Background Butte College: Functions as a selfcontained city Manages own water system Maintains own sewage treatment facility Occupies over 110 buildings & facilities on 928 acres Designated as Wildlife Refuge in 1973 BY THE NUMBERS Founded 1968 Wildlife Refuge 14,000+ Students 928 Acres 110 Buildings Own Water System Own Sewage Facility
Vision & Strategy Commitment to Sustainability Mission Statement Core Values Sustainability is one of 6 Core Values Board Policies BP #6666 Energy & Sustainability authority to continue sustainable leadership Strategic Plan Modeling Sustainability is one of 5 Initiatives
Modeling Sustainability Promotes Living Lab Through: Sustainability leadership Integration of sustainability into curriculum Carbon neutral goal by 2015 LEED for new buildings Partnerships with industry to support green economy Increase awareness Focus on Triple Bottom Line
Sustainable Land Use Clear Creek Riparian Restoration Project utilizes goats for riparian restoration. The goats consume over 90% of the non-native vegetation and weeds. Biofiltration Wetland Education Learning Laboratory (BeWELL) Project offers students in Mathematics, Engineering, and Science Achievement (MESA) an opportunity to work as interns on a real-world project by monitoring campus storm water runoff, and calculating the results necessary to biofilter the chemicals. Dining service waste is fed to over 30,000 red wiggler worms, and worm castings are then used to fertilize our growing fields.
Sustainable Land Use Agriculture Department has obtained organic certification on 26 acres where fruit, lettuce, hay, and wine grapes are grown. Wildlife Refuge offers live classroom settings that further student learning.
Recycling Meets the state standard to divert 50% of waste stream from the landfill, and recycles between 75-93% of waste each year. Operate an extensive program recycling paper, cans, bottles, scrap metal, hazardous waste, and much more. Dining Services composts 1,500 pounds of food waste each month, and recycled or recyclable materials are used for napkins, plates, food containers, and more.
Transportation Largest California Community College bus program keeps 1,500 cars off road daily Buses are biodiesel compatible, several use natural gas Preferred parking for carpool, alternative fuel, hybrid, and fuel efficient vehicles Planning with county to add bike lane to campus

Lessons Learned Set goals: Grid-Positive by 2012 Carbon Neutral by 2015 Track the changes that impact you (ex: utility rates, rebates) Know what you have to work with (budget & energy use) Don t be shy let the ESCOs know what you want Degradation of production is a reality, funding residual consumption may be necessary Implement energy saving measures first reduction is cheaper than production!
