Energy management is no longer just about tracking overall consumption. To truly optimise energy use, you need to go beyond the main meter. Submetering is a powerful tool that provides detailed insights into where energy is being wasted, allowing you to act quickly and effectively. Here’s how submetering works, where to install it, and how to leverage the data for maximum impact.
What Is Submetering and How Does It Work?
Submetering involves installing additional meters to measure energy use at a more granular level. Unlike a main meter, which tracks total energy consumption for a building or facility, submeters focus on specific areas, systems, or equipment.
For example, you can install submeters on HVAC systems, lighting circuits, or production lines. These meters collect real-time data, showing exactly how much energy each component is using. This level of detail allows you to identify inefficiencies, track trends, and pinpoint waste that would otherwise go unnoticed.
Submeters work by measuring energy flow through electrical circuits, gas lines, or water pipes. The data is then transmitted to a central system, where it can be analysed and visualised. With the right tools, you can turn this raw data into actionable insights.
Where to Install Submeters
The key to effective submetering is strategic placement. To maximise the value of your investment, focus on areas or systems with high energy consumption or known inefficiencies. Here are some common places to install submeters:
- Process Lines: In manufacturing or industrial settings, submeters can monitor energy use for specific production lines or machines. This helps identify which processes are consuming the most energy and whether they’re operating efficiently.
- HVAC Systems: Heating, ventilation, and air conditioning often account for a significant portion of energy use in commercial buildings. Submeters can track energy consumption for individual units, helping you detect issues like overuse or malfunctioning equipment.
- Lighting Circuits: Lighting is another major energy consumer, especially in large facilities. Submetering can reveal whether lights are being left on unnecessarily or if older, inefficient fixtures need to be upgraded.
- Specialised Equipment: For businesses with unique energy needs, such as data centres or laboratories, submeters can monitor specific equipment to ensure it’s operating within acceptable parameters.
By targeting these areas, you can gain a clearer picture of where energy is being wasted and prioritise improvements.
Benefits of Submetering: Granularity, Accountability, and Fault Detection
Submetering offers several advantages over traditional energy monitoring methods. Here are the top three benefits:
- Granularity
- Submeters provide detailed data that goes beyond the big-picture view of a main meter. This granularity allows you to break down energy use by department, system, or even individual pieces of equipment. With this level of detail, you can identify inefficiencies that would otherwise remain hidden.
- Accountability
- When energy use is tracked at a granular level, it’s easier to assign responsibility. For example, if one department’s energy consumption is significantly higher than others, you can work with them to identify and address the issue. This fosters a culture of accountability and encourages everyone to contribute to energy-saving efforts.
- Fault Detection
Submeters can help you spot problems early. For instance, if a piece of equipment starts consuming more energy than usual, it could indicate a mechanical issue. By catching these faults early, you can avoid costly repairs and downtime.
How to Read and Act on Submeter Data
Collecting data is only half the battle. To truly benefit from submetering, you need to know how to interpret the data and take action. Here’s a step-by-step guide:
- Analyse Trends
- Look for patterns in the data. Are there spikes in energy use at certain times of day? Do specific systems or areas consistently consume more energy than expected? Identifying these trends is the first step toward understanding where energy is being wasted.
- Set Benchmarks
- Use the data to establish benchmarks for energy use. For example, you might determine that a certain production line should consume no more than a specific amount of energy per hour. These benchmarks can help you measure progress and identify deviations.
- Identify Inefficiencies
- Compare actual energy use to your benchmarks. If a system or piece of equipment is consuming more energy than expected, investigate the cause. It could be due to outdated technology, poor maintenance, or operational inefficiencies.
- Implement Solutions
- Once you’ve identified the source of energy waste, take corrective action. This might involve upgrading equipment, adjusting operating schedules, or improving maintenance practices. The goal is to eliminate inefficiencies and reduce energy consumption.
- Monitor Progress
After implementing changes, continue to monitor energy use with your submeters. This will help you determine whether your efforts are working and identify any new issues that arise.
Software That Simplifies Submeter Analysis
Managing submeter data can be overwhelming, especially in large facilities with multiple submeters. That’s where energy monitoring software comes in. Tools like Priority Metrix simplify the process by collecting, analysing, and visualising submeter data in one place.
With the right software, you can:
- Visualise Data: Create easy-to-read charts and graphs that highlight trends and anomalies.
- Set Alerts: Receive notifications when energy use exceeds predefined thresholds.
- Generate Reports: Produce detailed reports to share with stakeholders or use for compliance purposes.
- Automate Analysis: Use built-in algorithms to identify inefficiencies and recommend solutions
By leveraging these tools, you can turn submeter data into actionable insights without spending hours poring over spreadsheets.
Conclusion
Submetering is a game-changer for energy managers who want to go beyond the basics. By providing detailed insights into energy use, submeters help you pinpoint waste, improve efficiency, and reduce costs. Whether you’re monitoring HVAC systems, lighting circuits, or production lines, submetering gives you the data you need to make informed decisions.
With the right placement, analysis, and software, submetering can transform your approach to energy management. Don’t just track energy use, understand it, optimise it, and take control.
