  1. Status of the Data Collection • Completed • State and Agency Surveys • Indoor Air Quality Study • Bulk Fuels Study • Large Multi-family Buildings Study • In Progress • Utility Bill Collection • National Occupant Survey • National Weatherization Staff Survey • Weatherization Training Center Survey

  2. Status of the ARRA Evaluation • Evaluation Plan is complete. • One more round of surveys and utility data collection, focus on PY10 • Targeted evaluations of WIPP and SERC • Other studies: persistence of energy savings, assessment of under- and over-performers, social network analysis • Information Collection Request has been submitted to OMB for approval. Projecting an early winter start date for data collection.

  3. Indoor Air Quality Findings • Carbon Monoxide • No homes exhibited peak ambient CO problems • Radon • 4% of site-built homes went from below EPA threshold (4 pC/L) pre-wx to above post-wx • Formaldehyde • Net increase of 5.1 ppb post-wx in mobile homes • Temperature • Virtually no change in settings post-wx

  4. Occupant Survey Findings* • Occupants’ reported home temps • Winter: 51% comfortable; 36% cold; 9% very cold • Summer: 62% comfortable; 25% hot; 8% very hot • Occupants’ report health • Asthma: 21% reported; of these 11% ER visits last 12 months • Physical health not good last 30 days: 45% • Mental health not good last 30 days: 34% * From IAQ Study

  5. Program Characterization Findings

  6. Program Characterization Findings: Frequency of Measures Installed (PY08) • Air Sealing - ~95% (e.g., 90% bypass sealing, 75% general caulking, 35% duct sealing) • Insulation - ~75% units (e.g., 70% attic, 25% wall, 20% floor) • Hot Water Measures – 60% units (e.g., 40% pipe insulation, 9% replacement) • Energy Efficient Lights -- ~60% • Furnace Work -- ~45% units {20% tune-up, 20% new system, 10% repair} • Windows – 40% units (e.g., 20% new, 20% glazing, 10% repairs) • Doors – 35% units • Health & Safety – 80% units • CO monitor – 55% • Smoke Alarm – 45% • Ground vapor barrier – 15% • Attic ventilation – 15%

  7. Projected Publication Dates • National Energy Savings Estimates – PY07 & 08: Dec. 2011 • Program Characterization – PY 08: Dec. 2011 • IAQ Winter and Summer Studies: Dec. 2011 • Program Eligibility – PY08: Feb. 2012 • National Occupant Survey – Pre-WX: Feb. 2012 • Case Studies – March 2012 • Field Process Study – March 2012
