Home Energy Rating System (HERS) Program
The HERS Program was initially implemented to address construction defects and equipment installations that had historically not been done correctly. These HERS measures cover HVAC system and insulation installation.
In an update to the HERS Regulations, the rating of a home as a system (known as Whole House Home Energy Rating) was implemented, where a home is rated on a scale from 0 to 250 to show its efficiency relative to a reference home built to just meet the Title 24 Building Energy Efficiency Standards' prescriptive requirements.
