Villingen-Schwenningen, October 2013: Modern workplace concepts
include flexible spaces that can be adjusted to accommodate changing
uses. This requires lighting solutions that are just as flexible.
Development trends in this context are increasingly moving away from
integrated ceiling-mounted luminaires toward flexible, work station or
zone-related lighting solutions.
In addition, users should be
able to individually influence the lighting at their work stations to
satisfy ergonomic aspects. Influential factors such as different tasks,
personal eyesight and preferences, but also demographic change should be
sufficiently taken into account in this way. At the same time, lighting
is also largely responsible for a comfortable and holistic room
atmosphere. Light is a factor that contributes to a feeling of
well-being and is therefore receiving increasing attention in modern
There, in the exact place where research is
conducted to learn about the effects of different environments and
working methods, the employees themselves are now able to benefit from
the implementation of a future-oriented office concept. The Fraunhofer
IAO has built the "Center for Virtual Engineering ZVE" in Stuttgart. The
new building from star architect, Ben van Berkel from UNStudio
Amsterdam, and the ASPLAN specialist engineers and architects from
Kaiserslautern clearly sets standards. The building received the
Certificate in Gold from the German Sustainable Building Council (DGNB)
for exemplary efficiency, environmental friendliness and conservation of
resources. Of course, the scientists at Fraunhofer IAO influenced the
planning and implementation with their own scientific know-how.
office and laboratory areas are divided into four levels and arranged
around an open atrium. Communication and exchange are particularly
important elements for research – the architecture shall also encourage
these factors. This is why the planners broke though the communication
barriers traditionally anchored in building structures. The atrium and
stairs connect the individual floors and working areas. Workspaces flow
into one another and varying room height provides views and insights
between the floors.
The provided infrastructure at the work
stations is exactly customized to the individual requirements. Different
characteristics of project work require diverse working possibilities.
work stations make it possible to physically integrate different
knowledge bearers depending on the project. Different working situations
are also taken into account by offering the scientists rooms to retreat
to, areas for undisturbed work in small groups, for spontaneous
meetings or planned discussions.
All this requires flexible
lighting solutions that can be adjusted to individual requirements
depending on the working situation and the work station user. As a
result, appropriate lighting solutions are implemented in the building.
manufacturers equipped different areas in the ZVE with innovative
lighting solutions. A solution from Waldmann is being used on "Level 2."
It combines efficiency, lighting quality and convenience. The
combination of ATARO LED free-standing LED luminaires with both the
PULSE HFMD and PULSE TALK lighting management systems makes it possible –
with a daylight sensor system, presence sensor technology and wireless
The flexible free-standing luminaire
solution can be adjusted to new work station configurations time and
again. In addition, the luminaires can adapt their light to changing
presence situations in the office at any time. The technology focuses on
people and their needs. Lighting quality and lighting ambiance improve
the quality of the workplace.
If the office is completely full,
each work station features individually desired work lighting. If only
individual employees are present, the level of lighting is reduced to
basic lighting in the places where there are no longer people. This
reduces energy consumption without forgoing a pleasant lighting
atmosphere. If an employee returns to their station, the surrounding
lights adjust accordingly. The lighting adjusts itself to their
presence, even while they are on their way to the work station.
works because the luminaires are assigned to groups. Within these
specifically defined groups, they exchange presence information and
generate the appropriate lighting scenario.
The PULSE TALK
lighting management system makes efficient area light management
possible and distinguishes itself first and foremost with its simple
operation and installation. The luminaires learn automatically. Software
is not required for assignment, so new configurations are simple. Each
assignment to an area and a group can be clearly read or changed
directly on the module. In addition, the lighting at the work station
can be changed individually, without influencing the surrounding
In comparison to similar solutions, PULSE TALK uses
the EnOcean wireless standard for communication. This makes the system
interoperable, not an island solution that can only be used for
communication between the luminaires. Using an external wireless switch,
certain luminaires can be turned on/off or dimmed, together or
individually. Additional room functions can also be realized.
one luminaire in the group can take over the master function and the
corridor lighting, which is equipped with an EnOcean-compatible wireless
actuator, for example.
Secondly, it is possible to further exhaust
energy-saving potential by using an EnOcean Gateway to connect to
building automation. This makes it possible to use the presence
information of the luminaires in other ways. For example, the air
conditioning can be controlled according to zone and presence as a
Both can be controlled based on daylight and presence, or only presence, depending on the settings.
the system works in two directions, the building or room automation can
also influence the luminaire network. If the range should ever prove
insufficient, PULSE TALK even supports the wireless network as a
