A model for corrections with compassion, the Maple Street Correctional Center is an inviting building designed to change the way families and community members interact with those in custody. In designing the facility’s curved glass exterior with views of San Francisco Bay, architects chose mesh to perform multiple duties. Six decorative fins, made from recycled materials, stand off the façade and rest perpendicular to the glass to provide sunshade to open areas. LED lights illuminate the fins at night and contribute to the building’s engaging presence. Adding to the center’s U.S. Building Council LEED Gold certification, round caps at the top of each fin collect rainwater, which then spills over and is channeled to a bioswale garden for natural filtering prior to drainage.
