Driving Future Change: California Air Resources Board’s Southern California Headquarters Raises the Bar for All-Electric Building Design

With an emphasis on integrated project goals related to operational performance, environmental impact, and occupant experience, CARB’s headquarters campus embodies the highest levels of sustainability and energy efficiency. Designed to meet California ZNE performance criteria, the building has achieved LEED Platinum certification and California Green Building Standards Code (CALGreen) Tier 2 standards.

The project has garnered widespread recognition as the recipient of multiple industry awards and honors, including accolades from Design-Build Institute of America, ENR California, Lab Manager, and more (illustrated further in table below).

Next-Generation Research and Workplace Settings

Spanning roughly 402,000 square feet across 19 acres in Riverside, California, CARB's expanded campus creates a modern platform for advanced research and development (R&D) — accelerating the next generation of sustainable transportation innovation.

All-Electric Laboratory

CARB's signature laboratory enhances the organization's testing capacity and provides the latest technology and equipment for analyzing motor vehicle emissions and their associated impact on the environment and air quality. A new chemistry lab featuring state-of-the-art instrumentation enables researchers to analyze a wide range of motor vehicle emissions data, such as toxicity, reactivity, and climate change impacts.

From dedicated light-, medium-, and heavy-duty vehicle test cells to specialized workspaces for on-board diagnostics and portable emissions systems, the project effectively consolidates previously disparate CARB operations into a centralized R&D hub — optimizing operational performance and overall efficiency.

Modern, Open Office Environment

Organized to optimize adjacencies and visual connectivity between office and R&D functions, the CARB facility boasts a modern, user-centric workplace environment that prioritizes human health and overall occupant experience. The office wing incorporates active chilled beam technology, which provides a flexible and advanced temperature management system proven to decrease noise, drafts, and thermal fluctuations for increased occupant comfort.

Architectural Lighting

Integral to meeting ZNE requirements, the office wing also integrates passive lighting, task lighting, and natural daylighting strategies to significantly optimize energy use and positively impact overall occupant experience. Despite comprising 41 percent of the total program space, this key area uses only 15 percent of the total energy needed for successful building operations.

Decarbonization & Sustainable Design

With a focus on energy efficiency, operational performance, and environmental impact, the Southern California Headquarters campus acts as an extension of the larger CARB mission — to improve air quality and mitigate the impacts of climate change through reduced vehicle emissions.

Its innovative, all-electric, zero-carbon design exceeds California’s Title 24 standards for building energy efficiency by 30 percent and reduces campus energy costs by 75 percent.

In collaboration with the design-build team, the ZNE headquarters campus was planned, designed, and constructed using the highest levels of sustainable building practices with a goal of minimizing climate impact throughout the entire project process — from concept to construction and beyond.

High-Performance Engineered Systems

Through a myriad of energy reduction measures, intelligent solutions, and high-performance engineered systems, the facility reflects an integrated approach to sustainability and decarbonization planning and design — effectively ensuring long-term adaptability, reliability, and resiliency.

• Onsite photovoltaic arrays generate 3.5 MW of renewable solar power/electricity, offsetting building energy use and maximizing overall campus resiliency.
• Climate-responsive systems (developed using proprietary AEI performance modeling tools) improve the building’s energy use intensity by an additional 20 percent.
• Integrated water conservation and collection strategies reduce campus potable water use by nearly 50 percent.
• Active chilled beam technology maximizes usable space (such as the skylights for increased natural daylighting) and uses less air than traditional HVAC systems, reducing the total amount of energy required and overall operating costs.

• Innovative, high-efficiency heating and cooling solutions — including fluid coolers, Aircuity® demand control ventilation, and adiabatic humidification — contribute to a healthy indoor environment while reducing overall energy consumption.
• Occupancy-based fume hood controls in the chemistry lab monitor room activity, adjusting airflow and exhaust as needed to conserve energy during non-use.
• A high-performance facade and building envelope integrating exterior louvers with low-emissivity glazing reduces solar heat gain, enhances natural daylighting, improves indoor ventilation, and reduces overall energy consumption.

A Catalyst for Future Change

The culmination of extensive project planning and interdisciplinary team collaboration, CARB’s Southern Headquarters Campus represents a fundamental shift in how we approach sustainable buildings and laboratory decarbonization.

By creating an advanced, all-electric platform for continued transportation and emissions innovation, CARB has effectively set a new global standard for high-performance design and construction — buildings that drive future change and contribute to healthier, greener communities for all.
