TfGM improved the lighting controls of the Manchester Shudehill Interchange, which includes a tram stop, bus station and car park. It installed a new automated lighting control software system and a range of lighting controls including photocells, timeclocks and passive infra-red (PiR) controls. These were installed following site energy audits, which identified the most suitable types of controls and the corresponding energy savings. The project allowed some 10% reduction of the lighting energy over a year, with peaks above 20% on specific days.
