3 Common Energy Modeling Mistakes & How to Avoid Them
Whether you own a commercial property or manage building operations, energy efficiency has never been more important. Rising costs in the supply chain, growing sustainability requirements, and increasing energy prices mean that commercial buildings need to run smarter. Every kilowatt saved is money saved—and energy efficiency can directly impact your bottom line. However, identifying areas for improvement in large commercial buildings is not always straightforward. This is where energy modelling comes in.
What Is Energy Modelling?
Energy modelling is the process of creating a digital representation of a building’s energy use. It helps building teams review, analyze, and understand energy and financial data, allowing them to make smarter decisions. Through energy modelling, you can compare the performance of different systems, determine life-cycle costs, and plan energy-efficient design or renovation choices.
Traditionally, energy modelling was done manually—a complex and time-consuming process requiring specialized skills. Engineers had to input building specifications, mechanical systems, and operational schedules by hand, which could take days or even weeks. Today, automated energy modelling software makes this process faster, easier, and more accurate. With just basic building and system information, users can create detailed models in a fraction of the time.
Commercial buildings are often complex, and their energy needs vary depending on industry, use type, and building size. Understanding this complexity is key to making effective changes. To help building owners and engineers avoid common pitfalls, here are the three most frequent mistakes in energy modelling—and how to prevent them.
1. Limited or Ineffective Analysis
One common mistake is not analyzing energy models thoroughly. With so much data available, teams often focus only on obvious issues, such as regulatory compliance. While these “must-do” items are important, they are only the tip of the iceberg. Limiting analysis to these areas may leave major efficiency opportunities undiscovered.
Effective energy modelling means looking at results from multiple angles: energy use, operational costs, and long-term sustainability. By reviewing data in detail, you can identify inefficiencies, prevent future issues, and make better planning decisions.
Manual energy modelling can limit the depth of analysis because it is time-consuming and labor-intensive. Automated software, on the other hand, can highlight a wide range of efficiency strategies across mechanical systems, operational schedules, and building designs. Look for tools that provide clear, actionable insights tailored to your building type and industry. The goal is not just to collect data—but to use it to make smart, cost-saving decisions.
2. Reactive Maintenance
Another common mistake is using energy modelling only for reactive maintenance. Many teams run reports only when a problem arises, limiting their visibility into potential energy issues. This reactive approach makes it harder to identify trends early and prevent small issues from becoming costly problems.
To maximize energy efficiency, it’s important to take a proactive approach. Schedule regular energy modelling reviews across all buildings, even smaller ones. This helps your team catch inefficiencies early and ensures continuous improvement.
At NEO, we recommend setting a standardized cadence for energy modelling. Frequent monitoring and reporting not only improves efficiency but also reduces long-term maintenance costs. When you address issues early, you avoid expensive upgrades or repairs later on.
3. Wasting Time on Development and Analysis
Manual energy modelling can be extremely time-intensive. Creating, reviewing, and validating models can take 70–100 hours, with additional time needed for quality checks. Every efficiency measure added to the model requires careful validation. This process consumes team bandwidth and increases the risk of human error.
Automated energy modelling software reduces the time spent on development and analysis by up to 75%. Beyond speed, automation ensures that your workflow follows standard procedures, reducing mistakes and improving consistency. Designers no longer have to rely on “good enough” assumptions from previous projects. Automated modelling makes the best decisions clearer, based on the latest equipment efficiency, operational standards, and cost data.
