Replacing 1960s-vintage facilities is in order for the beddown for the Hawaii Air National Guard, with sustainability at the forefront of planning.
Project: Squadron Operations/AMU Hangar
Location: Joint Base Pearl Harbor-Hickam, Hawaii
Client: Hawaii Air National Guard
In recent years the Hawaii Air National Guard (HIANG) transitioned to modern, fifth-generation F-22 Raptor jets for the 19th and 199th Fighter Squadrons. Replacing 1960s-vintage facilities was in order for the beddown, with sustainability at the forefront of planning.
"With Hawaii being what and where it is, there was a desire to make it as cost-effectively sustainable as possible," says Mark Zimmerman, Burns & McDonnell project manager.
Beginning from a blank page and a charrette involving pilots and maintainers who will use the facility, the design and construction have gone even further. The combined squadron operations facility and aircraft maintenance unit hangar has achieved Platinum certification under the U.S. Green Building Council's Leadership in Energy and Environmental Design (LEED) program. "This is for a functional facility constructed within its budget while implementing industry-leading sustainable features," Zimmerman says. "It is the first Air National Guard facility to receive LEED Platinum certification."
The 77,000-square-foot facility includes a six-bay maintenance hangar with adjacent maintenance shops and administrative spaces. The two-story squadron operations portion features daylighting and deep overhangs for shade on the upper level. Between the operations area and hangar, more than 75 percent of occupied spaces have daylight.
Photovoltaic (PV) panels on the roof, in combination with solar panel-covered parking shade structures, offset more than 75 percent of the building's energy. Solar water heating accounts for more than 50 percent of the hot water load. "The high cost of electricity on the island, plus abundant sunshine, made those feasible," says Carrie Bradley, senior sustainability specialist. "PV systems are often too expensive to install and carry an unfavorable payback. In this case, it made sense."
The grounds highlight native Hawaiian landscaping materials. Infiltration basins along the taxiway, using recycled concrete from demolition, cut stormwater runoff almost in half.
Water conservation was also reflected through the use of ultra-low-flow plumbing fixtures, which reduce water use 55 percent compared with typical code-compliant fixtures.
These individual features culminate in a facility that provides exceptional compliance with the government's Energy Policy Act, exceeding the mandated 40 percent savings with help from high-efficiency HVAC systems, controls, a superior building envelope and smart metering.
