Understanding where and when your business uses energy is essential and empowering. It gives you the power to find the best ways to save money.
While energy bills can give you some of this information, more detailed data and assessments will provide you with a clearer picture of energy use, boosting your confidence in your decision-making.
A complete guide to energy audits for industrial facilities can help you understand how your company consumes energy and point out areas where you could save. This can lead to less energy use, better productivity, and chances to improve your operations.
Energy audits can be done within your company, but if you don’t have the right skills in-house, you can hire outside experts or energy service companies to handle part or all of the audit.
What is Energy Audit: A Comprehensive Guide
An energy audit for an industrial facility is a detailed process for analysing energy consumption in a factory or plant and identifying ways to use that energy more efficiently.
It is like a health check-up, but instead of checking a person’s body, it evaluates the energy systems of a building or facility.
The main goal of an energy audit is to find areas where energy is wasted and suggest changes that can save money, reduce environmental impact, and improve overall performance.
How Energy Audits Work
The process starts with inspecting the facility to understand how energy flows. This involves examining machinery, lighting, heating, cooling, and other energy-consuming equipment.
Specialists will also examine the organisation of processes like manufacturing or storage to identify opportunities to improve their energy efficiency.
Next, data about energy usage over time is collected. This data usually comes from electricity bills, gas consumption records, or even specialised meters installed on the equipment.
By studying this data, energy auditors can determine where most energy is used and whether it is used efficiently.
Key Steps in an Energy Audit
Site Inspection: The auditors visit the facility to understand its layout, machinery, and energy systems. They might also examine insulation, air leaks, and outdated equipment.
Data Collection includes reviewing utility bills and analysing how energy consumption varies throughout the day or season.
Performance Testing: Some audits might include measuring equipment efficiency, such as motors, boilers, or HVAC (heating, ventilation, and air conditioning) systems, working.
Analysis: After collecting all the data, the auditors analyse it to identify trends, inefficiencies, and areas for improvement.
The auditors provide a detailed report that includes suggestions for reducing energy use. These recommendations include upgrading to energy-efficient machinery, improving insulation, or using renewable energy sources like solar panels.
Benefits of an Energy Audit
One of the most significant benefits of an energy audit is saving money. By reducing energy waste, businesses can lower their utility bills. This is also good for the environment, as less energy means fewer greenhouse gas emissions.
Energy-efficient equipment saves money and leads to smoother operations for industries. It often requires less maintenance and lasts longer, providing a long-term return on investment and instilling confidence in the decision to upgrade.
Additionally, many governments offer incentives, such as tax breaks or subsidies, for companies that make their facilities more energy-efficient. This can further reduce the cost of implementing the changes suggested in an energy audit.
Importance of Energy Audits for Industrial Facilities
Industrial facilities typically use more energy, much more than offices or homes. However, this also means that even minor improvements in energy efficiency can lead to significant cost savings, providing a strong motivation for conducting energy audits.
For example, replacing old motors with energy-efficient ones or improving equipment scheduling can make a big difference. These measures also help companies stay competitive, especially in industries where energy costs are a large part of overall expenses.
In summary, an energy audit is a systematic way to understand and improve energy use in an industrial facility. It helps save money, supports sustainability efforts, and enhances operational reliability.
Conducting an in-house energy audit means examining how your business uses energy to find ways to save money.
While energy bills can provide some clues, gathering and analysing more detailed data will help you better understand energy consumption.
However, conducting an in-house energy audit can be challenging due to the complexity of energy systems and the need for specialised knowledge. It’s essential to be prepared for these challenges and consider seeking professional assistance.
Conduct an In-house Energy Audit
Access Energy Data
To get a complete picture of your electricity and gas use, you’ll need at least 12 months of data showing how your energy use changes over time.
The billing data can help you identify which processes in your company use the most energy. You can obtain this information directly from your energy supplier or have someone else access the data.
You can rent a meter to measure short-term energy use or install meters to track specific periods. When reviewing the results, consider daily, monthly, or seasonal changes.
Energy monitors show your energy use and cost in real time. Some energy suppliers offer free energy monitoring, and apps are available for Apple and Android devices. You can also find plug-in monitors for your business.
You can visit the Victorian Energy Saver website to learn how to access and understand energy data.
Analyse your Energy Baseline
Next, analyse your energy baseline. This will help you understand the connection between your business’s energy use and activities and link energy costs to business output.
