Detecting energy loss in municipal buildings

Cities struggle to find which public buildings waste heat and electricity outside occupancy hours.

Problem

Facility teams lack bandwidth to review meter data across hundreds of schools and offices.

Monthly utility bills are reviewed; investigations start only after large spikes.

Unnecessary emissions and budget waste.

Models can rank buildings by anomalous night-time load and suggest likely causes (HVAC schedules, leaks).

Meter granularity varies; occupancy data may be missing.

Misattributing causes; privacy if occupancy is inferred too finely.

Energy audits and BMS rule alarms.

Audits are infrequent; BMS rules miss subtle schedule mismatches.
