This project combines academic research with on-the-ground expertise in an approach that is uniquely positioned to overcome the challenges associated with deploying Advanced Energy Communities (AECs) around existing buildings in disadvantaged communities, and which will generate practical, implementable knowledge. This partnership effort involves unprecedented data analysis and comprehensive community engagement, assesses local obstacles to state code implementation, and lays the groundwork for product and service aggregation at scale. Our focus area will be disadvantaged communities throughout Los Angeles County.
