A HERO Rating is simply a HERS Rating needed to qualify for the state of Louisiana's Home Energy Rebate Option (HERO) Program.
The HERO Program provided a cash rebate to Louisiana owners of existing single and two-family homes who achieved a 30% improvement in their home’s HERS Score. The amount of the rebate was a maximum of $3,000 (later, $2,000).
Alas, the program ran out of money and is no longer in effect. It could return, at either the state or federal government levels, when politicians muster the wisdom and political will to reduce our dependence on "foreign oil" and create work opportunities for Americans.
