    Abstract
    This memorandum reviews the differences in measured energy savings from 102 Alaska weatherized homes (ISER 1993) compared with savings from a "cold-climate" region of the United States (ORNL 1993). The National study found a significantly higher level of gross energy saving (12.5%) in its sample of 1040 gas-heated homes than the Alaska study found in is sample of 102 homes. Alaska' lower level of percentage gas savings, relative to the US cold-climate region, cannot be attributed to differences in sampling, data retention, or analytical technique using PRISM. When measured by gas consumption per degree-day, the Alaska sample of weatherized homes appears to have higher thermal integrity prior to weatherization. From different starting points, both Alaska and US single-family homes appear to be achieving a post-weatherization thermal integrity of about .155 cf per degree-day. Alaska mobile homes reach a roughly similar final level of .142 ccf per HDD, commensurate with their smaller size.
