Symposium on the Changing Face of ZNE and Responsible Grid Citizenship: October 17, 2018

California is one step closer to implementing the 2019 Title-24 Energy Standards, a formula for Zero Net Energy (ZNE) for residential buildings and more stringency for non-residential buildings on the path to 2030. The implementation path for ZNE, the metrics used, and the discussion around impacts to the utility infrastructure have all evolved quickly. 

At this event a group of exceptional speakers will present updates to California’s building energy efficiency standards for ZNE and compare that with the California ZERO Code from Architecture 2030 and other references. The session will include discussion of electrification as a path to achieve carbon reductions in buildings, and how this will impact the grid in terms of energy storage and grid harmonization. Participants will discuss paths to decarbonize existing electric systems, such as community scale solar and community choice aggregation. The session will conclude with a panel discussion to allow for dialogue and audience participation.
