  2. 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. 3. Mass Save
  4. 4. Cape Style Home Weatherization Areas To Focus On  Attic Cap  Knee Wall Area  Slopes of the Upstairs rooms
  5. 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. 6. Typical Cape Attic 3 1
  7. 7. #1 Kneewall Typically Insulated with fiberglass or nothing at all Even though insulation is present, air movement around insulation and thermal breaks
  8. 8. Knee Wall Application Adding Foam Board (Polyiso) on top of existing insulation Sealed with spray foam Insulates and Air Seal
  9. 9. #2 KWL Floor and Transition Typically the KWL Floor is not insulated KWL transition extends 2 feet into living space
  10. 10. KWL Floor Application Dense Pack the Floor and Transition with Blown in Cellulose Holes are drilled in floor, hose delivers insulation, holes are sealed up KWL area treatment often improves more than one room: the adjacent bedroom and the living space below!
