STADIUM FAÇADES / PERU NATIONAL STADIUM, LIMA, PERU MOOD LIGHTING


Sensors detect excitement levels in the stadium and instruct the facade to display one of four mood settings.


EVENT MARKERS


In addition to sensing the state of the crowd inside, the system has special displays to show who has scored, as well as schemes for non-match days.


BORING: A neutral crowd with no emotional peaks results in slow moving left to right flickering of the flames. The background remains in one fixed colour.


HOME GOAL: Fast vertical movement on each flame in red and white (like the Peruvian flag). The background also changes between white and red.


EXCITEMENT: ‘The wave’, all tubes come into play in colours between red, white, yellow and orange, in response to building excitement in the stadium.


AWAY GOAL: Flame sparkles white, blue and red as the background slowly turns white.


DISAPPOINTMENT: A sudden drop in sound following a build of excitement triggers vertical waves with colours white, cyan and blue fall in slow motion.


INDEPENDENCE DAY: Smooth change in red and white. The background and ceiling change between white and red.


CELEBRATION: Multicolour rings of different sizes explode across the facade at a different speeds.


WEEKENDS: Tubes gently change through a range of colours.


Boring, Disappointment, Excitement and Celebration. The server then prompts an e: cue lighting controller to begin displaying the appropriate pre-programmed light scheme on the façade. With just one million dollars to spend, the team needed to be creative in their choice of fixtures. The solution came from Fai Ho at Traxon, who created one-metre LED tube that displayed just two pixels, thus dramatically reducing the number of controllers required. 1,450 of the polycarbonate tubes were integrated into the curved Aluzinc grillwork of the façade to form a stylised flame pattern, with an additional 165 fixtures used to provide indirect illumination of the roof canopy. The grillwork itself is grazed with Traxon wallwashers. These, like the tubes, connect up to DMX microservers that in turn receive commands via Ethernet from the e:cue control room. The team – including the installers Concetec, lighting supplier Arquileds and associated luminaire manufacturers - had to pull out all the stops in order to meet the tight deadline, which was further squeezed by the stadiums disjointed and delayed construction phase. Traxon had to create 2,000 fixtures in


60 days and airfreight rather than ship them to Peru for a speedier delivery. Concetec had two teams working in shifts around the clock and in the final month up to 95 people could be found on site – their numbers swelled to ensure the job was completed. Claudia Paz of CAM and Arquileds’ Cesar Castro ended up moving on site so that they could manage the installation during the day and carry out vital tests after nightfall. They were joined in the last month by Christian Brink from e: cue and stage lighting specialist Luke Hall, working in a rented building across the road from the stadium. In the final five days, the entire team was in Lima, working night and day to to try and fit weeks’ worth of final system checking into the few hours that remained. Happily, their efforts paid off with the stadium fully functioning in time for the grand opening and presidential inauguration celebrations on the 26th July. The city was treated to a selection of the stadium’s new tricks and for the crew of international lighting experts, the reward was jubilant sleep - a rare case of victory for both home team and visitors. www.claudiapaz.com www.cinimodstudio.com
