  1. REEPThe City of Houston’s Residential Energy Efficiency Program Everyone Benefits

  2. What is weatherization? • Definition according to Merriam-Webster on-line: to make (as a house) better protected against winter weather (as by adding insulation) • Clearly, this does not speak to climate conditions in Houston, Texas • What does weatherization mean in our region  • Home improvements that stop the cold and heat from entering homes, improving the quality of life of residents, reducing energy consumption, electricity bills and CO2 emissions.

  3. Residential Applications of Weatherization • New Construction • Design • Implementation • Existing Construction • Retrofit with like Components • Replace poor performing system

  4. Community and IndividualGoals

  5. How Does REEP Accomplish our Goals The Department of Energy reports that for every dollar spent, weatherization returns $1.53 in energy savings over the life of the measures, (http://www.energy.gov/news/5190.htm, retrieved 10/19/2009) • What are measures? • Air sealing-prevent unconditioned air infiltration • Insulation • Windows • Doors • Appliances-reduce the cost of essential appliances and lighting • HVAC • Refrigeration • Lighting

  6. Areas of Infiltration

  7. Measure Checklist • Foundation • Station and beam • Appliances • Exchange old inefficient appliances • Insulate Water Heater • Walls • Insulation • Penetrations • Doors • Windows cont’d

  8. Measure Checklist • Ceiling • Insulation • Batt • Blown • Penetrations • Attic • Venting • Attic Fans • Baffles cont’d

  9. Measures Checklist • Roof • Penetrations • Chimney • Combustion Appliance Venting

  10. Demographics of Reduced Consumption National Poverty Guidelines Family Size 200% monthly 200% annually 1 $ 1,805.00 $ 21,660.00 2 $ 2,428.33 $ 29,140.00 3 $ 3,051.67 $ 36,620.00 4 $ 3,675.00 $ 44,100.00 5 $ 4,298.33 $ 51,580.00 6 $ 4,921.67 $ 59,060.00 7 $ 5,545.00 $ 66,540.00 8 $ 6,168.33 $ 74,020.00 Weatherization can decrease subsidies by as much as 48%, (http://www.eia.doe.gov/oiaf/servicerpt/subsidy1/tax_expend.html , retrieved 10/19/2009)

  11. Measurement Tools • REEP Home Assessment • Blower Door Test • Isolate infiltration • Identify leaky areas • Energy Audit • Blower Door Test • Duct Blaster • Infrared Scan • See hot spots • Pinpoint infiltration

  12. ReductionStrategies • Replace appliances that are 7 years or older • Insulate attics to an R-value of 38 (R-38), Walls to R-13, • Weather-strip doors • Caulk windows • Compact Fluorescent Lighting (CFLs) • Insulate water heater

  13. Budget • Up to $6,500 per home can be allocated for weatherization measures, appliance exchange, doors and windows installation based on home assessment report.

  14. Measuring Effectiveness • Post Installation Inspections • Blower Door • Verification of Installs • Customer Satisfaction • Feedback • Quarterly Audits of Service Provider • Compliance
