Past work resulted in a common zero-energy building (ZEB) definition system of "zero energy" and a classification system for ZEBs based on the renewable energy sources used by a building. A definition for a zero-energy community is different and more complex than that of a ZEB because a community uses energy not only for buildings but also for industry, vehicles, and community-based infrastructure. This paper begins with a focus solely on buildings and expands the concept to define a zero-energy community (ZEC), applying the ZEB hierarchical renewable classification system to the concept of community. This approach emphasizes using all possible cost-effective energy-efficiency and demand-avoidance strategies first and then using renewable energy sources and technologies that are located in three places: first, on space within the built environment or unusable brownfield sites within the community; second, on either green space within the community or located outside the community boundary but within the region and brought into the community; and third, through the purchase of new Renewable Energy Certificates (RECs).
