Commercial Energy Audits

A Surefire Way to Improve Your Business’s Energy Efficiency

ECOcentrix performs independent commercial energy audits on a variety of buildings, from single-family homes to multi-story high rises. 

Our goal is to measure your current energy usage, set a baseline for future consumption, and identify areas where your facility can save energy. 

We have completed numerous ASHRAE Level 1 and Level 2 energy audits in St. Louis, MO and the Midwest.

1st Step

Collect Utility Usage Data

For at least 36 months

This data allows us to assess your building’s energy consumption rate and identify seasonal trends.

During the site visit, we will evaluate the commercial building envelope, lighting, HVAC, domestic water use, and potential improvement areas.

We will also review available building plans, information, and staff interviews to get a better understanding of how your facility functions as a system.

Energy Audit Report

Unveiling Cost-Effective Conservation Strategies

The audit report will outline Energy Conservation Measures (ECMs), their projected implementation costs, expected lifetimes, and the corresponding estimated energy usage. We will also provide you with recommendations for implementing the most cost-effective ECMs.

Commercial energy auditing is a valuable investment for businesses looking to improve energy efficiency. 

By identifying and implementing energy efficiency measures, you can save money on your energy bills, reduce your environmental impact, and improve your bottom line.

How ECOcentrix Conduct Commercial Energy Audits

1

Data Collection and Analysis

Prior to the site visit, gather utility usage data for a minimum of 36 months. This step is crucial to assess the building’s energy consumption rate and examine seasonal energy usage trends.

2

Comprehensive Site Evaluation

During the site visit, conduct a thorough assessment of various aspects of the building. This includes evaluating the building envelope, lighting, HVAC (heating, ventilation, and air conditioning), and domestic water use. We focus on identifying potential areas for improvements and energy conservation.

3

Detailed Reporting and Planning

Post-evaluation, compile a comprehensive study outlining Energy Conservation Measures (ECMs). This report will detail the projected implementation costs, expected lifetimes of the ECMs, and their corresponding estimated energy savings. To enhance the accuracy of the report, review available building plans, gather information, and conduct staff interviews to understand how the facility functions as a system.

When I wanted to have an Erie Metal Roof put on my home, our Solar Panels needed to be remove and reinstalled on the new roof. ECOcentrix was able to complete both tasks working around the installation of our Erie Metal Roof. (June/July 2025)

Eco centrix did a great job on our siding and overhang. Trevor cleaned up and was careful to get the nails and debris. Thanks because my wife is happy now.

ECOcentrix just finished our new roof in less than a day and a half on our large 1.5 story house in Creve Coeur. Because we have 2 dogs, it was important to us that they ensure that our lawns get cleaned afterwards, and indeed, their workers spent a lot of time scouring to pick everything up completely! They were hard-working & professional in every aspect, and the project manager Trevor is especially helpful and easy to work with. We highly recommend this company!!!

Very professional team. Entire process was done with customer service in mind. Communication was exceptional, install was great and after install support exceeded all expectations. Highly recommend this company and solar installation even with tax benefits going away for home ownership. Savings will pay for the system in a few years and you are never impacted by rate increases.

In an effort to take advantage of the Illinois subsidized solar system program for our business, we responded to a few different solar system installer’s ads. Aaron, from Ecocentrix, stood out as the one person who seemed to be able to sit down with us and REALLY explain, in depth, just about everything there was to know about solar and how the Illinois Shines program worked. He was so knowledgeable and worked with us in every aspect, from the application for the solar program, to the application for financing, to signing all of the documents, to keeping everything on track in order to meet deadlines and make it all happen.
Very shortly after the installation was complete a tornado ripped our roof off of our building and the entire solar system with it. Aaron and his team were ‘on it’ almost immediately, surveying the situation and offering their assistance. Happy to say, with their dedication, everything is all replaced and running smoothly now.
We have only experienced about 1 month of solar usage so far, but have noticed a significant difference in our electric bill, of about 80%. We don’t have as many daylight hours or a lot of sunshine now, but being newly installed, we expect an even greater difference in the future.
We would absolutely recommend Ecocentrix for your solar projects. They offer the best quality product and they have the knowledge, the expertise, and experience to properly install it.

I went through ECOcentrix for my roofing and solar projects and I could not recommend them more. I had an insurance claim for my roof and they handled it very professionally and made sure I was taken care of and getting everything I could for it. My solar was turned on a couple days ago and I could not be happier with how it turned out. Everyone that I worked with was kind, professional, and caring. They treated me like a person and not just a check. I will go through ECOcentrix for anything they offer. They have made a customer for life.

Ecocentrix came highly recommended by the guys at Erie roofing so I gave them a shot. Aron from Ecocentrix worked with my schedule and planned a very informational meeting explaining the product and process of going solar. The whole process took close to a month as they explained it would, nothing was rushed. They came out and assessed our home to be sure it was right for solar, and designed the best set up for us. Sarah at Ecocentrix kept us up to date with the process making sure we knew what and when to expect the installation. Before we knew it, an Ameren technician was here to inspect it for start up. The Ameren tech assured us that the panels were producing well, and was impressed by the simplicity of the panel, commenting that it was a pretty straight forward design. We are very impressed with Ecocentrix’s team of professionals and are happy that we made the switch to solar!
Thanks Aron, Sarah, and Ecocentrix team!

