To comply with the Energize Denver Performance Requirements, buildings meet their energy efficiency target by the deadline. Buildings show the city that they have met their target when they submit their annual benchmarking report. Benchmarking reports show the previous calendar year's energy use. For example, you would prove that you have met your 2032 target when you submit benchmarking data in 2033. The data you will send us will be from January 1, 2032 to December 31, 2032.
Every building will demonstrate progress at an interim energy efficiency target. You can look up your building's details in the Performance Requirements Look Up Tool.
As the ordinance was written, all buildings had an interim energy efficiency target in 2024, another in 2026, and a final target in 2030. We then offered an automatic Timeline Extension to all buildings who had completed their 2021 benchmarking report. This Timeline Extension moved the first interim compliance year from 2024 to 2025.
During the 2025 benchmarking season, all buildings will have the opportunity to opt into an updated timeline when they submit their benchmarking report. This new timeline:
- Shifts your first interim target year to 2028
- Eliminates your second interim target year
- Shifts your final target year from 2030 to 2032
Each building's energy efficiency targets are unique to that building and based on how you report the building's various uses. We assign your 2032 target based on how much of the building is used for different functions. For example, if your building has both commercial office space and restaurant space, you will have a blended target based on the percentage of gross floor area assigned to each building type.
The targets we used to create your building's unique final energy efficiency target are below. You can also find them in Appendix A in the Technical Guidance.

Performance Evaluation refers to the times when the city verifies that you have met either your interim or final energy efficiency goal. This process begins on June 1 of the year following the measurement year. We will be looking at your energy use data from January 1 through December 31 of the measurement year (the year when the target was due). For example, we will go through the Performance Evaluation process starting on June 1, 2029, to review your data from 2028 and verify that you met your interim energy efficiency target.
The Performance Evaluation process includes:
If the building’s current site EUI (the way we measure energy efficiency) is higher than the target, the building is not in compliance with that year’s energy efficiency target. See Section 8 of the Technical Guidance for more information on this process.
We will notify building owners of compliance status by an email from EnergizeDenver@denvergov.org. If we do not have an email on file, we will mail a physical letter to the building’s main address.
There are multiple opportunities to avoid penalties in this program:
Corrective Action Process
When you receive an energy audit, the audit report will include a list of estimated energy efficiency gains. However, these estimates may vary from actual energy efficiency gains when you actually implement building improvements. Many factors can influence this final outcome, including:
- The specific equipment selected during the bidding process
- Installation quality
- Proper commissioning procedures
- Ongoing operation and maintenance practices
- Occupant behavior patterns
To account for this, we developed a corrective action process to allow you to make adjustments to your building instead of being assessed penalties.
- If the building is 5% or less away from the target, you can file a corrective action plan following the instructions in Section 9.2.4 of Technical Guidance.
- If the building is 6% or more away from the target, a more comprehensive response is required.
- You will need to complete a new energy audit and compliance plan
- You will submit these new items using the Timeline Extension process (described in Section 7.2 of the Technical Guidance)
Performance Requirements Enforcement Steps
- Warning Notice: Once we determine that a building is not in compliance, we will send a warning notice to the building owner. The owner will have ninety (90) days from the date of the warning notice to apply for:
- A corrective action plan if you are within 5% of your target and can make adjustments to your building within one year
- A timeline extension if a long-term plan is needed
- Notice of Violation: If the building owner has not applied for a timeline extension or corrective action plan by the end of the 90 days, we will issue a notice of violation. The building owner will have thirty (30) days to file an appeal of the notice of violation.
- Civil Penalty – Administrative Citation: If the building owner has not filed an appeal, an administrative citation is issued. The building owner has one hundred eighty (180) days from the administrative citation date to pay the penalty with the manager of finance.
-
Property Lien: If a building owner fails to pay the required amount within one hundred eighty (180) days, the civil penalty will be considered a debt to the city until paid in full. The debt is a perpetual lien on the property until the civil penalty owed, delinquent interest, and recording fees have been paid in full.
Performance Evaluation and Enforcement Timeline
Appeals
A building owner has the right to appeal an administrative citation or decision by filing a “petition for appeal.” See Section 10 of the Technical Guidance for the appeals processes based on the type of appeal you wish to request.
See Energize Denver Forms
The city’s goal is to work alongside Denver’s building owners, property managers, and service providers to make reducing energy use practical, more affordable, and better aligned with each unique building. We’ve increased the options available to buildings to help put compliance within reach. This ranges from adjusting energy efficiency targets and compliance deadlines to developing customized plans for phased improvements.
Our commitment is to work with your building, support you with your efforts, and explore adjustments and extensions to the fullest extent possible so that penalties are not assessed.
There are multiple opportunities to avoid penalties with this program. If penalties are assessed, the penalty structure below will be assessed. See Section 9.2 of Technical Guidance for more information.
Types of Penalties
There are two main types of penalties:
- Target Penalties: Occur if the building does not reach the Interim Target, Final Target
- Maintenance Penalties: Occur after the building reaches their final target if you do not maintain your Final Target indefinitely. If your annual site EUI is 5% worse than the target you are supposed to be maintaining, we will switch you back to the target penalty level until you achieve the target again.
Penalties are assessed by first determining the “kBtu not achieved,” which is the difference between your energy efficiency goal and your actual energy use. You can see how this is calculated in the Performance Evaluation section of the Technical Guidance. We then multiply that value it by the penalty rate. The resulting total is the the penalty amount.

How did Denver Determine the 2030 Targets?
