The building façade comprises a double-glazed unit skin, a simple
and cost-effective solution designed to control solar gains and
prevent overheating, while helping to achieve greater distribution
of daylight for an optimum indoor environment. The asymmetric
core includes the lift shafts and staircases that stand adjacent to
the inclined northern side of the building and shield the office
space from the harshest rays of the midday sun, drastically reducing
CO2 emissions by lowering demand for cooling. This reduction has
enabled the building to achieve a BREEAM ‘Excellent’ rating, the first
building to achieve such a high rating under the guidelines.
Arup worked closely with architects KPF, playing a key role in the
project, providing engineering and specialist design.
