Vision for Riley County

“To help save taxpayer dollars by being a leader in the State of Kansas in implementing renewable energy efficient systems at county facilities”

Goals include:- Using energy savings to pay for upgrades- Incorporating renewable energy- Reducing utility costs for operating county facilities

- Providing an educational tool for the community and the state

Current Progress

-Green Design

-Geothermal (Heat Pump)

-Natural Lighting

-High Efficiency Lighting

-Radiant Heating

-Heated Ventilation System

Green Design

• Good candidate for LEED Certification

• Use of energy efficient systems

• Future use of renewable energy sources

• Energy cost savings are considerable

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

Future Options

• Small Wind (50-100kW)

• Large Wind (1-3MW)

• Solar Electric (PV)

• Solar Thermal

• Waste Oil Heating

• Central Control 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
