  • Don't you find that you are both arguing the same point? I suggest you go over all of How will your policies reduce energy consumption?, then Google Reduce energy costs in institutional heating and make you mind as arguing until Friday probably won't make any difference.

  • 1. Reducing your Costs and your Carbon Footprint Tom Raftery Blog: cix.ie / tomrafteryit.net Podcast: www.podleaders.com Email: tom@tomrafteryit.net
  • 2. CIX • Cork Internet eXchange - CIX • First hyper energy-efficient data centre
  • 3. Geek Porn
  • 4. Geek Porn
  • 5. Geek Porn
  • 6. Geek Porn
  • 7. Geek Porn
  • 8. Geek Porn
  • 9. CIX Vision • Energy-Efficient data centre • Why? • How?
  • 10. Why? Climate change
  • 11. Why? • DC running costs • Staffing - controllable • Connectivity - decreasing • Energy - increasing
  • 12. DC Energy requirements • Rack of equipment typically used • 1.5 kW 8 years ago • 4.5 kW 5 years ago and • 15 kW in 2006!
  • 13. Optimal DC environment
  • 14. DC Energy Flow Free Cooling
  • 15. DC Energy Flow Max Temp
  • 16. DC Energy Flow Minimise Humidification
  • 17. DC Energy Flow Water mixing
  • 18. DC Energy Flow Air mixing
  • 19. Typical DC
  • 20. Also • Low resistance, slow speed air paths • Dimplex heat exchange unit • Servers heat the CIX offices!
  • 21. Power • 10kv low impedence looped connection to the national grid • Using GE Super ECO UPS’s offering >98% efficiency
  • 22. ! Power o d Normal mode Bypass Static bypass supply o •Normal mode • The output voltage is newly generated, Rectifier Inverter independently from the input voltage Rectifie AC DC Load • Heat losses are present in rectifier and inverter r G DC AC supply Battery bank •Super Eco Mode • Load is supplied via the bypass Super Eco Mode • UPS rectifier keeps the battery charged Bypass • UPS inverter switched off supply Static bypass (no heat losses) Rectifier Inverter Transf. Rectifie AC DC Load r DC AC supply Battery bank
  • 23. End Result Standard DC CIX Chiller 33% 12% Humidifier 3% <1% CRAC 9% 4% IT Equipment 30% 80% PDU 5% 0.01% UPS 18% <2% Lighting 1% <1% Switch Gear 1% 1%
  • 24. Conclusion • Simple steps taken • Large savings and USP
