Data centers energy efficiency

Worldline optimizes the use of its resources to save energy: ●

initiatives [GRI 302-5]

Data center room temperatures are adjusted to the ● maximum levels compliant with the operating standards of servers for saving cooling energy. In addition, the Kyoto protocol for energy recovery has been put in place; The lighting of rooms and technical areas is optimized; ● Rooms are organized alternately in cold aisles and hot ● aisles and, for some Data Centers, even with the containment of cold aisles; Worldline’s main data centers use an infrastructure ● management (DCIM) solution for very precise, real-time monitoring of energy consumption; Monthly monitoring of CPUE for detection of consumer ● difference has been implemented. Additionally, the last Worldline data center was built in 2009 and aimed for a PUE of 1.6, which is among the top performance of the market. virtualization category The Company’s policy is to maximize server virtualization in order to reduce the number of physical servers. Indeed, from an environmental and technical point of view, virtualization yields savings by limiting the number of servers in datacenters, resulting in: Less transport of hardware; ● Less ground space used by delivered services, and thus ● reduced need to enlarge or build new datacenters; Less travel, handling and set-up cabling, reducing waste ● when unpacking equipment (packaging, pallets, plastic wrapping, cables); Less treatment of this waste (storage, waste recycling, ● disposal, etc.). Since 2009, Worldline has decided to develop server virtualization for all of its datacenters. It is one of the initiatives with the greatest impact on the Company's energy reduction and economic performance. Involving the Procurement department in replacing servers when these are upgraded and choosing the latest machinery that is more environmentally-friendly is a key factor in reducing electricity consumption. In addition, the systematic approach to move to server virtualization contributes directly to reducing waste. D.5.3.4.3 The water used in data center is mainly required for cooling servers. As water is used via a special closed-loop circuit, its consumption is not significant. Nevertheless, datacenters are equipped to monitor water consumption and track any leaks. Additionally, water spray can help to reduce peaks in power consumption by air conditioning systems. Wastemanagement through server D.5.3.4.2 Water savings category

Over the years, many actions have been implemented in Worldline data centers for energy optimization. Best practices include, for example, cooling systems that use water circuits; implementation of adiabatic cooling that avoids the sizing of the infrastructure for the hot peak days allowing to make substantial gains in energy savings. Since 2013, Worldline has managed five data centers in three different countries with a dedicated energy efficiency optimization program. As announced last year, the average power usage effectiveness (PUE) for Worldline data centers in 2017 is already 1.70 [GRI 302-5]. Further investigation is still under way to improve this average and reduce it to 1.65 within the next three years. Moreover, the latest internal report on data center power consumption showed that, overall, the various actions taken (migration, adoption of cloud solutions, virtualization, increased use of energy-efficient hardware and other optimization measures) have saved energy. Worldline applies three types of actions to data centers in favor of the environment: energy efficiency, waste management through server virtualization and water savings. These three categories are presented below with initiatives applied across all Worldline data centers. D.5.3.4.1 Worldline commits to selecting the most energy-efficient ● servers and components: All IT products such as servers and computers used in ● Data Center must meet environmental expectations for minimizing energy consumption, which implies choosing components with the best efficiency at the time of purchase; Worldline also sensitizes its purchasing department to ● choose suppliers with the highest environmental awareness; Worldline is leveraging all available technologies to attain ● energy savings.
