Leadership in Environmental Stewardship in a Fiscally Prudent Manner

1. WAUKESHA COUNTY SUSTAINABILITY EFFORTS Leadership in Environmental Stewardship in a Fiscally Prudent Manner

2. County Executive called for Sustainability Initiative • First Sustainability Plan 2008-2010 • County Board Adopted Sustainability Policy • Updated Sustainability Plan 2010-2014 • Return on Investment closely monitored

3. Energy Use Benchmarking • Collected and Analyzed 6 years of data for baseline. • Placed all data for buildings in EPA’s Portfolio Manager software. www.energystar.gov • Building energy analysis by Focus on Energy and other consultants to detail needs. • Implementing Focus on Energy and consultant recommendations results in 19% energy savings by year 2025.

4. Ice Arena HVAC Upgrades • “Waste Heat” Use • Installed a dehumidification system that uses "waste" heat from the ice chiller system to dehumidify the Ice Arena in place of a natural gas dehumidifier. • Estimated 60% Natural Gas Reduction • 6 year ROI

5. Lighting - Roadways • LED signal heads vs. incandescent bulbs cost savings is $70,500 (3 yr ROI) • LED luminaries (street) lights are 75% more efficient than former high pressure sodium bulbs

6. Lighting – Parking Lots • Exposition Center – LED replacement of 72 parking lot lights. 70% reduction in electrical cost. $4,800 annualreduction • Design underway for all other Government Campus parking lot lighting. Installation by year end.

7. Lighting - Interior • Installed motion detectors in various facilities in common rooms such as conference rooms • Law Enforcement Center • 966 lighting fixture upgrades • energy savings of 23% to 41% depending on the fixture • Exposition Center • 273 lighting fixture upgrades • energy savings of 30% to 90% depending on the fixture • Less than a 3 year ROI

8. Geothermal Analysis • Retzer Nature Center • 40-ton vertical closed loop system • Borefield: 20 wells at 300 feet • 9 existing furnaces and 5 air condition condensing units • Used in Learning Center, Planetarium and Maintenance Building • Estimated 40 – 60% Energy Savings; 13 year ROI • Proposed Health and Human Services Building • Proposed 138,000 square foot building • Projected natural gas use 11% of total energy use • Geothermal ROI over conventional system – 53-66 years • Project not pursued further

9. Solar Hot Water • Retrofitted domestic natural gas hot water heating system with a solar heating system in the County Jail. • The building houses 346 inmates and 50 employees. • Annual savings of 4,640 therms and 552 kWh • Anticipated ROI 10 years • Incentives of $96,000, $48,000 from Focus on Energy & $48,000 from WE Energies

10. Solar Hot Water • Evaluated a retrofit of domestic natural gas hot water heating system with a solar heating system at the Law Enforcement Center. • The building houses 192 inmates and 80 employees. • includes a cafeteria and kitchen that serves on average of 2,400 meals per day. • Anticipated ROI 20 years. • Project not pursued further.

11. Lessons Learned • Administrative and Policy Support is Essential • Benchmark current conditions and track facility energy use • Take a business approach to selecting projects (ROI) • Work Closely with Focus on Energy Representative • Pursue and Reinvest Rebates
