Orange County Sustainability Decathlon 2023 (OCSD23)

The Orange County Sustainability Decathlon is a free event for all ages that will take place October 5-15, 2023, at the OC Fair & Event Center in Costa Mesa, CA. The Opening Ceremony will take place on Thursday, October 5, 2023 from 1:00pm – 3:00 pm.

The event will feature the OCSD competition, which challenges university teams from across the country to design and build model solar-powered homes that address climate change and California’s housing needs. The 14 OCSD teams will showcase innovative, market-ready model homes to display in a sustainable village that will be open to the public. Also featured in the sustainable village, the STEAM Student Showcase will display sustainability-themed support structures and exhibits from both high school and college teams.

Free activities and demonstrations are available for children K-12, including the Child Creative Lab where kids can create robots from recycled materials, the Wyland Mobile Science Lab exhibit about California marine life, and more.

Admission is free but registration is required. Food and beverages are available for purchase in the village and beer gardens. The fairgrounds parking fee is $12 per car. Save and go green by OC Bus, powered by renewable energy and part of OCTA’S commitment to a balanced, equitable, and sustainable transportation network.
