ENTREPRISE SPIESS is a company specialising in the field of public and private construc-tion work. On the premises of ENTREPRISE SPIESS are several industrial halls, including a parts warehouse, a hall for the care and maintenance of vehicles and construction equipment, and offices. The objective was to improve the lighting situation and at the same time reduce energy consumption. The traditional lighting was no longer efficient enough and the lack of light causing shadows, was hindering technicians in their maintenance work. In the offices, the target was to increase the light levels and above all to have an automated system without manual switching and with motion detection.

In the halls, up to a height of 10 meters, the traditional lighting with high pressure dis-charge lamps or fluorescent tubes was re-placed by LED solutions. Thus 18 HIGH BAY luminaires now equip the halls and maintenance workshops. 12 waterproof DAMP PROOF luminaires were installed in the spare parts storage workshop and 18 waterproof DAMP PROOF SPECIAL luminaires were mounted in the mechanical pit.
28 FLOODLIGHT PERFORMANCE ASYM luminaires were installed in the parking lot and on the facades of the industrial halls. All these lighting renovations have improved comfort, but most importantly, safety on the works site where several thousand trucks and machinery vehicles move around every year. The lighting in the office was also optimized with LED solutions. The reception area, corridors and toilets are illuminated by 10 DOWNLIGHT COMFORT and 19 SPOT FIREPROOF FIX luminaires.
Furthermore, 55 PANEL luminaires were installed in the offices and meeting rooms and 4 SURFACE COMPACT IK10 luminaires safely guide employees through the stairwell. Sensors installed in the offices enable the automation of lighting.

The selected luminaires stand out for their high level of lighting comfort, potential energy savings and low maintenance and operating costs. Thanks to the detection sensors in the offices, the lighting automatically adjusts to presence – providing light only when it is needed - and adapts to natural light by regulating the artificial light so that there is always sufficient light intensity. The company thus saves energy and, as a bonus, does not need a manual lighting switch, which is a significant advantage, especially in times of increased hygiene requirements. In addition, the LED solutions have considerably improved the quality of light and the comfort of the employees. Maintenance costs have also been reduced, which provides a significant saving.

The complete conversion of the lighting at this site to LED solutions from LEDVANCE has significantly improved the quality of the lighting as well as the comfort and safety of the employees. Maintenance costs have also been reduced. In the offices, the lighting only needs to be switched on when required and adapts to the natural course of daylight.
