Central Control System
• Two facilities have an integrated central control system
• System provides a central control point for regulating HVAC temperature after hours
• Plan to connect other campus facilities as they are completed
Public Works Complex
Radiant Floor Heating
• Shop floors have hot water piping that store and emit heat
• Floor heat provides quick recovery after opening shop overhead doors
• Helps melt ice from plow trucks during winter months
Public Works Complex
Radiant Gas Heating
• Radiant gas heat is installed overhead in the main shop
• Considered to be the most energy efficient system for large open shop facilities
Public Works Complex
Pre-heated Intake Air System
• The main shop is equipped with a heated ventilation system
• Pre-heated intake air is supplied when exhaust fans are engaged to reduce energy load on other heating systems
Public Works Complex
Automatic Vehicle Wash System

Large Wind
• Potentially Class 4 winds at the site
• Industrial grade turbine – 2.5 MW
• Provide access to educational partners for programs to teach students how to maintain large wind turbines
Public Works Complex
Small Wind
• Sized to match power consumption at Public Works Complex
• Use technology that can be adapted for small businesses, homes, or farms
Public Works Complex
Solar Electric (Photovoltaic)
• Use PV for targeted applications, such as:
– Street Lighting– Security Systems– Server Rooms
Public Works Complex
Solar Thermal
• Replace gas fired domestic hot water
• Heating and cooling applications
• Supplement radiant floor heating systems
• Supplement vehicle wash system
Public Works Complex
Waste Oil Heating System
• Forced air heat for shop and storage areas in two facilities
• Utilize the 13,000 gallons of oil currently collected each year by HHW
Public Works Complex
Central Control System
• Integrated system for all county facilities
• Centralized automation system
• Monitor renewable energy performance
