Canary Wharf Contractors Ltd.
Barclays Bank Headquarters & Computer Centre
Barclays Bank was named as one of “the 30 most significant buildings constructed in the past 30 years” in 2008 by the respected ‘Building Services Journal’.
The Barclays Bank building was singled out for its robust design, which featured a high standard of sustainability and energy efficiency, rare attributes for a high technology building. It also earned the UK’s “Breeam Excellent” rating, comparable to LEED® Gold.
The tower consists of a main operations facility, data centre and trading floor with 32 floors above grade, 1,000,000+ ft2 of computer centre, trading floor and high technology office space. HH Angus provided an overall electrical and mechanical design that ensures there are no single points of failure.
Mechanical services were designed to achieve high quality practical solutions for the high cooling loads, while ensuring flexibility for subtenants and office churn. The systems boast dual risers and split plant for the majority of services in order to provide continuity of service for maintenance or in the event of failure.
Electrically, the building has an extremely resilient service provision with dual incoming electrical supplies, 8 MVA of UPS power and 12 MVA of generator power available. The design included dual 11 kV service entrance, a dual 11kV APS systems (12MW), a 2(N+1) UPS topology (8x800kW). All electrical services were provided in a dual riser and split plant format, providing continuation of service under failure or maintenance.
