New Project Profile: California Air Resources Board

$368 Million Southern California Consolidation Project for California Air Resources Board Awarded to Design-Build Team of Hensel Phelps | ZGF | Affiliated Engineers, Inc.

New State-of-the-Art, Zero Net Energy Facilities for Emissions Testing and Research to Open in 2021

RIVERSIDE, Calif., February 7, 2018 – The Department of General Services (DGS) has awarded the new Southern California Consolidation project for the California Air Resources Board (CARB) to the design-build team of Hensel Phelps, ZGF, and Affiliated Engineers, Inc. The $368 million, 380,000-square-foot, 19-acre project will be located in Riverside near the University of California, Riverside campus. The new facility will be one of the largest and most advanced vehicle emissions testing and research facilities in the world. It will also be the largest true zero net energy facility of its type in the world — producing much more energy than it uses.

“Hensel Phelps is excited for the opportunity to partner with both DGS and CARB to help realize this new, one-of-a-kind Southern California facility. It will provide a sustainable, zero net energy home for CARB that enhances the experience of their employees and surrounding community for years to come,” Hensel Phelps Director of Operations, Chris Chacon.

The facility and campus will be designed and built to reach the highest possible levels of measured sustainability, with the intention to achieve LEED Platinum certification from the U.S. Green Building Council and will also meet California’s CALGreen Tier 2 threshold for overall sustainability and energy efficiency.

“Our core values are based on making a difference by enhancing the places people work and live, while creating a more sustainable built environment,” said Ted Hyman, managing partner at ZGF. “It is an honor to work with CARB, an organization that shares our commitment to the environment by improving air quality not only in California but by example, for the entire world.”

The unique design will provide a seamless consolidation and integration of the office program into a three-story, pinwheel-shaped building that will offer vertical connectivity to increase proximity between offices and horizontal connectivity with testing areas, support space, and laboratories, resulting in greater flexibility and interaction. This pinwheel concept creates a Central Command Control area that forms the nexus of the new CARB campus. The high-performance campus will feature abundant open and green spaces, as well as nature walks for al fresco breaks and informal meetings alike.

“CARB leads, the world follows,” stated Affiliated Engineers principal Dave Sereno. “The context of this testing facility is high energy usage and precision measurements. By accepting the challenge of zero net energy for such a building, CARB sets a standard for the world. It is a privilege for Affiliated Engineers to be a part of this project.”

This new facility will consolidate the organization’s five existing locations, currently spread throughout Los Angeles, into a single location that will house more than 400 employees. The state-of-the-art facility will include an extended range of dedicated test cells, especially for testing of heavy-duty vehicles, an advanced chemistry laboratory, workspace for accommodating new test methods for future generations of vehicles, space for developing enhanced onboard diagnostics and portable emissions measurement systems, visitor reception and education areas, a media center, flexible conference areas, and a large public auditorium.

About the California Air Resources Board (CARB)

The California Air Resources Board consists of 16 members. Twelve are appointed by the governor and confirmed by the state Senate. The 12 members include five who serve on local air districts, four experts in fields that shape air quality rules, two public members and one, the chair, who serves as the only full-time member. The other four include two who represent environmental justice communities (one appointed by the Senate and the other by the Assembly) and two nonvoting members appointed for legislative oversight, one each from the Senate and Assembly. CARB's mission is to promote and protect public health, welfare, and ecological resources through effective reduction of air pollutants while recognizing and considering effects on the economy. The CARB oversees all air pollution control efforts in California to attain and maintain health-based air quality standards.
