San Mateo Public Library opened in August 2006. The library and its construction highlights the benefits of adopting green principles, and it has earned a Silver LEED (Leadership in Energy and Environmental Design) certification. Of particular note is the attention paid to the life-cycle of the building’s materials and systems. Some examples include the recycling of 90% of the old building’s demolished materials, new materials obtained from local sustainable sources, increased energy and water efficiency, and consideration for the well being of the occupants through improved indoor air quality. Susan Eschweiler of DES Architects + Engineers, a juror on the selection committee, said, “This is a project that will be nationally, if not internationally, recognized for its sustainable aspects.” The architect was Jennifer Devlin of EHDD Architecture, the builder was Pankow Builder, and the owner is the City of San Mateo.
