Imagine a library that continually changes color as you approach and
appears to float above its desert surroundings. After searching for an
appropriate image in which to cast the Appaloosa Branch Library, the
City of Scottsdale's latest addition to its collection of five public
libraries, the architects decided on a mirage theme. Future nearby
buildings are expected to be typical commercial "classical" or
Mediterranean styles, so there was no reason to be directly contextual.
Instead, DWL Architects + Planners and project co-designer Doug Sydnor
Architects and Associates have created a special place with emphasis on
the desert environment. The building rests lightly on the land: activity
rooms cantilever over an arroyo; the Reading Room roof seems to hover
above the 275-foot-long mass wall.
The mass wall, which divides the Reading Room from other activities,
ranges from 16 to 30 feet high. It is composed of three horizontal bands
of exposed aggregate concrete, giving it a geological appearance. This
is the solid anchor around which lighter parts of the building rest. The
tall north wall has continuous glass running along the top and bottom,
with a perforated wall floating between. The short and long windows in
this section are arranged to spell out the library's name in Morse code,
thus preserving the custom of incorporating historic features into
contemporary libraries. The resulting light levels allow the room to
function throughout much of the day without artificial lighting.
The library's metal-clad skin is the first U.S. commercial application
of PPG Industries® Duranar® VARI-Cool iridescent coating. Composed
of mica chips in a clear base, it creates colors through light
interference patterns-like the scales on a hummingbird-to produce colors
ranging from silver to green to mauve, depending on the angle of view.
The finish also reflects infra-red light, and a convective cavity
separates the panels from the building, so heat can rise away from the
wall before it reaches the insulation.
In Central Arizona, library activities can take place outdoors much of
the year. A large shaded patio increases the activity space by providing
tables and chairs for reading, discussions and a venue for
entertainment. Several giant saguaro cacti edge their way into the space
along with a grove of Palo Verde trees.
A wide array of environmental designs and products have earned this
library LEED® (Leadership in Energy and Environmental Design) Gold
certification. Formerly used to accommodate overflow parking for the
Western tourist destination of Rawhide, most of the site has been
restored with native vegetation that includes transplanted cacti and
trees salvaged from the old lot. Building materials were selected to
reduce the heat island effect and to make use of locally produced
products. Oversized ductwork slows down airflow to minimize noise and
energy consumption. A photovoltaic array on the roof sheds part of the
peak energy load, and CO monitors maintain fresh air inside meeting
areas. All together, these factors result in a 32% energy and 53% water
reduction; 93% of the construction waste has been recycled.
