Gruen Associates' Senior Associate --Maya White-Turre, AIA --was asked to chair the AIA California (AIA|CA) Embodied Carbon Working Group. The Group forms a critical component of the state organization's climate action activities directing and formulating Zero Net Carbon Design (ZNCD) education opportunities and the AIA's state code advocacy agenda.
The group made several presentations to the California Carbon Reduction Collaborative (CCRC), which consists of members from the California Building & Standards Commission (CBSC), the Department of the State Architect (DSA), and the California Department of Housing & Community Development (HCD). These groups determine updates to CALGreen, the California Building Code (CBC), and the California Residential Code. The Embodied Carbon Working Group was asked to collaborate with the CCRC to refine code, which regulates the embodied carbon of larger buildings and paves the way for reuse of building materials, deconstruction rather than demolition of buildings, and a circular building material economy.
To date, AIA|CA's Embodied Carbon Working Group spearheaded Calgreen's adoption of its first-ever embodied carbon regulations. This year, the Group advocated for expansion of the regulations to cover residential projects over 100,000 SF and moving the threshold of Global Warming Potential (GWP) material thresholds to match California Buy Clean Standards. Maya introduced code language defining salvaged materials and integrating the option to utilize them as having an equivalent GWP of zero. This will likely be included in the 2025 Intervening Supplement to the CBC.
As part of her responsibilities as Chair, Maya is an organizer of and facilitator for Circular SoCal --a symposium on building material reuse, co-sponsored by the AIA|LA and the City of Santa Monica. AIA|CA's ZNCD courses, organized by Maya, include Salvaged Lumber Reuse in Federal Center South, MEP Embodied Carbon 101 for Architects (this September 24th), Biobased Materials & Biogenic Carbon, and Embodied Carbon Software Tools.
