The total electricity consumption of the top ten sites increased basically because of the growth in number of employees in these sites; but taking into consideration the entire Amadeus Group worldwide and the increased efficiency, we estimate that the total consumption went down from 80 GWh in 2010 to 78 GWh in 2011.
In 2011, several measures have been taken locally to optimise consumption. Below are examples of initiatives carried out in different sites:
For 2012 and2013 we expect to change our BMS (Building Management System) and deploy an Energy Management module with improved reporting and analysis functionality. We aim at reducing by 15% the energy required for cooling, heating and lighting. In economic terms this will be in the range of 30,000 EUR / year. In addition, we are currently piloting new air conditioning units and will monitor energy savings to decide on potential expansion and also plan to substitute traditional bulbs for LEDs in specific areas like the car parking slots.
Approximately half of the total Amadeus electricity consumption worldwide comes from Amadeus Data Centre in Erding (Germany). For this reason we focus special attention to optimise performance in this particular site.
The Amadeus Data Centre is one of the world's biggest data processing centres dedicated to the travel industry. The Data Centre operates and maintains the systems and network for all Amadeus products and provides data and transaction processing services.
The number of key billed travel transactions 1 grew from 850 million in 2010 to 948 million in 2011. The Data Centre holds a storage capacity of five petabytes. 95% of the world's scheduled network airline seats are bookable using the Amadeus Data Centre infrastructure.
Maintaining and improving energy efficiency of the Data Centre is an important Amadeus objective both from the environmental and economic point of view.
The official general energy efficiency policy of Amadeus Data Processing, introduced in 2009, focuses on the following aspects:
