Making Hennepin County a Cool County

  1. 1. Hennepin County
  2. 2. What is Cool Counties? A pledge to take action on Climate Change  Inventory greenhouse gas emissions from internal operations – Implement policies and programs to reduce emissions – Coordinate efforts with Minnesota State departments – Support state legislation that is consistent with Hennepin – County’s goals Urge action at the federal level to reduce emissions –
  3. 3. Why Join Cool Counties? Minnesota has already codified strict GHG  reductions Enhances existing HC policies & programs for  energy efficiency Ensures measurement & documentation of HC’s  emission reductions Provides direction to county departments 
  4. 4. Minnesota Goals Compared to Cool Counties GHG Emission Reduction Goals Cool County MN 100 90 80 70 % Goal 60 50 40 30 20 10 0 2010 2015 2020 2025 2030 2035 2040 2045 2050 Year
  5. 5. Compile an accurate emissions inventory Create emissions baseline and past 3-5 years – accomplishments 86 owned facilities, 57 leased facilities, 676 vehicles – Establish recordkeeping requirements and protocols; – identify responsible parties Recommend reductions from County operations – Review & Assess GHG monitoring and reporting protocols – Identify federal, state & other grant opportunities –
  6. 6. Hennepin County CO2 emissions • Based on self-reporting by individual departments in 2007 early 2008. Emissions not Libraries 4,971 accounted for include: ex City libraries, corrections, Mobile sources 6,693* tax forfeit property, or scope 3 emissions. Leased Buildings 8,226 • 2007 Emissions: Property Services 49,307 Direct 195,841 Energy Center 37,115 Indirect 70,475 HERC 160,004* Total (metric tons) 266,316 * = anthropogenic
  7. 7. Renewable Energy Projects Solar array at Public Works building  Wind Turbine at Public Works building 
  8. 8. Hennepin County Wind Turbine Project 1.5-2 MW wind turbine at PW Facility in Medina Clean Renewable Energy Bond awarded by IRS – Wind analysis completed by WindLogics – Project has Planned Unit Development (PUD) approval by – City RFP issued February 4, 2009 –
  9. 9. Solar energy projects Medina Public Works Building 80 kW  Panels mounted on beams above the roof – 528 modules 185 watts each – Completion in late February 2009 –
  10. 10. Transportation Increased percentage of bio-diesel  Shared E85 fueling station with City of Minneapolis  Adopted a new idling policy  Downsizing vehicles  8 hybrids, 186 flex fuel, 175 biodiesel  Experimenting with nitrogen filled tires  Converted 36 signals to LEDs, saving over 400,000  kWh / year
  11. 11. HERC • Constructed a steam line to the new Ball Park • Signed a Joint Energy Efficiency Plan with Xcel, including turbine replacement with potential annual savings of 15,000,000 kWh
  12. 12. Employee Programs All printers default to double-sided copying  Telecommuting, 2011 employees in 2007  Subsidized transit passes to encourage use  of public transportation
  13. 13. Outreach & Community Involvement • Launched a Cool County web site • Host an annual Cool County Fair • Produce a Green Notes e-newsletter
  14. 14. Buildings Government Center 1,501,950 sq. ft.  $2,970,000 in utilities/yr  3000 employees  20,000 tons of CO2/yr  13 tons CO2/1000 sq. ft. 
  15. 15. Recommissioning HCGC Study done in 2007, implementation in progress  10 year or less payback  Cost to implement ECO’s is $650,000  Energy savings estimated at $200,000 annually  Overall payback is 3.25 years  CO2 reduction of 1,800 tons annually 
  16. 16. The ECO’s 13% Lighting 37% Controls HVAC 50%
  17. 17. Big Ticket Items Lighting controls in courtrooms $20,000  Outside air adjustments $65,000  Reduce airflow when heating $20,000  Communication room transfer fans $25,000 
  18. 18. Current Plan Temperature set points 69°F and 75°F  Eliminate personal appliances  Expedite recommissioning of all buildings  Central Library study underway – HCMC completed – Remaining buildings – Continue to update controls systems  Replace old HVAC systems  Lighting, lighting, lighting 
  19. 19. Lighting Relamping from 32w to 25w tubes  Fixture upgrades  Occupancy sensors  County Government Initiative  One-stop lighting surveys – Increased rebates –
  20. 20. Lighting Savings Relamping libraries  220,000 kWh reduced so far  15-25% electrical cost savings  60% discount with CGI rebate  1 year payback  Reduction of 200 tons CO2 annually
