Sustainability
 Definition
 “meeting the needs of the present without
compromising the ability of future generations to
meet their own needs”.
 Office of Sustainability
 https://www.indiana.edu/~sustain
 Sustainability Task Force Report 2007
 7 Working Groups: Academic Initiatives, Energy,
Environmental Quality/Land Use, Resource
Use/Recycling, Transportation, Built Environment,
Food.
Sustainable Energy at IUB
Summary of Energy Working Group Recommendations
 Sustainability Task Force Recommendations:
 Set a Goal for Carbon Neutrality
 Perform an Integrated Energy Master Plan
 Develop and Implement Qualified Energy Savings
Projects
 Develop Guidance for Energy-efficient Computing
 Support Clean Coal and Renewable Energy
Technologies
Integrated Energy Master Plan
 Integrated Energy Analysis:
 Application – Process – Distribution – Conversion – Fuel
 Begin by looking at existing buildings
 Identify and eliminate losses in buildings, delivery

systems, and production facilities
Investigate renewable energy
Identify alternate fuels for central plant
Co-generation
Process optimizes entire energy system by reducing
capital costs and matching energy production with load
Qualified Energy Savings Projects
• Current over $300M backlog of deferred
renewal.
• Decreasing reliance on State R&R funds.
• Legislation allows for leveraging existing
financial vehicles.
• Targeted projects:
– Improve HVAC, lighting, and envelope performance.
– Extend building life.
– Improve & enhance academic/research space.
– Reduce operating costs.

Energy-efficient Computing
 A campus-wide guidance document will:
 Make recommendations on proper use of power-
saving features.
 Mandate shutdown of all peripherals and printers
when not in use.
 Deploy enhanced video-conferencing capability to
reduce off-site travel requirements.
Coal-Free Campus
 Institutional commitment required
 Talloires Declaration
 Currently signed by more than 400 institutional
signatories in 52 countries
 10-point plan for incorporating sustainability and
environmental literacy in teaching, research, and
outreach
 ACUPCC
 Currently signed by more than 650 university
presidents
 Includes a greenhouse gas inventory and plan to
become carbon-neutral
IUB Greenhouse Gas Inventory
Can IUB Become Carbon Neutral?
• Recommended Carbon Reduction Goals:
– 10% in 5 years, with major use of conservation,
–
–
–
–
supplemented by REC’s
20% in 10 years, using all technologies, but only
moderate REC’s
50% in 20 years, using all technologies, but only
moderate REC’s
90% in 30 years, using all technologies, but only
minor REC’s
100%, or Carbon Neutral, in 40 years.
IT IS EASY BEING GREEN!
What Does It Mean To Be GREEN?
 Definitions of GREEN
 Energy efficient
 Environmentally friendly
 Chemical-free
 Reduce waste

and 10% of all US water
 Each office worker uses 10,000 copies/year
 Each worker drives 10,000 miles/year getting to
and from work
 Set thermostat: 68o winter/76o summer
 Make double-sided copies
