  1. Regional Technical Forum October 9, 2007 Portland Oregon

  2. Random Home Study Details • Field study on manufactured homes built to current Energy Star specifications • Work will be carried out on at least 114 units • Sample size being dictated by the expected coefficient of variation in the key measurements (e.g. duct tightness and envelop air tightness). • Sampling provides adequate state-by-state samples in the states of this region. • 38 sites for Oregon, and 43 sites for Washington, and approximately 35 sites in Idaho and western Montana.

  3. Specific field activities: • Measure tightness of building shell and duct system • Measure airflow and static pressure in the HVAC system in order to calculate supply leakage fraction (which has direct bearing on overall heating system delivery efficiency) • Measure flow rate through whole-house exhaust fan • Evaluate compliance of home set-up with statewide set-up rules • Record other key data which have a bearing on home performance and occupant health/safety (such as whole house fan run-time, house size, auxiliary fuels, etc) • Datalog lighting, hot water and heating loads

  4. Exterior Duct Leakage (Previously Reported)

  5. In-plant training for Duct testing

  6. Supplemental Lighting Study • Manufactured home have separate lighting circuits • Simple integrating CTs could provide lighting sub metering • Lighting audit would provide LPD for home • Analysis would derive the average lighting runtime for the metered period. • No lighting loggers required!

  7. Proposed Funding • ODOE contribution (USDOE BAIHP) - Committed 35880 • Fees from manufacturers & SEO inkind - Committed 25000 • Northwest Energy Efficiency Alliance (amount requested) 25000 • Regional technical Forum (amount requested) 10000 • Bonneville Power (amount requested) 40000 • IOU utility 5K each (amount requested) 15000 Total 150,880

  8. Supplemental Funding needed (not in the above budget) • Lighting monitoring and audit: • Equipment: 50 homes 25000 • Audits, placement 10000 • Analysis 15000 • DHW review (sub-metered) 20000 • Mini-Split review 5000 Total supplemental 75000
