About the Data

Data in the Portfolio Manager Data Explorer comes from EPA’s ENERGY STAR Portfolio Manager benchmarking tool. The data in ENERGY STAR Portfolio Manager is entered by individual account holders voluntarily or, in some cases, as required by a local or state law. Except for properties applying for ENERGY STAR Certification (under 10,000 properties per year), EPA does not verify data entered in Portfolio Manager.

For the Portfolio Manager Data Explorer, EPA conducted a rigorous cleaning process, with the final data for each year representing over 150,000 U.S. properties of all types. While EPA has made every attempt to clean the dataset to remove duplicate entries, test properties, and entries with inaccurate data, EPA makes no claim of accuracy for the data included in the Portfolio Manager Data Explorer nor has EPA determined that this data is fully representative of the U.S. building stock.

To ensure privacy, searching for an individual property is not possible and a query must return 6 or more properties to show aggregated results. Any query which returns 5 or fewer properties in the results will display a dash. Results of filtering the data in the Portfolio Manager Data Explorer are aggregated to produce median, percentile, and average values, with the total number of observations from any query shown as a range. Data for each year may not consist of the same group of properties since not all properties benchmark in Portfolio Manager every year.
