BPI generally stands for Building Performance Institute which is a group that certifies individuals on “building performance” measures.
Another “BPI” floating out there is the Building Performance Index (or as many say the BullS*** Performance Index) is a unique system being pushed by a few individuals as a way to “measure” the actual energy savings from the claims made.
Needless to say, almost every single reference made to BPI on this site is based on the organization and it’s programs. IMHO, while BPI does have some issues, utilizing another flawed metric or system will not help engender any more trust for those pushing it.
