IID Energy Commercial Rebate Program: These incentives are available to commercial customers to encourage the adoption of energy efficient technologies. Several distinct programs cover general commercial heating and cooling rebates, custom measures and new construction incentives. Customers must retrofit, replace or upgrade old equipment with new, energy-efficient technologies that meet and exceed the current Title 24 standards. Proposed rebate amounts worth a total of $2,500 or more require pre-installation inspection. Some incentives are offered on a flat, per unit basis. However, custom incentives will be awarded based upon the amount of energy saved by the implemented measures.
