are already
known, a workstation-specific concept is also feasible. For this, the specific light
requirements at the individual workstations are taken into consideration and free-
standing and desk lamps are often used. For this concept, the Lavigo free-standing
luminaire developed by me and my office together with Waldmann is particularly
suitable. Its so-called Edge Light Technology ensures a homogeneous light-emitting
surface. In addition, the modularly constructed luminaire range offers various
models: It is available as a pendant-, wall-, free-standing or desk-mounted luminaire
as well as in a Twin-T- or a Twin-U variant and can thus be coordinated with different
workstation settings. With various performance levels and biodynamic light, it is
above all suitable for modern office concepts which focus on the wellbeing and the
efficiency of the employees. The luminaire offers an aesthetic overall concept with
timeless design, light efficiency as well current technology and can be integrated into
various work settings. In any one project, for different office spaces such as indivi-
dual-, double- or open-plan offices as well as bench solutions, a system with a con-
sistent design can thus be chosen.
