Renewable Energy at DEN
Since 2008, DEN has been committed to investing in onsite renewable energy technology.
- Total Acres: over 200
- Production Potential: Nearly 50 megawatts
WAYFINDING: Changes to A-Bridge/ Ansbacher Hall
A-Bridge and Ansbacher Hall will be closed for overnight construction activities from 6 p.m. to 4 a.m., Monday through Thursday nights, through the opening of the East Checkpoint in Q3 2025. During closures, all travelers must use concourse trains to journey to and from the Terminal.

SUSTAINABILITY
Since 2008, DEN has been committed to investing in onsite renewable energy technology.
Denver International Airport’s Jeppesen Terminal was designed to exceed energy conservation standards.
The beautiful and functional fiberglass roof and strategically placed windows allow natural daylight to illuminate the space, significantly reducing the Terminal’s electricity needs during daytime. Other energy conservation measures included high efficiency motors, low-E insulating glass in most windows and a flexible, modular HVAC system design.
More than 20 years later, we continue to build high-performing, energy efficient buildings while working to continually improve our existing facilities.
In 2022, DEN initiated an $83 million EPC to significantly increase the energy efficiency of the existing facility through an upgrade to our Energy Management Controls System, as well as replacement of all remaining non-LED lights. The EPC project will reduce overall energy use by 20% and reduce greenhouse gas emissions by 30,000 metric tons each year.
DEN actively participates in Xcel Energy’s Strategic Energy Management program. This program has already led to energy improvements through proactive resolution of Air Handling Unit issues, operation of DEN’s chilled water plant in “free cooling” mode when conditions are favorable, and by proactively turning off runway complex lights when not in use.
The EPC also has initiated significant water savings, projected to reduce water use by 32%. The water scope was largely completed in 2023 and exceeded projections. Between 2022 and 2023, DEN experienced a 100+ million gallon water use reduction, despite a 13% passenger increase.
DEN continues to partner with Xcel Energy to leverage rebates and incentives that allow us to implement more efficiency projects and maximize our return on investments.
In 2013, DEN deployed the Saab Sensis Aerobahn Surface Management System that provides airport operations managers with real-time information about aircraft deicing operations.
This system improves environmental performance, enhances operational efficiency and reduces ground delays. Although the Aerobahn system is implemented in a handful of U.S. airports, DEN worked with Saab Sensis to integrate the system with our deicing operations.
This Deicing Manager, in tandem with the existing software, allows DEN to manage deicing and snow removal activities more efficiently by optimizing timing and communication, reducing queue times and burning less fuel on the deicing pads and runways. DEN customized the program for its own operations while playing a key role in the development of a Deicing Manager application that could be used at any airport throughout the world.
