Since April 2022, the National Western Center in Denver has utilized a sewer heat recovery system to meet 90 percent of the heating and cooling needs for its seven-building campus. This district energy network processes 3,000 gallons of wastewater per minute to provide efficient thermal regulation for over one million square feet of space.
Why it matters
District energy systems offer operators lower maintenance requirements and increased efficiency compared to managing individual building boilers and chillers. By centralizing climate control infrastructure, the campus avoids the capital and operational overhead associated with fragmented HVAC systems across its footprint.
The 3.8-megawatt network processes 3,000 gallons of wastewater per minute across the 250-acre site. This configuration is projected to prevent 2,600 metric tonnes of carbon dioxide emissions annually.
The players
National Western Center
A 250-acre complex in North Denver serving as a hub for agriculture, research, and entertainment facilities.
The details
The facility uses two SHARC 880 units to extract thermal energy from untreated sewage, where temperatures remain between the mid-fifties and mid-seventies degrees Fahrenheit year-round. This energy is transferred to a clean water loop that circulates through a closed-loop network to heat and cool buildings. The design also incorporates built-in capacity to support future campus construction phases.
Timeline
The sewer heat recovery system came online in April 2022.
Market Landscape
This project follows a broader industry trend toward district energy networks as a more efficient alternative to decentralized HVAC systems in large complexes. It marks a departure from traditional standalone utility models by utilizing existing municipal sewer infrastructure for thermal energy recovery.
Operators managing large commercial or mixed-use properties should evaluate if centralizing thermal management through district energy can reduce long-term maintenance spend. Assess whether local wastewater infrastructure density supports similar heat recovery potential for planned campus expansions.
The takeaway
Centralizing utility management via heat recovery is a proven strategy for lowering operational overhead in high-density developments. Owners should track the expansion plans for this site to determine how system capacity scales as new buildings are added to the district energy network.
