This four-bay, air conditioned, mission-critical LEED Gold certified hangar in Italy saves costs while ensuring mission readiness.

Description

This new mission-critical two-story airfield facility features a duo of two-bay hangars capable of fully enclosing four aircraft and is operational 24/7. The design effort included a 76,262 SF concrete apron connecting to Taxiway Foxtrot with aircraft ramps. The bays are divided to control the indoor environment, ensuring that two aircraft always remain in a launch-ready state. The necessity for constant aircraft readiness requires that the hangar bays have full HVAC conditioning and dehumidification, which is not common and increases the facility's energy load. The facility incorporates energy-efficient strategies, including a solar thermal array, an optimized building envelope and efficient MEP systems to reduce energy costs by 23% over ASHRAE standards, saving approximately $144,700 per year. Mission operations are supported with classified storage, protected communications, secure work areas, a SCIF vault, intrusion detection and antiterrorism/force protection (AT/FP) measures.

During design, the aircraft and many of its requirements were classified, limiting the information provided to the design team amid evolving requirements. Site location and orientation were critical to the design solution. Detailed design phasing was implemented to ensure construction would not interfere with existing operations or prohibit runway access for other operational hangars. Prior to construction, demolition and extensive utility system upgrades were required. The RLF team prepared construction documents (CDs) in metric units with translations, and the CDs were certified/compliant with host nation and Italian Mixed Commission requirements. RLF’s work included a life-cycle cost analysis, an architectural comparability study and a U.S.-Italian code study.
