“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 Falls

UW-Steven's Point

UW-Oshkosh

UW-Green Bay

Governor's Challenge:


American college and university presidents climate commitment acupcc

Signed to achieve energy independence by 2012: 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)


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

ACUPCC Framework


Where we are now

Signed ACUPCC September 2007 implement the climate action plan

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


Capstone goals

Energy efficiency renewable energy
Energy Efficiency & Renewable Energy implement the climate action plan

  • 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


Energy efficiency conservation
Energy Efficiency & Conservation implement the climate action plan

  • 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


Energy efficiency conservation1
Energy Efficiency & Conservation implement the climate action plan

  • 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


Photovoltaics
Photovoltaics implement the climate action plan

  • 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


Photovoltaics1
Photovoltaics implement the climate action plan


Photovoltaics2
Photovoltaics implement the climate action plan

  • 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
Wind Power implement the climate action plan

  • 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
Investment & Production implement the climate action plan

  • 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
Biomass and Biofuels implement the climate action plan

  • 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

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

Addressing outreach and education1
Addressing outreach and education implement the climate action plan

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
Summary implement the climate action plan

  • Focus on curriculum

  • Increase awareness of sustainability initiatives

  • Create an institutional culture of sustainability

  • Encourage change in behavior
