After years of development and testing the RESNET National Building Registry is now online. The registry will be the depository of information on rated homes. It promises to be the largest source of information on the energy performance of homes in the United States. Accredited RESNET Rating Providers have been asked to start uploading their rating building files into the registry. Beginning on June 15, 2012 in order to print rating reports the building files must have been entered into the national registry. RESNET recognizes there is information in the rating building files that needs to be secured because of privacy and proprietary concerns. During the transitional period RESNET staff will be developing a definition of who can access what information on the registry.
