Department of Energy Report

Buildings 2

On November 2, 2015, the Osage Nation celebrated opening two state-of-the-art tribal government buildings designed with energy efficiency, comfort, and cost savings in mind. The buildings incorporate daylighting, energy-efficient windows, geothermal heat pumps, fans, and other environmentally friendly design features that optimize the use of natural light, moderate heating, and cooling and reduce electricity consumption and costs. In addition to providing a healthier, more comfortable workspace for occupants and an inviting atmosphere for visitors, the two new buildings boast greater combined energy performance than some individual tribal buildings of an older design, according to the Tribal Development. The first building is slightly smaller than the two and is occupied by mostly nonservice-based departments. The larger 20,000-square-foot Welcome Center, or O-KIKI-E TSI in the Osage language, houses mostly service programs. Both structures are elegant, inviting, and highly energy efficient.

An Office of Constituent Services office helps people navigate Osage Nation programs and departments. The tribe actively explores project development opportunities and innovative technology options to optimize energy use and lower tribal operating costs. In an effort to better understand the process for developing and financing renewable energy projects, several tribal government staff members attended one of the U.S. Department of Energy Office of Indian Energy’s regional workshops, which are offered throughout the year and are free for tribal leaders and staff.

Since 2015 Tribal Development has been tackling the challenges of operating this unique system. 

Successes include: 

Robert Gibson
Osage Nation Stationary Engineer Robert Gibson
  • Tribal Development hired a Stationary Engineer (SE) on July 4, 2022.
  • SE has completed major equipment and repair maintenance to restore the system to efficient operation. 
  • The system now operates close to design; however, more improvements are needed. 
  • The system currently runs at 79.5 Energy Use Index. 


Energy Use Index (EUI) is the most common means of expressing the total energy consumption for a building and provides information similar to the "average gas mileage" of your car. EUI expresses a building’s energy use as a function of its size or other characteristics.
