1 UWGB CAPSTONE 2008 Sustainability Initiatives at Eco U

2 The Project: Sustainability Initiatives at Eco U Reducing UWGB's Carbon Footprint Reducing UWGB's Stormwater Impact

3 Presentation Outline Introduction Reducing UWGBs Carbon Footprint Background Emissions Inventory Potential Solutions Education & Outreach Reducing UWGBs Stormwater Impact Background / Education & Outreach Green Roof Options Stormwater Modeling Concluding Remarks

4 Reducing UWGBs Carbon and Energy Footprints Lisa 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's Challenge: 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

6 American College and University Presidents Climate Commitment (ACUPCC) 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

7 ACUPCC Framework 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

8 Where we are now 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

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

10 ACUPCC Organizational Structure Baseline Emissions Inventory Tangible Actions - Climate Action Plan - Education & Outreach Reporting

11 Organizational Structure

12 Emissions Inventory Andrew Mckenna-Foster Angela Pierce Molly Collard

13 Inventorying Emissions Emissions of CO 2, N 2 O, and CH 4 Campus and Residence Heating Air and Bus Travel and commuting Purchase Electricity Fertilizers etc. Campus Vehicles Paper Purchasing Waste Disposal Wastewater Treatment Onsite EmissionsPurchased EnergyAll Other Emissions Forest Preservation Green Electric Purchasing Anything that reduces emissions or their impacts Scope 1Scope 2Scope 3Offests ++- Metric Tons eCO 2 (Carbon dioxide equivalent) = Carbon Footprint

14 Gathering Information To Calculator Facilities Management Residence Life Student Union. Shorewood Golf Course Purchasing Dept. Campus Controller Sustainability Committee Electricity, Fuel Paper Purchasing Solid Waste Disposal Travel Agencies Bus Companies Requested Annual Reports Everything Else

15 The Calculator Clean-Air Cool-Planet Campus Carbon Calculator version 6.

16 Total Emissions Total Emissions = 33,786 MT eCO 2 Emissions by scope:

17 Net Emissions Offsets = 2,884 MT eCO 2 Net Emissions = 30,989 MT eCO 2

18 2008 Detail Commuting! Purchased Electricity Natural Gas Offsets

19 How do we compare? Reports available at: Association for the Advancement of Sustainability in Higher Education Divide Net Emissions by number of students

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 Residents 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 Solutions Benjamin Nusz Molly Collard Jenny Heinzen

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 Didnt 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 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 & Outreach Juny Lee Jennifer 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 UWGBs natural communities: Green Bays bay / invasive species/ succession plots / Prairie Current Issues: Wind Energy and Bats



38 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

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