Denver’s Path to Decarbonization: Understanding the Energize Denver Building Performance Policy

Denver isn’t just setting climate goals; it’s enforcing them. To reach its ambitious target of eliminating emissions by 2040, the city has implemented a rigorous framework to tackle one of its largest sources of pollution: buildings. The Energize Denver Building Performance Policy is the cornerstone of this effort, shifting the city from voluntary energy savings to mandatory performance standards.

What is the Energize Denver Building Performance Policy?

Energize Denver is a comprehensive ordinance designed to reduce greenhouse gas emissions by improving the energy efficiency of the city’s building stock. Rather than a one-size-fits-all approach, the policy targets buildings based on their size and impact on the environment. The regulations primarily focus on two categories: buildings between 5,000 and 24,999 square feet and those 25,000 square feet or larger.

The policy operates on a simple but effective logic: you can’t manage what you don’t measure. By requiring building owners to track and report their energy use, the city can identify the least efficient properties and push for targeted improvements.

How the Policy Works: Benchmarking and Performance

The policy relies on two primary mechanisms to ensure buildings are moving toward decarbonization: energy benchmarking and performance standards.

Energy Benchmarking

Benchmarking is the process of tracking a building’s energy and water use. Owners must submit this data to the city, allowing Denver to compare a building’s performance against similar properties. This data-driven approach removes guesswork and highlights exactly where energy is being wasted.

Performance Standards

While benchmarking identifies the problem, performance standards provide the solution. These standards set maximum allowable energy use intensity (EUI) levels. If a building exceeds these limits, the owner must take corrective action—such as upgrading HVAC systems or improving insulation—to bring the building back into compliance.

The Role of Energy Audits in Compliance

For building owners, the jump from a benchmarking report to a fully efficient building can feel overwhelming. This is where energy audits become essential. An audit is a deep dive into a building’s infrastructure to find the “why” behind high energy bills.

Professional audits, such as those following ASHRAE levels, allow owners to prioritize investments. Instead of guessing which upgrades will work, owners can use audit data to implement high-impact measures, including:

• Lighting Upgrades: Replacing outdated fixtures with high-efficiency LED systems.
• Weatherization: Sealing leaks and improving insulation to reduce heating and cooling loads.
• Retro-commissioning: Tuning existing building systems to ensure they operate at peak efficiency.

By linking audits directly to capital planning, the city and private owners can ensure that every dollar spent on upgrades delivers the maximum possible reduction in carbon emissions.

Key Takeaways for Building Owners

• Mandatory Compliance: The policy is not optional for buildings meeting the square footage thresholds.
• Data-First Approach: Benchmarking is the first step; it provides the baseline needed to plan improvements.
• Targeted Upgrades: Energy audits are the most effective way to identify cost-saving and emission-reducing retrofits.
• Long-Term Goal: All these measures align with the City and County of Denver’s broader goal of net-zero emissions by 2040.

Frequently Asked Questions

Which buildings are covered by Energize Denver?

The policy covers commercial and multi-family residential buildings that are 5,000 square feet or larger. The specific requirements vary depending on whether the building is under 25,000 square feet or exceeds that threshold.

What happens if a building is not compliant?

Buildings that fail to meet benchmarking or performance standards may face penalties. The city encourages owners to develop a compliance plan to avoid these penalties and improve their asset’s value.

Are there incentives available for upgrades?

Yes. To help offset the cost of energy-saving improvements, building owners can often access utility rebates and other financial incentives designed to maximize the value of efficiency investments.

Looking Ahead

Denver’s approach to building performance serves as a blueprint for other cities fighting climate change. By combining strict regulation with data-driven auditing, the city is transforming its urban landscape into one that is more sustainable, more affordable to operate, and significantly cleaner. As the 2040 deadline approaches, the transition from fossil fuels to electrified, high-efficiency building systems will only accelerate.
