The Hawkeye Aircraft Flight Test and Evaluation Facility serves the needs of the E-2 and C-2 research, development, testing, and evaluation mission.
The facility provides a consolidated infrastructure for more efficient and effective research, development, testing, and evaluation (RDT&E) efforts. The previous facility consisted of several substandard temporary and/or prefabricated buildings. Having exceeded their useful life expectancies these buildings were demolished and recycled as occupants moved to the new facility.
The new building is a multistory, secure facility with structural steel frame, deep pile foundation with grade beams, slab on grade and elevated concrete slab(s), insulated metal wall exterior panel system, and a built-up insulated roof on metal decking on steel joist framing. The building earned LEED Gold certification with a total of 39 points.
The most notable environmental benefits of the project are the efficient use of water and energy in the building. The project incorporates water-conserving plumbing fixtures, including low-flow faucets, showers, and toilet fixtures, to achieve a 54.5% increase in water savings compared to similar facilities. Additionally, potable water use is reduced by 51.5% through the building's wastewater features alone, and no water is used for landscape irrigation. The highly efficient building envelope, consisting of insulated metal panels, windows, and a reflective roofing system is a major contributing factor to the energy savings achieved with the project. There is an estimated energy savings of 39.4% compared to the baseline design, which correlates to an estimated cost savings of 33.2% per year. Efficient mechanical and electrical systems were also used throughout the building to reduce overall electricity consumption.
To ensure the occupants are in a productive environment with low contaminants and good indoor air quality, the air-conditioning system was protected from dust and chemicals during construction. Adhesives, caulks, paints, and flooring were specified to have low levels of volatile organic compounds. Additionally, more than 90% of indoor spaces in the building are designed to have direct line of sight to the outdoor environment.
