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.
