Vehicle emissions test facility and headquarters

California Air Resources Board

The most advanced vehicle testing in the world, in the largest zero net energy lab building in the US.

The California Air Resources Board (CARB) promotes and protects public health, welfare, and ecological resources through effective reduction of air pollutants while recognizing and considering effects on the economy. With its new headquarters and vehicle emissions test building, CARB will gather data, conduct analyses, and identify air pollution reduction opportunities in a breakthrough high-performance work environment.

Awarded through design competition to the design-build team of Hensel Phelps, ZGF Architects LLC, and Affiliated Engineers, the flexible CARB building will provide dedicated test cells in an extensive range of capabilities, accommodate evolving test methods, and support development of enhanced on-board diagnostics and portable emissions measurement systems. As a Net Zero Energy Building (NZEB) executed in a context of high loads, precision MEP systems, and setting regulatory standards, the facility expresses deep commitment to sustainability. The project is expected to achieve both LEED Platinum certification and a majority of Tier 2 electives under the CALGreen energy code.

The team used industry and AEI-developed performance modeling tools for rapid system concept testing, validating a suite of climate-responsive systems strategies improving on the project's required energy use intensity (EUI) by an additional 20%. The building's energy use will be offset by 3.8MW of photovoltaic (PV) panels on site. 1.5 MWh of battery storage will optimize utility costs under a net-metering agreement. A comprehensive approach to water conservation, collection, and reuse contributes to a nearly 50% reduction in required potable water use in the dry climate of Riverside.

Consolidating five separate facilities -- including the groundbreaking Haagen-Smit Laboratory -- the new CARB building project will concentrate design into roughly nine months, beginning construction in summer 2018 for completion in early 2021.
