23. 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

24. 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

25. 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

26. 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

27. Automatic Vehicle Wash System Public Works Complex

28. Riley County Public Works Complex Future Options Small Wind (50-100kW) Large Wind (1-3MW) Solar Electric (PV) Solar Thermal Waste Oil Heating Central Control System

29. 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

30. 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

31. Solar Electric (Photovoltaic) Use PV for targeted applications, such as: –Street Lighting –Security Systems –Server Rooms Public Works Complex

32. Solar Thermal Replace gas fired domestic hot water Heating and cooling applications Supplement radiant floor heating systems Supplement vehicle wash system Public Works Complex

33. 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

34. Central Control System Integrated system for all county facilities Centralized automation system Monitor renewable energy performance Public Works Complex
