  1. Energy Conservation and Renewable Energy Projects Greg Wanek Senior Electrical Engineer Capital Planning and Budget UW System Board of Regents Business Finance and Audit Committee Capital Planning and Budget Committee December, 2009 - Rev. Sept. 2010

  2. UW-System Energy Report Scope Report History: 1973 Mid-East Oil Embargo Scope of Report: Large Buildings – 50M / 59M SF Buildings Included: Connected to Campus Steam Energy Inputs: KWH - Electrical Utility Bills BTU – Fuel Heat Content Unit of Measure: BTU / GSF / YR Conversion Factors: 1 KWH = 3413 BTU 10 Therms NG = 1 MMBTU

  3. Energy Use History Energy Values in BTU per GSF per Year. Electrical Use Increase: 23.5% Thermal Use Reduction: 23.3% Target: UW-Oshkosh New Academic Building Energy Model Reference Energy Usage: Typical Residence

  4. Energy Use Reduction Strategies Thermostat Settings (68 Winter - & 76 Summer) Campus Energy Management Systems Energy Benchmarking by Building Type Energy Model New Buildings Energy Saving Performance Contracts Energy Conservation Projects Campus Utility Master Planning

  5. Energy Conservation Challenges Air Conditioning Renovated and New Buildings Personal Computers Data Centers & Computer Clusters Air Conditioning Single Student Resident Halls Larger Campus Enrollments Electrical – Steam – Chilled Water Metering

  6. Declaration of Energy Independence Issued: September 27, 2006 Scope: Four Campuses to go “Off the Grid” Campuses: UW-GBY, UW-OSH, UW-RVF, UW-STP Goal: By 2012, Each Campus to Reduce CO2 Emissions by the Equivalent of Emissions due to 2005 Electrical Energy Consumption. Strategies: Energy Conservation and Renewable Energy

  7. Executive Order 145 Issued : April 14, 2006 Requirements: Reduce Energy Use per GSF by 10% by FY 2008 Reduce Energy Use per GSF by 20% by FY 2010 FY2005 Energy Use will be the Base Requires new Buildings be 30% More Efficient than Commercial Code.

  8. Executive Order 145 Energy Values in BTU per GSF per Year

  9. E. O. 145 Campus Energy Reduction FY 05 to FY 09

  10. UW – Green Bay Energy Reduction FY05 – FY09 Energy Reduction: 30% Conservation Strategies: New 86-88% Efficient Modular Steam Generator Thermostat Settings ( 68 W – 76 S) Electrical Peak Demand Chiller Plant Shutdown at Night Campus Automation System Tuning

  11. Institution Energy Use per GSF for Fiscal Year 2009

  12. UW-System Energy Benchmarking Energy Benchmarking Strategy: UW-River Falls & UW-Stout - Lowest BTU/GSF Energy Data - Electrical & Thermal GSF Building Size Data Building Type/Use Total Btu/GSF/Yr by Building Type Benchmark for Campuses to Target Benchmark Against National Data Bases

  13. Energy Conservation Challenges Air Conditioning of Single Student Residence Halls 1973 Residence Halls GSF: 8.1M 1973 Percentage of Space with AC: 0% GSF Residence Hall Spaced Razed: 0.5M GSF Constructed with AC: 2.5M GSF Space Renovated with AC: 0.5M 2012 Residence Hall GSF: 10.1M 2012 Residence Hall GSF with AC: 3.0M 2012 Percent of Space with AC: 30%

  14. Benchmark Single Student Residence Hall Energy Use All Energy Values in kBTU per GSF per Year

  15. Energy Saving Performance Contracts & Typical State Energy Projects Funded 2007-09

  16. Energy Saving Performance Contracts & Typical State Energy Projects Funded 2009-11

  17. Major Energy Project Savings Focus on Energy Incentives: $885,000 +

  18. 2009-2011 All Agency Energy Funding Energy Conservation Funding: $50M PRSB (F109) For All Agencies Requires 20 Yr. Payback Including Bond Payment 16 Yr. Simple Payback (5.25% bond & 3% Inflation) Allows Buy-down with Grants and Campus Funds
