One of the requirements of the Code is that you have a Home Energy Rating System (HERS) index prepared for the residence.  A Preliminary HERS index is prepared based on the plan set and is submitted along with the Checklist to obtain a building permit.  A Final HERS index is prepared once the home is nearly complete and all assumptions in the preliminary HERS index have been verified.  This must be submitted before a Certificate of Occupancy can be issued.  You will need a HERS professional to perform this service.  You can find one either by choosing one from a list we maintain or by visiting the Residential Energy Services Network website which may have a more up-to-date list.
