ASHRAE's Building EQ Portal provides a quick energy analysis that benchmarks a building's energy performance. Building EQ assists in the preparation of an ASHRAE Level 1 Energy Audit to identify means to improve a building's energy performance including low-cost, no-cost energy efficiency measures and an Indoor Environmental Quality survey with recorded measurements to provide additional information to assess a building's performance.

Two different evaluations can be used independently to compare a candidate building to other similar buildings in the same climate zone or together for an assessment of a building's design potential compared to actual operation:

1. In Operation compares actual building energy use based on metered energy information.
2. As Designed compares potential energy use based on the building's physical characteristics and systems with standardized energy use simulation.

The ASHRAE Building EQ portal is able to import a gbXML file to populate basic building information.
