Conveyor and processing systems for the print media industry are manufactured, cabled and tested in Ferag AG’s machine shop. The lighting in the machine shop was timeworn until just a few months ago. Insufficient light, frequent lamp failures and awkward maintenance often disrupted work and incurred considerable costs.
The chief argument in favour of lighting refurbishment was the need for optimum lighting conditions. The procurement and maintenance costs as well as the energy consumption of the old luminaires were also no longer acceptable. The new solution was consistent with the company’s basic principles of using resources carefully and being committed to sustainability.
The various task areas in the machine shop and a desire to integrate daylight provided the starting point for lighting design work. There are CNC machines with displays in the front part of the shop, and mechanical plant components are assembled elsewhere. The TECTON continuous-row system uses various optics to cater for the needs of the various visual tasks. A DIMLITE lighting control unit compensates for changing amounts of daylight over the course of the day. Look Out sensors facing the glazed frontage measure incoming natural light. If daylight fails to provide the predefined brightness, luminaires are dimmed up to an appropriate level. This improves lighting comfort and minimises energy consumption: lighting refurbishment will pay for itself within about two years.

Technology is meant to help, not hinder
What do you get when the client comes from a scientific, technical background, the interior designer likes to be provocative and the hotel operator is an experienced old hand? A hotel like the Belvoir. The hotel echoes the shape of a nearby glacier and offers magnificent views across Lake Zurich.
That is the yardstick by which the lighting control system is also judged. The client and the future hotel operator both assumed different roles several times during the planning phase: the role of guest in order to test user-friendliness, or the role of operator with the primary concern being low maintenance costs, energy savings and simple maintenance.
ZBOX is is a self-contained system that controls one hotel room and responds flexibly to requested changes. CIRCLE multifunction switches make it clear to guests immediately how to operate the system. Guests can set ready-made lighting scenes at the press of a button. The horizontal shutters are controlled by a central daylight measuring head but can nevertheless be raised or lowered manually. Automatically closed blinds prevent the build-up of heat when a room is unoccupied. Inserting a key card automatically opens the blinds and activates the "welcome" lighting scene. A morning, midday and evening scene is programmed for the restaurant; their brightness is easily adjusted by touching the iPod-like CIRIA user interface. The lighting control systems, emergency lighting system and emergency luminaires have been provided by a single supplier. The fewer interfaces there are, the easier and quicker it is to put a system into service.

The restaurant in Kassel was extensively renovated in order to give the slogan "Nordsee. The alternative" added impetus. In the course of interior refurbishment, the lighting too was completely modernised.
The entire restaurant was converted to LED, and colour temperature in the dining area are inspired by the model that is provided by nature. The lighting control system was commissioned by Zumtobel Service, who also familiarised staff with the innovative lighting concept and showed them how to operate it.
From a lighting viewpoint, morning starts by simply turning a central key-operated switch. The right light and high illuminance levels for restaurant prep work are immediately available. For diners, the day gets off to a start with warm colour temperatures reminiscent of the rising sun. At midday the restaurant is bathed in gleaming, cool light. In the evening, the EMOTION lighting control system paints a marine sunset scene: reddish hues invite diners to savour their evening meal at leisure. Recessed LED luminaires and LED light coves provide refreshing accent lighting regardless of the time of day. In kitchen areas, brightness levels rather than the light colour of the general lighting are changed to suit the best lighting situation for any particular task. The LUXMATE EMOTION lighting control system thus combines the benefits of LEDs, which include, among other advantages, low heat emission and therefore reduced expenditure on food refrigeration, with excellent hospitality. Operating convenience can also be taken for granted when using EMOTION. When the restaurant closes in the evening, turning the key-operated switch illuminates the restaurant in a red light which matches the firm’s corporate design.

The workplace of the future is already a reality at the head office of Hannoversche Lebensversicherung AG. This highly efficient building with triple glazing and thermally insulating façade elements uses geothermal probes, heat pumps and district heating to meet its considerably reduced energy requirements.
The client wanted a highly efficient office building that provided maximum flexibility and was ideally prepared to cope with a large number of anticipated alterations in room layouts. It was looking for a company that supported lighting management externally, took over facility management and performed maintenance.
All the luminaires and blinds in the three-part building complex are controlled by a TCP/IP-based LITENET lighting management system. All settings and changes to the system can be made from a central location. This was achieved by integrating the system into a building-wide OPC visual display. Individually addressed DALI luminaires make it possible to respond flexibly to changes. Available daylight is measured by a central daylight measuring head. Exterior blinds with a light guidance function are adjusted appropriately depending on the position of the sun. The required dimming level of each individual luminaire to ensure constant lighting levels is recalculated and set at one-minute intervals. Presence detectors reduce the operating hours of luminaires in line with staffing levels. Employees can use wireless light switches to adapt lighting scenes to suit their personal preferences completely independently of any wiring in the building.
