# Home Performance Certificate (BPI-2101)¶

BPI-2101-S-2013 Standard Requirements for a Certificate of Completion for Residential Energy Efficiency Upgrades (“Home Performance Certificate”) is a BPI standard that identifies a subset of HPXML data elements for certificates that document the completion of an energy efficiency project, either whole-house or individual measures (See Home Performance Certificate).

The Home Performance Certificate standard dataset is the most complex use case because it contains each of the following Building nodes.

See the examples/bpi2101.xml document for more details on what data elements are included.
