Electricity consumption represents our main direct environmental impact and therefore deserves special attention. Approximately half of Amadeus electricity consumption comes from our Data Centre in Erding (near Munich, Germany).
In 2012, more than 400 million travel bookings and over 550 million passengers boarded were processed in the Amadeus Data Centre. Reliability and energy efficiency are critical objectives.
"The average Power Usage Effectiveness (PUE)* for the Data Centre in 2012 was 1.39"
* Power Usage Effectiveness is defined as follows: PUE = Total Facility Power / IT Equipment Power. Total Facility Power: This includes everything that supports the IT equipment load such as:
In 2012, Amadeus Data Processing Gmbh, renewed the energy efficiency certification from TÜV SÜD initially obtained in 2010. The certification process involves an in-depth review of the Data Centre operations, as well as recommendations for improvement. In addition, we continued our regular environmental audits, carried out three times a year by Bureau Veritas, in which security, safety and maintenance checks are performed.
During the year, the new energy annex building became fully operational, providing almost double capacity of power and cooling for the three firecells of the Data Centre, increased free cooling capacity and reduced cost by optimising the use of cold water provisioning from our own well.
Other measures to improve efficiency implemented or recorded in the year include the replacement of the two oldest cooling machines, serving the Operational Bridge in the Data Centre Building. On the other hand, the change from fluorescent to LEDs lamps in the three fire cells of the Data Centre (approx. 700 lights) resulted in energy savings of more than 270,000 kWh per year.
