“This hangar will set the standard in sustainable design and development for Navy projects and aircraft hangar projects in general,” said Greg Fossett, construction executive at M.A. Mortenson Construction.

 

Hangar 511 is the Navy’s first LEED Silver hangar project and the Navy’s largest LEED Silver project. It is one of only three hangar projects in the world – military or civilian – to achieve a LEED Silver rating.

 

The massive 137,000 square-foot maintenance hangar, more than a million square-foot aircraft apron/taxiway and 140,000 square-foot administrative office building were contracted through the Naval Facilities Engineering Command to house operations for the P-3 Orion and future P-8 Poseidon squadrons responsible for naval reconnaissance.

 

 “As the Navy’s largest active hangar, the facility potentially could have consumed a great deal of energy and had a significant environmental impact,” said Brian Pieplow, HNTB LEED project manager. “Instead, the project team approached the effort from a more holistic and sustainable point of view. We were able to use the LEED Green Building Rating System to design and document a substantial reduction in overall energy and natural resource consumption as well as reduce environmental impacts in comparison with conventional design and construction methods.”

 

Among those energy saving strategies were the installment of six translucent panel systems across the building’s façade to provide natural lighting; sun screening devices to provide shade for the southward facing windows in the administrative spaces; and the use of infra-red heating within hangar space.

 

Other sustainable features that led to a Silver certification rating included the use of pervious paving and grass block paving in the parking areas and ultra light-colored concrete with a high degree of solar reflectance. Both features minimize heat island effects of the aircraft apron parking and taxiways.

 

Hangar 511 cost $128.5 million to complete. Mortenson served as the design-build contractor with HNTB as lead architect and civil engineer. Pace Collaborative served as the mechanical, electrical and plumbing engineer.
