The whole world is facing a daunting array of energy & environment related challenges, which would be decisive factors in sustainable economic and industrial growth and technological innovations. There is a necessity for utilisation of energy in a rational manner without overloading the carrying capacity of ecosystem and depriving the survival of the future generation. In fact, sustainable development with minimal environmental degradation has become the motto of energy engineering. The importance of these aspects has received a new momentum in the recent past with the concerns and mechanisms originated by international level initiatives such as ISO14000 on environmental aspects in the industrial sector, and Montreal protocol and Kyoto protocol in relation to climate change. Therefore, the energy sector should not be analysed in isolation and must be dealt considering its interrelation to environment and society. For such analysis, a sound knowledge on all the related areas and associated skills are vital not only for technical aspects of energy but also for managing, advising and policy making in the sector, through well structured and planned educational framework. As such, the postgraduate programme in Energy Technology is developed with reference to synthesis of trends in sources, technologies and relevant environmental and social aspects. Detailed design aspects of energy systems and related issues are also incorporated in the programme. The knowledge and experience imparted by the programme will flow downwards to the technician level where operational & maintenance aspects of energy technology occur.

Diffuse the fundamental knowledge and state of the art of the Engineering Science involved in Energy

conservation & utilisation.

Provide an environment to foster the attainment of Research & Development targets related to the

Energy sector.

Enhance the knowledge of Engineers in contributing to national, regional 7 global energy

environmental issue and clean & efficient technologies.

The Grade Point Average (GPA) is calculated based on the summation of Grade Points earned for all

modules registered for credit (except those awarded with academic concession or withdrawn) weighted

according to number of credits, as follows.

where ni is the number of credits for the ith module and gi is the grade points earned for that module.

The GPA is rounded to the nearest second decimal place and reported on the transcript.

Eligibility for the award of PG Diploma in Energy Technology with an overall GPA not less than 2.5.

80% attendance is usually required in lectures, as specified under clause 4.1.1(a) of the By-Law.

Participation is compulsory in assignments, as specified under clause 4.1.1(b) of the By-Law

Undertaking research in a specific area is compulsory, as specified in clause 4.1.1(c) of the By-Law.

The Masters degree programme is expected to be completed in the normal duration, but may go on till

the permitted duration of study without the need of an extension as specified under section 5 of the By-

Law.

It is the responsibility of the student to obtain an extension to the permitted duration, through the Head

of Department. Such requests to extend the duration will be taken, considering the progress of the

student at the time of request.

Prior approval must be obtained in writing from the University, with the necessary documentation, for

leave of absence (as defined by the Senate). Only such leave will be considered for any official purpose,

such as considering a subsequent attempt as a first attempt.

EVALUATION AND GRADING:

Participation in the academic programme:



Only approved leave obtained on medical grounds will be normally be considered by the Senate in

extending the maximum duration of study.

The performance of each student in each module will be evaluated by continuous assessment (CA) and

end-of-semester examination (WE).

The CA component in a module normally carries a weightage of not less than 30% and not more than

60% of the total marks.

The continuous assessment of a student may be based on a specified combination of assignments

including coursework, project work, design project work, laboratory work, tutorials, field trips, field

camps, quizzes, presentations, term papers and participation in the course activities.

Each Candidate should obtain at least 40% from each of CA and WE components to obtain a pass grade

for a module.

Grade C+ or above is required to earn credit for and pass a module.

A student failing to reach 40% in one of CA or WE components receives an incomplete grade I, and is

required to repeat only the failed component/s as a repeat candidate to complete the module.

A student obtaining at least 40% in each of CA and WE components but fails to pass a module receives

an incomplete grade I, and is required to repeat either of the component as a repeat candidate to

complete the module.

A student failing to reach 40% in both CA and WE components receives an F grade, and must repeat

both components in order to upgrade the result.

The grades F or I can be improved up to a C+ grade and considered for calculating the GPA. Students

who wish to upgrade need to complete their examinations and obtain the upgraded grade before the

relevant final board of examiners after the graduation requirements are met.

The grade achieved for each module will be entered on the student’s permanent record in the registry.

The grade at the first attempt or the improved grade earned at a subsequent attempt, if any, will be

recorded.

Except when an Academic Concession has been granted, the highest grade obtainable at a repeat

attempt is the grade “C+” and it will be used for calculating Grade Point Average (GPA).

Grade N signifies an Academic Concession granted, in the event a student is unable to sit for the WE

component due to illness or other compelling reason accepted by the Senate. In such instances the

student must make an appeal, with supporting documents, to the Senate through the Director

Postgraduate Studies for an Academic concession.

Letter grades based on the Grade point system and corresponding description, as illustrated in the Table

5.1 will be used to express the performance at each module. Benchmark percentages are given for the

guidance of the examiner and may be changed upwards or downwards by the moderator in consultation

with the examiner.
