Energy $ense Saving on Home Energy Bills - Oct 2008

  1. 1. Cutting Home Energy Bills Fred Schlicher Program Manager Mass Climate Action Network [email_address]
  2. 2. Special Thanks <ul><li>Marc Breslow, Director of Transportation & Building Policy, Mass. Exec. Office of Energy & Environmental Affairs </li></ul><ul><li>Michael Blasnik, M. Blasnik & Associates of Boston, Mass. </li></ul>
  3. 5. Four Basic Approaches <ul><li>Behavioral – Lifestyle changes you can make </li></ul><ul><li>Appliances – Items you can buy </li></ul><ul><li>Weatherization Investments – Home improvements </li></ul><ul><li>Education – Reliable sources of information to help you become an educated consumer </li></ul>
  4. 6. Structure & Objective <ul><li>Behavior </li></ul><ul><ul><li> Low Carbon Living </li></ul></ul><ul><ul><li> Low Carbon Diet </li></ul></ul><ul><li>Appliance </li></ul><ul><ul><li> Products </li></ul></ul><ul><ul><li> Rebates </li></ul></ul><ul><ul><li> Appliances (fee) </li></ul></ul><ul><li>Weatherization </li></ul><ul><ul><li> HERS raters for Mass. </li></ul></ul><ul><ul><li> Guide to Energy Savings </li></ul></ul>
  5. 7. Behavioral Lifestyle changes you can make <ul><li>Hot water use </li></ul><ul><li>Heating & cooling </li></ul><ul><li>Lighting </li></ul><ul><li>Electric use reductions </li></ul>
  6. 8. Hot Water Use <ul><li>Adjusting hot water heater </li></ul><ul><li>Insulate heater </li></ul><ul><li>Shorter showers </li></ul><ul><li>Hand dish washing </li></ul><ul><li>Wear clothes longer </li></ul><ul><li>Washing with cold water </li></ul>
  7. 9. Additional Hot Water Tips <ul><li>When replacing a water heater, buy the most efficient one available, and don’t buy more capacity than you need. </li></ul><ul><li>Put “cut-off” switch on your </li></ul><ul><li>Shower head, and reduce flow when </li></ul><ul><li>full pressure is not needed. </li></ul>
  8. 10. Heating & Cooling <ul><li>Turn down thermostat </li></ul><ul><li>Change A/C filter frequently </li></ul><ul><li>Regular tune up of furnace or heat pump </li></ul><ul><li>Seal windows and doors </li></ul>
  9. 11. Air Sealing <ul><li>Rope caulk along edges of windows </li></ul><ul><li>Clear plastic on windows </li></ul><ul><li>Weather stripping on edges of doors </li></ul><ul><li>Plug holes in ceilings, floors, walls with caulk, fiberglass, plastic, etc. </li></ul><ul><li>Foam inserts for power sockets & switches </li></ul>
  10. 12. Lighting <ul><li>CLF’s use ¼ the electricity for same amount of light, blub lasts 7 to10 times as long </li></ul><ul><li>Turn lights off when no one in room </li></ul>
  11. 13. Electric Reductions <ul><li>Phantom load reduction with power strips </li></ul><ul><li>Determine power eaters with “Kill A Watt” meter and economize use </li></ul><ul><li>Energy appliance purchases </li></ul>
  12. 14. Energy Star Appliance Purchases <ul><li>New hot water heater $350 </li></ul><ul><li>New dish washer $450 </li></ul><ul><li>New washer and dryer </li></ul><ul><li>New refrigerator $550 </li></ul>
  13. 15. Additional Appliance Tips <ul><li>DON’T buy a plasma TV </li></ul><ul><li>Buy a gas-fired clothes dryer </li></ul><ul><li>Buy a front-loading, high-speed </li></ul><ul><li>washing machine (the clothes </li></ul><ul><li>come out much dryer, reducing </li></ul><ul><li>dryer time) </li></ul><ul><li>Turn computers & other electronics off when not in use </li></ul>
  14. 16. Heating & Cooling Purchases <ul><li>New programmable thermostat $35. </li></ul><ul><li>New furnace or heat pump $3500. </li></ul>
  15. 17. Additional Heating & Cooling Tips <ul><li>Boiler – efficient, well-tuned & cleaned </li></ul><ul><li>Insulation, windows – don’t let heat escape through roof, walls, windows, basement </li></ul><ul><li>Don’t waste heat – use thermostat to provide heat only when needed </li></ul>
  16. 18. Lighting <ul><li>Installation of additional CFL fixtures </li></ul><ul><li>Motion detector for security </li></ul><ul><li>lighting </li></ul>
  17. 19. Weatherization Major Home Improvement Investments <ul><li>Sealing air leaks </li></ul><ul><ul><li>Attic </li></ul></ul><ul><ul><li>Basement </li></ul></ul><ul><ul><li>Plumbing stacks, walls without top plates, etc. </li></ul></ul><ul><li>Insulation installation </li></ul><ul><ul><li>Empty walls </li></ul></ul><ul><ul><li>Empty attic </li></ul></ul>
  18. 20. Air Leakage Paths <ul><li>Attics & basements usually 50%-75% of leakage </li></ul><ul><ul><li>plumbing stacks </li></ul></ul><ul><ul><li>walls without top plates </li></ul></ul><ul><ul><li>ceiling height changes </li></ul></ul><ul><ul><li>chimneys </li></ul></ul><ul><ul><li>soffits </li></ul></ul><ul><ul><li>recessed lights </li></ul></ul><ul><ul><li>foundation walls </li></ul></ul><ul><li>Windows and doors typically 10%-15% </li></ul>
  19. 21. Blower Door Air Leakage Analysis <ul><li>Measure leakage </li></ul><ul><ul><li>before & after </li></ul></ul><ul><li>Help find big leaks </li></ul><ul><li>Assess ventilation </li></ul><ul><li>Requires training </li></ul><ul><li>works well with infra-red camera </li></ul>
  20. 22. Infra-red Camera <ul><li>Assess current level of insulation in walls and spot gaps </li></ul><ul><li>Check results of contractor work and if additional remedial work is needed to complete job </li></ul>
