Project summary
The Vauxhall Cross Transport Interchange is a striking landmark building in the heart of London. It is an excellent showcase for how photovoltaics (PV) can both enhance a structure and produce electricity in an urban environment. Vauxhall Cross is part of a major improvement programme to deliver an integrated public transport system in London, allowing easier access to, and change between bus, underground and rail. It is located on the southern boundary of the Mayor of London’s congestion charging zone. The interchange has a photovoltaic array incorporated into a canopy which provides shelter to the bus station. The canopy takes the form of a sculptural ribbon running the length of the bus station, with PV installed on the upper surface of the cantilevered ends. The interchange handles 2000 buses, 712 London Underground services, 730 rail services and 45,000 commuters daily. The PV system provides up to 30 per cent of the energy required to power the bus station area over the course of the year.

Best practice project
Installation work at Vauxhall proceeded smoothly, with Solarcentury, Transport for London, Arup Associates and Norwest Holst, the principal contractor, all working together to integrate the PV into a complex structure.

Special PV project info
PV architecture and building integrationThe PV array comprises high efficiency hybrid crystalline and thin film technology. It is installed on the upper surface of two cantilevered forks at the northern end of the canopy. The modules are mounted over stainless steel metal roof cladding fixed to the forks, which are angled at 20 degrees to the horizontal and orientated 5 degrees west of south-facing. The mounting method was designed by Arup Associates to allow flexing of the cantilevered canopy. The modules are held in a black anodised aluminium frame and mounted off the cladded roof using a ‘slotted’ bolting arrangement to the vertical rails.
PV ownershipThe project was put forward by Transport for London (TfL) as a ‘Towards an environmental action plan’ initiative, the first stage of their environmental reporting process. It was developed in partnership with Lambeth Council. The architects, Arup Associates, designed the canopy roof and oversaw its construction. Installation of the PV array was managed by Solarcentury, an accredited Energy Saving Trust Installer, using Sanyo hybrid PV modules.
