  1. Sustainable IT @ Stanford What’s IT got to do with Sustainability? • May 3, 2012 • Joyce Dickerson, Director, Sustainable IT • Stanford University

  2. Savings from Sustainable IT – to date Electricity Savings from Sustainable IT Chilled Water Savings from Sustainable IT

  3. Savings from Sustainable IT – to date Energy to cool 13,000 servers for 1 year Electricity to power 10,000 servers for 1 year

  4. The Goal: Sustainable IT = Core Operating Practice Support Research & Learning Operate Campus Sustainably Drive Infrastructure Efficiency Educate Communities Broadly Stanford Sustainable IT

  5. Intentionally Dual-report SEM /LBRE ITS/BA Sustainability & Energy Management IT Services Sustainable IT Team Sustainable IT • Facilities • Motivation, staff and money • Energy supply and building demand • Operations • Funding • IT • Equipment & rooms • Right to say ‘no’ • Sustainable IT Team • IT Leads across org (12 -->115) • Know the issues • Make it happen • Projects driven by • Payback • Incentives & rebates (internal and external) • Contribution to Sustainable Story

  6. The Goal: Sustainable IT = Core Operating Practice

  7. Building the Program • Build a Team • Build Alliances • Quantify the Problem • Build a Framework • Find a ‘Quick Win’ • Communicate • Look for Opportunities/Continuous Improvement • Deliver & Report

  8. First Project -- Quantify the Problem IT electricity use ~15% of campus total … and growing rapidly, especially research computing

  9. Build a Framework & Roadmap • Priority Projects • Desktop Computing • Power Management • Vampire Power • Climate Savers • Administrative Computing • Facility: Datacenter • Servers: Virtualization • Research Computing • Server Rooms • Research Compute Facility • All • Incentives for Action • Future Projects • Networking • Storage • Server Hardware (The “1”) • Efficient UPS • Generators • Office Equipment • A/V Equipment • Conferencing • Telecommuting

  10. Quick Win: Desktop Power Management • Central management installed on 23,000 computers • 88%: Monitors off automatically (15 mins) • 50%: Standby Enabled • >80% EPEAT • Keys to Project Success • Dept IT ‘led’ the project • Feedback: Dept Rankings • Cultural fit: Local Control Credit: iStock iPhoto; used with permission

  11. Datacenter: Energy Efficiency Retrofit • 2008: • 20,000 square foot datacenter • Raised Floor • Cooling: 13 CRAH Units • Mostly Admin Computing • Some Research • Rack Orientation: Some hot/cold • Little focus on energy use • Minimal environmental monitoring • Three temperature gauges on the wall • 2009: • Kicked Off Energy Efficiency Project • Measures Taken: • Monitoring • Temperature monitors throughout • Datacenter Dashboard • Air Flow & Temperature • VFD’s on CRAH units – running at 75% • % Outside air increased • Water chilled racks raised to 74 • Average Ambient air temp raised to 74 • Containment • Replaced aging ceiling tiles (cleanroom) • Better aligned floor and ceiling tiles, relentless blanking panels • End-aisle doors (bathtub) PUE 1.4 PUE 1.8

  12. Datacenter: Energy Efficiency Retrofit • Keys to Success: • Team = Facilities + IT Staff • Project manager from IT • Funding from facilities • Visibility to overcome concerns • Turned meter readings into meaningful charts Total Cost of the Project$336,428 Est Annual Energy Savings $175,000 Simple Payback 1.9 years Incentives from PG&E $ 36,428 Incentives from Stanford$275,000 Net Cost to Department $ 25,000 Annual kWh Savings 1,842,105 kWh

  13. Look for Opportunities: Debunk a Widely Held Belief • Tension between IT and Departments • “Don’t believe it just because they say it” • Server Room Study  Design matters • Server/Telecom Room Facility Design Guide (led by facilities) • Turnkey Retrofit kit for Server Rooms • ERP Incentives to move to SRCF “Servers Rooms are inherently inefficient and everything should move to central datacenter” Cost/kW/year=$2390 Cost/kW/year=$1171

  14. Satellite Server Rooms – Summary Table 1.65 1.99 1.54 2.63 1.38 0.2% 12% 100% 15% 2.7% 7% 14% 100% 22% 41% $19,029 $62,875 $71,995 $141,918 $261,387 $153 $125 $133 $196 $96

  15. Quantified & Shared the Cost of Running Servers

  16. Listen for Opportunities: Software Site License • Department Suggested Virtualization Site License….. • The Challenge • Pockets of virtualization deployed • Three solutions deployed • No central funding source • Inconsistent channel and pricing • Tried, and failed, in 2009 -- “it can’t be done” • The Strategy • Find out who ‘cares’ • Structure the deal – “what they expect to pay” • Pass the hat – 6 departments • The Result • The time was right • Distributed software worth over $4 million in first 4 months

  17. Impact of VMware Enterprise License Agreement Forecasts ELA • VMware ELA Stats: • $4,270,104 software to 14 departments (6 months into 3 year term) • ~400 people downloaded free VMAP software • Two types of virtual desktop services now available • VMware software now in SmartMart • The VMware portal up and running

  18. Server Virtualization Rates Vary Widely

  19. Energy Incentive Programs Stanford Energy Retrofit Program (ERP) Pays you to do Energy Efficiency Projects • 5 Years of Energy Savings • Server Room Retrofit • hot/cold aisle containment • VFDs • Controls • Server Room Relocation to SRCF • - Room converted to non-T space • UPS Replacement • - >90% energy efficient models • 3 Years of Energy Savings • Computers, Servers, Storage • 80+ Platinum Power Supplies • Desktop Virtualization • Server Virtualization • Purchase Energy Star Models • Energy efficient designs • Open to new ideas

  20. Project 6 – UPS for IT Services Project: Replace aging 500 KVA UPS with Energy Efficient 500 KVA model

  21. Project 6 – UPS for IT Services – Payback Analysis • Mitsubishi 9900B recommended • May be additional construction costs, but have $233,000 available for installation of $136,000 UPS • Price Quote from ProPower • Able to replace UPS without interrupting power to facility

  22. Rebate & Incentive Programs Sustainableit.stanford.edu Joyce Dickerson -- jdickerson@stanford.edu

  23. Lessons Learned • Be Structured, but Flexible • Dare to Challenge • Think Big • Share • Be Inclusive • Know the Culture • Document Results ($) • Talk in their Language • $$ • Carbon • Payback • kWh • Efficiency • Green House Gas

  24. Updated Sustainable IT Website Sustainableit.stanford.edu sustainableit@stanford.edu

  25. What Next? • LBRE and IT Services committed to continuing Program • Committee to determine next steps: • Matthew Ricks – IT Services • Gerry Hamilton – Facility Energy Management • Fahmida Ahmed – Office of Sustainability • Bob Burkhardt – School of Medicine • Reed Sprague – School of Engineering • Matt Riley – School of Humanities & Sciences
