  1. Riley County Public Works Complex IMPLEMENTING SUSTAINABILITY:

  2. Presentation Outline • Introduction to Riley County • Vision for Public Works Complex • Current Progress • Future Options • Project Summary

  3. Introduction to Riley County • Approx. 70,000 residents • County seat: Manhattan, KS • Fort Riley • Kansas State University • Manhattan Area Technical College

  4. Project Details • Campus for Several County Facilities • 10 Structures with Storage Yards • Approximately 70,000 square feet • 96 Acre site • Located at 6215 Tuttle Creek Blvd. • 5 Miles NW of Manhattan, KS on US 24

  5. Public Works Complex Locator Map

  6. Project Partners • Riley County Board of Commissioners • Architect • Anderson Knight Architects, Manhattan, KS • Mechanical Engineer • LST Consulting Engineers, Manhattan, KS • General Contractor • AHRS Construction, Bern, KS

  7. Campus Facilities • Public Works Operations • Road and Bridge • Fleet Services • Parks Department • Noxious Weed Department • Household Hazardous Waste • Emergency Management Storage

  8. Public Works Complex Facility Master Plan

  9. 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

  10. Current Progress • -Green Design • -Geothermal (Heat Pump) • -Natural Lighting • -High Efficiency Lighting • -Radiant Heating • -Heated Ventilation System

  11. Public Works Complex Green Design • Good candidate for LEED Certification • Use of energy efficient systems • Future use of renewable energy sources • Energy cost savings are considerable

  12. Public Works Complex Green Design

  13. Public Works Complex 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

  16. Public Works Complex Natural Lighting • Used extensively throughout the project • Allowed for a 50% reduction in number of light fixtures • Estimated 60% savings in energy costs

  17. Public Works Complex Natural Lighting

  18. Public Works Complex Natural Lighting

  19. Public Works Complex Natural Lighting

  20. Public Works Complex High Efficiency Lighting • T5 and T8 florescent light fixtures throughout • Use 35% less energy than old style T12 fixtures.

  23. Public Works Complex 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. 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

  25. 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

  26. 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

  27. Public Works Complex 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. Public Works Complex 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. 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

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

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

  33. 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

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

  35. Public Works Complex Project Summary

  36. Project Summary We began with a vision for Riley County as a leader inimplementing sustainabilitywithin the State of Kansas 1

  37. Project Summary 2 We identified sustainable technologies that would help us to accomplish that vision.

  38. Project Summary We are partnering with Johnson Controls to guide renewable energy system implementation and guarantee performance 3
