062 DOHA REPORT / BURJ DOHA
withstanding temperatures of between 45-50 degree temperatures and suitable for the sea front location in the west bay of the commercial district in Doha, Qatar,” recalls Estell. “He was well versed in lighting and had specified lighting products from manufacturers all over the world. He was of the opinion that the quality associated with German engineering was needed for a project of this high profile and magnitude. He had realised that expertise in the control of light was as important as the luminaire itself. The relationship felt right from the outset.”
Each floor has a narrow expanded metal walkway between the cladding and the glass and it was here the luminaires were to be positioned, lighting an area approximately two metres wide by three metres high from a very close offset. In addition they had to be sufficiently low profile enough not to clash with the window cleaning cradle that runs on a rail and circles each floor of the building. With an average of 82 luminaire positions proposed for each of the 44 floors as well as illumination of the tall spire at the tower’s peak, a sophisticated control system was re- quired to operate all fixtures in concert. Following an initial site visit in May 2010, the Insta team were invited to return with samples to test the optics and to ensure the LED colour proposed were suitable. It also allowed them to demonstrate the proposed transition from gold to silver. As the luminaire has separate chambers, the team were able to fine-tune the beam angles to suit the space. During the mock- up, an engineer adjusted the angles and positioning of the luminaire whilst other members, located at various points around the bay, offered feedback via long-range walkie-talkies. Four of the tower’s ‘bays’ were used, spread over two floors to ensure the optimal light distribution was achieved. The tests concluded that 15 degrees in the centre chambers and 30 degrees at the
extremities provided the best effect. The fittings were angled at 5 degrees to the ver- tical and placed right up to the glazing of the internal offices. Due to the luminaires tri-layered optic the glare is minimal to oc- cupants in the offices.
The instalight 1050 fitting was adapted slightly for the project to allow for the transition from gold to silver. Inside the luminaire there are eight chambers each

Jean Nouvel工作室设计的Burj Doha(迪拜 塔)是卡塔尔首都天际线的新贵之一。覆盖 塔身连绵不断的钢格构仿传统网格屏风而 建,以此减轻当地强烈阳光的影响,夏天气 温超过50摄氏度。 Nouvel请求老朋友兼长期合作伙伴Yann
Kersale制定合适的照明方案。Kersale构思 了一个动态设计,游离于“金色”和“银 色”之间。他设想将照明置于塔身的网格 外墙,以赋予塔体珠宝般的质感。 Insta UK’s Jon Estell公司赢得青睐提供 LED灯具,既禁得起45-50度的高温,又适 合海滨地理位置。各楼层都有狭窄的金属 走道,位于外墙和玻璃之间,灯具就安装于 此,近距离照明区域大约2米宽3米高。塔高 44层,每层设计的平均灯位为82个。

Conçu par l’Atelier Jean Nouvel, le Burj Doha est parmi les plus récents ajouts à l’horizon de la capitale qatarie. La tour est recouvert d’un treillis en acier continu qui imite un écran moucharabieh traditionnel, il aide à atténuer les effets de lumière du soleil intense de la région - et des températures
estivales supérieures à 50 o C. Nouvel appel à son vieil ami et collaborateur de longue date Yann Kersalé pour développer un système d’éclairage approprié. Kersalé a conçu un design dynamique qui serait ondulation entre or et argent. Sa vision était de la lumière derrière l’habillage en treillis de la tour pour donner un bijou comme la qualité. Le britannique Jon Estell est monté à bord pour alimenter personnalisés luminaires à LED capables de résister à des températures intenses entre 45-50 degrés des températures et adaptées à la situa- tion en front de mer. Chaque étage dispose d’une passerelle métallique étroite entre le revêtement et le verre et c’est là les luminaires devaient être pla- cés, éclairer une zone d’environ 2m de large par 3 m de haut à une distance très proche. Une moyenne de 82 postes de luminaires proposés pour chacun des 44 étages.
In addition to the growing ripples of change from gold to silver, the client requested a greater level of dynamic effects. These are provided by Insta’s IP addressable control system UNIVERS.
