Designed by a team headed by Norman Foster himself, the fascinating building certified by BREEAM (Building Research Establishment Environmental Assessment Method) reached a rating record of 98.5%, making it the world’s most sustainable office building.
The most widespread and most sustainable wood in America, red oak, has not been used in a symbolic or decorative way, but as the true aesthetic fulcrum of the interior design, in keeping with its objectives of sustainability.
Sustainable not just in an environmental sense – wood, as a renewable material, is efficient in terms of energy and rich in carbon – but also in terms of the wellbeing of people, thanks to the benefits of natural materials.
Other materials in the project include bronze and Derbyshire stone, as many as 9000 tons of it, to smoothly insert the contemporary design into the urban fabric of the City.
Oak, also chosen for its warm hues, has been used in remarkable quantity: 37,160 m2 for the floors alone.
Entering the lobby, the initial impact is sensational: the Vortex, an evocative twisting space, is formed by 1858 m2 of curved walls that intersect, all clad in red oak.
Red oak is also used in the multipurpose room, a place for meetings and presentations, and in lamellar form in the adjacent auditorium, for a total of 1350 m2.
