  4. Reducing UWGB’s Carbon and Energy FootprintsLisa Ashenbrenner “The time for delay is over, the time for denial is over.” President Elect Barak Obama on climate change. December 9, 2008

  5. Governor Doyle challenged four universities in the UW system to achieve energy independence by 2012 UW-River Falls UW-Steven's Point UW-Oshkosh UW-Green Bay Governor's Challenge:

  6. Signed: Chancellor Bruce Shepard September 2007 Goal: Campuses across the nation become carbon neutral Reason: Prevent catastrophic climate change Role of universities as community leaders and role models American College and University Presidents Climate Commitment (ACUPCC)

  7. Designate an organizational structure to develop and implement the climate action plan Complete an emissions inventory Write a climate action plan to achieve neutrality Take two immediate steps to reduce emissions Integrate sustainability into the curriculum and other educational efforts Make the plan, inventory, and reports publicly available ACUPCC Framework

  8. Signed ACUPCC September 2007 Organizational structure: Sustainability Committee established 2007 2007 Capstone class calculated an initial carbon inventory and laid groundwork for gathering carbon calculator data First tangible action completed: U-Pass Where we are now

  9. Complete and submit an emission inventory Provide recommendations for the action plan: - Energy efficiency - Renewable resource use - Organizational structure - Educational activities Initiate educational efforts Capstone Goals

  17. Net Emissions • Offsets = 2,884 MT eCO2 • Net Emissions = 30,989 MT eCO2

  18. 2008 Detail Commuting! Natural Gas Offsets Purchased Electricity

  19. How do we compare? Divide Net Emissions by number of students Reports available at: Association for the Advancement of Sustainability in Higher Education http://www.aashe.org/resources/ghg_inventories.php

  20. Acknowledgments • UWGB staff was extremely helpful gather data and giving advice: • Facilities Management and Planning: Chris Hatfield (Director), Jason Willard • Purchasing Department: Linda Dupuis (Director), Marie Lyon Helmke, Diane Eastman • Campus Controller: Kelly Franz • Resident’s Life: Steve Gering (Assistant Director of Facilities Operations) • Shorewood Golf Course and U. Union: Rick Warpinski (Director), Nathan Rusch • Human Resources: Sheryl Van Gruensven (Director) Additionally many people helped from outside UWGB: • Russ Hardwick Green Bay Water Utility • Chambers Travel, Fox World Travel, Worldtek, and Wisconsin Air Services Thanks also to: • Professors Patricia Terry and Laurel Phoenix

  21. Potential SolutionsBenjamin NuszMolly CollardJennyHeinzen

  22. Energy Efficiency & Renewable Energy • Are Energy Efficiency and Renewable Energy strategies sufficient to meet emissions reduction goals? • Big picture instead of individual installations • Energy generation over demonstration projects • Long term implementation strategies Energy Efficiency Conservation Photovoltaics Wind Biomass Biofuels

  23. Energy Efficiency & Conservation • Central Plant • Boiler control • Chiller optimization • Boiler blowdown • Thermal storage • Variable primary flow • Academic Buildings • Windows • Variable frequency drives • Fluorescent lights • Efficient motors • Occupancy schedule • Fume hood management • Sub-metering • Demand control ventilation • Energy recovery ventilation

  24. Energy Efficiency & Conservation • Stanley Consultants 2008 Energy Audit • Used eQuest building simulations for MAC Hall and Cofrin Library • Determined a base rate of energy reductions on a per square foot basis • Used rate to estimate campus-wide implementation

  25. Photovoltaics • 2008 Non-residential Photovoltaic site assessment by Full Spectrum Solar • Modeled 5kW, 20kW and 50kW • Didn’t address the total capacity of the campus • Capstone Campus-wide site assessment • All areas were evaluated using Solar Pathfinder site assessment tool • Generated and plotted GPS coordinates • Used arcGIS to construct polygons and calculate areas • Surveyed 48 PV collector models to determine Watts/s.f. • Calculated installation density for appropriate sun angles and annual solar radiation

  26. Photovoltaics

  27. Photovoltaics • Multicrystalline collectors • 11.9 Watts/s.f. • 30 degree mounting angle • 1206 kWh/kW(rated) • Density Ratio of 0.27 • Full solar exposure If all of the available land areas were covered with PV, the system would annually produce 17,972,912 kWh or 91% of the total electrical load. At $6,700/kW the system would cost $99,849,000 Simple payback of 61.7 years

  28. Wind Power • Suggestions from 2005 site assessment: • Three sites • 10 kW – 660 kW machines • This report recommends: • Two sites • 1.5 MW or larger machines

  29. Investment & Production • UWGB has an average wind speed of 14 mph @ 265’ • The GE 1.5 MW turbine produces ~3,500,000 kWh each year at that velocity • UWGB bought 19,842,000 kWh in 07-08 @ 6.5¢/kWh • Each turbine will save ~$225,000 on annual electrical bill (avoided cost)

  30. Biomass and Biofuels • Biofuels • B20 testing underway • Future ratio increases possible • Cheapest in terms of capitol, but highest in terms of operating costs • Biomass • 2006 Capstone recommendation of wood boilers for residence halls • 20 individual boilers for 26 buildings • Future potential to install cogeneration

  31. Projections

  32. Projections - Aggressive Emissions without reductions

  33. Education & OutreachJuny LeeJennifer Goyette

  34. Addressing outreach and education Short term goals • Streamline the Sustainability Committee website to provide easy access information regarding UWGB and its efforts to be climate friendly and sustainable • Refresh links, update content, and advertise sustainablegb webpage • UWGB website tech is still working on updating it • Design informative posters for use within campus buildings and along Cofrin Memorial Arboretum trail • Educate public, students, and staff RE: UWGB sustainability initiatives • Affirm identity as an environmental university by reclaiming and using the title EcoU • Focus on broad spectrum of activities within UWGB that contribute to being an Eco campus • Explore a current issue and how it affects UWGB

  35. Poster Themes in the Arboretum Geology Implementing Sustainable Energy: UWGB potential Mahon Woods / Forest Dynamic Plot UWGB’s natural communities: Green Bay’s bay / invasive species/ succession plots / Prairie Current Issues: Wind Energy and Bats

  36. Addressing outreach and education Long term goals • Hire a permanent full-time sustainability coordinator • Interdepartmental collaboration on sustainability initiatives and increase communication between faculty members in the implementation of sustainability efforts • By collaborating with one another, faculty can extend what they learn into their lecture coursework and/or department committee meetings • Require environmental science and sustainability coursework for all students regardless of their major • Move away from traditional style of teaching • Coursework with project-based classes that allow students with hands on experience • Increase students’ awareness on sustainability issues by personalizing the experiences • If students were made aware of their “ecological address”, they would be more actively involved in the practice of environmentally sustainable living

  37. Summary • Focus on curriculum • Increase awareness of sustainability initiatives • Create an institutional culture of sustainability • Encourage change in behavior
