Mitie worked with Vodafone UK to deliver the savings as part of its Energy Performance Contract. So far, Mitie and Vodafone have audited 90 of Vodafone’s buildings, including offices, contact centres, data centres and Mobile Telephone Exchange (MTX) network sites, to assess energy usage and ensure efficiencies.
The audits checked that a building’s lighting, heating and air conditioning systems were operating at the highest energy efficiency rating. At more complex locations, such as data centres and MTX (mobile telephone exchange) network sites, where 24/7 power is essential to keep the network running, sensors providing real-time data were used to identify energy saving opportunities. For example, temperature sensors in data centres enabled the airflow to be automatically adjusted up or down remotely, ensuring the correct environment for this critical equipment in the most energy efficient way. In offices and call centres, sensors in air conditioning systems enabled ‘dynamic controls’ so the air temperature could be managed remotely and at speed dependent on weather and conditions.
Mitie had already supported Vodafone in reducing the number of buildings it opened at weekends and on bank holidays, making significant energy savings. During the Covid-19 lockdown, all but essential technical staff were moved to home working, meaning more buildings could be hibernated.
Scott Petty, Chief Technology Officer at Vodafone UK, said: “Not everything we’ve done here is revolutionary; we’ve achieved these staggering savings by doing the basics well and making energy reduction something we think about each and every day. Combined with our commitment to power our network with 100 per cent renewable electricity by 2021 – and help our customers reduce their own carbon footprints with our connectivity and Internet of Things technology – this will ensure we are helping to build a more sustainable future.”
