Bold Ideas Build Brighter Futures
The Orange County Sustainability Decathlon challenges university teams to design and build model solar-powered homes that address climate change and California’s housing needs. OCSD teams will showcase innovative, market-ready model homes to display in a sustainable village which will be open to the public.
Attend the Event
The Orange County Sustainability Decathlon will take place October 5-15, 2023, at the OC Fair & Event Center in Costa Mesa, CA. The event will feature the OCSD competition, as well as a STEAM Student Showcase that is open to both high school and college teams.
Team Support From California
State Senator Dave Min championed a significant grant from the California Legislature to make the Orange County Sustainability Decathlon a reality. Thanks to this funding, 14 teams were selected to participate in this new competition. Each received seed money for their project.
Sponsor the OCSD
The impact of climate change is increasingly evident. Wildfires, droughts, rising sea levels, and shifting weather patterns threaten our environment and our way of life. We need innovative solutions that will accelerate resilient, sustainable living.
