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

Green Design

• Good candidate for LEED Certification
• Use of energy efficient systems
• Future use of renewable energy sources
• Energy cost savings are considerable

13
Ground Source Heat Pump

• 44 wells, each 250 feet deep, installed to
  provide ground source heating and cooling.
• Except for pumps, no gas or electricity is needed
  to heat or cool air circulated throughout the
  building

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

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

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

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

27
Automatic Vehicle Wash System
28

• 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

30
Small Wind

• Sized to match power consumption at Public Works
  Complex
• Use technology that can be adapted for small
  businesses, homes, or farms

31
Solar Electric (Photovoltaic)

• Use PV for targeted applications, such as
• Street Lighting
• Security Systems
• Server Rooms

32
Solar Thermal

• Replace gas fired domestic hot water
• Heating and cooling applications
• Supplement radiant floor heating systems
• Supplement vehicle wash system

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

34
Central Control System

• Integrated system for all county facilities
• Centralized automation system
• Monitor renewable energy performance
