“The time for delay is over, the time for denial is over.”

President Elect Barak Obama on climate change.December 9, 2008

Governor's Challenge:Governor Doyle challenged four universities in the UW system to achieve energy independence by 2012

UW-River FallsUW-Steven's PointUW-OshkoshUW-Green Bay

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

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

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

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

Energy Efficiency & Renewable Energy

Are Energy Efficiency and Renewable Energy strategies sufficient to meet emissions reduction goals? Big picture instead of

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

Photovoltaics

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

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

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)

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

Education & Outreach

Juny LeeJennifer Goyette

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

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

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

Summary

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