O'Brien360 was part of the design/build team selected by King County for the new Judge Patricia H Clark Children & Family Justice Center, an extensive project to rebuild a large city block and the current justice facilities located on-site. The Judge Patricia H Clark Children & Family Justice Center contains 137,000 sq. ft. of courtrooms, approximately 100 juvenile detention beds, 10,000 sq. ft. of youth program space, and an open space design that reconnects the block to the neighborhood. Reflecting the new King County Green Building Ordinance, the County requires LEEDv4 Gold certification for the project, one of the first LEEDv4 projects for the County. O'Brien360 led the integrative process and sustainable building analysis for the design-build team submission for the competition, including facilitating greenhouse gas mitigation plans, achieving the high-energy targets of the County and LEEDv4, and developing a

pathway to fulfill the materials requirements (related to LEEDv4 and avoiding chemicals of concern). Once selected, we facilitated a large eco-charrette with project stakeholders and tracked and reported progress on sustainability goals and LEED throughout the design. We conducted training on team members' materials requirements, helped research and validate materials selections, and collaborated with the team on LEEDv4 design documentation. The project also earned an innovation credit toward the LEED certification for a green building education plan which included developing digital signage content to be placed throughout the facility and the creation and posting of a project case study.
