  • Overall Reduction 1. Babbott/Ward (49.73%) 2. Dunlay (49.18%) 3. Phillips (47.43%)October Reduction 1. Urell (54.73%) 2. Dunlay (54.40%) 3. Phillips (51.54%)November Reduction 1. Babbott/Ward (54.36%) 2. Phiilips (43.90%) 3. Dunlay (42.62%)Greatest Cumulative kWh Reduction 1. Phillips 2. Lawry 3. Babbott/WardLowest Monthly kWh Recorded 1. Dunlay (140 kWh) 2. Bender (185 kWh) 3. Kendall (206 kWh)Don: 12,651 KWH is about equal to the average annual home demand in the US. For Weston, the average annual KWH in FY2008 was 18,400 KWH. I suggest saying that the KWh saved via CCC1 is 8 months of demand for one average Weston household. The above figures come from the Envn Baseline Comm report to be presented to the Selectmen in the next few months.
  • If you want to shrink your household’s carbon footprint, the best place to start is with the heating and cooling systems, which account for 44 percent of the average home&apos;s energy use. Cut the energy used to cool and heat your home by 20 percent and you will have reduced your overall household energy use by 8.8 percent. (For the sake of comparison, a corresponding improvement in lighting efficiency will cut your energy use by 2.2 percent.)Source: http://www1.eere.energy.gov/eere_faq/detail_search.aspx?IDQuestion=388&amp;pid=10&amp;spid=2

    2. 2. Overview<br />Case Study<br />Financials<br />Next Steps<br />Q&A<br />Carbon Crunch Challenge<br />
    3. 3. 42 Households, 10 Teams, 3 Towns<br />October kWh reduction<br />CCC Participants: 16.30%<br />All Weston Residents: 4.55%<br />November kWh reduction<br />CCC Participants: 9.87%<br />All Weston Residents: 2.51% <br />CCC 1.0 : Killing Watts<br />
    4. 4. Average Overall Total Reduction<br />CCC Participants: 13.10%<br />All Weston Residents: 3.56%<br />Average Net kWh Reductions ‘08-’09<br />CCC Participants: 275 kWh<br />Weston Residents: 91 kWh<br />Total 2 Month Net kWh Reduced by all CCC Participants: <br />CCC 1.0 Made a Difference<br />12,651 kWh<br />≈ 8 Months of Demand for <br /> 1 Avg. Weston Household<br />
    5. 5. Home heating & cooling systems account for 44% of the average home’s energy use<br />A 20% reduction decreases overall household energy use by almost 9%<br />Home energy assessments usually identify reduction opportunities of 20-30%<br />That’s a saving of roughly $600-900/year, every year, based on average annual heating costs<br />Our Next Target: Home Heating<br />
    6. 6. Goal: Reduce household heating energy used in January & February 2011 as compared to those same months in 2010<br />Process:<br />Contact MassSave for a free Home Energy Assessment<br />Use the results to make changes<br />Report your Jan & Feb heating oil or natural gas use to the CCC organizers<br />Save a lot of money & be happy<br />Carbon Crunch Challenge 2.0<br />
    7. 7. Single-family home in Roslindale, MA*<br />Blower Door & Infrared Inspection<br />Performed by Byggmeister, Inc.<br />October 7, 2008<br />The Case of David Carrier<br />* This isn’t his house, <br /> just a great IR picture<br />
    8. 8. Attic & basement showed plenty of leakage<br />Wall insulation generally acceptable, although infrared shows coverage uneven<br />Major air leakage in an inner partition wall & kitchen ceiling<br />Fireplace flue did not seal well<br />General Observations<br />
    9. 9. Tub access panel very leaky & cold with blower door running<br />Second Floor Bathroom<br />
    10. 10. Should be air-sealed and insulated<br />Rim Joist Area in Basement<br />
    11. 11. Registered lots of air movement; should be air sealed<br />Chimney Case<br />
    12. 12. Air leak from second floor bathroom into bedroom through wall outlet<br />Cold Air Leaking through Outlet<br />
    13. 13. Upgrade insulation & air-seal attic<br />Spray foam the band joist area around perimeter of basement<br />Air seal & insulate overhang under kitchen<br />Air seal & insulate behind 2nd floor tub<br />Listed 6 resources to help with insulation & air sealing work<br />Report Recommendations<br />
    14. 14. Returns to energy efficiency are measured as the sum of averted energy expenditures verses the capital cost to implement over the useful life of an improvement.<br />Economics of Energy Efficiency<br />
    15. 15. Conceptual Model<br />Savings: Informed by Energy Assessment and determined by the change in equipment efficiency (new vs. old), the relative consumption impacted and a host of other factors including weather, fuel prices, behavior, etc.<br />Costs: Capital costs are driven by the choice of efficiency measures and offset by rebates, financing opportunities, tax credits, etc. <br />
    16. 16. Savings are more difficult to predict than capital costs and are building dependant<br />Typical savings in residential retrofits average 25% of energy costs, or ~$600.<br />Larger energy users or less efficient homes may see larger savings.<br />Home Energy Assessments are a good tool to understand current use and expected/potential savings.<br />Predictions<br />
    17. 17. Capital Costs are generally known in advance and can be significantly reduced through available incentives:<br />Incentives can take multiple forms including:<br />-Rebates<br />-Below market financing<br />-Tax credits<br />-Other<br />Capital Cost Reduction<br />
    18. 18. Incentives<br />Incentives can take multiple forms including:<br />-Rebates<br />-Below market financing<br />-Tax credits<br />-Other<br />
    19. 19. Incentives Overview: Rebates<br />Offered through the utility on qualifying energy efficiency improvements across a wide array of efficiency products.<br />Substantial rebates exist on:<br />-HVAC (up $1,000)<br />-Hot Water (up to $700)<br />-Insulation (75% up to $2,000)<br />-Other (thermostats, boiler resets, etc.)<br />-Financing (0% Interest)<br />Incentive details can be found at:<br />www.masssave.com<br />

    22. 22. Incentives Overview: Financing<br />The HEAT Loan program offers 0% loans up to $15,000 for households with good credit for terms up to 7 years.<br />Home assessment is a precondition of the loan<br />Only available for energy efficiency improvements<br />
    23. 23. Incentives can take multiple forms including:<br />-Rebates<br />-Below market financing<br />-Tax credits<br />-Other<br />Incentives<br />
    24. 24. Incentives Overview: Tax Credit<br />Federal Tax Credit for 30% of qualifying project cost up to $1,500 in 2010<br />Tax credit expires 12/31/10<br />Tax credit can only be used once (2008-2010)<br />
    25. 25. Incentives<br />Incentives can take multiple forms including:<br />-Rebates<br />-Below market financing<br />-Tax credits<br />-Other<br />
    26. 26. Other Ways to Reduce Capital Costs<br />There are other ways to lower the capital cost of energy efficiency including bidding work during seasonally slow periods and/or soliciting multiple bids.<br />Example – Ask your heating system contractor if they offer discounts during the seasonally slower summer season.<br />
    27. 27. Discounts & incentives can be a substantial portion of the total project cost as shown in the hypothetical example below:<br />
    28. 28. Other Considerations<br />Rebates, tax credits and other incentives fluctuate from year to year.<br />2010 incentives are very generous vs. history and may not be representative of future years<br />Potential legislation (example – Home Star)<br />
