Beginning with our "Briefing," by Perkins&Will Principal Leigh Christy, FAIA, Season 18 of arcCA DIGEST, "Building Decarbonization," is heavy on resources for practicing architects. Highlighted this season are the Building Decarbonization Practice Guide, developed by the William J. Worthen Foundation; California Building Energy Modeling's Case Study Book Series, authored by Edward Dean, FAIA; Stanford Engineering's Building Decarbonization Learning Accelerator; and a podcast on Energy-Storage Enabled Appliances. Framing these resources is an overview of the regulatory environment by Panama Bartholomy, Founder and Executive Director of the Building Decarbonization Coalition, who also reviews the many benefits of building electrification. In this season's "Angle," Brendon Levitt challenges the prioritization of embodied carbon over operational carbon in building design. An article from AIA San Diego features Net Zero Carbon case studies. And, to provide some recent history, we wrap up with a selection from the arcCA print archive, volume 09.3, "Beyond LEED."
