Nearly a decade before green became the new “it” factor in the construction and building operations world, San Diego International Airport (SAN) President/CEO Thella Bowens remarked that sustainability needed to become part of the organization’s DNA.
Today, as this oceanside airport puts the finishing touches on the largest improvement project in its 85-year history, it’s safe to say sustainable DNA flows readily through the facility as it works with nature rather than against it.
The $907 million Green Build, which opened in August, features 10 new gates, a tighter and more efficient security system, a state-of-the-art baggage system, easier airport access and a revamped shopping hub at Terminal 2 West. Largely billed as a means of expanding airport operations, creating jobs and improving the passenger experience, the new construction has at its core an impressive environmentally friendly design that will boost sustainability and cut operations costs throughout its life.
In fact, going green might very well nab this project, four years in the making, the gold—LEED Gold. Bowens points out the airport’s sustainability policy mandates that every facility the airport builds or renovates attain at least a Silver LEED rating from the U.S. Green Building Council (USGBC), she then adds the Green Build project likely exceeded this goal.
“It now looks like we will get at least a Gold rating,” she explains. “But we won’t hear from the USGBC until mid-2014.”
When this recognition comes their way, San Diego will join the elite company of the few airports in the nation holding Gold certification. But as notable as this achievement is, it’s important to note this is not the first time the airport has attained this recognition. Its long-standing sustainability commitment has nabbed LEED Gold for the airport authority’s facilities management building and the airport’s receiving and distribution facility. What’s more, in the near future, the airport will bring on a fixed-based operation facility that is expected to achieve Platinum certification.
All of this is possible because of a sustainability commitment that runs from the top down, says Bryan Enarson, San Diego International Airport vice president of development. “As a public agency we have a responsibility to be good stewards of the environment,” he says. “Doing things where you use recycled materials, lower water usage, and conserve energy all play into improving and helping the environment.”
Easy Being Green
The push to green this airport, situated on 661 acres just two miles northwest of San Diego’s downtown, actually began long before the airport embarked on its latest construction journey, reports Paul Manasjan, environmental affairs director at San Diego County Regional Airport Authority.
“We realized years ago that airports are very much in the public eye and we needed to take a leadership role in reducing our carbon footprint,” he says.
However, simply deciding to become more sustainable wasn’t enough. As Manasjan explains the airport authority needed to first define what it meant for an airport to be sustainable. The resulting definition took the three-legged stool concept of traditional sustainability, where one leg represents environmental responsibility; another, social factors; and the third, economic considerations; and added a fourth leg defined as operational. The resulting acronym, EONS, which stands for Economic Viability, Operational Excellence, Natural Resource Conservation and Social Responsibility, is designed to guide the airport along its sustainable path.
Airport officials then developed strategies to incorporate the EONS concept into their facilities. They joined the San Diego Regional Sustainability Partnership, educated management and senior staff on the need for greater sustainability, then developed a sustainability policy.
This netted a number of firsts for the airport. “In 2008, we became one of the first airports in the nation to have a board-adopted sustainability policy,” Manasjan says. And in 2011, San Diego International Airport became the first major U.S. airport to publish an annual sustainability report as part of the Global Reporting Initiative.
“You can’t manage what you don’t measure,” explains Manasjan. “In order to honor our commitment to continuous improvement in our environmental performance, we had to start measuring and tracking our performance so that internally we could see where we were going, set goals and make adjustments to our methods based on this information.”
These measurements highlight how going green can save some green, he adds. In its 2012 sustainability report, the airport found in areas where energy efficient lighting had been installed, they were able to save 2.3 million kilowatts, enough to power 300 homes for a year; that the installation of low-flow fixtures in restrooms saved approximately 15 gallons of water annually; and that single-stream recycling efforts diverted 677 tons of waste from area landfills.
“We’ve been able to hedge our energy costs, even as we have grown the airport, by putting sustainable efforts in place,” says Enarson. “Sustainability will keep our costs down over the long-term. Remember, 75 percent of a project’s costs are really the long-term costs over the next 30-40 years.”
Transportation officials state the upgrade to Terminal 2 will buy time and ease congestion on the airport’s runway, roadways and security lines. And the project is more than a decade in the making, says Bowens.
“We actually started planning and design before the recession because at that point we were out of gates. We had more airlines coming in than we could accommodate,” Bowens says.
