Industrial Energy Assessment: Tools and Applications

ME 50103 / 3 Cr. (3 Class)

Course synthesizes advanced energy efficiency, energy auditing, and energy management methods and practices. The fundamentals of several types of industrial audits will be analyzed with respect to the methods, tools (hand and software), and industrial applications.  Topics include energy audit process, energy bill analysis, economic analysis, measurement instrumentation, building envelop, electrical system, HVAC system, waste heat recovery, lighting, cogeneration, and other prevalent industrial systems.  Evaluation of economic, environment, politics and social policy are integral components of the course. Commercial/Institutional/Industrial scale energy audits will be conducted by student teams.

HANDBOOK OF ENERGY AUDITS by Albert Thumann, P.E., C.E.M., William J. Younger, C.E.M. and Terry Niehus, P.E., C.E.M.  8th Ed.  ISBN 0-88173-621-X And GUIDE TO ENERGY MANAGEMENT  by Barney L. Capehart, Wayne C. Turner, William J. Kennedy.  6th Ed.  ISBN 0-88173-605-8

Outcomes
  1. Synthesize the concepts, terminology, and industrial applications of various energy sources.
  2. Identify key parameters representing the energy usage and energy efficiency assessment.
  3. Demonstrate appropriate and accurate measurements using portable metrology equipment.
  4. Compute energy from different measurement systems and convert or translate the values of different forms of energy (ex. 1MMBtu of Heat versus 1MMBtu of Electricity).
  5. Justify calculations using engineering principles.
  6.  Understand the need for safety in the workplace.
  7. Work alone and in teams to investigate topics, research efficiency improvements, write reports, and make presentations on a specified energy topic.
  8. Utilize statistical methods and/or software packages to determine/predict inefficient energy use and to design/develop energy/environment/cost efficient solutions.
