Parish church St. Josef, Holzkirchen

The sacral building is divided into the Sunday and holiday church "St. Joseph the Worker" and the chapel "The Holy Family". A flat roof in between connects both rooms and forms an anteroom.

The church room is a so-called "daylight church". The light planning should take this form into account and therefore include and support the change of the daylight. Every additional amount and dynamics of light therefore had to be positioned with great sensitivity. Despite the wonderful skylight, it was necessary to give the altar area, as the sacral centre, the appropriate weight by means of additional light sources. This was done by weighing and adjusting the amount of light entering from top to bottom. The permeability of the glass slats on the skylight was also adjusted. This means that some directed light can still pass through. When the sun is shining, the direction of the sun is definitely perceptible. Daylight plays the main role in almost all sacred buildings, which is why artificial light is only intended to accentuate the room. This resulted in a concept of reduction to two rings. One ring runs under the bench and guides the room boundaries. The other, with around 70 spotlights (iGuzzini), forms the entire skylight.

The daylight was supplemented by a lighting situation adapted to the era. Here it is restrained, reduced to the essentials. There are approx. 50 spotlights (Buschfeld) in use, which bring warm light into the room if necessary. They are small, very good in spectrum and variable in possibilities.

Almost all trades should be controlled via ISYGLT: from ventilation and audio to skylights and bells! The whole repertoire of communication possibilities was used. Both well-known binary and analog connections as well as a modern network protocol exchange were integrated. Only through our outstanding single-master BUS system is it possible to handle these transmissions quickly and fail-safe.

Of course the control of the lighting was in the foreground. For every occasion, one of the 14 lighting scenes was preset and can now be operated intuitively. The individual control of the DALI luminaires via the DALI-BUS also puts free-standing saint figures in the right light. A special feature: by combining the evaluation of outdoor brightness and visitor times, the church can be efficiently illuminated for visitors. A dynamic lighting scene in the chapel harmoniously models the room and makes the work of art shine.