When the Great Recession hit, the playing field changed dramatically, she adds, noting the airport saw dramatic reductions in passenger traffic. Today’s passenger counts have risen to more than 17 million per year, but traffic remains slightly lower than pre-recession levels. The slow-down bought the airport some time to develop a workable design that met future needs and addressed its sustainability goals.
The resulting project features many sustainable highlights, adds Bowens. “Everything from solar panels installed on both the roof and in the parking lot to low-flow fixtures in the building, to the landscaping itself is sustainable,” she says.
Even recycling ramped up during the construction process where 19,000 tons of concrete and asphalt from the old runway apron and former Navy landfill was reused in the new building’s foundation and 75 percent of the construction waste was recycled on-site or sent to an off-site recycling center. Some of this material was even used in the terminal’s new terrazzo flooring.
“It looks like a brand new building, but half of this building actually uses materials we already had,” Bowens says. “We had a plant right at the airport recycling old concrete for the new apron and the building itself.”
The new terminal allows natural light to flow in through floor-to-ceiling windows that utilize reflective glass designed to keep heat or air conditioning inside the building. It also relies on high-efficiency heating and air -conditioning systems and daylight harvesting lights that automatically turn down when natural light is brighter. These changes are expected to reduce energy use by 30 percent, saving nearly 600,000 kilowatt hours of electricity, and putting an estimated $250,000 to the airport’s bottom line.
Solar panels on the building roof, which is coated with white PVC material to reflect the sun’s rays, as well as R-32 insulation in exterior walls, will reduce heat and air-conditioning demand. In fact, the photo-voltaic cells on the roof are expected to generate up to 1 megawatt of electricity at peak use, enough to power 600 homes.
The airport will rack up additional electricity savings with its new baggage system, operated by more than 550 motors, by utilizing motors that are 30 percent more efficient than past systems. Low-emission infrastructure provides power and preconditioned air units for aircraft at the terminal’s gates, which will improve air quality and reduce the airport’s carbon footprint, by eliminating the need for planes to use engines while at the gates.
“Everything we did in this building is designed to enhance or reduce the amount of electricity or water being used,” Bowens says. “We even put in native landscaping to reduce the amount of water use on the outside.”
Put Passengers First
Though sustainable efforts abound, the Green Build primarily focused on positioning the airport for growth and making the passenger experience more pleasurable. And both goals were met, states Bowens.
Sunset Cove, the airport’s new concessions area and one of the project’s more prominent features, provides 9,000 square feet of space for 38 new retail and concessions vendors. “We have actually doubled the size of the airport concessions area, not just in the Green Build section but across the airport,” says Enarson. “This provides opportunities to improve customer service by giving passengers more venues to choose from.”
The airport brought in vendors that dish up some local flavor, including Phil’s BBQ, Stone Brewing Co. and Pannikin Coffee & Tea. A wine bar and an entertainment stage featuring local acts round out the regional flare.
“Travel in and of itself is stressful, and we want to make sure people who use our airport find ways to be diverted from some of that stress,” says Bowens. “And because every airport is unique to its community, we want passengers to identify our airport with the local culture.”
Bowens adds the airport strives to provide passengers with the services, amenities and facilities they truly want and need.
To that end, the completed terminal now offers a new 12-lane security checkpoint (twice the number of lanes as before), 10 new gates (more than double the number they had before) and a 1,200-foot-long, dual-level elevated roadway that separates arriving and departing passengers to alleviate curb-side traffic congestion.
The airport also en- hanced curbside check-ins. These new systems utilize Common Use Passenger Processing Systems (CUPPS) to build flexibility and efficiency into the processing system and give passengers a variety of check-in options. Customers can check in at any kiosk, they do not need to look for an airline-specific one. CUPPS equipment also means that if airlines need to shift from one area to another, they can do so easily.
“By giving customers choices for check in, getting boarding passes, buying a ticket and so on, the lines at ticket counters and gates will be shorter,” says Enarson.
Finally, in honor of San Diego’s large military presence, where nearly 125,000 service members and their families travel through the airport annually, the project included the world’s largest airport USO, which provides amenities such as a children’s area, WiFi access, a lounge, restrooms with showers, and an outside BBQ and patio area. “Members of the military can have their spouses, children and other family members accompany them when departing or returning,” Enarson says.
As one can plainly see, going green and putting passengers first is San Diego International Airport’s mission, making it the new “it” factor in the airport community. And one thing is for certain, neither of these efforts will ever go out of fashion.
