Objective Our idea was to assemble and test the Fluke Connect tools necessary to perform building tune-ups and energy inspections and diagnostics for college buildings and facilities, to ultimately decrease building energy usage by a minimum of 10%. We did not know if the buildings were shutting down at night or if they were running 24/7. We wanted to get college students and maintenance staff working together as a team to reduce campus wide energy costs on campus and across the state at other colleges and government buildings. steps and measurements your team would take. How will you document what you do? 12/7/2019 2014 FACT Training

General Summary We tested and measured large pieces of HVAC equipment within the college buildings to determine total watts consumed. We also wanted to know what buildings where shutting down at night and on weekends. We found most building on campus running 24/7. While we were doing our energy inspections, we also looked for hot spots with the thermal imager. The test points included: Amps Volts Temperature Difference across heating and cooling coils Temperatures in classrooms Thermal images of mechanical and electrical building equipment steps and measurements your team would take. How will you document what you do? 12/7/2019 2014 FACT Training

Methodology and Description of Work Done We connected to HVAC equipment including Rooftop Units (RTU’s) and large HVAC Air Handling Units (AHU’s) with VSD drives to measure Volts and Amps, so that we could calculate wattage (power). We also did an energy inspection on a campus Solar panel. We used the following Fluke tools: a3000 FC, AC Current Module a3001 FC, iFlex AC Current Module v3000 FC, AC Voltage Module t3000 FC, K-Type Température Module Ti95 Infrared Camera, with the Fluke wireless SD card Team captain, Greg Johnson, Verifying connection between Tools and smart phone. 12/7/2019 2014 FACT Training

Thermal Imaging Tis-40 We expanded on the idea of building tune-ups and energy inspections with an additional tool, the Fluke Tis-40. We used the tool to look for building energy losses and electrical hot spots. In the figure below, we found an unusual hot spot on a electrical panel that fed a local supply fan. This is a very critical tool for the project, because it can locate problems before they fail.

Energy Star Portfolio and Baseline Data The Fluke Connect meters are the tools that we used for initial testing. However, the Department of Energy “Energy Star Portfolio” is the mechanism that we used to bench mark the buildings. The person that inputs the data resides in Olympia and works for the WSU Energy Extension Office. He only inputs data 4 times a year. Thus, the before and after Portfolio results were not available for the project. Ideally, the college campus and other state buildings should train in house employees to input data monthly for more updated results and feedback.

Results Fan Kw Energy = Volts x Amps x 1.73 x PF /1000 30.57kW = 491 x 40 x 1.73 x .90 PF/1000 Typical Full Time Fan Power Costs for 1 fan @.03 = .03 x 30.57kW x 24hours x 30day = $660.31 (for 1 supply fan) Reduced by 1/3 for 16 hour/day operation = $220 saving/month Metric Goal Before After Total change kW (for 1 fan) -10% $660 $440 33% kW (for 10 fans for only 2 buildings) $6600 $4400 How do you anticipate that using the Fluke Connect app and tools will impact business? For example, what is the change before/after using Fluke Connect as demonstrated by what kind of Metric? Sample metrics include hours to complete job, cost of parts, estimated years life extension of equipment, reduction in load draw extrapolated into energy use reduction. You can reference work orders, energy usage reports and other collateral that showcase time or costs savings. kW (for 20 fans for only 4 buildings) -10% $13,200 $8800 33% 12/7/2019 2014 FACT Training

Conclusions The initial study for this project was 3 buildings and areas on the Wenatchee Valley College campus, including Wenatchi Hall, the college cafeteria and meeting rooms, and the Refrigeration building. Initial studies were only on the fans and RTU’s (Roof Top Units) of these areas. Wenatchee Hall alone uses over $10,000/month in electricity. The fans are only part of the energy consumed. The heat source is 100% electric. If the fans were shut down nights and weekends, we estimated that we could save over $4000 in electricity in Wenatchee Hall alone. We believe that if the entire campus would implement campus wide energy inspections and tune ups, the savings would exceed $50,000/year Furthermore, if the 28 other state community colleges would do the same energy inspections and testing, the state could save approximately $1,400,000 a year in energy costs (elect and gas). How do you anticipate that using the Fluke Connect app and tools will impact business? For example, what is the change before/after using Fluke Connect as demonstrated by what kind of Metric? Sample metrics include hours to complete job, cost of parts, estimated years life extension of equipment, reduction in load draw extrapolated into energy use reduction. You can reference work orders, energy usage reports and other collateral that showcase time or costs savings. 12/7/2019 2014 FACT Training

Impact & Recommendations How our team and project made a difference: We identified the need for better test tools for college maintenance staff We created a partnership between a college HVAC/Refrigeration Training program and facilities personnel We found ways to reduce over all campus energy expenses Recommendation for other to school and government agencies to apply our process: Network with college technical training programs to utilize student resources to help maintenance and facilities staff. Purchase better tools to do in-house energy monitoring to reduce energy costs. Partner with other colleges to share tools when funds are limited to help everyone reduce the costs of operating government buildings. Why do you think the wireless Fluke Connect tools and smart phone app will make a difference, compared to existing technology / methodology? AKA, why can’t your project/improvement be accomplished without Fluke Connect? Why should it be used by technicians in plant, industrial, and commercial settings. 12/7/2019 2014 FACT Training

Final Wrap-up from College Team at WVC Why do you think the wireless Fluke Connect tools and smart phone app will make a difference, compared to existing technology / methodology? AKA, why can’t your project/improvement be accomplished without Fluke Connect? Why should it be used by technicians in plant, industrial, and commercial settings. Final Comment by team Advisor-Greg Jourdan Please excuse my team of guys for their nervousness for this final filming. I am proud of them and their time and experience that they gained from this project because they made a difference. Though they represent a rural community college, they are all full time employed prior to graduation and probably will be Fluke customers for life. GJ 12/7/2019 2014 FACT Training