Denver has set a goal for existing buildings to reach net zero energy by 2040. The Energize Denver Task Force used that goal as a starting place to set the 2030 targets.
Targets were set by building type (e.g. an office vs. a hotel vs. a restaurant) to account for the different amounts of energy they use. To determine the final EUI targets, the city used ENERGY STAR® Portfolio Manager® building types from the annual benchmarking submissions. From there, we determined the target EUI for each building type needed to reach the city’s goals.
For a more in-depth explanation of our methods, review the Building Typology and EUI Targets methodology.
How did Denver Determine the Baseline and Interim Targets?
The baseline EUI, along with the 2024/2025 and 2027 interim target EUIs, is unique to each building.
We set each building’s baseline EUI based on the 2019 benchmarking data submitted to the city. Determining the interim targets for 2024 and 2027 was simple. We drew a straight line from a building’s 2019 baseline EUI to their 2030 EUI target. Whatever value the EUI was in 2024/2025 and 2027 became the interim targets for that individual building. This ensures that the EUI reduction between each target is gradual. Buildings must continue to maintain their EUI below their interim targets in following years, and their final EUI for the life of the building.
How do I figure out what my building's targets and deadlines are?
You can use the Performance Requirements Look Up Tool to identify your building’s baseline, interim, and 2030 EUI targets and deadlines. In addition, a letter is sent annually by mail and email as a reminder of your building's targets. And as always, the Help Desk is available to answer questions.
Are new buildings required to comply with the Energize Denver requirements?
Yes, but a new building will not be required to comply until it has been in operation for one full calendar year. That’s when the building shifts from being ”new construction” to an “existing building.”
What if my building was assigned a Denver Building ID and it did not have a certificate of occupancy (or temporary certificate of occupancy) for all twelve months of the calendar year? Please submit an exemption application for that year’s benchmarking requirement.
New buildings under Denver's 2022 Building Code should perform at or below their target EUI. Exactly how it performs depends on the code compliance pathway chosen during design.
When does a new building become an existing building that must start benchmarking?
After the building is constructed and has been in operation for 12 months in one calendar year. For example, a building that received its certificate of occupancy in June 2022 would become an existing building in the 2023 calendar year. It would have to submit its first benchmarking report for the 2023 calendar year (January 1, 2023 to December 31, 2023) to our office by June 1, 2024. The building will then be assigned 2030 performance targets.
My building is new. What is my baseline EUI?
If the EUI performance of a new building is higher than the 2030 target for its building type, the baseline can be the predicted EUI that was submitted as part of energy code compliance. If there is no predicted EUI, the city will establish a reasonable baseline based on the building type. If the EUI performance of the building is below the 2030 target, all the building has to do is maintain their performance.
How do the building performance requirements affect organizations that have multiple buildings in a campus setting?
For campuses, every qualifying building must reach compliance individually. The exception happens when all the buildings are on a single meter and cannot be separated. It all depends on how the campus buildings must benchmark based on their utility meter configuration.
Breaking down the high-intensity building types on a campus is critical to setting the correct 2030 target. A campus option is available for submitting an application for a timeline adjustment. We will work with the campus to apply for renewable credits.
How does Energize Denver affect historic buildings?
In most cases, a building’s historic status does not interfere with its ability to meet the energy performance requirements, unless the Landmark Preservation Board has limited the energy efficiency measures the building could perform. An alternate compliance option is available in these circumstances.
How does Energize Denver affect municipal buildings?
The ordinance affects municipal buildings the same as private buildings, so the City and County of Denver is developing detailed plans to bring all qualifying municipal buildings into compliance so that we can lead by example.
My building did not benchmark in 2019. What is my baseline EUI?
For buildings that have never benchmarked, the building type was assigned through research and a 2019 baseline was established by using the median EUI in Denver for that building type. If the building had 2018 or 2020 benchmarking data, one of those years was chosen to be the baseline. If you would like to correct the absence of data so that we can assign a more accurate baseline and interim targets, please reach out to the Help Desk.
Can I change my baseline EUI?
Yes. You can apply for a Target Adjustment to update your building's baseline EUI if:
- Your building’s 2019 benchmarking data was inaccurate
- That year did not reflect normal operations
- You do not have access to data from a previous building owner
Changing your baseline year does not affect your 2030 target! It only changes the trajectory of your interim targets in 2024/2025 and 2027. Before submitting the adjustment request to change your baseline, please reach out to the Building Performance Help Desk at 844-536-4528 or energizedenver@denvergov.org.
What is a Target Adjustment and when should I submit one?
A Target Adjustment is an opportunity to apply standardized adjustments to the building’s EUI target. You can also use it to adjust previous benchmarking to be more reflective of its energy use. Factors that could impact your interim or 2030 targets include:
- High-intensity spaces
- Significant variations in operations
- Building use types
- Square footage
You may want to look into applying for a target adjustment If
- You haven’t benchmarked high-intensity building types
- You have a data center, swimming pool, or parking you couldn’t exclude,
If I had a tenant change, do I need to apply for a Target Adjustment?
Only if the new tenant is at a higher energy use intensity (based on their building use type) than the previous tenant. For example, if the previous tenant is a “office” use and the new tenant is also an “office,” there’s no need for a target adjustment. If you had a retail store that was then converted into a restaurant, you will need a target adjustment. This is to reflect the higher energy use of a restaurant compared to a retail store. Reach out to the Building Performance Help Desk at 844-536-4528 or energizedenver@denvergov.org if you have questions.
