Energy Efficiency Conservation Strategy
• Adopted, 2011• Outlined broad-based energy
efficiency and conservation goals
• Identified key goals, objectives, policies, and projects
• Over 80% of listed projects complete; several others underway
5
Energy Efficiency Program Evolution
• County’s energy efficiency program has evolved including:o Energy auditing, benchmarking, measurement and
verification – energy performance savings contracto Research – LED, HVAC automationo Operational best practices – occupancy sensors,
FPL rate plans, low-flow plumbing fixtureso Capital improvements/retrofits
