Subject Title
Energy Auditing & Energy Eff.Large Building Design

Subject Description
This course introduces the student to the critical role that detailed energy audits play in creating more energy efficient buildings. Energy Audits are a component of Facility Condition Assessments, and include not only an audit of energy-consuming components of building systems, but also an assessment of system design, automation and controls, opportunities from recommissioning, and detailed analysis of historical energy and maintenance / operations records.
The course emphasizes a practical approach and utilizes state of the art tools to assist in quantifying savings opportunities and identifying the environmental impact of energy conservation measures. It builds on the foundations learned in studying BES701 through BES706, and BES715 and so you should have a good understanding of the basic principles of operation of the systems covered in those subjects.
In this course, you will understand the context for energy audits from both engineering and a business perspective. You will study and use common instrumentation used in auditing, as well as software that supports your analysis. You will revisit the building systems studied so far with an eye to effectively assess operation and develop conservation measures. 
You will use an industry standard energy audit analysis application (RETscreen) to quantify economic opportunities and environmental externalities as part of a major assignment.  The course includes a Lab component that includes lab exercises which must be completed.

Credit Status
One subject credit.

Learning Outcomes
Upon successful completion of this subject the student will be able to:

  1. Explain the underlying principles that define the purpose, structure, levels, methodology, scope and mandate of an energy audit.
  2. Apply selected tools and techniques to quantify and assess the historical energy performance of facilities.
  3. Examine energy rate structures as a basis for understanding past energy purchase and consumption patterns.
  4. Calculate building energy intensity; identify sources and usage of facility energy performance benchmarks.
  5. Identify typical instrumentation used in energy audits.
  6. Assess energy efficiency opportunities for building envelope, HVAC systems and the application of building control systems.
  7. Identify potential opportunities for the use of renewable energy technologies.
  8. Perform a preliminary energy management assessment as a building’s baseline.
  9. Use RETSCREEN effectively and accurately to evaluate the energy production and savings, costs, emission reductions, financial viability and risk for various types of Renewable-energy and Energy-efficient Technologies (RETs).
  10. Describe the underlying assumptions and calculation methodologies used by RETscreen in its calculations.
  11. Describe the Environmental externalities assumptions and calculations used by RETscreen in its analysis.

Academic Integrity
Seneca upholds a learning community that values academic integrity, honesty, fairness, trust, respect, responsibility and courage. These values enhance Seneca's commitment to deliver high-quality education and teaching excellence, while supporting a positive learning environment. Ensure that you are aware of Seneca's Academic Integrity Policy which can be found at: Review section 2 of the policy for details regarding approaches to supporting integrity. Section 2.3 and Appendix B of the policy describe various sanctions that can be applied, if there is suspected academic misconduct (e.g., contract cheating, cheating, falsification, impersonation or plagiarism).

Please visit the Academic Integrity website to understand and learn more about how to prepare and submit work so that it supports academic integrity, and to avoid academic misconduct.
