Ceiling System

In addition to the function of the ceiling base layer, the lighting duct hangs the wooden panel as the ceiling material, the lighting instruments and sockets. The system makes it possible to add and change the light and each instruments freely, the flat ceiling which has no access panel is realized. The free positioning of wooden panel leads to the reduction of air-conditioning load.

In the ceiling system and lighting plan, we collaborated with Lighting Planner’s associates. The fixed raceways parallel the fa?ade every 700 mm pace, and at right angles to the line, the wooden panels of ceiling are hung from the raceways. Because the all panels are detachable freely, the flat ceiling which has no access panel is realized. By the grace of the raceways, each lighting instrument is hung and turned whenever you like, so that we can rearrange them to suit the purpose in future. In addition, it is convenient that the stock parts such as the socket and hook can be removable wherever. Because each circuit of the raceway is divided into at every zone, we can turn on the light which is needed soon, it leads to saving energy. The efficient arrangement of the lighting instruments produces the layers of wood attractively. The lighting color in office and meeting space is unified into the same color, less than 3000K. The whole building filled with the warm lighting shows the warmth of wood to the town Shinkiba at night.