I normally don’t make to many reviews, but Aaron and the team with Ecocentrix was amazing through the entire process and I have to share that. Everyone was very informative, knowledgeable, friendly, professional, and patient throughout the process. The process normally would have taken 3 months, but it took a bit more for me because a new roof was needed. Once that was installed the process to install the panels were pretty fast because they had already did their due diligence having everything in order before they installed everything.

Anytime I had questions the team would always be there to answer those questions promptly. They also made sure I was always informed of what was going on and the next steps in the process as well. Keeping an open line of communication was very important to me as I was very new to this process and it made me very appreciate of that fact.

The solar panels have worked wonders as well since they have been installed. We’ve seen a major decrease in the electric bill just as they said it would and it feels like a burden with the electric bill has been lifted. Thank you guys for what you do! I’d recommend everyone to ECOcentrix!

I spent so much time trying to decide on solar (way too many plans/systems and misinformation). My wife suggested we speak with Jonathan from ECOcentrix. She has a few friends who went through them for solar and had great things to say about them. I’m so glad we did! 5 star company, quality material, labor and excellent customer service. They truly believe in what they are doing and they work hard to be the best for their customers! I am confident this company will still be around years from now so my system is in great hands. Give them a call. I believe you will not be disappointed! Thank you Mollie, Aaron, Jonathan, Mike & Sarah.

Mollie and Aaron spoke with me at length about whether solar would be a good fit for my new home. They were thorough and honest, ultimately helping me to see that it’s not likely a good fit for my home at this time. They’re helping me to find an energy auditor instead, to see how we can improve our energy use. They genuinely care about their customers, speak to the client’s specific and individual situation rather than a universal sales pitch and were able to explain everything in great detail. Thank you Aaron and Mollie!

ECOcentrix did everything they promised and more. Our system is producing as planned and we can monitor it on our app. We have enough surplus to replace appliances with electric as they need replaced. Love it!!

Very knowledgeable about the industry. It is good to have someone who can help with filing all the applications and paperwork. Also they know of all available incentives to go solar. Check out their energy audit that is a part of their program. Very impressive component that other solar companies simply do not have.

It took me a while to trust what I was being told about going solar. With so much misinformation out there, I was leery of taking the leap. However, the overall care and education we received from ECOcentrix Energy Solutions, combined with their thorough energy audit and exceptional solar panel installation, was truly unmatched!

From the start, Molly, Aaron, and their team, along with our sales rep Johnathon, made sure we fully understood the process. They answered all our questions and eased our concerns every step of the way. The solar panels they installed not only look sleek but have drastically improved our home’s efficiency—and we’re already seeing significant savings on our monthly power bills!

If you’re hesitant like I was, I highly recommend reaching out to ECOcentrix Energy Solutions. Their friendly, knowledgeable team will provide the education and guidance you need to make an informed decision. Give them a call today and start your journey toward energy savings and sustainability!

This company is top notch. Great service from the start to finish of our solar job. The presentation was understandable and accurate to what we could expect. The plan for making our home more energy efficient was easy to do with Aaron and Molly’s help step by step. Streib electric assisted with the installation and were professional as well. Would definitely recommend this company for Energy solutions and solar. Very happy we met them at a home show.

FAQs

A commercial energy audit is a detailed assessment that analyzes a building’s energy usage to identify opportunities for conservation. The audit examines systems such as lighting, HVAC, water use, and building insulation, allowing businesses to save on energy costs while reducing their environmental impact.

Conducting an energy audit allows businesses to pinpoint energy inefficiencies, leading to cost savings, increased operational efficiency, and reduced energy waste. It can also enhance building comfort for occupants and improve the overall performance of heating, cooling, and lighting systems.

Commercial energy audits are beneficial for a wide range of buildings, including small offices, large commercial facilities, and multi-story high rises. ECOcentrix has extensive experience working with buildings of all types in the Midwest, helping businesses of various sizes improve their energy use.

The audit process begins with collecting at least 36 months of commercial utility data to analyze historical energy use. A comprehensive site evaluation follows, assessing building features such as insulation, lighting, and HVAC systems. Finally, the team compiles a detailed report with actionable recommendations to improve energy efficiency.

The time required for an energy audit depends on the building’s size and complexity. Data collection and initial site evaluations may take a few days, while preparing the final report may take additional time as it includes specific cost-saving recommendations and projected savings.

ASHRAE Level 1 and Level 2 audits are standards for energy audits for businesses that differ in scope. A Level 1 audit provides an overview of energy use and identifies simple, cost-effective energy-saving measures. A Level 2 audit goes deeper, offering detailed recommendations and cost analyses for more significant energy improvements.

ECMs are specific strategies identified during the audit to reduce energy consumption. These measures could include upgrades like energy-efficient lighting, HVAC improvements, or enhanced insulation. Each ECM comes with estimated implementation costs, expected savings, and a payback period to help prioritize energy investments.

Yes, the audit report will include detailed cost estimates for each recommended ECM, along with the anticipated annual savings and payback period for each improvement. This allows businesses to make informed decisions about which measures offer the most significant financial and energy-saving benefits.

Absolutely. By implementing the recommended energy conservation measures, businesses can lower their energy consumption, which reduces greenhouse gas emissions. This not only helps with sustainability goals but also demonstrates a commitment to environmental responsibility.
