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

Living GREEN
Energy, Water and Waste
40% of all US energy used by buildings
40% of household water use goes down the toilet
Each of us produces 4.5 lbs./day of trash
Programmable Thermostat
Low-flow shower and toilet fixtures
Recycle
Living GREEN
Compost kitchen waste
Avoid pre-rinse before dishwasher/ run full load
Avoid garbage disposal
Use the microwave
Refrigerator is biggest energy user in kitchen
Filtered vs. bottled water
Don’t let the water run
Close the fireplace damper when not in use
Get off junk mail lists:
www.dmaconsumers.org/cgi/offmailinglist
Install compact fluorescent lamps
Wash clothes in cold water in a front-loading washer
Use clothesline vs. dryer
Working Green
Energy and waste
Commercial buildings use 18% of all US energy
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
Carpool, bike, or bus to work
Working Green
Use sleep mode for computers
Turn off peripherals at the end of the day
Recycle newspaper, office paper, and
magazines
Purchase post-consumer paper products
Turn off lights when daylight is available
Use video-conferencing when possible
Reduce packaging/shipping containers
Use ceramic mug vs. Styrofoam
Shopping Green
Waste from Use and Packaging
Every person produces 1657 lbs. trash/yr in US
1.5 billion tons/yr trash produced in the world
