RESNET’s Mortgage Industry National Home Energy Rating Standards (MINHERS) are maintained on a continuous basis and updated with new editions every five (5) years. When addenda implementing amendments are added to an edition of the MINHERS® they are integrated into an official version that is maintained to indicate up-to-date requirements. That version is currently referred to as the Continuous Maintenance Version. It is mobile friendly and may be accessed at https://standards.resnet.us RESNET also maintains the formal editions of the MINHERS® and the individual addenda to those editions including the adoption and implementation dates. See the links below for the MINHERS® 2013 Edition and its addenda.
