We seek to drive energy efficiencies throughout our operations, both at global and local level. For instance, in Ireland, UPC took advantage of the natural climate which is optimal for using external air to cool its data centers, rather than using electricity powered air-conditioning units with compressors. The average external temperature is below 17 degrees Celsius for approximately 90% of the year. By installing two fans positioned to draw in outside air, UPC realized a 66% savings in power for cooling these locations. UPC has been using this ‘natural’ cooling method at the Sandyford site in Ireland since 2012 saving around 59,000 kWh per year. During a recent upgrade of the Churchfield data center in 2013, UPC also installed two fan units, saving a further 72,000 kWh per year.
UPC Ireland has also realized additional energy savings over the past two years through equipment upgrades and installation of high-efficiency power conversion units while removing old legacy equipment, resulting in improved power flow and reduced energy losses. Overall, UPC calculates its annual power savings from natural cooling and equipment upgrades to total more than 592,000 kWh per year, enough to power 120 family households with electricity for an entire year.
In the UK, Virgin Media started deploying smart monitoring and remote control technology in 2011 to optimize the heating, ventilation and air conditioning systems across ten key sites. As a result, Virgin Media’s energy efficiency has improved by 11% over the past two years, saving 8.6 MWh annually, enough to power more than 1,800 UK homes with electricity each year.
