How can we get more information with respect to ventilation layout and not just materials used ?

Hi Fotios, during my research I didn't find anything about the ventilation system and even after a check on Herzog & de Meuron's website, there is nothing about ventilation. It is a good read though with lots of great information about the project: https://www.herzogdemeuron.com/index/projects/complete-works/226-250/230-elbphilharmonie-hamburg.html
