Air Support Operations Center, Ft. Riley recognized

USGBC awards VOA designed facility as a top performing LEED building in Central Plains

Last night, VOA was recognized by the USGBC Central Plains Chapter in Lenexa, Kansas for noteworthy achievements in sustainable design.  VOA has incorporated sustainable design practices in buildings at Fort Riley, Kansas for the past eight years, most recently in 2013 with the completion of the Air Support Operations Center (ASOC). Bradley James, LEED AP and Project Manager attended the USGBC event to accept the award on VOA’s behalf.


The 10th Air Force Air Operations Squadron is responsible for the 1st Army Division’s close air support operations and training worldwide. VOA provided design services for first phase of this project, the 10th ASOS group’s $11.2M LEED Silver complex completed in November of 2010 and located adjacent to the 1st Division Headquarters.

The Air Force developed an advanced new flight simulator for this mission, and the original ASOS buildings were not adequate to house the equipment. In Spring 2012, the government identified a site for a new facility to house the new simulator. The scope included the design of command, administrative and training classrooms used to train air traffic controllers using real life scenarios within a state-of-the-art simulator. This site featured a steep sloped area near a ravine between the original 10th ASOS facility and the 1st Division Headquarters. Site work was a particularly challenging aspect of the project, but through collaboration and communication between owner, contractor and the design team, we achieved an affordable and feasible solution.

Sustainable design efforts on the ASOC led to its LEED Silver certification in 2014. Sustainable designfocused on optimizing energy performance and water efficiency, maintaining a sustainable site including the protection and restoration of the surrounding habitat, and using regional, rapidly renewable and recycled materials. An efficient building envelope was achieved using Low-E insulated glazing to meet the new ASHRAE 189.1 code requirements for U-Factor (insulation) that include the window frame as well as the glazing.

The team developed and implemented new research and detailing for the building construction techniques to enable the building to pass the Army’s new Building Air Tightness test.  It was imperative that the design-build team develop wall sections; details and specifications to meet the laboratory testing standards of ASTM E-2178 for air barrier materials and ASTM 1827 which tests the completed buildings for air leakage. This is typically accomplished with the use of a blower door which pressurizes the building or specific area of the building, thereby allowing for measurement of the air leakage. For this project, the maximum allowable building air leakage rate was 0.25cfm/sf at 75 Pa. as tested according to ASTM E1827 test protocol.  Final test results were well below 0.189 cfm/sf exceeding the requirement by over 30%.



  • Increased energy conservation and efficiency, resulting in attaining 5 points for EA Credit 1: Optimize Energy Performance
  • Increased use of renewable energy resources.
  • Reduction or elimination of toxic and harmful substances in facilities and their surrounding environments, resulting in attaining 1 point each for credits EQ 4.1 thru 4.4
  • Improvements to interior and exterior environments leading to increased productivity and better health.
  • Efficiency in resource and materials utilization, especially water resources, resulting in attaining 2 points for credit WE 3 Water Use Reduction.
  • Selection of materials and products based on their life-cycle environmental impacts.
  • Increased use of materials and products with recycled content, resulting in attaining 2 points for credit MR 4 Recycled Content.
  • Recycling of construction waste and building materials after demolition, resulting in attaining 1 point for MR 2 Construction Waste Management.
  • Reduction in harmful waste products produced during construction.
  • Facility maintenance and operational practices that reduce or eliminate harmful effects on people and the natural environment.


VOA received a favorable performance rating from the U.S. Army Corps of Engineers.  Allan Ewell, USACE Project Manager commented, “The ASOC facility exceeds all of the Air Force’s goals for a building of this type of size. The project was a well-managed, on target design effort.  It was clear that there was an in-depth understanding of sustainability and constructability on the part of the design team which was managed by VOA.”

In 2014, the Air Support Operations Center was awarded an Honor Award by the Design-Build Institute of America’s Mid-America Region for Commercial projects under $10m.
