2025 Greenbuild Campbell Tour: Award Winning Living Building
The 2025 Greenbuild Project Tours featured GAIA’s Campbell Collective, a Zero Energy Certified home by Living Future and winner of multiple USGBC-CA Sustainable Innovation Awards.
This regenerative retrofit demonstrated true net-positive living through solar-powered energy and water generation, rainwater harvesting, upcycled materials, and on-site food production.
Attendees explored how a 1947 Los Angeles residence was transformed to achieve Living Building Challenge petals for Place, Beauty, and Health & Happiness. The project team shared insights on Red List-free materials, permaculture-based design, and resilience planning for off-grid independence.
