Difference between Preliminary Energy Audit and Detailed Energy Audit

Have you ever noticed that your energy bill seems to be higher than usual?

Or maybe you’ve been getting a lot of energy-related offers in the mail, and are wondering what they mean.

If so, you may be interested in learning more about energy audits! An energy audit is a process that can help identify if there are any problems with your home’s energy use or efficiency, and it’s often performed by an auditor who will work with you to make sure everything is running as efficiently as possible so that your bills are lower.

The main difference between preliminary and detailed energy audits is that preliminary energy audits are done to assess the scope of an existing building, while detailed energy audits focus on the actual systems and how they work.

Before we move to the differences, let’s understand what are Preliminary Energy Audit and Detailed Energy Audit:

  • Preliminary Energy Audit: A preliminary audit is a quick, on-site inspection of your facility that can tell you what areas of your building are using the most energy. It doesn’t include any recommendations or solutions for reducing your energy usage—it just shows you what needs to be improved, and how much money it will save you.
  • Detailed Energy Audit: A detailed audit goes into much more depth than a preliminary audit, but it’s still not as in-depth as a full-scale energy audit. It’s the kind of thing that an HVAC company might do to get an idea of what kind of upgrades they could recommend to reduce your building’s overall energy usage.

Major differences between Preliminary Energy Audit and Detailed Energy Audit

Preliminary Energy Audit Detailed Energy Audit
A preliminary energy audit is usually done by an engineer who will go around your building and look at how much energy it uses in different areas. A detailed energy audit is done by someone who can provide more specific recommendations for how to reduce your overall energy usage.
A preliminary audit will give you an overview of how much energy your facility uses as a whole. A detailed audit will give you more information on individual pieces of equipment or processes in the building.
Preliminary energy audits serve as an overview to help you understand where your biggest opportunities for cost savings lie—but they don’t go into as much detail as a detailed audit would. A detailed audit will show you how much money you’re spending on electricity each month and how much it costs to heat or cool each room individually; then they’ll show you how much money could be saved if those costs were reduced by just 10% or 20% or 30%.
In a preliminary energy audit, the building’s components are not as thoroughly examined. In a detailed energy audit, the building’s components are thoroughly examined.
The results from this type of diagnostic exam do not provide detailed information about your facility’s problems, but it does give you an idea of where you should focus your time and money when it comes time for repairs or upgrades. A detailed energy audit will provide much more information about how well (or poorly) certain areas are performing within your business or home.

That’s it.
