Progress in Residential Retrofit CBS Newsletter Winter 1993 pg. A geographic representation of saturations of ceiling fans based on data from the RASSes.
White areas indicate a lack of data for that region.
Many utilities survey their customers to learn more about the buildings and the occupants in their service areas. The RASSes are also used to collect information about the presence of conservation measures such as wall and ceiling insulation, weatherstripping, multipane windows, and water flow restrictors. Building Energy Analysis Group researchers Alan Meier and Brian Pon gathered RASSes from more than 100 utilities for recent research on the nation's progress in residential retrofit. Average saturation levels of conservation measures were calculated from these RASSes. The principal advantage of using RASSes is that each RASS surveys a large number of consumers.
