DESIGNING FOR ZERO CARBON EPILOGUE
Epilogue
Additional Exemplary All-Electric Low-Energy Buildings
The projects shown on these pages are recently-completed buildings, both new and renovated structures, that were designed with all-electric energy systems. These are noteworthy for their energy-efficient design, leading in most cases to an expected zero-net-energy (ZNE) perfor- mance when measured over the next few years. Some feature battery storage systems for load shifting to off-peak times and for added resiliency. Two of the projects (Sonoma Academy and SFUSD Central Kitchen) have large kitchens utilizing the latest all-electric cooking appliances.
These projects are listed here to provide the reader with additional resources to study all-electric buildings of all types.
The projects shown on these pages demonstrate the range in size and complexity of all building types that can be all-electric for both public and private clients.