Common ways to analyse energy data include:
- Graphing energy use over time to see patterns, considering seasonal, monthly, weekly, daily, or even hourly usage
- Plotting energy use against production or other factors
- Benchmarking your energy performance to see if a process or business unit is working at its best or to compare different sites
Monitor Your Data
Choose the Correct Type of Energy Audit
Type 1 (Basic Energy Audit)
This is a simple review of how much energy your business uses, with a rough estimate of possible savings and relatively quick payback periods.
These audits are good for small businesses but can also help larger ones if they haven’t checked their energy efficiency.
Type 2 (Detailed Energy Audit)
This audit provides a more thorough analysis of your business’s energy use. It calculates potential savings based on specific data and equipment used at each location.
It also includes a financial evaluation of energy-saving opportunities to help you prioritise them. This type of audit usually doesn’t require extra measurement tools.
Type 3 (Precision Subsystem Audit)
This audit focuses on a specific part of your system, such as boilers or air compressors. It involves additional measurements to provide more precise data on possible savings. This audit is best for larger businesses with specialised equipment or extensive production facilities.
Tips for Doing an Industrial Energy Audit for Your Business
There are several ways to conduct an energy audit, and it’s important to remember that every business is unique and has unique energy needs.
While it is best to hire a professional to conduct an energy audit, you can do some things yourself to get started.
Here are some tips to help you:
Check Equipment Maintenance: Make sure your equipment is regularly serviced and follows the recommended maintenance schedule.
Evaluate Heating and Cooling Appliances: Determine the age of your heating and cooling systems and check if they need replacing.
Monitor Room Temperature: Make sure you’re only heating or cooling the rooms that are being used.
Use Timers: Check if timers are installed in different parts of your building to control energy use.
Look for Air Leaks: Search for any leaks that could be wasting energy.
Install Programmable Thermostats: Use programmable thermostats to control heating and cooling more efficiently.
Set Temperature Settings: Set your heating or cooling temperature between 24 and 27°C in winter and 18 and 21°C in summer.
Proper Placement of Thermostats: Ensure thermostats are placed correctly, away from direct sunlight or heat sources.
Insulate Ductwork: Insulate your ductwork to reduce energy loss.
Consider Variable Speed Equipment: Replace fixed-speed motors with variable-speed equipment.
Improve Airflow: Make sure no blockages prevent proper airflow in your building.
Assess Water Heating: Check how much energy is used for water heating and if it matches your needs.
Evaluate Lighting: Hire an expert to ensure the right lights are installed in the right places.
Use Task Lighting: Consider using task lighting to avoid lighting large areas unnecessarily.
Switch to LEDs: Use LED lights for better energy efficiency across your business.
Maximise Natural Light: Find ways to use natural sunlight more effectively in your building.

How Should the Measles/Mumps/Rubella Vaccine Be Administered? Should You Ask a High School Baseball Coach?
There are so many things going wrong in this country simultaneously that it’s hard to list them all.
Here’s something that no one could have seen coming: (see short video here) crackpot politicians giving parents insane medical advice about how to care for their children.
If I told you that our country’s parents were making decisions on vaccinating their children based on information provided by figure skaters or lawn mower salesmen, you wouldn’t believe me.
But the case is actually worse; it’s coming from the White House.
In this short video on the bombing of ships leaving Venezuela, President Trump asserts that drug overdoses took like lives of more than 350,000 people last year, a figure that, according to the CDC, is actually 79,383.
In any case, the video fails to mention that executing people who have not been charged with and convicted of a crime is a violation of both domestic and international law.
Do Americans Approve of Our Country’s Execution of Innocent People?
Keep in mind that, in 2020, more than 70 million voters cast their ballots for Trump, who, though he is a pathological liar, is 100% trusted by his supporters. When Trump said the election was rigged, the vast majority of these folks believed him. Even today, more than five years later, there are still millions of people who believe there was rampant voter fraud in the election.
Now, is storming the Capitol and beating up/killing law enforcement personnel an acceptable solution? It wouldn’t be for you or me, or most people, but imagine you’re an uneducated white-supremacist MAGA guy, and your president is telling you to do whatever’s necessary to prevent the election from being certified.
These are people who were so desperate to hang Mike Pence that the vice president had to be escorted out of the Capitol building to a secret and secure location, so he didn’t end up at the end of a rope.
When asked about this, Trump replied, “Maybe he deserved it.” To anyone trying to make sense of this, remember that you’re dealing with a deeply disturbed individual, and many millions of truly pathetic people who believe his is an honest and effective servant of the American people. In congress, we have a couple of hundred of the most terrible butt-kissers imaginable, all clamoring to curry favor with him.
