Civic Center Design Highlights Sustainability
Wave-shaped canopies direct daylight into a city
The 2015 Metal Architecture Design Award judges found the
Newport Beach Civic Center in Newport Beach, Calif., noteworthy for
its elegant, powerful city hall design and sophisticated
sustainable design features.
Steve Chaitow, AIA, LEED BD+C, principal at Bohlin Cywinski
Jackson's San Francisco office, which collaborated with the
architecture firm's Philadelphia office to complete the project,
was project manager for the civic center. Chaitow says
sustainability was integrated into the form and organization of the
city hall building. "The integration allowed us to express the
strength of the building elements themselves," he says. Chaitow
says the civic center design did not include applied materials such
as applied stone, which are sometimes used for municipal buildings.
"We used the skeleton itself and made it interesting," he adds.
Clerestory windows under the wave-shaped roof canopies face
north, which allows light to come into the building and reduce
energy consumption. Additionally, the flat part of the wave shape
was designed to accommodate a future photovoltaic array.
Chaitow says the raised floor in the city hall building allowed
the design to stay within the view-plain limit of the coastal site
and was a more energy-efficient way to deliver clean, cool air to
occupants than a traditional overhead air system.
The 100,000-square-foot city hall has an aluminum-and-glass
curtainwall wrapping around three sides. Large roof overhangs and
sun louvers on the east and west sides of the building provide
sunshading and allow an open façade. A solid skin and trellis were
installed on the south side of the city hall building to reduce
solar heat gain. "The architectural expression was generated
directly from sun control," Chaitow says.
A light color palette was used to maximize the benefits of
natural daylighting, Chaitow says. In addition to the wave-shaped
canopy roofs, the design features other nautical allusions,
including a council chambers clad with Woburn, Mass.-based
RHEINZINK America Inc.'s Flat Lock custom crimped zinc shingles on
the north end of city hall.
St. Petersburg, Fla.-based SEFAR Architecture's TENARA tensile
fabric is stretched over a steel frame, referred to by occupants as
the sail. "A light color palette, nautical allusions, an airy
nature, indoor/ outdoor relationship-these are all things that feel
right for Southern California," he explains.
The $105 million, LEED Gold-certified project includes a
100,000-square-foot city hall, 450-space parking garage,
17,000-square-foot library addition and park situated on a 20-acre
property that runs north and south and is bounded by roadways on
the east and west sides.
Orange, Calif.-based CMF Inc. fabricated and installed
RHEINZINK's Flat Lock custom crimped zinc shingles on the western
exterior of the city hall building. Design Insights Associates
Inc., Los Angeles, fabricated and Bomel Construction, Anaheim
Hills, Calif., installed Raleigh, N.C.-based Umicore Building
Products USA Inc.'s VMZinc's 1-inch formed horizontal zinc wall
panels on the parking garage's elevator shaft. Additionally, CMF
fabricated and installed VMZinc 1-inch formed horizontal zinc
panels on a pedestrian bridge elevator shaft.
