GREEN With Great Buildings
By Lorrie Flom
When Dinosaurs in Their World opens to the public
in a few years, it will be Carnegie Museum of Natural History’s
biggest expansion in 100 years—and the first project
in the museum’s history to be built to the exacting
standards of the “green building” rating system
known as LEED, or Leadership in Energy & Environmental
Design. LEED certification is a voluntary program developed
by the U.S. Green Building Council, a national non-profit
organization. Construction projects qualify for different
levels of certification by incorporating sustainable design
principles such as the use of natural lighting and ventilation,
water-reclamation systems, and recycled and nontoxic materials.
“As an institution that researches and teaches the virtues
of biodiversity and environmental conservation, it’s
fitting that our expansion incorporates green-construction
principles,” says
Bill DeWalt, director of Carnegie Museum of Natural History. “It’s
the responsible thing to do, and it will be cost-efficient
in the long run.”
Craig Dunham, associate vice president
of Facilities Planning & Operations
for Carnegie Museums of Pittsburgh, explains that the concepts
of green design and sustainable construction have actually
been around for a long time. But they only recently became
quantifiable thanks to the development of the LEED rating
system. “In
this project, we’re attempting to maximize daylight
and minimize the need for heating and cooling,” says
Dunham. “If
you look back at the evolution of design, for centuries
people have been attempting to do exactly the same thing
through
passive design. In more recent years, there’s been
an explosion in consciousness that has a lot to do with
energy savings,
recycling of building materials, and cost efficiencies.”
Carnegie
Museums is in good company in its quest for LEED certification,
according to Rebecca Flora, executive director
of the Green
Building Alliance, a local non-profit organization that “integrates
environmentally responsible and high-performance design,
construction, and operating practices into the Greater
Pittsburgh market.” In
fact, so many western Pennsylvania organizations have gone “green” with
their new construction or expansion projects, that the
region ranks #1 nationally in the number of environmentally
responsible,
high-performance buildings.
Two stellar examples are the
David L. Lawrence Convention Center (the world’s
first certified green convention center) and PNC Firstside
Center (the largest corporate LEED certified
building in the U.S.). Other notable local projects include
expansions of
the Children’s Museum, Phipps Conservatory, National
Aviary, Heinz History Center, three of Carnegie Library of
Pittsburgh’s recent renovation projects, as well as the
future Children’s Hospital of Pittsburgh. In addition,
the Coro Center for Civic Leadership recently received Gold
LEED certification for its energy efficient commercial interior—the
first such designation in Pennsylvania.
“
All of the new public venues are going in this direction,” says
Flora, “in large part because of the local foundation
community.” She explains that several Pittsburgh foundations,
such as The Heinz Endowments, have provided significant grants
for green construction projects in the region, including the
David L. Lawrence Convention Center and Carnegie Museum’s
Dinosaurs in Their World renovation and expansion project.
A Green History
Pittsburgh’s environmental transformation from smoke-darkened
to green began back in the 1940s, according to Flora. Pittsburgh
has a legacy of responding to environmental issues, she explains—starting
with air and water quality in the ’40s, followed by brownfield
redevelopment in the ’80s, and now the green building
movement, which many local experts attribute to Carnegie Mellon
University Architecture Department’s emphasis on sustainable
or green design.
“
Western Pennsylvania is staking out a claim in green building,” says
Flora. “And in many cases, individual projects are having
an impact in their industry sectors.”
A case in point: PNC’s commitment to green real estate
development—starting with its FirstSide Center and expanding
to all new construction—is being closely watched by such
financial-services leaders as Bank of America. Likewise, Carnegie
Mellon is being watched by other universities after having
completed its LEED-certified New House Residence Hall and committing
to green construction for all future buildings.
“
Right now, Pittsburgh is in the lead, although Seattle
and Portland are close,” says Flora. She notes,
however, that the U.S. remains significantly behind European
countries,
such as Germany, where green building practices are a way
of life—and necessity—due to the shortage
of natural resources.
PNC’s long-term commitment
to building green was the result of an auspicious meeting
between Gary Saulson, director
of Corporate Real Estate for PNC Financial Services Group,
and Rebecca Flora. Saulson recounts that PNC Firstside
was initially conceived as a traditional building—not
green at all. But Saulson became a green convert after
his two-hour
meeting with Flora. He’s since become the board president
of the Green Building Alliance.
