Energy Audit: Support for a free or low-cost building energy audit that achieves at least a 20 percent reduction in energy use, by providing an incentive equal to the cost of the audit (but not more than $200).

Prescriptive Approach: A total of $1,000 for a combination of measures for an audit designed to reduce energy consumption by more than 10 percent; a total of $2,000 for a combination of measures for an audit designed to reduce energy consumption by more than 20 percent.

Performance Approach: A total of $3,000 for demonstrated savings of 20 percent, according to a performance-based building retrofit program; and $1,000 for each additional 5 percentage points of energy savings beyond those listed in the approaches above.
