Yuma County Energy Audit:Report Summary
General Services DepartmentAugust 16, 2010
Project # 910-GS0006
Triple Bottom Line
• Americans saved enough energy in 2009 alone to avoid greenhouse gas emissions equivalent to those from 30 million cars — all while saving nearly $17 billion on their utility bills.
• 1979 - 28% of all our oil is imported• Today +60% is imported• Consumption over this period quintupled

• EEM #1 Lighting Retrofits– Replace older fluorescent lamps with energy efficient
longer lasting lamps – Add occupancy sensors where practical
• EEM #2 Adjust Temperature Controls– Change temperature set-points to industry standards
(no lower than 76⁰F for cooling, no higher than 74⁰F for heating)
– Program HVAC units to allow the Cooling & Heating systems to turn off/down during unoccupied period
Summary of Energy Conservation Measures (EEMs)
Summary of Energy Conservation Measures (EEMs)
• EEM #3 Exterior Lighting Retrofits– Replace HID/Metal Halide lamps with more energy
efficient fluorescent lamps• EEM #4 Window Replacement– Replace single pane windows with dual pane
• EEM #5 Demand Control Ventilation– Decrease/increase outside air into the building based
upon fresh air demand
Summary of Energy Conservation Measures (EEMs)
• EEM #6 PC Power Management/Server Consolidation– Turns computers off when not in use– Consolidation of servers or “Clouding” can create
savings• EEM # 7 Variable Frequency Drives On Motors– Allows motors to operate at reduced power levels,
matching the demand
Summary of Energy Conservation Measures (EEMs)
• EEM #8 Replace Aging AC units– Air Conditioning units older than 15 years should be
replaced with energy efficient units• EEM #9 Install More Energy Efficient Vending Mizers– Compressors and lights are activated by motion sensors
• EEM #10 Solar Power– Install Photovoltaic panels to reduce consumption
