The California Green Building Conference 2027, hosted by USGBC California, is the state’s leading sustainability conference focused on green building, climate resilience, and cutting-edge solutions for California’s built environment. More than 1,000 professionals from across industries, including architecture, design, engineering, construction, development, manufacturing, policy, education, and community leadership, come together for a dynamic day of networking, learning, and inspiration.

This year, we're heading to the City of Roses.

There's something about being in a place built for discovery. Caltech in Pasadena has spent more than a century asking big questions and chasing answers that changed the world. Walking its tree-lined paths, with the San Gabriel Mountains watching over campus, you feel it: this is where people come to imagine what's possible.

That's exactly the energy we need right now. The work we do is hard. The challenges in front of California are real. But every year, when this community gathers, we're reminded that we're not doing it alone.

So take the time to step outside between sessions. Share a coffee in the shade with someone you've only ever met on a Zoom call. Have the conversation that sparks your next big project. Find the people who get why this work matters to you.

And when the day winds down, let Pasadena's warm evenings and walkable streets keep the connections going.

Come for the ideas. Stay for the people. Leave reminded why you started.

Who Should Attend?

If you're designing, building, funding, regulating, teaching, or advocating for a more sustainable California, this conference is for you. Whether you're an architect, engineer, developer, product innovator, policymaker, sustainability professional, student, or community leader, you’ll find people here who share your goals, and the tools to help you move them forward.
