Proposed Addendum 59 revises the MINHERS Chapter 2 to set clear HERS Modeler skills criteria for certification of new HERS Raters and recertification of current HERS Raters. Currently certified HERS Raters are grandfathered in as HERS Modelers. However, HERS Modelers are now required to have professional development to retain the certification for modeling HERS Ratings. To maintain consistency in the requirements as well as to improve modeling consistency, the Addendum will require HERS Raters to meet the recertification requirements for HERS Modelers as part of their 18 hours of Professional Development. The HERS Rater training will include HERS Modeler training for new Raters seeking certification and HERS Rater capabilities will include those of a HERS Modeler.
