Denver Buildings

Energy Program

Enrollment in the Energy Program is one compliance option for existing buildings under Denver’s Green Building Ordinance at the time of roof replacement.  

Enroll before it's time for a roof replacement

Why??

  • Choose a "baseline year" from the last five years
  • Get credit for energy-efficient improvements made before it's time for a roof replacement
  • Enrollment is valid for 20 years or through one roof replacement, whichever is longer

Compliance Options in the Energy Program:

  • ENERGY STAR score of 85 or higher
  • 10-15 percent improvement in energy use itensity (EUI) depending on building size
  • Off-site solar
  • LEED Silver
  • On-site solar

The Energy Program sign-up form will be available soon. To receive the form as soon as it becomes available, email EnergizeDenver@denvergov.org.

When a building owner enrolls in the Energy Program they have up to 5 years from the June 1st following their enrollment date to demonstrate they have achieved one of the following 6 options.

  1. ENERGY STAR score of 85 or higher. The score must be maintained annually after initial compliance and will be verified via the building’s annual energy benchmarking report. 
  2. 10% improvement in EUI for 25,000-49,999 square foot buildings.
    —A 5% improvement in EUI is alternately allowed for these buildings if they also purchase off-site solar equivalent to 10% of the energy used in the building from Xcel Energy’s Solar*Rewards Community® or Renewable*Connect programs with a minimum of a 5-year contract.  Contract renewal will be required every 5 years.
  3.  15% improvement in EUI for 50,000+ square foot buildings.
    —A 7.5% improvement in EUI is alternately allowed for these buildings if they also purchase off-site solar equivalent to 15% of the energy used in the building from Xcel Energy’s Solar*Rewards Community® or    Renewable*Connect programs with a minimum of a 5-year contract. Contract renewal will be required every 5 years.
  4. LEED Silver, Enterprise Green Communities certification or equivalent.
  5. Onsite solar in an amount equal to the lesser of the following:
    —5% of the building’s gross floor area
    —42% of the total roof area, or
    —An amount equivalent to 100% of the building’s average annual electricity use.
  6. Off-site solar purchase equivalent to 100% of the electricity used in the building from Xcel Energy’s Solar*Rewards Community® or Renewable*Connect programs with a minimum of a 5-year contract. Contract renewal will be required every 5 years.

For options 2 and 3, the EUI improvement compliance options, the EUI baseline and required savings will be determined based on the building’s annual energy benchmarking report. The required savings must be maintained annually after initial compliance and will be verified via the building’s annual energy benchmarking report.  For buildings with manufacturing use types the owner may apply to use energy consumption per items produced or similar appropriate metric in place of EUI.

  • The building’s default baseline EUI will be the EUI reported in the building’s energy benchmarking report the year prior to enrollment. Alternately, the building owner may select a different calendar year up to 5 years prior to enrollment into the energy program to use as a baseline. 
  • An owner may petition for a change in their baseline if they can demonstrate a major shift in building use type.  An engineer’s report estimating what the new adjusted baseline should be based on the new building use type will be required.
  • If an owner has not yet achieved the required savings in the calendar year prior to the June 1st deadline 5 years after enrollment in the program, then they have the option to instead submit proof of completion of an energy efficiency project.  They must submit report from an energy efficiency contractor showing they have made energy efficiency improvements to the building with an estimated energy savings equal to the required energy savings.  In this case, the benchmarking report submitted 2 years later must demonstrate they have actually achieved the estimated savings. 
  • For owners that submit an energy efficiency project, default baseline EUI will be the EUI reported for the calendar year prior to the completion of the project.  Alternately, the building owner may select a different calendar year up to 5 years prior to completion of the project to use as a baseline.   For example, any building submitted improvements in 2018 may select a baseline year as far back as 2013; any building submitting improvements in 2023 may select a baseline year as far back as 2018
