London's largest office-based solar roof panel installation is to take place in the next few weeks at developer Hammerson's final phase of the Spitalfields redevelopment in east London.

Architect Foster and Partners, working closely with engineers Arup and Hoare Lea, was keen to incorporate the solar technology into its office building at Bishop's Square. Photovoltaic roof panels, which generate electricity directly from sunlight, will be installed in the building. The installation is likely to save more than 28 tonnes of carbon dioxide emissions a year.
