  • Client/Owner: City of Los Angeles Department of Public Works
  • Architect: Lionakis
  • Contractor: Swinerton Builders
  • Completion Date: 2014

The full-service, outpatient clinic in Lancaster, California, was developed to bring a new, eco-friendly healthcare facility to an area in need of a sustainable revitalization. The building is home to programs designed specifically for the needs of the surrounding community, including the Antelope Valley Hope Center HIV/AIDS Clinic, the regional Foster Care HUB Clinic, the SCAN clinic for children who are suspected victims of sexual or physical abuse, an oncology clinic, and disease management programs for patients with diabetes and asthma.

Tetra Tech’s role in commissioning this project extended from the scoping phase through post-occupancy operations and maintenance review. The design included a curtain wall system that allows natural daylight to lessen energy usage and supports LEED certification. Additionally, heat gain is controlled by a louvre system as part of the architectural design. The entire building complies with Office of Statewide Health Planning and Development-3 requirements within a space promoting physical wellness. The mechanical equipment includes four air handler units and fans on the roof concealed by a perforated mechanical screen with sunshades.

The facility includes a two-story, 121,000-square-foot multi-service ambulatory care center, a 5,500-square-foot craft building, and a 15,630-square-foot material management and central plant building. The project achieved LEED Gold certification.
