May 15, 2003
If you benchmarked your building using Cal-Arch prior to May 15, 2003,
your results may differ if repeated on the current version. This is
primarily due to the removal of statistical weighting. While the weights
extrapolated the sample to represent a larger population, the emphasis
here is on actual buildings and actual data, and removing the weights
allows for the addition of data from other sources including individual
building data. Your results could change again when new data are added or
updated as they become available.
Changes have also been made to climate
zones and graph types.
