The Zero Net Energy Roadmap is a study that determined the technical, financial, and organizational feasibility of achieving Zero Net Energy (ZNE) for over 100 municipal facilities. The project was funded primarily by a California Energy Commission (CEC) Local Government Challenge grant. An actionable roadmap, building energy report cards, and an implementation tool were developed through a detailed technical analysis supported by comprehensive building energy benchmarking and audits, energy simulation analysis, and a cost-effectiveness analysis of measures.
