By providing information about a building’s energy use and comparing its performance to similar buildings, benchmarking empowers building owners, managers, and other stakeholders to make more informed decisions, identify opportunities to improve energy and water use in their buildings, and save money. Evidence of these benefits is already available: by analyzing data from over 35,000 buildings that used the free EPA tool, ENERGY STAR® Portfolio Manager and received an ENERGY STAR® score from 2008 to 2011, US EPA found that average energy use declined by 7%. For more benchmarking trends, visit US EPA’s DataTrends Series, found at www.EnergyStar.gov/DataTrends.

City-owned properties and large commercial properties (20k sq. ft. +) will be the first properties required to benchmark. Smaller commercial properties and multi-family properties will be phased over time.
This table shows the exact square footage of properties required to benchmark and by when:
No, none of these residential buildings are required to benchmark under Ordinance No. 05.
Building owners required to benchmark under the Building IQ program need to input their property information and annual utility bill data into the EPA's ENERGY STAR® Portfolio Manager tool and share the information with the City of Aspen. The City's partner, the Community Office for Resource Efficiency (CORE), is available to help with this entire benchmarking process. Get started today by clicking here.
Owners of commercial properties 20,000 square feet and larger are required to get a building assessment, which looks at building performance and energy and water usage, and can be done for free through our partners at CORE. To schedule an assessment, click here.
For all help with benchmarking, contact CORE.
See table below for the list of properties 20,000 square feet or larger. The properties on this list have to benchmark and share the report with the City of Aspen by December 1, 2022.

ENERGY STAR® Portfolio Manager is a free online tool developed by the U.S. Environmental Protection Agency (US EPA) that allows you to track and assess energy and water use across your entire portfolio of buildings in a secure online environment. With Portfolio Manager, you can calculate the building's energy performance, compare it with similar buildings and monitor it over time. When you benchmark a building in Portfolio Manager, one of the key metrics you'll see is energy use intensity, or EUI.
The EUI expresses a building’s energy use as a function of its size or other characteristics. For most property types in Portfolio Manager, the EUI is expressed as energy per square foot per year. It’s calculated by dividing the total energy consumed by the building in one year by square footage. For many building types, Portfolio Manager calculates the ENERGY STAR® rating, which indicates how efficiently buildings use energy on a 1-100 scale, where a score of 50 indicates average energy performance. Buildings with a score of 75 or better are top performers and may be eligible for the ENERGY STAR® certification. Some building types are currently not eligible to receive an ENERGY STAR® score, but can still benefit from benchmarking, as Portfolio Manager calculates other energy performance metrics such as EUI.
No, per Ordinance No. 05 - Building IQ, property owners must use ENERGY STAR® Portfolio Manager to benchmark and report their covered buildings to the City of Aspen. Like many other jurisdictions across the nation, Aspen is using the reporting functionality of Portfolio Manager to ensure compliance with Building IQ.
