NATO headquarters: the AV vision enabling critical conversations

Completed in 2017, NATO’s new Brussels headquarters houses 29 embassies and brings together over 4,500 staff from allied nations, their militaries, and civil service personnel. Unlike its predecessor, the new 250,000m² building was designed to meet the highly specific workplace requirements of the military alliance. Communications technology was a central consideration from the very start.

NATO partnered with Arup in 2007 to design a next-generation audio visual (AV) solution that would enable thousands of critical conversations to take place flexibly and securely. At the same time, we were commissioned to design the information communication and technology (ICT) infrastructure that would power daily operations throughout the NATO headquarters. 

Due to the critical nature of the project, Arup worked closely together with the NATO HQ Project Office and the Belgian project management team to scope requirements and develop a 266-page specification, complete with 250 drawings, which became the brief for NATO’s Head of AV. The final design is an integrated AV system that serves NATO’s 18 room conference centre and main Council Chamber and video conference rooms; its press theatre, HD television studio, radio studios and site broadcast infrastructure.

The stringent security requirements, coupled with the scale and expectations of users, meant that we had to design for technology that wasn’t yet on the market. The result is a fully integrated system with the ability to adapt to NATO’s changing needs and advances in technology. ”

Delivering integrated, reliable communications

A military alliance demands the connection of people all over the world. Their work connects people speaking different languages, often using different technologies. The Arup-designed AV system automatically imports the agenda, attendee names and other details based on ID cards, and customises all settings to suit each delegate. To support interpreters and video streaming viewers, a single live video stream offers up to 32 languages, giving the option to choose to listen or present in any language.

Given the importance of the conversations being conducted we also designed the system’s camera placement to adjust according to attendee’s height, guaranteeing a front view, near eye contact interaction of the person talking.  


Designing for efficiency

When a system is working to support such a large building, cost and efficiency savings have to be designed in from the start. Our system can power down if no events are scheduled or a room is idle for 30 minutes, or remain on standby until 15 minutes prior to an event. The iBMS also includes a regular polling feedback system to prioritise performance efficiency. The system is also highly resilient, automatically rebooting and switching to alternative connections in the event of a system error.

Our goal was to seamlessly integrate all systems to improve the experience for users. Throughout the process we continually questioned how and why technology would be used – not just today – but for decades to come. This approach helped us create a completely new solution for NATO.  ”
