The graph below illustrates energy efficiency improvements. Despite the significant increase in business activity, reflected in the key billed transactions growth, the energy required grew at a much slower pace, resulting in a 8% increased efficiency in terms of energy required per transaction, and despite the fact that in 2010 the energy efficiency per transaction was also increased by 14% compared to 2009, as reported in 2010 Amadeus Corporate Responsibility Report.
Amadeus Data Centre was awarded the "Energy-efficient Enterprise" certification by international organization TÜV SÜD 1 in March 2010. The certificate was granted following an energy audit of Amadeus Data Centre facilities.
The certification was the result of a year-long process, during which time Amadeus conducted a full review of its data centre's energy efficiency. Of particular focus were the power supply, cooling and climate control processes and IT equipment used, as well as the facility's procurement, installation and de-installation processes and procedures.
Following the audit, TÜV SÜD worked together with Amadeus's facility management, storage management and capacity planning contacts to develop a plan for implementing energy saving measures in order to gain certification as an energy-efficient enterprise.
As a result of certification, internal guidelines now exist that assess all data centre activities from a sustainability perspective, whilst Amadeus is making additional efforts to continue operating its data centre in a resource-efficient manner in order to achieve renewed certification in 2012. In parallel, Amadeus is maintaining the highest possible technical service levels for all customers at all times.
Hardware at the Data Centre is positioned in a strict hot and cold aisle concept, improving cooling capacity and enhancing energy efficiency. Additionally, during 2010, water registers of the sensitive cooler systems were replaced with new registers providing a greater surface to extract heat from the air flow in our computer rooms. This allows the sensitive coolers to run on a lower fan speed, which in turn means reduced electricity consumption.
In December 2011 all lights in the fire cells where changed to LEDs. Expected savings will be in the range of 250,000 kWh and more than 27,000 EUR per year.
