Innsbruck Airport INN (AUT)

The worldwide traffic movement presents a considerable burden for the environment – even public transport carriers in the aviation industry. Therefore, Innsbruck Airport has declared preventive environmental protection measures to be an integral part of its corporate strategy and focuses on sustainable solutions for the expansion of airport infrastructures: The apron lighting systems developed by ewo focuses completely – in a hitherto globally unique method – on energy-saving LED technology.

The 14 high mast systems with varying mounting heights (ranging from 13.5 m to 21 m) are equipped with a large number of LED light units, which are able to light up a total area of 49,000 m² in accordance with the standards of ICAO guidelines and in compliance with the EN 12464-2 standard (lighting of outdoor work places). In comparison with the originally planned project with conventional technology, this technology was able to achieve more than a 70% reduction of the energy consumption and CO2 emissions, while still producing the same technical light results and complying with all mentioned standards and safety regulations. In fact, the applied light technology works with considerably increased precision: The proportion of scattered light, which is diffused into the environment, is considerably reduced and light pollution – which is diffused into the night skies – is avoided. Only the defined area is actually illuminated and the influence on the environment is minimised.

Depending on the luminaire position and lighting requirements, up to four light panels can be accommodated in the floodlights. This reduces glare to a minimum, guarantees precise light distribution and enables large-area illumination.

In addition to the high savings potential, the LED technology from ewo also provides a number of other advantages, which are of great relevance with special regard to application on airport grounds: In addition to considerably reduced maintenance costs, the advantages particularly include fast reaction times (on/off) and the numerous possibilities of lighting control (DALI) with which the light flux can be dimmed via infinitely variable control and, thus, ideally adjusted to suit the prevailing requirements.

With the installation of this lighting system, Innsbruck Airport once more proves its dedication toward environmental protection and, with the application of LED high mast systems, becomes an international pioneer.
