IGEA Final Assessment
When an IGEA undertakes an energy audit, following the thorough process taught during the IGEA training, all parties can have confidence in the business case presented in the audit.
This reduces risk, providing greater certainty of the outcome of energy efficiency upgrades. And ultimately, it leads to increased investment in energy efficiency, leading to increased financial and carbon savings.
Investment Grade Energy Auditor Final Assessment Summary
- This course is where you upload an Investment Grade Audit, to establish your competency as an Investment Grade Energy Auditor.
- Your audit will be assessed by an expert energy engineer against a 100 point checklist.
- You must have successfully passed the earlier courses in the Energy Audit series and have Provisional IGEA certification.
Investment Grade Energy Auditor Final Assessment Description
An energy audit is an assessment of a facility to identify how much energy it uses, where energy is used, and to present a business case for undertaking upgrades that reduce energy use. Typically, the whole site is assessed, with multiple savings opportunities identified across all areas of energy usage.
An Investment Grade Audit (IGA) is one in which the business case in the audit is sufficiently comprehensive and robust that it can be trusted when making an investment decision. An IGA is also known as a Detailed Feasibility Study (DFS).
An IGA is central to an Energy Performance Contract (EPC). In an EPC, an Energy Services Contractor (ESCO) delivers guaranteed energy savings in return for a fixed investment. The ESCO will conduct an IGA or DFS and use this as the basis of their guarantee to determine the investment requirement.
A bank or finance corporation looking to finance energy efficiency upgrades would similarly expect an energy audit undertaken to be of an investment grade standard.

Anyone wanting reasonable assurance that an energy audit provides a trustworthy business case that de-risks investments to reduce energy costs and greenhouse gas emissions can benefit from an IGA.
An Investment Grade Energy Auditor (IGEA) goes through comprehensive and rigorous training and assessment. The assessment includes marking an IGA prepared by the IGEA (this IGEA assessment). It is a far more thorough assessment than many other energy efficiency and energy auditing certifications.
Investment Grade Energy Auditor Certification Eligibility
This final assessment is only accessible to those who have successfully completed the eight courses in the energy audit series and who are a Provisional Investment Grade Energy Auditor.
Certification
If you pass this course, you will be certified as an Investment Grade Energy Auditor. An expert energy auditor has prepared the assessment, and it is based on key areas that demonstrate competence.
