The Alan Turing Building, named after the mathematician and founder of computer science Alan Turing, is a building at the University of Manchester, in Manchester, England. It houses the School of Mathematics, the Photon Science Institute and the Jodrell Bank Centre for Astrophysics (JBCA) (part of the School of Physics and Astronomy). The building is located in the Chorlton-on-Medlock district of Manchester, on Upper Brook Street, and is adjacent to University Place and the Henry Royce Institute. While under construction, the project was known as AMPPS : Astronomy, Mathematics, Physics and Photon Science. The building was shortlisted for the Greater Manchester Building of the Year 2008 prize, which is awarded by the Greater Manchester Chamber of Commerce. The manager of the building project was awarded a silver medal in the Chartered Institute of Building "Construction Manager of the Year" awards. Architecture The £43m building was completed in July 2007, and was designed by architects Sheppard Robson. It consists of three "fingers", each of which are four storeys high. The building is of steel frame construction, with reinforced concrete stairwells, and grey zinc exterior cladding. The northern two fingers are joined by an atrium, which is spanned by a series of bridges. The southernmost finger was designed to hold low vibration laboratories, and is joined by a glazed bridge at third-floor level to the middle finger. An 'over-sailing' roof structure connects the three fingers acting as a suspension system for a photovoltaic array/solar shading using thin film technology. This photovoltaic array is designed to produce nearly 41 megawatt hours per annum, a saving of 17,000 kilograms of carbon dioxide each year. At the time of completion this was the largest photovoltaic array in North West England, and helped the architects to win an award for "Business Commitment to the Environment". One condition for planning approval was that the project included corridors for pedestrian access and visual transparency between Upper Brook Street and Oxford Road. This was to counter complaints by the residents of Brunswick, on the other side of Upper Brook Street, that previous university developments seemed to be creating a wall to them. The pedestrian walkway between the second and third finger, and the transparent atrium met these demands. This follows the line of an earlier street, when the site was a residential area, and runs from Upper Brook Street to Oxford Road and is called "Wilton Street", as it
