A Delmatic lighting management system is enabling Vestas Blades UK to reduce lighting energy consumption and cost of ownership at its wind turbine blade manufacturing facility on the Isle of Wight. The system is also used for testing and monitoring of emergency lighting.

Vestas Blades is the world’s largest supplier of blades for wind turbines and also places great emphasis on its own environmental performance. For example, the company has made significant changes to its design and manufacturing process to reduce the use and impact of resources wherever possible.

In parallel with these initiatives the company wanted to ensure its Isle of Wight building performed efficiently and controlling the lighting was a key element of this strategy. Products used include Metro Multi-Way hard-wired modules and Metro 10-way plug-in modules.

The system is linked to the predominantly high frequency, dimmable fluorescent lighting through DALI buswire modules, enabling each luminaire to be addressed individually. The control strategy delivers a high level of flexibility, controlling each zone to minimise energy consumption in relation to activities in the spaces. This is achieved through a combination of daylight linking, time control, presence and absence detection.

In addition to saving energy, the system helps to extend lamp life so that re-lamping cycles are extended and maintenance costs are reduced – this overhead being further reduced by the automatic testing and monitoring of emergency lighting. The environmental impact of lamp disposal is also minimised as lamps last longer and fewer will be used through the life of the building.
