The Building Performance Institute, Inc. (BPI) is proud to announce that BPI-2400-S-2012: Standard Practice for the Standardized Qualification of Whole-House Energy Savings Predictions by Calibration to Energy Use History, also known as the "Delta Standard," has been published as an American National Standards Institute (ANSI) standard.

Now if they take it one step further and include the registry Rick Gerardi writes about, they'll make this really meaningful.
