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 :ref:`bpi2101-use-case-defn`).
The Home Performance Certificate standard dataset is the most complex use case because it contains each of the following :ref:`building-node` nodes.
- Proposed workscope
Two :ref:`project-node` nodes are included as well that describe the proposed project and the completed project. It can be thought of as a combination of the :doc:`Audit and Upgrade <auditupgrade>` use cases.
