1 Tuition Savings by Going Green? By: Jason Wade Va Vang Jeremy Clark Sara Lawhorn Ryan Penn Sam Ledbetter

2 Introduction Energy efficiency could lead to tuition savings for the students at NWACC?

3 Project Overview To find new ways for the college and the surrounding community to save energy by going green. To inform the community about the advantages of being more energy efficient as a community.

4 Our Solution How do we plan to do so? First, research what would go in to making the college green. Next, we would show what would be the costs to make the college green and how we could show that idea. Then, the next step would deign a model of where the green ideas would go into place on the campus. The final step, would be to show how much of an effect that the steps to go green would have added value to the college campus and the surrounding environment.

5 Expected Outcome Our research will lead to a better understanding of the savings an energy efficient campus will generate for the entire NWACC community..

7 Ideas of Saving Money While Going Green LED Lighting Water-free Urinals Reusable Energy

8 L.E.D Lights Currently, Northwest Arkansas Community College spends about $456, 737 a year on electricity. LED lighting is a great way to illustrate the benefits in energy savings, maintenance costs, and the environmental impacts by going green at NWACC. As a group, we feel the college can make vast improvements on saving money by switching to LED lighting for the classrooms. A recent study was done by Cree Inc., a manufacturer of LED lighting components, showed the total savings from using a CC vivid 2 watt LED light bulb over an incandescent 60 watt light bulb.

9 L.E.D Lights One of the key advantages of LED-based lighting is its high efficiency, as measured by its light output per unit power input. Most typical LED’s are designed to operate with no more than milli-watts of electrical power. Light Emitting Diode bulbs have been estimated to use 48 % less energy then the bulbs used in our classrooms. LED’s produce more light per watt then incandescent bulbs; which is very valuable to saving energy. LED’s are ideal for use in applications that are subject to frequent on-off cycling, unlike fluorescent lamps that burn out much quicker when cycled on and off. After 60,000 hours of use, the total cost from an incandescent 60 watt light bulb was $400.20, compared to the $46.95 of total cost from using the LED light bulb. Cree Inc’s study has shown a difference in price of 88 % over 60,000 hours of use. Though it is hard to estimate how much NWACC would save by converting to LED lights, it’s not hard to see that the savings would be crucial.

10 Costs of LED

11 Water-free Urinals Because there is no need to install water supply pipes or flush valves, the initial cost for Water-free Urinals is significantly less than flush models. Its estimated that 20 percent of all water used in a typical building is a result of flush urinals. A single water free urinal from water free Technologies can save an average of 40,000 gallons of water every year. Water-free Urinals can help reduce maintenance costs and workloads. Harsh chemical cleaners become unnecessary. Daily or as needed cleaning of the Water-free urinal is the same as standard urinals. Clean up is simple using any standard mildly acidic cleaner and a quick wipe. No rim holes or mineral deposits to worry about, just a smooth dry surface. Conventional urinals with wet surfaces can be become a breeding ground for bacterial growth and odors.

12 Water-free Urinals According to a research study evaluating Los Angeles' water supply, the amount of water that could be saved by adopting the new water- free technology could easily approach three-quarters of a billion to a billion gallons annually. 3.5 (to compare to older units) shows a savings of 9,600 to 24,500 gallons of water per cartridge. The table on the next slide gives three examples that illustrate how the Water free urinal system generates savings. All assumptions are based on conservative estimates of annual usage, water and sewer rates, and valve replacement/repair costs. Also note that special time payment and rental programs can result in zero-cost or immediate payback installations, since savings are often greater than monthly payments.

15 The rain collection in the red harvests the rain water for the irrigation and the sprinkler system at Sam’s Club. This would be good for NWACC to use for watering the plants in the green house.

21 Skills Developed Networking for life in the real world work force. Time Management - to know how to take the intuitive to complete a task Awareness of individual responsibility in a community – gain knowledge that will lead the future in making the planet a better place for us all to live. Problem solving as a team

22 Future of the Project Any EAST group could continue our project by adding pictures of the school by using Picasa (Google software) Use Revit or AutoCad software and develop an animated walkthrough of the campus.
