Landed a school district contract in Pittsburgh. 28 buildings ? elementary schools, middle schools, high school, admin building, bus garage, athletic facilities. Every building on its own Duquesne Light meter. School load profiles are extreme: high demand September-May during school hours, near-zero demand June-August when schools are closed, but the ratchet carries summer demand charges from winter peaks. This is 28 separate audits with similar issues.
Demand charge auditing for school districts ? unique challenges
Richard ? school districts are among the best multi-building audit clients because the patterns repeat across buildings. Find a demand issue at one elementary school and the same issue likely exists at all elementary schools. Your per-building audit time drops dramatically after the first few buildings because the findings template applies across the portfolio.
Richard ? in Hartford Ive audited three school districts. The number one finding every time: HVAC schedules not updated to reflect actual school schedules. Schools that start at 7:30am have HVAC systems starting at 5am ? a 2.5 hour warmup that adds demand during pre-dawn hours when the building should be in setback. Adjusting HVAC start times to actual need (6:15am start for 7:30am occupancy) reduced demand at every school by 15-25 kW.
Alice ? checking HVAC schedules across all 28 buildings now. Initial findings: 22 of 28 buildings have HVAC start times 60-90 minutes earlier than necessary. The other 6 are athletic facilities and the bus garage with different schedules. The early HVAC starts add 15-40 kW of demand per building during hours when nobody is there.
Richard ? dont forget summer operations. School buildings often run full HVAC during summer for summer school programs that occupy maybe 10% of the building. The HVAC serves the entire building when only a few rooms are in use. Zone-based summer cooling that conditions only occupied areas can reduce summer demand by 50-70%. Schools that host summer programs are still paying near-full-year demand charges.
School districts in TVA territory get educational institution rates with reduced demand charges. Tennessee schools served through local power companies typically qualify for EDU rates that are 20-30% below standard commercial demand rates. Many school districts were set up on commercial rates when the buildings were first energized and never reclassified. Always check for educational or institutional tariffs.
Vernon ? checked Duquesne Light. They DO have an educational institution rider that reduces the demand charge by 18%. None of the 28 school buildings had the rider applied. The school district financial officer didnt know it existed. Applying the rider to all 28 buildings saves $67,200 annually in demand charges alone. Zero operational changes needed.
Richard ? $67,200 from a tariff rider that was already available! This is why school districts are ideal audit clients. The administrative staff manages budgets but rarely has expertise in utility tariff structures. They accept the bills as presented without questioning the rate classification. Savannah school district was the same ? GPC educational rider unapplied across 19 buildings. $41,000 annual savings once applied.
School district audits exemplify the scalable audit engagement. Richards approach is textbook: 1) Identify the portfolio 2) Find the repeatable patterns 3) Check rate classifications and riders FIRST because they apply to every building simultaneously 4) Then address operational issues building by building. The $67,200 rider finding across 28 buildings illustrates why institutional clients with multiple meters represent the highest-value audit opportunities. One tariff finding multiplied by 28 meters produces a result that would take dozens of individual client audits to match.
