What you’ll learn
- How to apply the first law of thermodynamics to determine system or process efficiency.
- The characteristics of water and air – essential knowledge for energy auditors.
- The 4 mechanisms of heat transfer.
- How to calculate heat energy, and electrical energy usage.
- Energy characteristics of fuel – and why you need to be careful with heating values.
- How to avoid the easy to make mistake even the smartest auditors make.
One of the great things about energy efficiency as a career is the challenge of mastering a broad area of knowledge, so that you can provide good advice. The sort of advice that needs to be provided in an energy audit.
An understanding of the theory of energy fundamentals underpins a lot of this knowledge. If you don’t understand this theory, you’ll probably find it hard to identify those large savings opportunities that good auditors seem to be able to pull out of a hat. And without a good grasp of energy fundamentals you’ll be more likely to fall for dubious product suppliers using pseudo-science to promote products that supposedly deliver massive savings.
In this course you’ll learn out to apply the first law of thermodynamic and how to determine the overall efficiency of a system or process. The course then moves on to cover the fundamentals of electricity and heat transfer. It looks as the properties of air and water. Understanding these properties is essential if you want to be able to understand HVAC&R system. With the global demand for cooling, showing very strong growth, as an energy auditor you need to have a good grasp of HVAC&R, and the fundamentals underpinning it.
Finally the course looks at an easy to make mistake associated with energy calculations, and how to avoid it.
The assessments in this course really test your knowledge of the subject matter presented (hint – you’ll be doing calculations), and if you pass the assessments you’ll get a well-earned Certificate of Knowledge.
Who this course is for
This course is for those undertaking energy audits, anywhere. Metric / System Internationale (SI), units, are used. It is particularly aimed at those who may be coming into energy auditing from a fairly narrow focus, and for those who don’t have broad understanding of the fundamentals of electrical and mechanical engineering as related to energy.
This course is for you if any of the following apply:
Why and how this course has been developed
Energy auditors with an understanding of energy fundamentals can figure out how to save more energy than those who don’t have this understanding. And they’ll be able to scrutinize potential solutions with a critical eye.
Clean energy – and by extension energy efficiency – is emotionally attractive to many people. Look at the sky-high valuations of many green technology companies. This emotional attraction, which with energy efficiency also has financial attraction – “look at how much money you can save!” And this can mean that wishful thinking replaces science. An energy user or advisor, seeing a new product that has been promoted by a very enthusiastic salesperson, and which will “slash greenhouse gas emissions” may get caught up in hype for a technology which doesn’t really work. If you understand energy fundamentals, you should be able to see through this.
What this course isn’t
This course is not a deep-dive into energy fundamentals. It introduces you to fundamental principles. Links to further resources are provided. But it doesn’t provide a comprehensive coverage. Rather the focus is on opening up a way of thinking. Think of it as a little like a driver’s license for undertaking comprehensive energy audits. Once you know these fundamentals you should be able to tackle any site, and have a framework of thinking about energy. But, just as any ace racing car driver will tell you, there is also a lot more deep knowledge underpinning the fundamentals if you want to become an elite auditor.
Part of series of courses
This course is the third part of a series on energy audits, which trains, and assesses for competence, in the ability to delivery an Investment Grade Audit.
Part 1: Commissioning and Managing an Energy Audit, is primarily aimed at energy users, but every energy auditor should also undertake this course to be able to see the audit from the other side of the fence, and thus improve your ability to effectively engage with energy users.
Part 2: Process of Undertaking a Successful Audit, presents a process, that when followed, will help you undertake successful audits. This process can be applied to deliver an Investment Grade Audit (IGA) or Detailed Feasibility Study (DFS).
If you have not already undertaken these courses it is a recommended pre-requisite.
Part 4: Tools for Energy Auditors. This course introduces energy auditors to tools, both essential and nice-to-have, for undertaking energy audits.
Section 2 – Energy using technologies and energy savings opportunities
Energy Efficient Lighting. Learn the fundamentals of energy efficient lighting in this course, and save more lighting energy!
Fundamentals of Energy Efficient HVAC. Knowing how to minimize HVAC energy use is core knowledge every energy manager, energy auditor, HVAC contractor or consultant needs.
Energy and Water Savings with Domestic Hot Water. This course covers both domestic hot water and water use more broadly. Being released shortly
Introduction to Energy Efficiency in Industrial systems. Covering electric motors, pumps and fans, refrigeration, steam and compressed air this course provides an introduction to these technologies and energy efficiency opportunities. Being released later in 2021
Section 3 – Prepare and submit an Investment Grade Audit
Successful completion of all eight courses listed above in the series, along with submission and satisfactory grading of a final assignment (an energy audit), will result in you being issued with a Certificate of Competence in Investment Grade Energy Auditing.
If you pass all the assessments in this course you will be issued with a Certificate of Competence in the Process of Undertaking an Energy Audit.
The assessment has been prepared by an expert, and is based on those key areas which demonstrate competence.
