Energy Conservation and Audit ____ Course Code: 22525, , Program Name : Electrical Engineering Program Group, Program Code : EE/EP/EU, Semester : Fifth, , Course Title : Energy Conservation and Audit, Course Code : 22525, , ‘lL. RATIONALE, , The pressure of Technological development in all sectors on the Renewable energy sources has, led to the growingthe cost of energy around the world. Efficient and judicious use of the, available energy sources would lead to the easing of such pressures and drastic decrease in the, operating costs of the organizations and industries. Thus it is necessary to save and conserve, energy to the maximum possible extent. Also essential theoretical knowledge and practical, skills about the concept of energy conservation is to be provided through different approaches,, project management and economics accepts. The process of energy audit will help to identify, the various possible avenues in which savings of energy can be effectively adopted. This, course makes the diploma holder well acquainted in the techniques of energy conservation in, , ., the fields of engineering. It also introduces him to the energy audit procedures., , “92. 5s, COMPETENCY, The: aim of this course is to help the student to attain the following industry identified, *scompetency through various teaching learning experiences:, , : .. Undertake energy conservation and energy audit., , “3. +. COURSE OUTCOMES (COs), The theory, practical experiences and relevant soft skills associated with this course are to be, taught and implemented, so that the student demonstrates the following industry oriented, COs associated with the above mentioned competency:, , Interpret energy conservation policies in India., , Implement energy conservation techniques in electrical machines., , Apply energy conservation techniques in electrical installations., , Use Co-generation and relevant tariff for reducing losses in facilities., , Carryout energy audit for electrical system., , epaege, , 4.
