District reports energy-audit results: water savings from smart meters, longer-than-expected solar paybacks

Paul Andrews and his facilities team presented a spring energy-audit update to the board, reporting that electricity and gas consumption and costs were generally consistent year-over-year, while potable and irrigation water usage and costs declined. Staff attributed much of the water improvement to the district's rollout of smart meters, which detect abnormal overnight usage (leaks or stuck valves) and prompt rapid repairs rather than waiting for monthly billing cycles.

On electricity and gas, staff said usage has been fairly consistent and that the district's internal controls help limit cost increases even when statewide rates trend upward. Andrews noted site-specific outliers (higher cost per square foot) are investigated for corrective measures.

Solar installations at three campuses (Union Park, Sandrock, and Schultz) continue to save money, but presenters said payback periods have lengthened from earlier estimates; where conversations previously expected 10–15 year paybacks, current projections show roughly 15–20+ years depending on system degradation and operational factors. Staff said they will continue to monitor system performance and pursue upgrades to building control systems (replacement of unsupported INET systems) over the next two summers to improve efficiency.

Trustees asked questions about timeline and rollout; staff said upgrading controls and achieving full smart-meter coverage across campuses should be complete within the next two summers and that those changes will further reduce water and other operating costs.
