Abstract
Seven test homes located in Massachusetts are examined within this report. The retrofit strategies of each home are presented along with a comparison of the pre- and post-retrofit airtightness achieved by the group. Pre- and post-retrofit utility bills were collected; energy models were used to estimate pre-retrofit energy use when bills were unavailable.
