Denver is taking a strong stance on climate action with its ambitious plan to achieve “net zero” carbon emissions by 2040, starting with new building codes for structures larger than 25,000 square feet. The city aims to eliminate the use of natural gas and transition to highly energy-efficient, all-electric buildings powered by renewable energy sources. Failure to comply could result in fines of up to $4.5 million.
The new building codes, adopted in 2021, require these buildings to achieve 30% energy savings by 2030 and switch to electric heating and cooling systems. Denver Mayor Michael B. Hancock believes that these codes are essential in achieving the city’s goal of zero emissions by 2040 and show that climate action is a top priority.
Denver’s Office of Climate Action, Sustainability and Resiliency (CASR) has announced proposed updates to the Energize Denver program, encouraging stakeholder engagement and feedback until December 16th. The city is also planning engagement sessions to discuss rebates and resources for building owners, aiming to provide more flexibility and support.
However, some stakeholders, including commercial and multifamily residential building owners, have filed a lawsuit claiming that the electrification requirements are unconstitutional and preempt federal energy efficiency laws. Denver has filed a motion to dismiss the case, arguing that the plaintiffs have no standing to sue. The decision on the dismissal motion is pending, but Denver remains committed to its electrification goals and achieving a net-zero carbon future.
