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 office concepts.

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.

The 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.

Flexible 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.

Various 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 group communication.

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.

This 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 luminaires.

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.

Firstly, 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 cross-facility solution.

Both can be controlled based on daylight and presence, or only presence, depending on the settings.

Because 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 repeater.
