2010 Green Fund Summary
$4,326.00 was used from the Green Fund for the purchase of 154 LED bulbs to replace 154 halogen light bulbs that are currently installed along track lighting in the food service areas of Cartwright Center: The Galley, Trattoria & Yan Can Cook, The Cellar, and Cyber Cafe. The new bulbs last for 50,000 hours, while the old halogen bulbs only last about 2,000 hours – thus the LEDs will last over 10 years while the current bulbs rarely last a year. This is because they use less energy for every hour they are in use, even though they emit comparable amounts of light. The LED bulbs are 3 and 5.5 watt bulbs, to replace the halogen bulbs that are 50 watt and 60 watt respectively. Therefore, LEDs are very efficient because they use less electricity to generate comparable light and they last a lot longer and save on the labor cost of replacement. Total estimated energy savings in a year is estimated to be 34,716 Kilowatt Hours (KWH), for a total electrical savings of $3,291 annually based on 90 hours of use per week, or 4680 hours per year.
The Green Fund approved an $18,944.00 project in Spring 2010 The vermicomposting project is a successful effort to reduce waste and turn it into something effective and useful. Compost is a nutrient rich natural alternative to chemical fertilizers used in conventional gardening. Vermicomposting is the process in which worms ingest food scraps, digest them and then excrete casings, the final product. The initial proposal fund helped us buy the initial group of worms and the 5 bins that are used to contain the composting process. Examples of foods that have been composted would include vegetables, non-citrus fruits, eggshells and coffee rinds. Since Thanksgiving 2011, the project has been in full swing, with both pre-consumer and post-consumer waste being composted. This project is a great way to turn something that would normally be considered waste and tossed away into something useful for our other community partners. Hillview Greenhouse currently receives the compost and Taco John's provides us with the space to keep the worm bins.
The REC Center used $80.350.00 to replace inefficient lighting in Spring 2010. They replaced 80 halide/high pressure sodium fixtures in the fieldhouse (gym area) with fluorescent fixtures. They also reduced the number of ballast input watts from 920 to 360. Additional lighting controls were added which enables lights metal to be turn on/off on a specific court and control whether 2, 4 or 6 lamps are turned on/off in each fixture.
LOW FLOW SHOWERHEADS
The Green Fund provided $9,342 to install lower flow shower heads in every shower fixture in 8 residence halls; this project affected all current halls except Reuter and Eagle. Residence Life provided labor for replacing the shower heads at no cost to the Green Fund. During the first 11 months after installation, (August 2010 - June 2011) water consumption was reduced by 26% from the prior 3-year average for the same monthly periods. This resulted in estimated savings of approximately 7.5 million gallons of water. This project also resulted in the reduction in steam consumption to heat the water and water softening salt/labor. Estimated annual savings ~$140,000.
