Standard Data Collection Templates

HPXML includes four data collection templates that program administrators can use to standardize data collected at specific points during the implementation of a program.

HPXML includes four data collection templates that specify a number of required data elements from the HPXML data dictionary that can be collected at specific points during the implementation of a residential energy efficiency program.

The templates fall into two categories. The Audit and Upgrade templates standardize data collected for the transfer of project and energy consumption data from third-party energy modeling or data collection tools to a program management database. Home Energy Score and the Home Performance Certificate standardize the transfer of information about a home's energy efficiency features and performance to Multiple Listing Service systems.

The Audit and Upgrade templates were established through a consensus process of three geographically diverse existing whole-house programs, and are intended to meet the needs of most programs. New data collection templates will be created and published as needed.

One of the areas in which data standardization holds the greatest promise is in data collection and reporting. If different programs all agree to collect the same (or very similar) data for the same use cases, information technology costs could be reduced significantly across the country.

Standard data collection templates also would greatly facilitate cross-program comparability, and support research and the accurate quantification of energy savings.
