District reports $145,000 in first-year savings from Giza energy upgrades; chiller repairs underway
Summary
Facilities staff gave a year‑one update on the district’s Giza energy-efficiency project, reporting that measured savings of about $145,000 exceeded a projected $113,194.
Facilities staff gave a year‑one update on the district’s Giza energy-efficiency project, reporting that the program outperformed its first-year projection and describing follow-up maintenance work.
According to the facilities presentation, projected energy-cost savings for the first year of the Giza project were $113,194; the district’s measured savings were about $145,000. Staff credited much of the improved performance to tighter scheduling and commissioning of the building automation system (BAS), lighting retrofits and more efficient control strategies for HVAC equipment, including installation of variable-frequency drives (VFDs) on motors.
The update listed completed work at multiple campuses: installation of a smaller pool boiler at the high school so the large boiler need not run for pool heating; replacement of domestic hot-water heaters; a new chiller at SRS; 12 heat-pump replacements and lighting upgrades districtwide; and BAS automation and recommissioning that allowed staff to reduce runtime and better sequence equipment. Facilities staff said demand was down in 10 of 12 months (one month’s data was incomplete). Staff also said they worked with the vendor (Pico) on trend analysis and that a vendor representative reviews bills with the district every one-to-two months.
Facilities staff listed follow-up maintenance and projects: a leak repair and vacuuming/recharging effort on chiller #2 at the high school (Divine Brothers contracted to locate and fix the leak), an ongoing investigation into an intermittent shutdown of chiller #1, replacement of a bigger kiln in the art program, and expanded preventive-maintenance schedules (twice-yearly PM for units across the district). Staff said the PM program and trend work should produce additional savings as coil cleaning and airflow tuning improve efficiency.
On district operations and summer work, staff described a number of capital and maintenance tasks scheduled for the break: gym floor refinishing (3–5 day closures per gym), concession-stand work (donation-funded roll-up doors, estimated near $10,000; floor painting estimated near $3,000; sink under $1,000), playground and asphalt repairs, administrative-office reconfigurations and classroom reconfigurations. Facilities staff said some projects are charged to operations (AF Damon seal coating in the operations budget at roughly $1,200,000) and others are capital expenditures (JMC contractors work at about $276,000 charged to capital).
No safety incidents were reported in the presentation. Facilities staff asked the committee for continued support to proceed with scheduled summer work, preventive maintenance and the targeted repairs to the high-school chillers.
