We used a physically-based representative building model in EnergyPlus to quantify changes in energy use due to climate change and heating system electrification. To evaluate the impacts of these changes, we imposed these energy use characteristics on a future electric grid configuration in California using the Holistic Grid Resource Integration and Deployment model.
