2011 Green Fund Summary
The Green Fund provided $20,000 to enhance lighting systems in Cartwright and Whitney Centers with the condition that any enhancement have a return on investment at or under 5-years. As of November 16, 2011 various recommendations have been submitted to Student Centers management to fully use the award; to date, completed small lighting projects in Cartwright and Whitney cost $1,835.
One enhancement completed to date (11/16/2011) included replacement of 45 incandescent lamps which operated at 200-250 watts. The lamps were replaced with 65 watt self-ballasted spiral lamps. This portion of the award cost $895 with replacement labor provided by Student Centers. The project is estimated to to reduce electrical consumption by 34,000 kilowatt hours per year. This will result in an estimated savings of $2,550 per year.
The second enhancement involved removal and recycling of 32-watt 4-foot linear fluorescent lamps in portions of Cartwright and/or Whitney. Approximately 360 linear 4-foot 25 watt fluorescent lamps have been installed in select hallways, stairwells, restrooms and other common spaces. The project was completed during the summer/fall of 2011. The Green Fund award covered the $756 in material costs and Student Centers paid for labor costs to replace lamps. The project is estimated to reduce electrical consumption by 10,400 kilowatt hours per year. This will result in an estimated savings of $775 per year.
The Green Fund provided $2,100.00 to replace inefficient stage lighting for University Event Support. Stage and floor lighting is an essential service that UES offers. Our traditional equipment uses incandescent light bulbs that draw a significant amount of energy, produce intense heat and have a comparatively short lifestyle. To widen the types of services we can offer, UES applied to the Green Fund for assistance in the purchase of eight LED “Puck” lights and four DJ light fixtures. Thanks to their approval, we purchased said lights, and have been able to use them during many events, aiding student organizations and cutting our energy use in half. While providing student organizations with an eco-friendly way to celebrate, these lights have given UES employees an exciting training opportunity, showing the staff new and standard ways of programming light effects and how to professionally apply them to each event. All in all, these lights have been an exciting addition to the UES inventory and have proved their worth over and over again.
In Spring 2011, the Green Fund provided $14,331 to install hydration stations in the dorms, Cartwright Center, and Whitney. Hydration stations are the faucet like apparatuses that attach to drinking fountains. They can be used to fill up water bottles with ease. Promoting the use of reusable water bottles has a positive environmental impact because it reduces the use of disposable plastic water bottles. Most disposable plastic water bottles end up in landfills, and are significantly more expensive than refilling a reusable water bottle. This project is still underway.
The food pulper was a $2722.52 addition to the Spring 2010 Vermicomposting project. In order to aid the worms in the digesting process, the food pulper shreds up food scraps into smaller pieces to make it easier for the vermicomposting worms to digest the food. It also helps the other microorganisms to break down the food scraps.
REC LIGHTS PHASE 2
We replaced all of the fixtures and/or lamps and ballasts in the following areas within the Recreational Eagle Center at the cost of $20,200.00:
- Multipurpose room - replace 400 watt metal halide low bay lights with 6 lamp high bay fluorescent fixtures.
- Climbing wall – replace 250 watt metal halide/high pressure sodium indirect fixtures with high lumen compact fluorescent direct/indirect fixtures.
- Racquetball courts - replace 400 watt metal halide racquetball court fixtures with high lumen compact fluorescent racquetball court fixtures
- Aerobics room – replace lamp & ballasts with 25 watt lamps and ELEC PSP 1/21 0.88 BF ballasts
- Martial Arts room – replace lamp & ballasts with 25 watt lamps and ELEC PSP 1/21 0.88 BF ballasts
- Locker rooms – install 7 occupancy sensors
We have seen a 15.68% decrease in kWHr from the completion of the project March 2011 through October 2011 which is an incredible savings.
VETERANS STADIUM RECYCLE BINS
The Green Fund provided $2,340.00 to purchase permanent recycle bins for the sports complex on campus. Previous to this purchase, we had been using a more flimsy version of the recycle container that gets blown over and cannot stay out year round. Since the placement of the permanent recycle bins we have seen an increase in use of them, and allowed us to place them in more prominent locations. During major events, like football games for UW-L and high schools, concerts, and track meets, we see the use of these recycle bins go way up when placed next to a regular garbage can. Without these new bins, much of what is now recycled would go in the regular waste container.
The Green Fund provided $13,962 to remove and recycle 32-watt 4-foot linear fluorescent lamps in all residence halls, with the exception of Eagle Hall. Approximately 5,100 linear 4-foot 25 watt fluorescent lamps were installed in all hallways, stairwells, restrooms and other common spaces in all residence halls. The project was completed during the summer of 2011. Residence Life paid for the labor cost associated with this project. The project is estimated to to reduce electrical consumption by 147,600 kilowatt hours per year. This will result in an estimated savings of $11,000 per year.
The UW-L Heating Plant generates steam that is transmitted in pressurized underground pipes to campus buildings. This steam is primarily used to heat air and water. Once the steam has performed its function, it cools and condenses. The liquid condensate returns to the Heating Plant through unpressurized underground condensate return lines. To maintain functionality and optimal efficiency, UW-L’s heating system includes steam traps. A steam trap allows condensate to pass through, but maintains pressurized steam on the steam side of the trap. The warm condensate returns to the Heating Plant and is heated to create additional steam.
As with any mechanical device, a steam trap can malfunction. If the steam trap fails closed, the device that should be draining will flood and the heat transfer process will stop, and the water, air or other equipment will not be functioning properly. If the trap fails open, steam will not be completely consumed or condensed in the equipment and as steam blows through heat is lost which lowers system efficiency. The green fund award provided funds to repair and/or replace faulty steam traps in residence halls at a cost of $3,750.00.
