the roof's undulations. The system is
slightly angled, which makes it appear to
be curved when seen from far above.
Sollega said the radius design of the array
" demonstrates the flexibility of the FR510's
capabilities, " and said the system " will generate
over 2.2 MWh a year of electricity. "
" It's a high-profile project. It was a LEED
certification building, and being involved in
a LEED project is exciting, " said Elie Rothschild,
sales manager for Sollega. " We're a
San Francisco-based company, so it's great
to be involved at the airport. "
Rothschild
told POWER:
" It was a
challenging roof, because it's a C-shaped
building. We had to adapt the arrays to
suit the roof. There are pretty significant
undulations on the roof, and our racking
handles undulations pretty well. We've
done a few airports now, so we've gotten
experience with that. " Rothschild said
Sollega already is preparing to work on
the next phase of the Terminal 1 expansion
project. The company a few years
ago installed rooftop solar systems at
the Honolulu International and Kahului
airports in Hawaii.
Energy-Efficient Systems
Harvey Milk 1 features a tote-based Independent
Carrier System, or ICS, to manage
checked baggage. It's the first such
system in the U.S.; officials said it uses
50% less energy, and is easier to operate
and maintain, than previous baggage
systems. The terminal also uses " selfenergizing, "
or regenerative, elevators
that recycle energy, rather than discarding
it as heat. The site's " Go-Slow " escalators
and moving walkways reduce their
speed when not in use, another energysaving
feature.
Radiant heating and cooling complement
the terminal's displacement ventilation,
another energy-efficient feature that
also improves the indoor air quality. Controllable,
dimmable, long-life LED fixtures
throughout the facility also save energy.
Other features of the project include:
■ Dynamic glazed windows that change
with the sun's location to reduce glare
and improve comfort.
■ Large windows harnessing daylight to
reduce the need for electric lighting.
■ Low-flow, hands-free bathroom fixtures
and faucets save water in
drought-prone California.
■ Highly efficient outdoor air filtration
system to remove pollutants and odor
to provide healthier indoor environments
with minimal efficiency impacts.
■ Building materials and furnishings

with low-volatile organic compound
(VOC) emissions.
■ Selection of products, systems, and
materials with the least environmental
impact.
■ An integrated building management
system measures energy and water
use and adjusts equipment to be
more efficient.
■ Seamless access to all facilities, including
public transit, via the AirTrain electric
people mover, which eliminated more
than 600,000 miles of bus trips annually.
■ Recycling and diversion of about 95%
of construction waste from landfill.
Installations in the terminal include
several educational displays about the
life of Milk, who was assassinated after
serving 11 months on the San Francisco
Board of Supervisors in 1978. Corridors
leading to the customs areas include a
photo essay about Milk. " I think people
in the Bay Area are probably familiar
with him, whereas people coming from
abroad have maybe never even heard of
him, " said Doug Yakel, an SFO spokesperson.
" This really helps tell the story
to a more international audience. "
Environmental and Sustainability
Focus
HKS, an airport design firm; Woods
Bagot, a global architectural practice;
ED2, a technology company; and KYA, a
group that creates sustainable built environments,
were all part of the project's
design-built team. HKS served as the
project lead for programming and exterior
envelope architecture, as well as the
sustainability lead partnered with Arup.
Arup, a multinational professional services
company that provides design,
engineering,
architecture,
planning, and
advisory services, " worked with the multidisciplinary
design team to make sure
everything from structural materials to
floor finishes to unique systems met rigorous
sustainability criteria, " according to the
company. Arup said, " By optimizing the
cement content of the structural concrete,
we were able to reduce the embodied carbon
footprint of the entire building by over
10%. " The company also said, " In a first
for the building industry, we are obtaining
an environmental product declaration for
the passenger boarding bridges-a critical
piece of information that allows for the assessment
and improvement of the environmental
footprint of building components. "
That environmental focus aligns with
the airport's " Sustainability Strategy, "
which emphasizes zero waste, carbon

Winning Attributes
✔ Terminal 1 features an innovative
racking system and roof-mounted
solar array that provides renewable
energy for the facility.

neutrality through electrification, and a
" zero net energy " campus.
Satero told POWER, " This facility was
designed with both our passengers and
employees in mind ... as a place to be relaxed,
a place to be healthy, and a place
to be inspired by the legacy of pioneering
civil rights leader Harvey Milk. This terminal
embodies the very best values of the
San Francisco Bay Area, and we are proud
that this is the first airport facility ever to
be certified under the Fitwel standards. "
Fitwel is a building rating parameter
for commercial buildings, and for both
single-tenant and multi-tenant existing
structures, that offer best practices and
guidelines in designing and operating
healthier buildings. They are established
as a collaborative initiative coordinated
by the U.S. Centers for Disease Control
and Prevention in conjunction with the
General Services Administration.
The USGBC, meanwhile, said the LEED
v4 certification " is designed to up the ante
with a more flexible, performance-based
approach that calls for measurable results
throughout a building's life cycle. " Said
Satero: " We are truly proud to be the first
airport in the world to earn LEED v4 Platinum
certification. This achievement continues
a tradition of leadership in sustainable
facilities that includes the first LEED Gold
airport terminal in the United States, and
the world's first zero net energy facility at
an airport. My thanks go out to the entire
project team for continuing to push the envelope
for what airports can accomplish to
support our environmental goals. " ■
