Aurora is Colorado’s third-largest city by population, and its commercial real estate market is more diverse than most people outside the Denver metro give it credit for. The Anschutz Medical Campus on the western edge of Aurora is one of the highest-concentration clusters of large covered buildings in the entire state. The DIA Business Corridor north of I-70 contains millions of square feet of industrial, logistics, and flex-office space. And the Fitzsimons redevelopment zone continues to add major healthcare and research buildings above the Regulation 28 threshold every year.
For Aurora building owners, the December 2026 and 2027 compliance deadlines aren’t distant. Anschutz-adjacent properties and DIA Corridor industrial buildings over 100,000 sq ft are 18 months or less from the first performance deadline.

The Anschutz Medical Campus: Aurora’s Highest-Stakes Compliance Zone
The UCHealth University of Colorado Hospital, Children’s Hospital Colorado, the CU Anschutz medical school complex, and the Veterans Affairs Medical Center together make up one of the densest clusters of large covered buildings in Colorado. Buildings here commonly exceed 200,000 sq ft, placing them firmly in the December 31, 2026 compliance deadline group.
Healthcare buildings at Anschutz present a specific audit challenge: their EUI profiles are driven by 24/7 operations, sterile environments, and sophisticated medical equipment — factors that push energy intensity well above the prescribed targets for general commercial use. Most Anschutz-area facilities we’ve evaluated are better served by Pathway 3 or 4 (GHG intensity or GHG reduction) rather than the EUI-based pathways, particularly as Xcel Energy’s grid continues to decarbonize.
DIA Business Corridor: Industrial and Logistics at Scale
The Tower Road corridor north and northeast of Denver International Airport contains some of Colorado’s largest industrial properties. Amazon’s 1 million sq ft fulfillment center near E-470, multiple FedEx and UPS distribution facilities, and hundreds of thousands of square feet of light industrial and flex space along Tower Road all fall within Aurora’s city limits and under Regulation 28.
For large logistics and distribution facilities, the EUI picture is often better than it looks. These buildings run forklifts, conveyor systems, and lighting, but relatively limited HVAC compared to office or healthcare. Many will qualify for Pathway 1 (prescribed EUI target) without additional capital investment. An audit confirms this.
The I-225 Corridor: Office and Mixed-Use
The I-225 corridor running through central Aurora — from the Alameda/Peoria intersection up to E. Colfax — holds the city’s densest concentration of private commercial office buildings. Properties here range from the Aurora City Center complex to office parks serving the Anschutz workforce and regional service companies.
These buildings are predominantly mid-1990s to mid-2000s vintage, meaning their mechanical systems are at or past typical replacement age. For building owners planning HVAC replacements in the next 2–3 years anyway, timing the replacement to align with an audit-supported ECM plan allows them to claim Xcel Energy incentives and satisfy the compliance requirement simultaneously.
Aurora Multifamily: Regulation 28’s Overlooked Category
Aurora has one of the highest concentrations of large multifamily developments in the Denver metro — driven by affordability compared to Denver proper and proximity to Anschutz, the airport, and the I-225 employment corridor. Apartment complexes above 50,000 sq ft (roughly 70+ units in a standard development) are covered by Regulation 28, and many Aurora multifamily owners we’ve spoken with are surprised to learn this.
Multifamily buildings tend to have moderate EUI profiles but face different ECM opportunities than office or healthcare — heat pump water heater conversions, common area LED upgrades, building envelope air sealing — and the Xcel Energy residential-adjacent commercial rebate programs apply.

Aurora Compliance: What Building Owners Should Do Now
If you own a building on the Anschutz campus or in the DIA Corridor and it exceeds 100,000 sq ft, you’re fewer than 18 months from your performance deadline. Audit timelines run 6–10 weeks. Factor in time to implement at least preliminary ECMs before the deadline if you’re targeting Pathway 2 or 4.
For 50,000–99,999 sq ft buildings, the December 31, 2027 deadline gives more margin — but not unlimited margin.
