Sweco’s building services specialists played a key role in establishing a detailed client brief which outlined Camden Council’s operational and functional requirements, as well as setting ambitious sustainability and energy efficiency targets.  It was a planning requirement that the 22,500 m² building achieved a minimum rating of BREEAM ‘Excellent’.  However, Sweco’s BREEAM Accredited Professionals were influential in persuading Camden Council, the developer and project team that a Bespoke BREEAM Outstanding would be possible.  It was an audacious objective since, at the time, there had never been an ‘Outstanding’ building that incorporated a leisure centre, library and office accommodation.
