Controls are shifting from set‑and‑forget to analytics‑first.
Model predictive control (MPC) optimizes setpoints—supply temperature, static pressure, outdoor‑air fraction—against comfort, IAQ, and energy constraints, using weather, occupancy, and tariff forecasts.
Fault detection and diagnostics (FDD) rules, augmented by machine learning, detect stuck dampers, drifting sensors, and valve hunting with quantified confidence scores.
Governance matters.
A common KPI stack aligns engineering and operations: energy intensity (kWh/m² or kWh/ton), system availability, ventilation effectiveness, and IAQ/thermal‑comfort indices.
Dashboards provide drill‑downs from portfolio to equipment; alerts are rate‑limited and routed to work orders in the CMMS.
Procurement includes data‑format requirements (time‑zone stamps, units, tags) so every contractor delivers usable telemetry.
Commissioning is continuous by design.
Sensors are auto‑validated with cross‑checks; trend gaps trigger alarms; and shadow models compare expected to actual performance.
Periodic A/B tests—alternative sequences or reset curves—quantify savings before organization‑wide rollout.
The result is measurable outcomes that withstand audit: lower energy and carbon, fewer complaints, and faster troubleshooting supported by trustworthy data.
