CAMPUS ENERGY & SUSTAINABILITY ISSUES Buildings IU Utilities Sustainability Coal-free Campus Go Green
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
63.5% conversion losses = heat lost to the atmosphere at the power plant site
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
Big 10 Comparison: IU; PU; MSU; OSU; PSU; MI; U of MINN;UIUC; NU
Bloomington Campus Energy Usage Accumulated Cost Containment $17,200,000
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.
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.
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
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.
What Does It Mean To Be GREEN? Definitions of GREEN Energy efficient Environmentally friendly Chemical-free Reduce waste Conserve resources Recycle & reuse
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
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
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
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: 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: 68 o winter/76 o 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 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
