Changes will be made to Ealing Town Hall, Perceval House and Greenford Hall as part of an agreement between energy company E.On and Ealing Council.
The work to install technical improvements to heating and mechanical equipment at the sites will include new lighting control systems, as well as boiler optimisation and upgrades to the building management system.
New lighting controls at Perceval House will save energy through motion sensors to control lights, daylight dimming and timing controls. Lights previously left on throughout the night will automatically switch off when not in use.
Richard Scott, head of energy efficiency at E.On Connecting Energies, said: ‘We are working with councils up and down the country to help them invest in the latest energy-efficient technology; cutting energy bills and carbon emissions.
‘Through this project, Ealing Council can make substantial strides towards meeting its sustainability goals in a straightforward and financially viable way – reducing its energy costs and carbon footprint.’
Work will be carried out under an Energy Performance Contract that will see E.On guarantee energy consumption savings of 29 per cent for the council through a series of energy-efficiency improvements and investment in conservation measures.
These measures are expected to deliver savings of around £192,000 per year across the three buildings.
Ealing Council is currently inviting expressions of interest from luminaire manufacturers for its streetlighting PFI contract. The deadline for pre-qualification questionnaires is 31 July 2013.
