There’s a pattern I’ve seen repeat itself across the energy efficiency industry. Someone comes into auditing with a strong background in one technology — HVAC, lighting, compressed air — and they do well identifying savings in that area. But outside it, they struggle. The savings opportunities that sit in the fundamentals — thermodynamics, heat transfer, the properties of air and water — stay invisible because the foundation isn’t there.
This course is about building that foundation. Not a deep academic dive into engineering theory, but a practical understanding of the energy fundamentals that underpin almost every savings opportunity you’ll encounter in the field.
It’s Part 3 of the Investment Grade Energy Auditor (IGEA) certification program and is accredited by ESTA (Energy Services and Technology Association).
This Energy Auditor Course aims to improve your way of thinking rather than a deep dive into energy fundamentals and technology. Our goal is to help you see more savings opportunities for your clients without being restricted to costly equipment upgrades.
Anyone implementing an ISO 50001 Energy Management System with the aim of achieving large improvements in energy productivity needs a good understanding of the fundamentals of energy.
Energy auditing sits at the intersection of physics, engineering, and commercial judgment. The physics part — the fundamentals — is what allows you to assess whether a savings claim is credible, identify opportunities others miss, and avoid being misled by products that promise results the science doesn’t support. Clean energy and energy efficiency are emotionally attractive fields, and that attraction brings its share of wishful thinking. A solid grasp of the fundamentals is your best defence against it.
Based directly on the course content, here’s what you’ll work through:
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. Advice that can bring in actual energy savings that help businesses grow and become more environmentally conscious.
Understanding the theory of energy fundamentals underpins a lot of this knowledge. If you don’t understand this theory, you’ll probably find it challenging to identify those large savings opportunities. 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 Energy Auditor Course, you’ll learn how to apply the first law of thermodynamics and determine the overall efficiency of a system or process. This course then covers the fundamentals of electricity and heat transfer. It looks at the properties of air and water.
Understanding these properties is essential if you want to master the HVAC&R system. With the global demand for cooling, 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 test your knowledge of the subject matter presented. If you pass the assessments, you’ll get a well-earned Certificate of Knowledge.
Continuing Education (CE) or Continuing Professional Development (CPD) refers to additional formal learning activities that are required to maintain a professional certification or accreditation.
CE or CPD comes in many names but represents the same thing. Here are some of them that may be used in your country:
Many of our courses provide Continuing Professional Development credits, points, hours, or units. To learn more about Continuing Education and Continuing Professional Development, please read here.
This course is aimed at people coming into energy auditing from a fairly narrow technical background, or those who haven’t had formal training in the fundamentals of electrical and mechanical engineering as they apply to energy. It’s for you if any of the following apply:
One thing worth being direct about: if you already have a strong grounding in thermodynamics, heat transfer, and electrical fundamentals as they apply to buildings and industrial facilities, this course may cover ground you’re already comfortable with. The introductory and process courses in the IGEA program are likely where you’ll find more value first.
Energy auditors with a deeper understanding of energy fundamentals can figure out how to save more energy than those who don’t. They’ll be able to scrutinize potential solutions with a critical eye.
Clean energy and energy efficiency are emotionally attractive to many people. Look at the sky-high valuations of many green technology companies. This emotional attraction also has financial attraction – “look at how much money you can save!” It can mean that wishful thinking replaces science.
A new product promoted by a very enthusiastic salesperson that promises to “slash greenhouse gas emissions” may attract energy users and even energy advisors. However, this product doesn’t actually work.
If you understand energy fundamentals, you should be able to see through this and avoid paying for equipment that adds no value to a facility.
If you want to further improve your energy systems management and optimization skills, we highly recommend completing our Investment Grade Energy Auditor (IGEA) certification.
By acquiring a IGEA certificate, you’ll be qualified to conduct professional energy audits for corporations, manufacturing plants, buildings, and other establishments in the industrial sector.
This Energy Fundamentals for Energy Auditors is the third course of the Investment Grade Energy Auditor (IGEA) Certification Program. Enroll Now

Bruce created a comprehensive course on all you need to know about energy calculations. It's a must-do course for engineers building energy data, analysis and calculations. I'm glad I did this course and better equipped myself. Will be one of my reference material in my work. High recommended.
The course explains very clearly the principles of thermodynamics and electricity. It helps performing energy calculations based on the energy fundamentals, heat transfer and electricity and gives enough opportunities to use those principles through various exercises. Lots of useful resources are available to look at different examples and expand the knowledge.
Energy fundamentals are the core principles — thermodynamics, heat transfer, the properties of air and water, and electrical theory — that underpin how energy is used and wasted in buildings and industrial facilities. Without them, it’s difficult to identify large savings opportunities or assess whether a proposed solution will actually deliver results. This course builds that foundation in a practical, applied way rather than as a theoretical exercise.
The first law of thermodynamics states that energy can’t be created or destroyed — only converted from one form to another. For energy auditors, this means every system has an input, an output, and losses in between. Understanding this allows you to calculate the true efficiency of a system or process and identify where energy is being lost. It’s one of the first things covered in this course.
HVAC and refrigeration systems typically account for a large share of energy use in commercial buildings — in many facilities, it’s the single biggest end use. To identify savings opportunities in these systems, you need to understand the properties of air and water, how heat transfer works, and how these systems respond to changes in load and operating conditions. This course covers those properties directly.
Auditors who understand energy fundamentals can look at a system and calculate its actual efficiency — then compare that to what’s theoretically achievable. That gap is where savings live. Without the fundamentals, you’re largely limited to obvious equipment upgrades. With them, you can identify systems-level opportunities that are often larger and lower cost.
