Performance indicators help you evaluate the energy efficiency of your building. For example, you can see if your building uses more energy per square foot than similar buildings, or you can spot suspicious seasonal or daily spikes in energy use. Three types of tools will help you develop performance indicators and analyze your building's performance:
The links below take you to pages that explain each type of tool, explain best practices for using the tools, show you how to collect the data required by these tools, and help you select the best tool(s) for each of your buildings.
This helps evaluate your building's energy use over time to provide clues to hidden problems such as unusually high consumption during a particular season of the year.
This helps compare the energy performance of your building with its performance during a previous time period, or with the performance of other buildings in your management portfolio, or with the average performance of similar buildings in a broad regional or national database such as that provided by EPA's Energy Star Portfolio Manager.
This helps you to use data measured over time as a diagnostic tool. This may include data from utility interval demand meters, DDC, and electrical submeters installed on building equipment.
Several software tools offered by utilities and public and private groups can help you track utility bills, benchmark your building, and trend-log data.
