  • Make sure updated is most recent date file is changed GB –it is doneGeneral notes on whole document: “and” and “&amp;” are used interchangeably – would be better if they were the same but I do not know how to do replace all in the current version of PPT. Need to insert page numbers on slides – I do not know how. (ACI Eric does) GB –Go to View/header-footerOn imported AIM Associates documents / drawings seems like there is room and AIM Associates should be pasted in GB –it is doneWould be great to have a slide addressing your durable window trim and flashing system. GB –it is done
  • George – great place for photo of you and your wife!GB I added before at the end but I agree it is better to put here. I hope you do not think this “family portrait” is too “earthy”.
  • George - Is this the correct way to list it - Low-E2 Make sure it is consistent throughout documentGB – Yes I will
  • Photovoltaic should be one word (2)Finish is spelled incorrectly – (Steel Roofing with Energy….)New Low-E …. Should be ‘windows stop ‘not ‘windows stops’
  • Photovoltaic – should be one word
  • George – great place for photo of you and your wife!
  • George – great place for photo of you and your wife!
  • (LW) George – Do you want ASSOCIATES to be all on one line?Yes, I changed it from the nicer “Futura Condensed” to Arial Narrow

    1. 1. Thousand Home ChallengeIntro to Indicators of Performance<br />George Beeler, AIMA S S O C I A T E S<br />Petaluma, CA george@aimgreen.com<br />For more information: Linda Wigington, ACI <br />724-852-3085lwigington@affordablecomfort.org<br />www.affordablecomfort.org<br />9/12/2010<br />
    2. 2. Purpose of this Power Point:<br />Introduce the Thousand Home Challenge (THC)<br />Review the criteria for meeting the Thousand Home Challenge<br />Show case study: Beeler live/work, rehabilitation of 1940 energy hog, Petaluma, CA<br />
    3. 3. The Thousand Home Challenge is designed to:<br /><ul><li>Reduce the energy consumption of existing homes by 70-90% (total use, not just space conditioning)
    4. 4. Develop indicators of home energy performance
    5. 5. Exemplify the performance-based systems design approach
    6. 6. Assemble local / regional centers of excellence
    7. 7. Stimulate collaboration, creative problem-solving, and innovative products and approaches</li></li></ul><li>How is the Thousand Home Challenge Unique?<br />Bottom line – actual total use, not modeled<br />Key metric - Customized household energy use threshold allowance<br />Behavior, lifestyle, community solutions on map<br />Stimulate creative solutions; Lots of potential paths<br />Thousand Home multiplier – vision for scalability <br />
    8. 8. Optimize Investment<br />Customized based on goals, opportunity, resources, & needs<br />Multiple paths to get to deep reductions!<br />
    9. 9. Not Included in THC but Very Important<br />Embodied Energy – food, energy, consumables, waste, building materials <br />Transportation Energy<br />

    11. 11. Two Options for QualifyingMeet or exceed a household energy allowance<br />OPTION A<br />Relative, 75% reduction<br />Annual measured use – pre and post<br />Best for higher use households<br />OPTION B<br /> Absolute, not relative: customized by household <br />Inputs – climate, house size, #of occupants, heat source<br />Best – Low Use households or those without pre-use<br />
    12. 12. Option BProportional to the Opportunity<br />Responsive but not linear<br />House Size – thermal loads are not strictly linear <br />Occupancy – More people use more energy, but not linear<br />Climate – In mild climates heating & cooling loads should be eliminated<br />
    13. 13. OPTION B: Customized Household Threshold<br />Estimates energy needed for a very high performance house for<br />Heating<br />Cooling<br />Hot Water<br />Everything Else<br />Sum is the actual site energy household threshold that must be met or exceeded in order to meet the Thousand Home Challenge<br />
    14. 14. How is Solar Counted?<br /><ul><li>Passive solar & active solar thermal systems offset energy use
    15. 15.
