After seven years of planning and fundraising in the midst of a
national recession, construction of the North Carolina chapter of the American
Institute of Architects’ (AIA NC) thoroughly sustainable
Center for Architecture & Design was completed this summer in Raleigh.
Located on an oddly shaped,
previously unused lot in downtown Raleigh near the State Capitol and Government Complex, the new Center is the first
AIA headquarters facility to be built from the ground up expressly for this
purpose, and AIANC hopes it will serve as a flagship for modern, sustainable
urban design in North Carolina’s capital
city.
The three-level, 12,000-square
foot building was designed by noted “green” architect Frank Harmon, FAIA, principal and founder of Frank
Harmon Architect PA, after the firm won a professional competition for the
project in 2008.
Harmon calls the Center “a modern building with a green
heart.” He also says he saw the commission
as his chance to create “an embassy for architecture.”
Quick to note that not a line was
drawn before landscape architect
Gregg Bleam, FASLA, studied the site with him, Harmon stresses that
building and landscape were conceived as “one
interlocking system. The landscape is an extension of the building and the
building is an extension of the landscape.” As if to
underscore that notion, the native stone walls in the landscape extend inside
the building – or extend outside into the landscape, depending on one’s perspective.
The narrow building is sited
snugly up against the existing city sidewalk so that the majority of the
triangular lot is a park-like green space in its urban context. In fact, the
necessary parking area is what Harmon and Bleam call a “parking garden,” porously paved so that it will
dry quickly and can be used for a variety of outdoor functions by AIA NC and
other community groups.
The building’s open floor plan features two main rooms on the ground level and
a continuous open office space on the top floor. The open plan is meant to
evoke a sense of community among occupants, and it also makes temperature and
lighting control more efficient.
Harmon designed the building to
meet LEED Platinum standards as well as AIA Committee On The Environment (COTE)
goals, which include regional appropriateness and the use of regionally
available materials, land use and site ecology, sustainable materials and
methods of construction, reduced water usage, and increased energy efficiency.
The siting, narrow form, and
abundant glazing – including operable windows --
maximize natural ventilation and light in every interior space. (AIA NC
officials report that they rarely turn on interior lights.) Other
sustainability features include:
·
Extensive glazing for natural lighting.
·
Glass or low partition walls so that natural light and ventilation
penetrate through the entire interior.
·
A geothermal heating and cooling system.
·
Rainwater collection for use on site.
·
Porous paving that eliminates stormwater run off.
·
Ninety percent recycled construction waste
·
An energy-efficient Lutron lighting system: There are no switches.
As a room is entered, lights go on in proportion to the light needed depending
on how much natural light is available.
·
Deep overhangs and porches to
shade the building in the summer but allow warming light in the winter.
·
A “green screen” on the
southern elevation: live vines will shade the building in spring and summer.
·
A zinc roof (zinc being one
of the most sustainable metals available)
·
All locally available
materials, including Cypress wood felled by a hurricane in the state’s Great
Dismal Swamp and stone from North Carolina quarries.
·
Low-flow bathroom fixtures.
·
Zero VOC paints and carpets.
·
Operable windows that open for cross-ventilation.
·
All-native landscape plants.
“As we come out of the recession, we won't be building in the same
wasteful ways,” Harmon said. “With new emphasis on alternative energy and sustainable design,
the AIA NC Center shows us a new way to build.”
The building was financed through a Capital Campaign, financing
through the America Recovery and Reinvestment Act, and through in-kind
donations of construction materials.
