Summary:Keywords: Data Center, IT infrastructure; Off-Grid photovoltaic; Self consumption PV; Energy Self-Sufficiency; Energy Management; Return of Investment; Economic analysis. 1.INTRODUCTION Based on the European Union (EU) Building Stock Observatory: 35% of the buildings are over 50 years old and 75% of the building stock is energy inefficient. (Figure 1) 2.MATERIALS AND METHODS The IT infrastructure that drives the information backbone of ICSTM is constructed on a converged network with the following Data Center Tier level 2 (according to Uptime Institute: Tier 2 - Redundant, Tier 3 - Concurrently Maintainable, Tier 4 - Fault Tolerant). (Figure 2 - top red fire suppression) In Figure 3 the primary rack hosts: - WAN interconnect (HP MSR3024 AC Router; Next Generation Firewall HP S3020F; 2x switch TOR HP 5900AF-48XG-4QSFP+; wireless controller HP 830), - Processing (16U blade servers Enclosure HP C7000, with 2 HP Blade System Proliant BL460Gen9 and 2 HP Blade System Proliant WS460Gen9), - Storage (Fast Storage array HP 3Par and one NAS server) The secondary rack hosts 4 more servers used for internal systems (BACS, Licensing, Access control, a.o); third rack hosts distribution switches for part of the network and the fourth rack hosts 4 collocated servers and a NAT storage unit. From 60 degrees fixed inclination semitransparent PV modules installed as sunshades and one MagLev with Darrieus-Savonius rotor wind turbine driven by inverter-chargers with a 48V 32kWh VRLA gel battery bank.
