Maintenance Department of the airline Brussels Airlines awarded Encon the
contract to realise a relighting project in the hangar in which aeroplanes are
repaired and serviced. Because it must be possible to house several aeroplanes
simultaneously, including long-haul aircraft, this relates to a very large
building. It was an unusual project in many respects: a working height of
almost 30 metres needs installers without a fear of heights. And with passenger
aeroplanes in the immediate environment, it was also important to work very
carefully and special safety measures applied. However, the scale of the
project also strongly highlights the benefits of good relighting.
many companies were willing to take on the challenge from Brussels Airlines to
formulate and realise a relighting project for their maintenance hangar in
Zaventem. Not so surprising. It was a challenging project in many respects. But
also an example of the many benefits that redesigning a lighting installation
can have. Encon took up the challenge and was granted the contract. Since April
2012 the Brussels Airlines aeroplanes are repaired and serviced under Encon’s
new, energy-efficient lighting.
contract from Brussels Airlines stipulated the following: design and install a
new, more energy efficient lighting installation. Important condition: the
maintenance hangar must be available for continuous use during the installation
period to service the aeroplanes. Furthermore for safety reasons working above
the aeroplanes was not permitted. An additional challenge was that Brussels
Airlines could not predict when which aeroplanes would be in the hangar
beforehand. Therefore the project required flexible planning.
Consumption -70%, comfort + 70%
was granted the contract and designed an installation in which the 114 existing
light points were replaced by 484 new fittings. The light intensity on the work
floor thereby increased from an average of 200 lux to 300 lux. An increase in
lighting comfort of 70%.
the new installation has 4 times more lighting points, the quality of the light
is significantly better than in the previously existing installation: more
lighting points ensure less shadow and provide more even lighting. Furthermore
if one lighting point should fail this is hardly or not at all noticeable on
the work floor. In the old installation light failure resulted in a dark area
on the work floor.
Vanspringel, Vice President Purchasing & Facilities at Brussels Airlines,
is very satisfied with the result: “Although the new installation yields 70% more
light, the consumption has fallen spectacularly. Our new lighting installation
consumes significantly less electricity than that needed for the old
installation. This was a reduction of no less than 70%. The installation’s
annual consumption has fallen from almost 860,000 kWh approximately to 280,000
kWh. And that is a major asset for Brussels Airlines. We are, after all, striving
to decrease our energy consumption and simultaneously to reduce CO2-emissions
of our activities. In addition to the decrease in CO2-emissions of
our aeroplanes, we are also making efforts to reduce CO2-emissions
in our buildings. This relighting therefore not only saves us money on our
energy bill but also allows us to decrease CO2-emissions by no less
than 440,000 kg per year.”
significant drop in energy consumption and the improved light yield is made
possible via a well-designed combination of fittings, ballast and lights. RReflectors
were also adapted to the specific situation.
part of the saving is realised through daylight control. Because the hangar has
skylights that allow daylight in, the additional light requirement is not
always the same. In clear weather the installation therefore dims. This was not
possible with the previously existing installation which worked at full power
24/24 and 7/7.
Savings on maintenance
lights chosen are not only economical; they also have an exceptionally long
life. This not only means that savings are made on the purchase of replacement
lights. Because the lights are installed 30 metres above ground, the
replacement of the lights also entails an important cost. The old lights were
replaced each year. The new lights have an exceptional life and only need
replacing after 8 years. This provides an important financial and logistics
Environmentally friendly that pays for itself
project at Brussels Airlines is a great example of what a good relighting
project can mean: 70% more light, greater comfort due to less shadow formation,
lower energy consumption (and the CO2-emissions!) to 1/3rd
of the original consumption and decreased maintenance costs.And
this top quality installation will pay for itself in 2 years and 4 months. As
Robin Bruninx from Encon explains: “We are very happy that we had the
opportunity to realise this project.
We look back not only on a wonderful
partnership with the customer; it was also a very challenging project. This
project is a truly model project. It clearly shows all the benefits of a good
lighting installation and this combined with a good return on investment.”
