The Council on Tall Buildings and Urban Habitat has announced its first 10 Year Award recipient: 30 St. Mary Axe, London, United Kingdom, popularly known as “The Gherkin.”
The 10 Year Award has been created from this year to focus the industry on performance against design intent. It recognises proven value and performance, across one or more of a wide range of criteria, over a period of at least 10 years. This new award gives an opportunity to reflect back on buildings that have been completed and operational for at least a decade, and acknowledges those projects that have performed successfully long after the ribbon-cutting ceremonies have passed.
Hilson Moran was responsible for the shell-and-core design and the fitting out of the floors occupied by Swiss Re. Extensive use was made of computational fluid dynamics and dynamic thermal modelling to inform the cladding design, mixed mode ventilation and to optimise the design of the engineering systems.
The uniquely-shaped Gherkin, completed in 2003, cleared the way for a new generation of tall buildings in London and beyond. Ten years on, its tapering form and diagonal bracing structure afford numerous benefits: programmatic flexibility, naturally ventilated internal social spaces that provide user comfort while reducing energy demand, and ample, protected public space at the ground level.
The 10 Year Award will be presented at the CTBUH 12th Annual Awards Ceremony and Dinner
in Chicago on November 7.
