Fort Sill Upgrades 1,700 Homes with Geothermal HVAC Systems
Why It Matters
- The Fort Sill project showcases growing adoption of smart HVAC controls. Integrating artificial intelligence-driven predictive maintenance reflects a broader trend toward connected, data-driven building management.
- It also highlights opportunities in energy retrofit projects. Contractors specializing in geothermal systems, controls, and high-efficiency HVAC may find expanding opportunities in military, government, and commercial retrofit markets.
- The Fort Sill project illustrates alternative financing for HVAC upgrades. Energy Savings Performance Contracts provide a model for funding major HVAC modernization projects through future energy savings.
FORT SILL, Oklahoma — Corvias is investing $63 million to modernize more than 1,700 military family homes at Fort Sill, Oklahoma, with geothermal heating and cooling systems, smart thermostats, new hot water systems, and advanced building controls.
According to Corvias, the project is expected to reduce annual energy use across the housing community by 57% while generating more than $5 million in annual energy savings. The upgrades are also intended to improve system reliability, increase resident comfort, and reduce maintenance requirements.
The modernization effort was recently showcased during an event attended by Army leaders, congressional representatives, and industry partners. Corvias said the project demonstrates how government and private-sector collaboration can improve military housing infrastructure while supporting installation resilience.
“As we leverage advanced technologies and partnerships to build a more resilient Fort Sill, it is essential for our collective teams to be synchronized through this process to rapidly deliver the enhanced homes our military families deserve and to generate critical savings that can be reinvested back into Fort Sill and our people,” said U.S. Army Col. John Morgan, Fort Sill garrison commander.
The project is being delivered with support from Velarium Energy and Ameresco. As part of the event, attendees toured ClimateMaster's manufacturing facility in Oklahoma City, where the geothermal heat pumps used in the project are produced, before visiting Fort Sill to observe drilling operations and completed home upgrades.
According to Corvias, the geothermal systems use stable underground temperatures to heat and cool homes, reducing energy consumption by 40% to 70% compared to conventional heating and cooling systems. The upgraded homes also include advanced controls that use artificial intelligence to support predictive maintenance.
The project is being financed through an Energy Savings Performance Contract, which allows infrastructure improvements to be funded through future energy savings rather than upfront capital expenditures.
Corvias said similar Energy Savings Performance Contract projects across its portfolio are projected to generate approximately $61 million in annual savings and more than $1.7 billion over their lifecycle.
