11. From this, we can determine some of the County’s biggest energy users by various factors and look for ways to scale back usage, improve efficiency, and implement renewable technologies.

13. Employee Awareness and Behavior Modifications • Lighting • Computers • Office Equipment • Personal Devices and Other Appliances • The Thermostat Image courtesy of Wisconsin Environmental Education Board http://www.uwsp.edu/cnr/weeb/

14. Employee Awareness: Lighting • The average price per kWh in County facilities is roughly $0.115 • A single lighting fixture uses 32 – 96 watts every hour it is switched on. • From my observations in County buildings:

15. Employee Awareness: Computers • Laptops use around 50 watts per hour, PCs use between 80 and 140 watts per hour. • Group Policies – computers go into “sleep” mode after 1 hour, monitors after 15 minutes • Sleep still uses about 5 watts per hour • Unplug for best results. Yearly Usage and Cost Estimates

16. Employee Awareness: Office Equipment • Employees don’t usually think to unplug or power down these devices. • Power strips can be a good option and are already widely used in County facilities. Yearly Usage and Cost Estimates

17. Employee Awareness: Personal Devices and Other Appliances • Break room equipment: Fridge - 1500 kWh/year, Coffee pot - 150 kWh/year, Microwave - 120 kWh/year • Personal devices – my laptop uses 30 watts per hour and my phone charger uses 5 watts per hour.

18. Employee Awareness: The Thermostat • In summer every degree above 75°F can save 1-3% of a building’s cooling costs. • Focus on Energy Estimates that setting the thermostat 1°F lower in winter can save up to 1% of a building’s heating bill.

19. What Can I Do as an Employee? • Shut off unused lights • Use less artificial light - dual switching if it is an option or natural light if there is a window. • Request an occupancy sensor or more energy efficient light bulbs for desk lamps. • Use energy - saving computer settings. • Shut down your computer when you leave (over lunch, during meetings, in the evening). • Shut off your own office equipment (printers, fax machines, etc.) and shared equipment when not in use. • Consolidate other equipment – share coffee pots, microwaves, refrigerators, etc. between departments. • Dress for the weather and set the thermostat a little lower in winter and a little higher in summer. • Give feedback, help and encourage your peers to reduce their energy consumption. • All actions can be copied at home for personal energy savings as well!

20. Example: Jail Kitchen Hood Current Usage and Cost for the Jail Kitchen Hood (11 hours ‘on’ per day) • Possible Savings for the Jail Kitchen Hood (reduction of 6 hours ‘on’ per day)

21. De-lamping • Sandy at Portland Street Annex has already requested this action. • Savings per year: • This can be done with nearly any 2, 3 or 4 lamp fixture for an average savings of about $7.75 per fixture per year. • Good option for over-lit offices, hallways, etc. without a double switch option.

22. Low cost Actions

23. Switch to Lower Wattage Lamps • Replace any existing Incandescent bulbs with CFL bulbs– longer life and lower energy costs. • Replace any existing T12 lamps with T8 lamps (Electric payback of 900 – 1000 hours). • Use low wattage T8 lamps and appropriate ballasts – 28 or 25 watt lamps with programmed start ballasts will save the most energy in the long-term.

24. Installation of the Vending Miser • Appropriate locations throughout the County include but are not limited to: • Government Building • Safety Building • Healthcare Center • Fairgrounds • Mitch Showers at UW Fond du Lac has already successfully implemented several of these.

25. Installation of Occupancy Sensors • Cost for a wall mounted occupancy sensor is about $65 • Cost for a ceiling mounted occupancy sensor is about $123 • Example for a given bathroom: • Focus on Energy gives a conservative estimate of 15%. Depending on application, the EPA suggests 30 – 90 % for bathrooms. • Focus on Energy also offers prescriptive incentives of $7.50 per wall mounted sensor and $15 per ceiling mount occupancy sensor installed.

26. LED Retrofits for Wall Mounts, Outdoor Canned Light Fixtures and Parking Lot Lighting

27. Higher Cost Actions

28. HVAC Suggestions from Focus on Energy • Switch from Pneumatic to Direct Digital Controls where applicable • Use Variable Frequency Drives for motors on pumps • Install ECM motors (Electronically Commutating Motors) on evaporator fans • Install a Heat Recovery System for Water Heaters in the Government Building

29. Renewable Projects

30. Solar Electric

31. Solar Water Heating • $300,000-350,000 estimated total install cost. • Estimated annual production is 458,933,049 Btu, which is 4,590 Therms. • Annual savings - $3,605 • Payback without aid is 83 to 97 years, with max aid is 58 to 68 years.

32. Future Considerations

33. Efficiency • Keep buildings well insulated • Make energy efficient replacements at failure of equipment Appliances • Energy Star rating for new equipment purchases such as office equipment, ice machine and laundry in Healthcare Center, etc. Renewable Technologies • Wind spire turbines (Rough estimate - $15,000 for one spire, produces about 2000 kWh per year, 68 year simple payback) Other • Double sided printers (automatic eco settings) • Can, bottle and paper recycling in buildings and at events. • Encourage carpooling, taking public transportation, walking or biking to work.
