To be deemed competent you must demonstrate an understanding of all aspects required of the competency. Assessment methods have been designed to measure your achievement of each competency in a flexible manner over multiple tasks.
Assessment Tasks
Students are required to complete three different types of assessment tasks
1. Workbook activities as evidence of classroom participation ( 20% weighing)
2. Design project for Residential Heating and Cooling system with minimum heat load of 150 MJ/hr ( 40% weighing)
3. Design project for Commercial heating and Cooling system for at least 4 floors ( 40% weighing).
To successfully complete this unit, a student needs to be deemed competent (CA grade) in all three assessment tasks.
Grading Criteria:
NYC - Not yet competent
CA - Competence Achieved
DNS - Did not submit assessment

Other Information
Academic Misconduct
Students are reminded that cheating, whether by fabrication, falsification of data, or plagiarism, is an offence subject to University disciplinary procedures. Plagiarism in oral or written presentations is the presentation of the work, idea or creation of another person, without appropriate referencing, as though it is one’s own. Plagiarism is not acceptable.
The use of another person’s work or ideas must be acknowledged. Failure to do so may result in charges of academic misconduct which carry a range of penalties including cancellation of results and exclusion from your course.
Students are responsible for ensuring that their work is kept in a secure place. It is also a disciplinary offence for students to allow their work to be plagiarized by another student.
Students should be aware of their rights and responsibilities regarding the use of copyright material. It is strongly recommended that students refer to the Guidelines for Students at the RMIT University Homepage.
