ADNOC New Corporate Headquarters - Abu Dhabi
Client: ADNOC
Architect: HOK - Hellmuth, Obata + Kassabaum, P.C.
Clients management team: Hill International
Clients facade and BMU consultant: Werner Sobec NY
Main Contractor: Six Construct
Structural Consultant: Halcrow Yolles
MEP Consultant: WSP - Flack + Kurtz
Facade, BMU and Media lighting contractor: Beijing Jangho Curtain Walling Co Ltd
Jangho Facade Consultant: Meinhardt Facade Technology
Jangho BMU sub-contractor: Cox Gomyl LLC
Jangho Media Lighting sub-contractor: Grandar
The building, rising over 342m, will prove to be a significant development within Abu Dhabi, not just for its height, but also for its creative design concept and its totally interactive facade lighting system allowing the South elevation to provide live art colour wash.
The main North facade makes use of double silver coated high performance glazing achieving a system U-value less than 1.93W/m2K, allowing the specified OTTV of the building to be achieved, thus meeting the demanding changes being introduced into todays environmental philosophy. This combined with a coordinated and focused management system, ensuring the building achieves LEED GOLD status.
The South facade, originally intended as a photo-voltaic design, was re-engineered as an externally ventilated twin-wall cavity. This introduced many challenges, not least being the control of temperature (ambient and material surface), and air speeds within the cavity. With the technical expertise of Meinhardt Facade (Singapore), detailed CFD studies were completed, and the design eventually achieving the overall technical demand without detracting from the aesthetic requirement.
A digital media facade is not just a series of lights placed on a building, it is a system of complicated media protocols requiring the latest technology. Technology which includes bi-direction communication to allow total system health monitoring.
Within the Southern twin wall cavity are introduced multiple LED units, with colour coordinated automated blinds to provide the back screen to match the solid cladding zones. Due to the hostile environmental conditions of the UAE, much consideration had to be given to the thermal performance of the lighting assemblies. This includes a suitable thermal resistance between the LED junction and the PCB surface, as well as the thermal resistance between the PCB surface and ambient air.
With 3840 lighting fixtures, providing over 15,360 addressable pixels, themed and sequenced light art can be broadcast across Abu Dhabi.
A multi media light management system operates by applying high frequency switching variables, defined as Pulse Width Modulation.
To control such a system requires the use of digital multiplexing for media façade applications. Digital multiplexing works with the pixel defined targets to provide selective dimming and colour mixing of the 5 colour choice of LED’s, Red, Greed, Blue, White and Amber.
With 13m spanning cable wall facades for the entrance, a complex bespoke integrated illuminated architectural clad canopy, a high specification penthouse facade design, a fully integrated complex series of BMU units covering 7 different working zones upto the helipad level glass balustrade works, Jangho are proud to be working on this landmark project.

A structure of quiet strength
Approach the ADNOC New Corporate Headquarters, and you will witness a building, standing tall and erect, screaming in silence of its own magnificence.
What HOK have achieved is little more than understated genius.
As beautifully expressed by Bill Hellmuth, President of HOK:
"Our clients in the Middle East have a wonderful, infectious energy and a commitment to building their cities.
We designed a 74-story building under construction in Abu Dhabi as the headquarters for the Abu Dhabi National Oil Company – ADNOC. Though it is very tall and will be a new UAE landmark, the building has a simple form. It creates a sense of dignity by being quiet, strong, and improbably thin and elegant. There is a lesson in that."
