The United States Air Force (USAF) currently utilizes soft-walled shelters to rapidly deploy and set-up bases at remote sites.  These shelters provide a small logistical footprint for both air and surface transport and provide the capability to set-up within minutes, however they are energy inefficient, requiring a constant supply of fuel to generate power for heating and cooling requirements. These shelters are temporary in nature and eventually deployed engineers look for semi-permanent solutions to replace their soft-walled shelters with shelters that improve energy efficiency and quality of life for our deployed Airmen. Information received from this RFI may be used to help identify technical solutions suitable for rapidly enhancing energy-related airbase operation globally.  Information received may ultimately result in requests for equipment manufacturers to demonstrate their technologies at no cost or risk to the USAF as early as the first quarter of Fiscal Year 2018.
