Show/hide detail on audit types

Category 1 – High Level Audit


  • Documents equipment and identifies energy savings opportunities
  • Includes a full list of all energy consuming equipment at the premises
  • The audit report provides the Customer with high-level estimates of measure costs, energy savings, and payback period sufficient to determine which measures are of interest (these values are estimates based on contractor experience and “rules of thumb”)

Category 2 – Detailed Investment Grade Audit


  • Is limited to only those measures/opportunities Customer selects based on the Category 1 report that the Customer could pursue within 1 year of Category 1 audit
  • Includes full calculations for selected measures, which will be used to determine energy savings, installed costs, incentives, and payback values sufficient for Customers to make decisions to pursue the recommended projects
  • Produces a report and presentation of recommended and actionable options based on Customer requests and requirements

Note - As an Integrated Demand Side Management (IDSM) program, audit scope and report for both the Category 1 & Category 2 audit includes energy efficiency (EE), demand response (DR), and distributed generation (DG) opportunities.
