Mitie has helped Vodafone UK save 100-gigawatt hours (GWh) of energy in three years, the equivalent of 25,000 tonnes of CO2
Mitie worked with Vodafone UK to deliver the savings as part of its energy performance contract.
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.
During the Covid-19 lockdown, all but essential technical staff were moved to home working, meaning more buildings could be hibernated.
Mitie and Vodafone will continue to assess Vodafone’s buildings to identify further energy saving opportunities.
‘100% renewable electricity by 2021’
Pradyumna Pandit, managing director, Sustainability and Energy Services, Mitie, said: “This landmark energy-saving – and staggering 25,000-tonne reduction in CO2 emissions – was made possible thanks to the collaboration between Mitie and Vodafone UK teams.
“Thank you to our energy managers, sustainability experts, and colleagues on the frontline, who have all contributed to this achievement.
“We’re proud to be helping UK businesses achieve ambitious environmental targets and look forward to continuing our work with Vodafone UK to help it meet its next energy reduction goal.”
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% 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.”
