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 bpi2101-use-case-defn).
The Home Performance Certificate standard dataset is the most complex use case because it contains each of the following building-node nodes.
- Pre-upgrade
- Proposed workscope
- Post-upgrade
Two 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 Audit and Upgrade <auditupgrade> use cases.
Finally, consumption-node and utility-node nodes are also included to provide a utility billing history.
See the examples/bpi2101.xml document for more details on what data elements are included.