“
Rebecca approached me with the idea, and by the time she left
my office, I was building a green building!” explains
Saulson. “If a company can have employees working in
an open, airy environment with natural light and fresh air,
why wouldn’t you do it…as opposed to having them
work in a black box?” Saulson says he can’t think
of any reasons not to build green. “It’s positive
economically, positive for employees, positive for the community,
and positive for our shareholders.”
A Very Good Thing
Since that meeting between Saulson and Flora more than five
years ago, PNC has built a number of green buildings, and
is second only to Ford Motor Company in the number of LEED-certified
buildings. Besides the energy savings, Saulson says that
at Firstside Center, “employee retention is up, absenteeism
is down, and satisfaction is up.”
Tracy Myers, curator
of the Carnegie Museum of Art’s
Heinz Architectural Center, says that building green is no
longer a matter of getting the buy-in of the architectural
world. “These are issues that should concern anyone
who cares about our environment,” Myers says. “The
green projects in Pittsburgh have heightened my conviction
that these projects are of great importance to this region,
and I’m not alone.”
Of all the green buildings
in Pittsburgh, Myers says the new David L. Lawrence Convention
Center stands out with its “swooping
roof that makes a welcoming gesture toward the river.”
Robert
Imperata, executive vice president of the Greater Pittsburgh
Convention and Visitor’s Bureau, says the David L.
Lawrence Convention Center’s LEED certification makes
it easier for his staff to market the facility. “It’s
a very good thing. We do everything in our power to make
people aware
that it’s a green building—and understand the
benefits it provides,” he says. “The building
continues to get rave reviews from people who use it and
from people
who look at it for future use.”
Prehistoric Fossils in a Thoroughly Modern Setting
For 100 years, Carnegie Museum of Natural History’s
renowned dinosaur collection has been housed in Dinosaur
Hall, which was initially built to house one dinosaur.
As the collection grew, the space became increasingly crowded,
with fossils from various periods mingled in completely
unscientific ways. Still, Dinosaur Hall has remained
one of the Museum’s greatest attractions.

Thanks to the expansion
project, which will more than double the current exhibit
space, the Carnegie dinosaurs will finally
have their day in the sun—literally. They’ll
be presented in exciting scenes based on current scientific
understanding,
and housed within a thoroughly modern, light-filled atrium
that soars three stories high. Lead architect Louis Sirianni,
of E. Verner Johnson and Associates, has specialized in
museum design for 25 years. Building a “green” museum
addition was a new twist for him personally, but he says
his firm embraced LEED standards about five years ago.
Sirianni is responsible for developing the overall tone and
look of
the project, while coordinating a team of green building
experts—including
mechanical engineer Paul Petrilli of Pittsburgh’s
Lenz Corporation and architect Bill Pope of locally-based
Burt
Hill Kosar Rittelmann Associates, who has expertise in
LEED certification.
Pope explains that the centerpiece
of the expansion is
the new three-story, 13,000-square-foot Exhibit Atrium,
which
is being built over an existing courtyard. “The brick
and terra cotta exterior finishes of the existing building
are
being utilized as interior finishes,” he says. “By
reusing them and avoiding demolishing the exterior walls,
we earn additional LEED credits.”
Another way Pope
expects to earn credits toward certification is through
innovation credits for educational kiosks that
will be strategically placed throughout the new space.
At the kiosks,
visitors will read about LEED in simple language—and
learn why building green is important for the environment
and the community.
As noted by Director Bill DeWalt, the
decision to go green
was an obvious one for the museum, Dunham says. “As
a natural history museum, we are always careful about choosing
materials and about indoor air quality, because we need
to
protect our collections. We’re introducing daylight
through unique architect-designed ceiling modules, using
extremely
efficient mechanical systems, and using water-based adhesives
and paints that don’t contribute fumes to the indoor
environment.”
He adds that the project will focus
on using materials with high recycled-material content,
as well as wood that
comes
from sustainably harvested “certified forests.” Other
environmentally sound practices include air quality techniques
that reduce the amount of dust entering the air—thus
reducing hazards to employees, visitors, and the collections,
and reducing the amount of dust that remains in the ductwork.
In addition, all construction debris will be carefully
separated and recycled (concrete, steel, etc.), reducing
the amount of
construction waste being shipped to landfills.
Pope notes
that the cost of building green according to LEED specifications
typically adds two to five percent
in up-front
costs. But those costs are usually recouped in long-term
energy savings, in addition to reduced environmental hazards.
And, he says, there’s one other over-riding benefit: “It’s
the right thing to do.”
