A GERMAN metals company has become one of the first firms in the industrial sector to pay for the replacement of its lighting with LEDs with a monthly fee in a so-called ‘lighting as a service’ contract.
Aluminium Gmbh, which supplies metal extrusions, is paying for the replacement of the ageing lighting at its factory complex outside Dortmund with a fixed monthly rate payable over six years.
In all, some eight production halls have been fitted with modern LED luminaires. The cost of design, removal of the existing luminaires, installation and annual maintenance are also built into the fee.
While this type of financing model is not uncommon in applications such as street lighting, it only currently gaining traction in the commercial, industrial and educational sectors. The concept was initially developed when LEDs were more expensive than currently and the significant energy savings would offset the capital cost of the luminaires.
The service contract – with Austrian luminaire maker Zumtobel – guarantees the company an illuminance of between 200 and 400 lux, depending on the requirements of each specific area of the production site. The high-bay lighting achieves an annual energy saving of 40 per cent compared to the previous year, while at the same time doubling the luminous intensity. The emergency lighting has also been replaced with a new central supply system and new escape-sign luminaires.
‘The modern lighting’s a real additional benefit for our staff,’ plant manager Frank Hildebrandt told Lux. ‘The high lighting level provides more comfort at work and therefore much more safety. At the same time, we benefit from great energy savings.’
