HPC Submits Comments to RESNET on Proposed Data Access Policy
Building Performance Association submitted comments to the Residential Energy Services Network (RESNET) Board on November 30, 2017 on its proposed policy on RESNET access to data in the RESNET National Buildings Registry.
The RESNET National Buildings Registry contains multiple significant data points about a home’s performance and energy attributes that can impact its value if that information is available to homebuyers, realtors, appraisers, and lenders at the time of listing. Lenders and appraisers, in particular, want to see empirical studies demonstrating that an efficient home can command a higher sale price than a comparable non-efficient home, or that price is correlated with relative efficiency. This requires access to empirical data on the home’s energy attributes and performance.
HPC urged RESNET to make data in its National Buildings Registry as open as possible while taking the appropriate security measures to protect sensitive data. We recommended that RESNET define multiple data categories that reflect major use cases for data and/or different levels of data security to more easily and more transparently communicate to stakeholders the types of data that can be accessed and the conditions under which data may be accessed.
We also recommended that RESNET include in its policy a well-defined process for granting access to data that is not publicly available, information on how sensitive data is managed in the National Buildings Registry, the roles and responsibilities of RESNET in managing and protecting data, and the expectation of data users.
