  8. 8. Needs Assessment <ul><li>Over 100,000 homes are weatherized each year </li></ul><ul><li>Even at this rate, only 16% of currently eligible households have received weatherization services </li></ul>
  9. 9. Income Qualification <ul><li>Eligibility for weatherization services is determined by income </li></ul><ul><li>Any household at or below 125% of poverty is considered low-income. A state may elect to use 150% of poverty as the guideline </li></ul><ul><li>Over 90% of low-income households have an annual income under $15,000 </li></ul><ul><li>Two-thirds have an annual household income under $8,000 </li></ul>
  10. 10.

  21. 21. House As A System <ul><li>Achieving true energy savings is the result of treating the dwelling as a system of three interactive parts </li></ul><ul><ul><li>Part One is the shell of the house which keeps cold air out in the winter and lets fresh air in during the summer </li></ul></ul><ul><ul><li>Part Two is the equipment in the home that adds to or makes the heat, air, and moisture move in your house </li></ul></ul><ul><ul><li>Part Three is the people in the home who control the shell and operate the equipment </li></ul></ul>
  22. 22. Health and Safety <ul><li>Weatherization providers encounter health and safety hazards during the estimation and work process and through their efforts – lives are saved on a daily basis </li></ul><ul><li>Unsafe heating systems can create life-threatening situations such as carbon monoxide poisoning, back-drafting, and fires </li></ul>
  23. 23. Health and Safety <ul><li>Lead-based paint, the number one environmental health threat to children, is a serious problem that weatherization, in conjunction with other funding sources, addresses before work is completed </li></ul><ul><li>Mold, moisture, high and low humidity are all health and safety issues that weatherization crews address on a daily basis </li></ul><ul><li>Dangerous electrical problems can also be addressed using weatherization funds </li></ul>
