Background
For more than 125 years, the name Bosch has been synonymous with
future-proof technology and inventions, which have shaped the historyof the world. Sustainability and corporate responsibility are important
cornerstones of the company. Since 2003, environmental data and targets for all companies and sites have been recorded using a PC-based
environmental information system.

The lighting is controlled using OccuSwitch DALI multi-sensors. Thesensors automatically switch on and dim the light in the open-plan
office depending on occupancy and available daylight – which offers
additional energy saving as lighting is only on when and where required.

The challenge

The renovation included 240 m2 of open-plan office space, a meetingroom and the manager’s office. The old TL-D fluorescent lighting wasreplaced quickly and easily. Combined with innovative lighting control,
the use of CoreLine has achieved several positive effects: Modern LED
luminaires offer a high level of energy efficiency of 96 lm/W. As a result,the system output fell from 4,600W to 2,220W; a 52% reduction. By
ensuring the optimum control of the daylight and occupancy functions,energy savings of up to 72% can be realised. After five years, the costsavings will be more than € 15,000 or € 126 per month. What is more,
CO2 emissions will be reduced by at least 8 tonnes.

As part of the automotive technology area, Bosch’s “Gasoline Systems”
division has the same values and targets as the rest of the group. Therefore, when renovating the lighting in the Munich factories’ offices, only
a global solution would do. The new lighting had to integrate with theroom architecture, achieve significant energy and maintenance savings,
for the lowest possible investment whilst being controllable and offeringhigh comfort levels for employees.

The solution
As part of a pilot project, Bosch chose the CoreLine Recessed LEDLuminaire. Designed for low-cost office applications and renovation
projects, CoreLine Recessed offers significant savings in terms ofenergy and maintenance costs, whilst complying with office norms(DIN EN 12464-1) and creates an exceptional working environment
in terms of lighting.

Benefits

Another important aspect is employees. Thanks to the constant glarefree lighting at their workstations, employees experience better quality
lighting with higher light levels, which in turn provides better visual
comfort and aids concentration.
