The concept plan for the interior lighting of the processor hall was organized in ambient, task and accent lighting.
Ambient lighting is the base lighting throughout the entire hall, capable of supporting the least demanding activities in terms of illumination levels and uniformity ratios (circulation and orientation). The proposed strategy was to use indirect lighting mounted on 7 meter tall poles, instead of the usual downlights at ceiling height (13 to 24 meters), which resulted in decreased lighting loads.
Task lighting was implemented as a second layer, exclusively in those areas demanding specific illumination levels (check-in, baggage inspection and passport control). This strategy was preferred over the traditional “light-all” approach, since it reduced the total power loads and their associated running and maintenance costs.
A third accent layer was then employed, comprising all those tactics aimed at improving the overall space perception and enhancing the architectural composition. Vertical surfaces, artwork and a dynamic ceiling wash were some of the elements in this category.
The resulting design / plan forecasts a final lighting load of 5.82 W/m2, which is beyond the required LEED guidelines.
