1 CAMPUS ENERGY & SUSTAINABILITY ISSUES  Buildings  IU Utilities  Sustainability  Coal-free Campus  Go Green

2 Buildings  Buildings use 40% of all energy and 70% of all electricity in the US  Visit these websites for more info:    Search “annual energy review” for details on renewables, coal, electricity, gas, nuclear, & petroleum by year.  Office vs. Lab Building Energy use

4 63.5% conversion losses = heat lost to the atmosphere at the power plant site

5 Energy Consumption at IUB  Steam: billion pounds in  Condensate returned to the CHP improved from 20% to 70%  Coal: 48,758 tons burned  Natural Gas: 6,727,570 therms  Electricity: 279,612,000 KWH  Water: 717,564,000 gallons (22% in CHP)  Total Cost: $29,300,000

6 Big 10 Comparison: IU; PU; MSU; OSU; PSU; MI; U of MINN;UIUC; NU

7 Bloomington Campus Energy Usage Accumulated Cost Containment $17,200,000

8 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 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.

9 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

10 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

11 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.

12 IU Northwest Energy Savings Project Summary JCI$526,049 Siemens$303,443 ESG$843,308 Construction Costs$1,672,800 Contingency$ 66,912 Consultant Fees$ 16,000 Reimbursables$ 3,000 IU Administration1.5%$ 26,336 Cost of Capital$ 360,000 Total Project Costs Total Energy Savings $2,145,048 $ 233,992/year Total Payback 9.1 years

13 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.

14 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

15 IUB Greenhouse Gas Inventory

16 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.

18 What Does It Mean To Be GREEN?  Definitions of GREEN  Energy efficient  Environmentally friendly  Chemical-free  Reduce waste  Conserve resources  Recycle & reuse

19 What is a GREEN Home?  Eco Pulse Survey, Shelton Group ad agency  List of “Features Required for a GREEN home”  Energy Star appliances-82%  Water conserving fixtures-78%  High performance windows-71%  Renewable energy (solar)-71%  55% say green home is important  42% cannot name a green home feature  Consumers have all or nothing view of GREEN

20 What is a GREEN IU Building?  High performance envelop  VFD on all motors > 5 HP  VAV air handling system  Digital controls  Energy recovery systems  High-efficiency lighting (T8, T5, LED)  Low-flow fixtures  Low-maintenance landscaping  Located near alternative transportation

21 Green Building Construction  Install ceiling fans  Install SEER 14 or higher A/C unit  Install drywall with recycled content  Use formaldehyde-free sheathing  R-21 walls/R-50 ceiling insulation  Use low-VOC interior finishes  Use rapid regeneration materials (bamboo or cork)  Install high-reflective roof/solar-powered vents  Use linoleum vs. vinyl floor covering  Orient structure properly/generous soffit overhang  Install high-performance dbl-pane windows

22 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

23 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:  Install compact fluorescent lamps  Wash clothes in cold water in a front-loading washer  Use clothesline vs. dryer

24 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: 68 o winter/76 o summer  Make double-sided copies  Carpool, bike, or bus to work

25 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

26 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  Look for products with minimal packaging  Use re-usable cloth bags-avoid plastic  Buy bulk items  Shop at the Farmer’s Market  Use LED lights for decoration  Buy bottles vs. aluminum cans  Buy a hybrid vehicle  Changing your behavior CAN make a difference
