Denmark’s Ramboll has been appointed to provide environmental design services for the estimated SAR1bn ($266m) Tadawul Stock Exchange building in King Abdullah Financial District (KAFD), located on the outskirts of Riyadh.

Ramboll’s role on the Tadawul tower will involve working for the project architect, Japan’s Nikken Sekkei, to design a building that will achieve a Leadership in Energy and Environmental Design (LEED) rating.

Developed by the US Green Building Council, a LEED rating is a set of standards developed to qualify environmentally sustainable design, construction and operation of buildings and neighbourhoods (MEED 7:2:10).    

For the Tadawul project, Ramboll is looking to incorporate a thermal labyrinth cooling system, which is a system of natural cooling and ventilation that guides warm air through a maze of cooled corridors before being it enters the building.

Other green design elements include mirrored ducts to introduce natural sunlight; solar shading to help reduce the cooling load; high efficiency chillers and thermal storage units. 

Ramboll also provided environmental consultancy services on Riyadh’s King Abdullah Petroleum Research and Studies Centre, which is aiming to become Saudi Arabia’s second LEED Platinum building, behind the King Abdullah University of Science and Technology.

Tadawul said further appointments to the consultancy team will be made in the coming months. It expects the project to take 43 months to complete.
