1. Who will be required to benchmark, and by when?

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:

Sector	Property	Properties first notice of upcoming benchmarking due date	Property owners/managers collect property information and utility data	Initial Reporting Date	Calendar year of utility data to report in the first benchmarking year	Date that property benchmarking information is included in annual aggregated community benchmarking report

	Covered Multifamily properties ≥ 20k sq. ft.	January 1, 2023	January 1, 2024 - June 2024	June 1, 2024	2023	September 1, 2024
	Covered Multifamily properties ≥ 15k sq. ft.	January 1, 2024	January 1, 2025 - June 2025	June 1, 2025	2024	September 1, 2025

2. Do single-family, duplex, or triplex residential homes have to comply?

No, none of these residential buildings are required to benchmark under Ordinance No. 05. 

3. What do building owners need to do to benchmark and comply with this ordinance?

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.

4. How do I get my utility bills to enter the data into Portfolio Manager?

For all help with benchmarking, contact CORE.

5. Is my building on the list of commercial properties 20,000 square feet or larger?

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.

6. How much will it cost?

There is no charge to building owners or to the City of Aspen to use the ENERGY STAR®  Portfolio Manager platform to benchmark.

7. How will I and my building benefit from benchmarking?

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.  

8. What is ENERGY STAR® Portfolio Manager?

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. 

9. Can I use another tool besides ENERGY STAR® Portfolio Manager?

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.  

10. I have questions about the ordinance, who do I contact?

Email Climate@aspen.gov and we are happy to help answer your questions.  

11. I am in the process of selling (or have sold) a property that falls under the Building IQ ordinance. What am I required to do?

If a covered property changes ownership, at the time of transfer, the former owner shall furnish to the new owner an electronic copy of the record representing the covered property within the benchmarking tool, utility customer consent documentation, (if any), the request to a qualified utility for aggregated data (if any), and any other information about the property that is necessary for benchmarking the covered property.  

12. What is a Unique Building Identifier (UBID)?

A UBID is a unique way to identify a property, building, or campus of buildings that is more specific than an address, parcel number, or building name. The City of Aspen is using UBIDs to attribute a unique identifier (separate from address or parcel numbers, which can be confusing) to properties under the Building IQ ordinance to ensure utmost clarity in property identification. Each property under the Building IQ ordinance will have a UBID, which the property owner will add to the property’s Portfolio Manager account.
