OSRAM makes best use of Bluetooth for its HubSense system.

Case Study: Office lighting for business campus – Garching near Munich, Germany. Offering small effort for great effect, HubSense makes a wireless lighting control system easier than ever before

Upgrading the lighting in an office building in Garching, near Munich, to improve energy efficiency, lighting comfort and flexibility, the client turned to OSRAM’s intelligent wireless lighting management system HubSense. Thanks to reliable Bluetooth Mesh wireless technology, the scalable retrofit solution does not require control lines and gateways, and can also be planned and pre-commissioned from anywhere using the web app. Wireless identification of the luminaires by mobile app means they can easily be assigned to individual zones on site. As a result, only the existing T5 luminaires needed to be replaced – work in the office carried on largely undisturbed.

Project description

A lighting system that is controlled entirely manually would be an outdated solution in any office today. Modern light management systems allow the lighting to be adapted to different situations and work requirements, making the day-to-day work environment as comfortable and fatigue-free as possible. At the same time, these systems help to significantly reduce operating costs.

The example of an office building on the Business Campus in Garching shows that an existing installation can easily be upgraded to an intelligent light management system.

Quick upgrade

The client opted for HubSense from OSRAM – and for good reason HubSense is a radio-based, and therefore wireless, lighting control solution designed for retrofitting in existing buildings. This meant that the existing infrastructure could not only be used without costly and time-consuming rewiring, but there was also no need for gateways or other complex IT elements.

For us as installers, the HubSense system is particularly attractive because we can use it to easily retrofit existing office luminaires,” said livebau CEO Florian Felsch, “… and a nice advantage is that we can pre-commission the system from home which saves us a lot of time on the construction site.”

Simple commissioning

Commissioning on site in Garching could then be carried out by several installers at the same time. Compared to wired DALI systems, much less commissioning time was required, thanks to pre-defined lighting control profiles,s simple luminaire localization and zone assignment via the intuitive HubSense Commissioning Tool in the mobile app. And thanks to standardized Bluetooth Mesh wireless technology, no structural work was necessary. The office staff were able to continue their work virtually undisturbed and now benefit from better, demand-led light, as employee Felizitas Korbel confirmed: “My colleagues and I were able to carry on working without distractions during the upgrade. We didn’t actually notice it that much. The new light is really pleasant to work in.”

Self-explanatory operation

Operating the HubSense light management system in Garching is just as easy as planning, installing and commissioning it. A facility manager from Sasse GmbH is excited about the options of flexibly adapting the lighting to room usage: “With the new system, I am well prepared for changes in the open-plan office. With the help of the mobile app, I can make changes myself at any time without disturbing anyone.”

Great effect

No time-consuming rewiring, no structural work, no significant downtime for office operations, but instead simple planning and fast commissioning kept investment costs in check for the upgrade in Garching. And because the new lighting system is not only comfortable but, thanks to daylight control and presence detection, also extremely energy efficient, costs will be recouped faster than for a traditional installation with manual switching. What’s more, scalability and greater flexibility leave the client well-prepared for new room uses and office concepts as business functionality evolves over time.
