What Energy Auditors do

Energy auditors review how energy is utilized in residential, commercial, and industrial properties. Their task revolves around identifying areas or equipment where energy waste occurs.

They utilize diagnostic and measurement equipment to gather data within a facility or building. After which they use calculations to quantify their findings. Finally, they offer suggestions for optimizing energy use within the facility.

Because of the hands-on nature of the job, an energy auditor needs to have an energy management skillset. They must be knowledgeable about sub-metering and sampling techniques.

When working as a contractor, you create a plan to improve the energy efficiency of a home or small structure.

What is Energy Management?

Energy management is the practice of monitoring and improving energy consumption in a facility.

This process is not limited to the upgrading of equipment and design of the facility. It also focuses on other aspects, such as the energy efficient practices and behaviour.

Some of the steps involved in energy management:

Engage with top management; top management needs to support and drive an energy management program for it to be most effective.
Gather and analyze data continually.
Identify optimization opportunities to improve energy efficiency, such as equipment re-scheduling.
Plan and implement energy optimization solutions.
Ensure that staff implement energy efficient practices, and that appropriate training is provided
Monitor results, and take corrective action where solutions aren’t operating as intended.
Use a “Plan – Do – Check – Act” cycle on an on-going basis to get continual improvement.

Energy management is crucial to any business or organization because it reduces risk, carbon emissions, and energy costs.

How About an Energy Manager?

Energy managers are employed to implement an Energy Management System (EnMS). They plan and execute energy-efficient measures to save money for the business or organization that employs them.

Additionally, they are responsible for continually monitoring, evaluating, and revising the energy management activities in order to meet energy reduction targets.

Meanwhile, some companies put energy managers in charge of a small group. Thus, aside from calculative and analytical skills, they are also expected to have leadership skills.

What Does an Energy Manager do?

Energy managers wear different hats depending upon the company. They often recommend strategies, using the data provided by energy auditors and building inspectors.

Furthermore, an energy manager often reports their activities to the company’s top management or board of directors. They are responsible for communicating with the building’s utility and maintenance staff about new energy-saving measures, and ensuring that projects are well implemented.

Unlike the strong technical and engineering focus of energy auditors, energy managers are involved more in planning and management Energy managers may use software to analyze and develop energy management plans and track performance.

The Difference Between an Energy Auditor and an Energy Manager

Energy auditors and energy managers vary in several ways. However, they have similarities, especially in their roles within a company.

An energy auditor focuses on fieldwork and collecting data, using numerous tools. Meanwhile, an energy manager’s work centers around management and planning.

The following are some of the differences between an energy auditor and an energy manager:

Role or Position	Primary Responsibility	Core Skills
Energy Auditor	Their work entails auditing commercial and industrial properties to identify and quantify where energy is used, and opportunities to save energy	– Knowledgeable in energy using technologies and systems (e.g. HVAC, lighting, steam, motors etc) – Ability to use multiple measurement and diagnostic tools
Energy Manager	Their work focuses on effective energy management through planning, staff engagement, data analysis and project management.	– Planning – Engagement and project management Knowledgeable of energy management systems – Must have good quantitative and technical skills

Energy Auditor Prerequisites

When pursuing an energy auditor certification, traditional certifying bodies such as AEE have specific prerequisites in terms of education and experience.

However, Sustainability Education Academy (Sustemy)’s Investment Grade Energy Auditor (IGEA) Certification offers an alternative pathway that takes into account the needs of young graduates and provides a more flexible approach to eligibility requirements.

Traditional Prerequisites for Energy Auditor Certification:
