We focus our energy management program on our two data centers, where we can make the most material difference. Our centers have implemented industry leading techniques to improve energy efficiency, reduce waste and offset operating emissions. The building structures provide a high level of insulation to minimize outside air infiltration and reduce solar heat gains. This lowers the thermal losses of the building which delivers a more efficient cooling profile and reduces the energy demand.
The most commonly used and cited metric for data center energy efficiency is Power Usage Effectiveness (PUE). At our data centers, we have consistently delivered a PUE that has outperformed the base building design by up to 14% by implementing multiple mitigation tactics including: optimized thermal stratification, data center air management, high efficiency HVAC chillers, speed control on cooling equipment and automated lighting control systems.
Our Basildon data center was built to stringent specifications allowing us to attain the following ISO accreditations:
We have renovated our largest offices in recent years to provide modern, well-designed and sustainable workspace for our employees. We consider the environmental impact when designing and renovating buildings, including putting in place energy efficient systems and recycling waste materials from construction.
After purchasing our Atlanta headquarters building in 2014, we initiated a major renovation that resulted in significantly enhanced energy efficiency throughout the building, including:
We completed a restoration and renovation project of the iconic New York Stock Exchange headquarters located at 11 Wall Street in 2017. Those updates included:
In London all three of our locations are ISO 50001 accredited for energy management and meet EU and UK requirements for energy use.
