Bartons Green Initiatives 1

Energy Conservation 1992 Barton applied for its first Title III Energy grant. Additional grants were awarded in 1993, 1994, 1995, 1996, and Chapek engineering conducted energy analysis on all campus facilities for each of the grant years. The energy grants were a 50% match and had to be approved by the Department Of Energy (Federal) and the Kansas Department of Commerce. Funds could be, and were, matched with staff labor. Energy Conservation Measures (ECMs)were identified. Most ECMs had a payback of between 2-10 years. Payback generally takes the energy conservation into account, although the labor savings is not typically figured into payback. 2

ECMs that have been completed to date: Replaced all magnetic ballasts and T-12 florescent lamps with electronic ballasts and T-8 florescent lamps. Payback 3-5 years. Replaced all incandescent lamps with florescent fixtures or compact florescent lamps. Payback 6 months – 2 years. Installed motion detectors in all classrooms, restrooms, hallways, and offices. Payback 3-5 years. Installed campus-wide energy management system. Allows for optimum start and optimum stop of campus HVAC systems. Monitoring, alarms, night setback, scheduling, outside air temperature setback. Facility Management staff set up weekly scheduling of HVAC and lighting systems to maximize conservation. Payback 5-9 years. Energy Conservation (Continued) The availability of the state and federal grants started the process of looking at ECMs on the Barton campus, but the practice of analyzing the efficiency and the installation of green equipment continues today. 3

Energy Conservation (Continued) Installed Variable Frequency Drives on all motors larger than 3 horsepower. Payback 2-5 years. Installed high efficiency Swimming pool boiler. Allow central plant boilers to be shut down during summer months. Payback 2 years. Installed high efficiency forced air furnaces and air conditioning units in Student Housing, Camp Aldrich, and the 1025 Main facility. Payback 3-5 years At the 1025 Main facility, the ECM allowed for the installation of lower ceilings, insulation in ceilings, and the replacement of the windows with high efficiency double pane glass. Payback 7 years. Installation of.50 and.55 KW per ton chillers to replace the old.85 and.90 KW chillers. Payback 9 years. Replace all 1,000 watt mercury vapor parking lot lamps with 400 watt high pressure sodium lamps. Payback 3 years. Replace all 175 watt mercury vapor pole lamps (sidewalk lighting) with 150 watt high pressure sodium lamps. Payback 3 years. 4

5 Energy Conservation (Continued) Facility Management constructed the Athletic Clubhouse, Midwest Classroom addition, and the Student Union freezer addition out of eco-friendly ICF (insulated concrete forms). All three of these facilities are ultra-efficient. All new and replacement storefront glass is replaced with double pane glass and thermally broke frames. Replace swimming pool room lights, main gym lights, and Kirkman gym lights. All three facilities had 400 watt metal halide lamps and were replaced with energy efficient T-5 florescent lamps and motion detectors. Payback 8 months. Replace 1,500 watt incandescent Tennis court lights with 1,000 watt metal halide lamps. Reduced number of fixtures by half. Variable Frequency drives were installed on all three campus water wells. All new construction specifications incorporate the newest technology requiring energy efficient and compliant equipment.

In 2004, the State of Kansas initiated a program to provide assistance to governmental agencies to reduce their energy costs and make improvements to their facilities. The state provided 4 energy conservation contractors that would each run energy audits on facilities as requested. Once the audits were complete, the agency would decide which energy conservation measure (ECM) would be approved and funded. The contractor would fund the ECM and would receive monthly payments based on the savings provided by the ECM. During the audit for the campus, the following contractors provided energy audits of the campus: Johnson Controls TEC General Electric Honeywell The results of the audits indicated that all ECMs with a payback of less than 10 years had already been completed by Bartons staff. Bartons energy cost per square foot was $ This compared with similar facilities energy costs between $1.60-$3.45 per square foot. At the time of the audit, none of the 4 energy conservation contractors could provide a performance agreement that would pay off in less than 10 years. 6

Hazardous Materials & Recycling efforts All florescent lamps are Alto – green cap meaning they are environmentally safe, have reduced mercury and can be disposed of with landfill waste. Florescent lamps are extended life. The use of high intensity discharge lamps has been reduced and or eliminated when possible. Recycle & sell waste oil from auto shop (academic) and fleet vehicle shop. Oil filters are recycled with Universal recycling. Brake cleaner collected and recycled with Universal recycling. Waste paint thinner recycled with Universal recycling. Tires recycled with Becker tire. Recycle antifreeze Recycle refrigerant – Auto shop (academic), fleet vehicle shop, campus refrigeration and air conditioning units. Recycle waste metal – steel, aluminum, copper, brass, etc. collected and then taken to ACME scrap. Recycle waste paper – waste paper (office pack), shredded paper, books, magazines, & cardboard collected on campus and then delivered/or picked up by First Step Recycling Center every week. Approximately 300 lbs per week. Printing of syllabi and other coursework documentation has been reduced by providing this information online. Student bills are no longer printed and mailed. Bills are ed to students. A number of departments are now using document imaging to reduce paper & storage. Installed high efficiency front loading laundry equipment in the athletic area. 9

Hazardous Materials & Recycling efforts (continued) Chemistry department – stock of chemicals have been reduced, experiments require smaller quantities of chemicals, waste chemicals are picked up by Safety-Kleen on an annual basis (more if needed) and recycled/disposed of. Waste cooking oil from the Student Union is sold and recycled for bio-fuel. Recycled rubber is used for playground materials. Restroom stalls are manufactured from recycled milk and pop bottles. Print shop recycles silver, used film, used printing plates. Print cartridges from desktop printers are recycled. Recycled asphalt used for parking areas and service roads. Recycled concrete used for erosion control. Recycled electronic equipment (computers, televisions, phones, etc.) to ACME scrap. Recycled batteries to ACME scrap. Testing carpet squares – recycled materials used to manufacture the carpet. Switched to water based paint. Replace acid based water treatment program with electronic water treatment for campus cooling system. Low flow shower heads used in dorms. Food Service testing the trayless concept during the spring semester. Individual offices recycle aluminum cans. Installed high efficiency front loading laundry equipment in the dorms. 10

11 Other Initiatives – Instruction & Student Services Reduction of use of paper Online course shells o Electronic syllabi Handouts Tests o Archive for attendance, grades Electronic surveys, CAT forms eBooks Flyers with please recycle printed on them Instructional emphasis on value of recycling in curriculum e.g. Haz Mat tray-less cafeteria days, reduction in usage of cafeteria throw-away items
