  • 2. Green NeedhamCollaborativeSince 2012, Green Needham and Next StepLiving have: Signed up 1,089 residents for home energy assessments Almost 600 scheduled assessments, and 500 were completed in 2012 These assessments resulted in 162 weatherization jobs, which saved homeowners on average $500/year
  • 3. Mass Save
  • 4. Cape Style Home Weatherization Areas To Focus On  Attic Cap  Knee Wall Area  Slopes of the Upstairs rooms
  • 5. WEATHERIZATION A comfortable, safe, and energy-efficient home requires Continuous thermal boundaries and air barriers that are in contact with one another. (US.DOE)
  • 6. Typical Cape Attic 3 1
  • 7. #1 Kneewall Typically Insulated with fiberglass or nothing at all Even though insulation is present, air movement around insulation and thermal breaks
  • 8. Knee Wall Application Adding Foam Board (Polyiso) on top of existing insulation Sealed with spray foam Insulates and Air Seal
  • 9. #2 KWL Floor and Transition Typically the KWL Floor is not insulated KWL transition extends 2 feet into living space

  • 16. Heat Loan Helps Support HighEfficiency Heating Systems: Oil Customers can save 40-50% in heating costs by switching SinglePane to Double Pane Windows Conversion: Least Cost Effective energy efficiency option, but may be necessary with older homes
