the woman although he claimed he thought she was wearing a hoodie. The security guard, who had been previously terminated by Metropolitan Police for destruction of private property, was not fired despite there being no policy against wearing hoodies in the library. Design The library fills a triangular site and has three stories — one below grade and two above. The entry plaza on the east end of the cite opens to the main lobby that provides access to the lower level which houses community spaces. Peter D. Cook, principal in charge of design at the Davis Brody Bond Aedas architectural firm responsible for the project, explained that “The Library will anchor the neighborhood by providing a civic facility rich in aesthetic, environmental and programmatic assets that is representative of DC Public Library’s commitment to a standard of excellence for all residents.” The defining features of the building is a corrugated, perforated aluminum screen wall system across its southern façade which forms a distinctive jutting prow. With a 40% open area, the screen wall sits three feet in front of an expansive glazed curtain wall and provides shading of the upper level reading room while allowing natural daylight to enter the space. The shading system allows a reduced dependence on artificial lighting and protects the Library’s collection from harmful solar exposure. To take full advantage of the location's potential for unobstructed natural light, clerestory windows and translucent, insulated fiberglass panels on the north provide illumination from the sun on all sides. Lighting design firm MCLA validated light levels in the large, open room through a detailed analysis. The lighting designers developed an electric lighting system based primarily on the T5 linear fluorescent with a 3500-Kelvin color temperature—the lamp preferred by the client for energy and maintenance efficiency. Special fixtures are cantilevered from the tall stacks for vertical illumination on the books, and suspended luminaires are mounted over reading tables and workstations. The renovated building was designed to meet LEED Silver Certification and incorporates a vegetative green roof, displacement air system, solar control and daylight management and uses of recyclable and renewable materials. It received LEED Gold Certification. The design for the new library went through several iterations. At one point, amidst budget constraints, a model was proposed that scrapped much of the glass and proposed a structure similar to the old version. This was driven by the discovery that Metro
