Description

Energy Efficiency Analysis is a highly-demanded and valued skill nowadays and the goal of this course is to provide you with necessary knowledge and confidence to perform this analysis on your own. You will be equipped with skills to perform needed calculations and to use available web tools to help you with your analysis.

In this course, you will learn how to identify electrical energy savings possibilities in an industrial and commercial facilities, in which ways the efficiency can be improved, how to select the right equipment for efficiency improvement and how to calculate the electricity bill savings. Finally, you will be able to determine the pay-off time for the investment you have proposed.

The focus of the energy audit of electrical system is on electric motors and electric motor driven systems such as hydraulic (pump) and ventilation (fan) systems. These systems have been chosen for the analysis due to their dominant influence on overall electricity consumption and biggest energy saving potential.

You will learn to make investment proposals and to calculate pay-off time of high-efficiency motors and frequency converters in pump and fan applications. Special attention is given to pump and fan application due to their wide presence and big electricity saving potential. This course contains tutorial on free online tool that can be used in practice to perform calculation and to generate report on electricity savings in pump and fan applications.

By the end of this course, you will be equipped with practical skills needed to evaluate and improve energy efficiency of Electric Motors and Drive Systems, perform needed calculations of saved kWh, propose investment into improving energy efficiency, as well as to provide the information about investment pay-off time.


Target audience for this course are Engineers, Technicians and other Professionals in the fields of Electrical Engineering, Energy Management and Industrial Operations, as well as anyone else interested in this subject.
