The 78,000-square-foot Bronx Library Center at the New York Public Library, the largest public library in the Bronx, is the first publicly funded building in New York City to receive LEED Silver certification. Its open, light interior contrasts the dark 25,000-square-foot building it replaced creating a transparency that connects with the neighborhood. Since its opening in January 2006, numerous community groups began to use the building. If numbers can indicate success, 527,000 items were checked out and 15,400 library cards were issued last year, compared to a previous 154,000 items and 3,100 library cards.

The design of the Bronx Library Center is specific to the site conditions, particularly its eastern orientation and zoning envelope. The sloped metal roof maximizes the building’s area within the zoning constraints and allows light to penetrate the western side of the building. Cantilevered glass on the east façade also gives a sense of openness and maximum light penetration. The design includes an outdoor reading room on the roof that will be surrounded by a 10-foot hedge. Related energy conservation measures include thermally broken glass, light shelves, and mechanical blinds.

In addition to being an important lesson in sustainable design for the client, designers, and contractor, the library enjoys success as a public resource. The users of the building learn about sustainable architecture on a daily basis as they explore the Center’s new design.
