Transition to sustainable and healthy building design and construction

Local governments have tremendous influence in shaping the future building stock. Priorities should include energy- and carbon-efficient buildings that also support occupant health and well-being.

CALGreen, California’s Green Building Standards Code, is the nation’s first statewide green building code, setting minimum requirements for sustainable design, construction, and operation. Local jurisdictions can exceed CALGreen and energy code requirements by adopting reach codes to further cut emissions, improve efficiency, and promote healthier indoor environments.

Meeting higher building standards can be complex, especially for property owners and developers with limited re-sources or technical expertise. Clear design guidelines and accessible technical assistance can help bridge this gap, making it easier to understand requirements, reduce costs, and implement effective strategies for energy efficiency, electrification, and indoor air quality. The County will lead the way through investments and improvements to its existing facilities and by demonstrating consistent and forward-looking climate change design standards for new construction. These tools and supports are essential for scaling sustainable building practices countywide.
