The lack of straight lines in the various areas of the Opera House made the lighting design an exteremely difficult task. A mostly indirect scheme was decided upon to best illuminate the spaces.
steel beam of the glass curtain wall is a typical example. The beam is distributed in a triangular mesh and is totally exposed via the glass curtain wall of the main building, increasing some masculinity to the gentle architecture. Yan explains: “We hoped to illuminate the lateral face of the steel beam by lighting every triangular interior casing. Such illumi- nation became an important supplement to the interior lighting and, in particular, was an integral part of the indirect lighting of the lobby.
“At an early stage, we conceived two solu- tions: to cast light over the opposite sides from the interior angle of the triangle; or to cast light over the opposite sides from one side. In order to validate the actual effect, we made an experimental model at a ratio of 1:1 and conducted an experiment on the two solutions respectively. After having comprehensively evaluated the factors such as effect, glare control and concealment of light fittings, we eventually decided to in-

Wie Kieselsteine in einem Fluss, geglättet durch die Erosion, liegt das Guangzhou Opernhaus in perfekter Harmonie mit seinem Platz am Ufer. Sein einzigartiges Doppelfelsen-Design bereichert die Stadt durch die Öffnung zum Pearl Fluss und vereint die angrenzenden kulturellen Gebäude mit den Türmen des internation- alen Finanzzentrums in Guangzhous Neustadt Zhuji- ang. Das Auditorium des Opernhauses mit 1.800-Plät- zen verfügt über die neueste Beleuchtungstechnologie und die kleinere Mehrzweckhalle mit 400-Plätzen wurde entworfen für Performance Kunst, Opern und Konzerte in der Runde. Das Design entwickelte sich von den Konzepten einer natürlichen Landschaft und dem faszinierten Wechselspiel zwischen Architektur und Natur weiter und bindet die Prinzipien von Ero- sion, Geologie und Topographie ein. Das Guangzhou Opernhaus ist ein Beispiel einer neuen Art von Struk- tur - räumliches abgekantetes dreieckiges Gitterwerk.
crease a light slot made of steel outside the steel beam and inside the glass, and install light fittings of the same length inside the light slot to cast light towards the two steel beams on the opposite side. The curtain wall steel structure is a triangular shape, but the entire structure was extremely complicated. The triangles were not on the same plane or in parallel, the lateral face of the steel beams and the external surface (where light fittings were installed) showed a different angle with the triangle plane. This caused many problems with our analysis of the projection angle, conceal- ment and glare control of light fittings. “Hence, it was difficult to determine the reasonable shape and size of light slots as well. Through our analysis based on many electronic models and physical models, we summarised the five kinds of installation po- sitions and the projection angle of the light fittings, and identified the shape and size of light slots on this basis. In order to ensure the light fittings could be adjusted easily to
Dieser ziemlich hochtrabende Begriff bezieht sich auf die einem einschichtigen Stahlmantel ähnelnde Form, verfügt aber über ein völlig unterschiedliches struk- turelles Verhalten. Daraus ergaben sich beträchtliche Herausforderungen für die Beleuchtungsdesigner Bei- jing Light & View, insbesondere für den Chefdesigner Xiaojie An, der bei diesem dreijährigen Design und einjährigem Engineering-Prozess für das komplexe Projekt sehr eng mit Hadid zusammengearbeitet hat.

Come sassolini di un ruscello levigati dall’erosione, la Guangzhou Opera House si sposa in perfetta ar- monia con la sua località nelle vicinanze del fiume. Il suo design unico (a doppia roccia) si eleva al di sopra della città aprendosi al fiume Pearl, riunendo tra loro gli adiacenti centri culturali con le torri della finanza internazionale nella nuova città di Zhujjang. L’auditorium della Opera House con capienza di 1,800 posti ospita la più recente tecnologia d’illuminazione mentre la sala multifunzionale più piccola da 400 posti a sedere è progettata per la rappresentazione
the desired position and direction inside the light slots, we designed a special mounting bracket which can be adjusted freely to all directions.” “The time and effort spent on this project is incomparable to any other we have worked on,” states Yan. “The highs and lows have been immense but it was all worth it in the end. Every area is fantastic!”

di spettacoli d’arte, per l’opera e concerti. Il progetto si è ispirato al concetto di un paesaggio naturale e l’affascinante interazione tra architettura e natura; perseguendo altresì i principi dell’erosione, geologia e topografia. L’Opera House di Guangzhou è l’esempio di un nuovo tipo di struttura - un reticolo spaziale e triangolare di lamiera ripiegato. Il presente termine si riferisce alla sua forma similare ad un guscio d’acciaio a strato singolo, che possiede tuttavia un comportamento strutturale completamente diverso. Ciò ha rappresentato una sfida davvero ardua per i progettisti d’illuminazione Beijing Light and View, ed in modo particolare per il capo progettista Xiaojie An, che ha lavorato a stretto contatto con Hadid sia sul progetto triennale che sul progetto annuale riguar- dante l’intero processo ingegneristico.
ESPAÑOL
Como pequeñas piedras de un arroyo alisadas por la erosión, el Guangzhou Opera House se emplaza en perfecta armonía con su ubicación a orillas de río. Su diseño único realza la ciudad al abrirlo hacia el Río
Pearl, unificando los edificios culturales adyacentes con las torres financieras internacionales en la nueva ciudad Zhujiang de Guangzhou. El auditorio de 1.800 asientos del Opera House alberga la última tecnología en iluminación y el hall multifuncional más pequeño de 400 asientos se encuentra diseñado para presen- taciones de arte, opera y conciertos en disposición cir- cular. El diseño se desarrolló a partir de los conceptos de un paisaje natural y la fascinante interacción entre la arquitectura y la naturaleza; involucrándose con los principios de erosión, geología y topografía. El Guang- zhou Opera House es el ejemplo de un nuevo tipo de estructura – en- tremado espacial de platos triangulares cruzados. Este término algo grandilocuente se refiere a la forma similar de una estructura de acero de una capa única pero con un comportamiento estructural completa- mente diferente. Esto significó importantes desafíos para los diseñadores de iluminación Beijing Light & View, y en particular para el Director de Diseño, Xiao- jie An, quien trabajó muy de cerca con Hadid en el proceso de diseño durante tres años y de ingeniería durante un año para el intrincado proyecto.
