A net zero-energy community (ZEC) is one that has greatly reduced energy needs through efficiency gains such that the balance of energy for vehicles, thermal, and electrical energy within the community is met by renewable energy. 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. This paper begins with a focus solely on buildings and expands the concept to define a zero-energy community, applying the ZEB hierarchical renewable classification system to the concept of community. A community that offsets all of its energy use from renewables available within the community’s built environment and unusable brownfield sites is at the top of the ZEC classification system at a ZEC of A. (A brownfield site is where the redevelopment or reuse may be complicated by the presence or potential presence of a hazardous substance, pollutant or contaminant.) A community that achieves a ZEC definition primarily through the purchase of new off-site, Renewable Energy Certificates (RECs) is placed at the lowest end of the ZEC classification but is still considered a good achievement.

Designed as a resource for those who want to develop community solar projects, from community organizers or solar energy advocates to government officials or utility managers. By exploring
the range of incentives and policies while providing examples of operational community solar projects, this guide will help communities to plan and implement successful local energy projects. In addition, by highlighting some of the policy best practices, this guide suggests changes in the regulatory landscape that could significantly boost community solar installations across the country.
Encouraging commercial building owners to set measurable energy goals before design begins can drive design and contractor teams to develop innovative energy efficiency solutions within conventional building budgets. The successes and lessons learned by a federal building owner's performance-based procurement project formed the basis of an expanded program using utilities as the outreach channel to replicate the approach. The utilities delivered incentive-based offerings to focus building owners on the whole building rather than on individual building components and systems. This 11-page paper documents the core principles, successes and lessons learned from these utility programs in different areas of the country.
