Board approves second phase of investment-grade audit to identify energy and water savings across 21 schools

The Tucson Unified School District board on Feb. 10 approved the purchase and implementation of the second phase of an investment-grade audit (IGA) intended to identify energy- and water-saving projects at 21 district schools.

Bond manager Dr. Charlotte Carter described the IGA scope: mechanical, structural and electrical engineering assessments; HVAC and large-equipment design; building-automation and controls modeling; water-conservation and irrigation upgrades; insulation and envelope measures; and support for utility rebates and incentive applications. Carter emphasized the IGA is not being paid from the bond program but said its technical findings can be used to maximize bond dollars and reduce maintenance and energy costs over time.

Facilities staff said the IGA is a "boots-on-the-ground" effort that will provide detailed design development and energy-modeling data needed to prioritize projects, target rebates and extend equipment life cycles. The board approved the item by motion and voice vote (5–0).

The audit will produce site-level recommendations that staff expect to use to inform bond implementation and sustainability planning. There was discussion on coordination with the district’s broader climate and sustainability plan and on aligning IGA findings with short- and long-term bond investments.

Staff said the contract will move forward and the district will report back on the audit findings and recommended projects in subsequent bond oversight and board meetings.
