DESC9067: Mechanical Services

Semester 2, 2020 [Block mode] - Camperdown/Darlington, Sydney

This unit reviews the need for and application of Mechanical services in the built environment - in particular commercial buildings. Mechanical services are responsible for significant portion of energy and water consumption in buildings. Thus they have become important components of most modern building complexes, with a strong influence on other services and the architecture. This unit provides an introduction to these services by experienced presenters, including from the industry, for recent graduates or diplomats in mechanical engineering and an understanding of fundamental principles and practice for people from backgrounds other than mechanical engineering. Students will acquire skills in appreciation of impact of mechanical services on the environment, including recent mandatory regulations, together with estimating ventilation, cooling and heating requirements, design of simple ventilation, air conditioning and smoke hazard management systems, combined with an overview of water, refrigerant, ducted systems, with applicable equipment, energy, noise, human comfort, air quality criteria. Principles of heat transfer and fluid flow are applied to applications of mechanical ventilation, air conditioning and smoke hazard magagement, to satisfy regulations and standards, occupant and community expectations. The practical basis of the programme leads to a design assignment involving selecting equipment and systems to provide mechanical services in a building.

Assessment criteria

The University awards common result grades, set out in the Coursework Policy 2014 (Schedule 1).

As a general guide, a high distinction indicates work of an exceptional standard, a distinction a very high standard, a credit a good standard, and a pass an acceptable standard.

Result name

Mark range

Description

High distinction

85 - 100

Work of outstanding quality, demonstrating mastery of the learning outcomes assessed. The work shows significant innovation, experimentation, critical analysis, synthesis, insight, creativity, and/or exceptional skill.

Distinction

75 - 84

Work of excellent quality, demonstrating a sound grasp of the learning outcomes assessed. The work shows innovation, experimentation, critical analysis, synthesis, insight, creativity, and/or superior skill.

Credit

65 - 74

Work of good quality, demonstrating more than satisfactory achievement of the learning outcomes assessed, or work of excellent quality for a majority of the learning outcomes assessed.

Pass

50 - 64

Work demonstrating satisfactory achievement of the learning outcomes assessed.

Fail

0 - 49

Work that does not demonstrate satisfactory achievement of one or more of the learning outcomes assessed.

For more information see guide to grades.

Late submission

In accordance with University policy, these penalties apply when written work is submitted after 11:59pm on the due date:

  • Deduction of 5% of the maximum mark for each calendar day after the due date.
  • After ten calendar days late, a mark of zero will be awarded.

Academic integrity

The Current Student website  provides information on academic integrity and the resources available to all students. The University expects students and staff to act ethically and honestly and will treat all allegations of academic integrity breaches seriously.  

We use similarity detection software to detect potential instances of plagiarism or other forms of academic integrity breach. If such matches indicate evidence of plagiarism or other forms of academic integrity breaches, your teacher is required to report your work for further investigation.

You may only use artificial intelligence and writing assistance tools in assessment tasks if you are permitted to by your unit coordinator, and if you do use them, you must also acknowledge this in your work, either in a footnote or an acknowledgement section.

Studiosity is permitted for postgraduate units unless otherwise indicated by the unit coordinator. The use of this service must be acknowledged in your submission.

Simple extensions

If you encounter a problem submitting your work on time, you may be able to apply for an extension of five calendar days through a simple extension.  The application process will be different depending on the type of assessment and extensions cannot be granted for some assessment types like exams.

Special consideration

If exceptional circumstances mean you can’t complete an assessment, you need consideration for a longer period of time, or if you have essential commitments which impact your performance in an assessment, you may be eligible for special consideration or special arrangements.

Special consideration applications will not be affected by a simple extension application.

Using AI responsibly

Co-created with students, AI in Education includes lots of helpful examples of how students use generative AI tools to support their learning. It explains how generative AI works, the different tools available and how to use them responsibly and productively.

Attendance and class requirements

Please refer to the Resolutions of the University School: http://sydney.edu.au/handbooks/architecture/rules/faculty_resolutions.shtml

Study commitment

Typically, there is a minimum expectation of 1.5-2 hours of student effort per week per credit point for units of study offered over a full semester. For a 6 credit point unit, this equates to roughly 120-150 hours of student effort in total.

Required readings

Readings and various support materials will be posted to the unit’s Canvas site throughout the semester.

Learning outcomes are what students know, understand and are able to do on completion of a unit of study. They are aligned with the University's graduate qualities and are assessed as part of the curriculum.

At the completion of this unit, you should be able to:

  • LO1. appreciate the fundamentals of heat load calculations associated with sizing air conditioning systems
  • LO2. learn about the various types of air conditioning and ventilation systems
  • LO3. use techniques to work out capacities of components associated with mechanical services and work out the building space required for incorporating mechanical system components
  • LO4. understand how the air conditioning and ventilation systems are controlled to maintain indoor environmental conditions
  • LO5. differentiate between the various types of air conditioning systems with respect to energy, costs and comfort
  • LO6. appreciate the importance of building management systems and commissioning.
