COLLABORATION BETWEEN SENIOR DESIGN STUDENTS AND CAMPUS FACILITIES STAFF INCREATING A VIABLE COGENERATION DESIGN FOR THE CAMPUS WOOD-FIRED BOILERTwo Electrical Engineering and two Biological & Agricultural Engineering students initiated astudent-led project with staff at the campus steam plant to create a detailed design for a backpressure turbine, generator, and power conditioning equipment. Project learning consisted ofinterviewing electric utility staff, touring other cogeneration facilities within the region,campus-wide monitoring steam pressure to determine the minimum main steam pressure,modeling performance of different plant configurations and operating parameters usingEngineering Equation Solver, and conducting multiple design reviews with senior facilitiesstaff. Seasonal steam demand was considered in sizing the turbine and in accuratelyestimating savings in the annual campus electricity bill, amounting to $190,000. The teamreceived kudos from an architect engineering firm retained by the University and wontwo awards at the university's 2014 Design Expo. An implementation cost of $1.5 M wasestablished through deep interaction with equipment vendors and an internal rate of return of11% was determined. This easily exceeds the university minimum required for facilitiesimprovement projects. The team's solution includes instrumentation that can supportlaboratory studies in multiple STEM courses, is visually attractive in its layout within ourhistoric steam plant building, and is sustainable in its use of local wood waste. Projectoutcomes are assessed through a survey of students, faculty, and facilities staff. Successfactors included student connection with a DOE sponsored Industrial Assessment Centerprogram, professional preparation in prior course work, capstone course requirements as wellas milestones that were aligned with project needs, and a welcoming, continuousimprovement mindset displayed by steam plant personnel. The paper concludes withsuggested practices for enriching energy conservation projects done with campus facilities.
