RE-ENGINEERING LONDON

摘要

Most people think of Bankside as an art gallery but its original function as a power station means it is still a key junction for much of the City and Southwark's power infrastructure. The substation which is part of Bankside is one of London's largest and has been refurbished with new, more compact transformers to ensure it has the capacity to supply future projects. The building has been upgraded by adding three floors and by strengthening existing slabs to take the additional loads. All this work had to be carefully phased to ensure the power supply wasn't interrupted.Unusually, the new transformers are liquid rather than air cooled due to space constraints. This had a major benefit as the waste heat has been reclaimed to preheat the hot water supply in the Tate Modern. Enough heat will be produced for the entire extension and will save £5m over the building's life.
