Capital Market Authority (CMA) Tower

Riyadh, Saudi Arabia


Jangho Curtain Wall Co.


The Capital Market Authority (CMA) office tower is located in the King Abdullah Financial District in Riyadh, Saudi Arabia. The Tower is the tallest of the five surrounding structures that make up the financial plaza. Once completed this pillar of architectural beauty will boast 300,000 square feet over 79 storeys and will be one of the tallest structures in the world. The podium structure at the base integrates public circulation (via the district’s ‘sky-bridge’ system) with the private amenity spaces which include the CMA dining facilities and a two storey state-of-the-art auditorium, all within a breathtaking contemporary design. It will also be used as the central building regulating the Saudi Stock Exchange, as well as for enforcing rules and settling disputes within the capital markets.

Novus was retained by Jangho Curtain Wall Co. to provide consultation on aeroacoustics (wind-induced noise). This included wind tunnel testing of components of the high-performance solar shading system and associated access catwalk to assess the potential for noise caused by interaction of the exterior cladding with site winds. Testing of a full-scale section of the catwalk and scale model of the solar shades was conducted over a four-day period at the Boundary Layer Wind Tunnel in London, Ontario.
