  1. Stewardship of Energy

  2. Scripture • If you want to know me, look to my creation • How do we treat creation?

  3. Caring for Creation • Vision • Knowledge • Understanding • Persistence

  4. “And God Said” • You shall have dominion over the Earth • What does dominion mean to you?

  5. Agenda • Who we are • What we can do for you

  6. Who we are. • Center for Energy and Environmental Education at University of Northern Iowa • Evangelical Lutheran Church In America • Iowa Department of Natural Resources • Iowa Energy Center

  7. What we can do for you • Awareness • Energy Audits (Economic Development) • Implementation • 10 to 20% energy cost reduction (Every dollar saved is equal to a dollar in the collection plate) • Pollution Reduction (Stewardship)

  8. How your building loses heat Infiltration Convection Radiation

  9. InfiltrationCracks and Leaks Around • Doors • Windows • Outlets • Pipes • Foundation • Fireplace • Vents • 1 hr = a houseful of air

  10. Infrared photo of house

  11. Solution • Insulation • Caulk all air leaks • Interior/exterior storm windows • Replace weather-stripping • Draft Enders behind switch plates • Repair exhaust vent covers • Weather-strip attic access doors

  12. Types of Insulation

  13. Fire Place • Keep Damper Closed • Install glass doors on fireplace • 8% of heat can go up chimney

  14. Caulk • Inside & outside of all window and doors • Behind exterior wall baseboards • Inside & outside wall penetrations

  15. Have a caulking party !!

  16. Convection Windows Gain heat during day and Loose 2/3 at night • Install Low E argon filled windows • Install Pop-In Window insulation • Install Window Quilt • Close curtains at night

  17. Space Heating Options • General • Forced Air-Gas • Forced Air - Oil • Hot Water • Electric

  18. General • Setback Programmable Thermostat • Occupied - 68 Unoccupied - 45 • Thermostat away from heat source • Open drapes during day • Min. use of exhaust fans

  19. Set Back Thermostat

  20. Forced Air -- Gas • Keep filter clean • Change once a month • Registers free from obstructions • Oil motor and fan twice a year • Adjust fan belt once a year • Service furnace yearly • Insulate air ducts in unheated space

  21. Replace Furnace Filter once a month

  22. Forced Air Oil • Check flame for black tip -- service • Check for soot build-up - summer • Clean and oil hinges on damper • Change oil filter yearly • Service once a year • Check firing rate yearly

  23. Ducts • Leaks account for 13% of energy use. • Costs $110 per year • Cost $200 to fix • Tape seams • Mastic -- putty • Adhesive foil

  24. Hot-Water Space Heating • Check fluid levels regularly • Check expansion tank for air space • Bleed air from all radiators periodically • Insulate pipes • Keep radiators clean • Reflectors on back of radiators

  25. Insulated Pipes

  26. Electric Space Heating • Clean heating elements regularly • Check deflectors and aim • Do not block radiators • Check zone thermostat yearly

  27. Hot Water Heating 20% of energy used in the home Install 3” insulating blanket Set Thermostat between 110 and 120 Insulate Pipes All of the hot lines and first 6’ of the cold Take showers instead of baths Low Flow Shower Heads/Aerators Repair Leaky Faucets Promptly Turn Off when on vacation Drain 1 Gallon every 3 Months Removes Sediment Gas or Oil - Service once a year

  28. Insulate your Hot Water Heater

  29. Water temp. 110 to 120

  30. Appliances • Clothes Dryers • Clothes Washers • Dishwashers • Microwaves • Refrigerators • Ranges • Block Heaters

  31. Clothes Dryers • Keep lint filter clean • Operate with full load • Check dryer vent twice a year • Match temp. settings to fabric and load size

  32. Clothes Washer • Wash full loads or use lower water level settings for smaller loads • Use hot water only when necessary • Use cold water rinse cycle • Do not over wash

  33. Dishwasher • Wash full loads • Use shortest wash cycle possible • Use energy saver’ cycle if available • If not available, open door at end of rinse cycle and let dishes air dry

  34. Microwaves • Use for cooking vegetables or warming foods. • Do not use to defrost foods

  35. Refrigerators • Keep door closed (AMAP) • Keep Full and Defrost regularly • Turn off automatic ice maker • Turn off butter conditioner • Thaw food in p. • Cool foods before storing in Frig. • Locate away from heat sources • Clean Coils twice a year -- unplug • 3” air space in back • Keep door gasket in good repair

  36. Ranges • Use Solar Oven • Match Pots and Pans to element • Use min. water and cover pan • Use foil under elect elements • Use lids whenever possible • Turn off 15 to 20 Min. before cooking time is complete • Preheat only when required • Defrost food -- 50% less energy • Check door gasket • Don’t peek

  37. Block Heaters • Put a timer on the circuit, only needs to be on a hour or two before starting car • Plug car heater into same timer

  38. Understanding Kilowatt Hours • Wattage x hrs./1000 x cost = bill • Example • 10,000 x 40 hrs./1000 x .05 = $20 • This is a typical hot water heater

  39. Lighting = 16% Elect. • Open drapes • Light colored walls • Task lighting • Solid state dimmers • Turn off lights • Occupancy sensors • Timer for when you are out • Motion sensors outside • High pressure sodium

  40. Incandescent bulb 20% Light 80% Heat

  41. Lighting • Incandescent • 60 watt gives off 14.7 lumens per watt • Hot • Fluorescent • 40 watt gives off 80 lumens per watt • warm

  42. Exit Signs

  43. Indoor Water Conservation • When Shaving fill sink • When brushing teeth shut off water • Use Low flow Showerheads • Check for leaks • Toilet water level one inch below top of overflow drain

  44. Indoor Water Conservation • Wash dishes in basin • Operate dishwashers and clothes • Washers only when full • Use High efficiency washers • Don’t run water to • Wash vegetables • Thaw frozen food • Get glass of water

  45. Low Flow Showers saves the University of Northern Iowa $75,000 per year

  46. Outdoor Water Conservation • Water lawn between 4pm & 10 am • Water lawn only when it needs it • Place mulch around trees and plants • Plant native vegetation • Use automatic shutoff on garden hoses

  47. Landscaping Can reduce air conditioning cost Vines Keep 18” from house Hedges Trees

  48. The End
