New in 2023. In addition to the 5 hours of learning in disability access, all California architects are now required to receive 5 hours of learning in Zero Net Carbon Design (ZNCD). To help meet these additional mandatory continuing education licensure requirements, AIA California is offering a variety of on-demand ZNCD courses through our partner aecKnowledge. These courses are presented free of charge as part of AIA California’s mission of helping design professionals reduce our carbon footprint. Click here to proceed to these on-demand courses.
