Portfolio Manager Data Explorer User Guide

This guide introduces the features of the ENERGY STAR Portfolio Manager Data Explorer, which enables users to explore aggregated, anonymized data from EPA’s ENERGY STAR Portfolio Manager. It includes examples (at the end of the guide), demonstrating how to combine specific filters to get the most out of the data.

The Portfolio Manager Data Explorer offers a variety of metrics, and users can quickly see how the energy use of buildings varies based on the type of building, where it is located, its size, and other filters. Users can also download results for further analysis.

Portfolio Manager Technical Reference: Data Explorer

The ENERGY STAR Portfolio Manager Data Explorer houses energy data for over 150,000 U.S. commercial, multifamily, and single-family properties. The Data Explorer allows users to query this data and explore energy metrics such as Energy Use Intensity (EUI), ENERGY STAR Score, and Percent Electricity across a wide range of property types and characteristics. A variety of filters and metric display options provide customizable results. The tool is available at https://portfoliomanager.energystar.gov/dataExplorer.

Technical Reference: ENERGY STAR Score for U.S. Vehicle Dealerships

This document presents details on the development of the 1 – 100 ENERGY STAR Score for vehicle dealerships, which applies to buildings used for the sale of new or used light-, medium- and heavy-duty cars and trucks. The objective of the ENERGY STAR score is to provide a fair assessment of the energy performance of a property relative to its peers, considering the climate, weather, and business activities at the property.

ENERGY STAR Score for Single-Family Homes in the United States

The 1 – 100 ENERGY STAR score for Single-Family Homes applies to single-family detached and attached homes. The objective of the ENERGY STAR score is to provide a fair assessment of the energy performance of a property relative to its peers, taking into account the climate, weather, and activities at the property. To identify the aspects of building activity that are significant drivers of energy use and then normalize for those factors, a statistical analysis of the peer building population is performed.

Building Emissions Calculator: Technical Reference

This 10-page document provides a technical overview of the calculation methodology underlying the Building Emissions Calculator. The methodology is described in two main sections:

  1. Calculation of annual current/historical emissions for standard greenhouse gas emission accounting categories
  2. Calculation of annual emissions for a forecast year, based on user-specified assumptions, for the same accounting categories

This document also includes emissions-factor lookup tables in the appendix.
