Performance Assessment

Collect and use current and historical energy data to form a baseline of your business’s energy performance


How it works

Collect Energy Use Data.

To lower costs and improve energy performance, it is important to understand your current and past energy use. Identifying the type and level of data to collect is the first step, and varies across organizations. While some businesses collect data from submeters, others look only at utility bills. Regardless of your approach, the data must be accurate and complete, and account for all the energy your organization has purchased and generated over the past two to three years.

Identify a Tracking System.

Tracking systems can range from simple spreadsheets to advanced monitoring systems. The type of system you use should be based on the type, level, and frequency at which you want to collect data. For example, if you want to track data at the equipment level, you may want to consider more advanced solutions, such as technologies that enable real time monitoring and predictive analytics.

Set Baselines. 

With the collected data, you will be able to establish a baseline of your energy performance—how much energy you use on average over a specific time period (e.g., daily, monthly, yearly). This baseline will serve as a starting point for establishing your energy saving goals and evaluating your ongoing energy performance. 

Benchmark Performance.

Benchmarking is another way to understand your business’s energy performance—comparing your energy use to that of similar organizations; your own past performance; or national, recognized standards. Consider using the ENERGY STAR® PortfolioManager®, a free online tool designed to benchmark your building’s energy use to that of similar buildings nationwide.

Analyze Data.

There are many ways to analyze energy use trends depending upon the data you collect. Analyses can identify metrics as varied as energy consumption peaks and valleys, areas of high-cost energy use, and differences between how different buildings and facilities are performing. Some organizations also participate in energy assessments or audits to analyze how specific equipment and systems are performing.


How you benefit:

  • Gain a baseline understanding of your current and historical energy performance
  • Establish a formal process for tracking and monitoring energy use
  • Identify opportunities to reduce energy use and operational costs
  • Make data-driven decisions to encourage continuous energy performance improvement

When you should consider it

Conducting a performance assessment may be good for your business if you are:

  • Determining your organization’s energy use at an enterprise or facility level
  • Forming and setting goals related to energy management
  • Identifying energy saving opportunities and improvements
  • Looking to implement a robust data collection and tracking system
