Large Building Tune-up

(Return to main Building Tune-up page)

If your facility is greater than 75,000 square feet with complex heating, ventilating and air conditioning (HVAC) systems, controlled by an energy management system with comprehensive direct digital control, you may be eligible for SMECO’s Large Building Tune-up Services.

SMECO’s Large Building Tune-up Services are designed for large industrial and commercial electric customers, and program incentives cover up to 75% of the cost of Large Building Tune-up Services with a cap of $30,000 per project. Customers must be willing to match the incentive received, up to $30,000, for Large Building Tune-up Services measures identified with an estimated simple payback of fewer than 1.5 years.

Additionally, up to $5,000 (per project) is available for projects participating in the Large Building Tune-up Program for additional equipment-level metering installed to baseline the equipment before and after the tune-up to verify savings. Project pre-approval is required.

Large Building Tune-up is not appropriate when:

  • Most of the equipment and systems are either outdated or at the end of their service lives.
